Land and Environment Court Rejects Council's Challenge to Large Housing Development Approvals

The Land and Environment Court dismissed the Council's challenge to the approvals of a concept plan and project application for a large housing development. The court held that the approvals were not unreasonable or manifestly unjust, rejecting the arguments that the approvals were uncertain, based on no evidence, failed to consider relevant factors, or were manifestly unreasonable.

Judgment

Judicial review of PAC's approvals of concept plan and project 1The [NAME] (the Minister) by his delegate, the [NAME] Commission (PAC), approved a concept plan and project application for residential and related development sought by [COMPANY], the Second Respondent, under Pt 3A of the [NAME] Act 1979 (the EPA Act) for land at Warriewood (the site). [COMPANY] , the Third Respondent is the owner of the site and was joined by consent at the hearing. The Second and Third Respondents will be referred to as [NAME] in the judgment. The Applicant, Pittwater Council (the Council), is challenging the approvals of a concept plan and project application in these judicial review proceedings seeking declarations that both approvals are invalid. Four administrative law grounds of judicial review are identified in the Further Amended Summons filed in Court on 24 May 2011 in relation to both approvals.

Relevant statutory provisions - EPA Act Pt 3A 2The Minister can delegate his functions under Pt 3A of the EPA Act, headed "Major Infrastructure and Other Projects", to the PAC under s 23 of the EPA Act. Section 75B(1) and (2) identifies the kinds of projects which may be considered as development under Pt 3A. Under the State [NAME] (Major Development) 2005 Sch 1 [5] cl 13 residential subdivision over $100 million could be declared a Pt 3A project (Sch 1 [5] was repealed effective 13 May 2011). Division 2 concerns project approval and Div 3 concerns concept plan approval. 3Section 75D Div 2 specifies that the Minister's approval is required for a project applied for under this Part. 75E Application for approval of project (1) [NAME] may apply for the approval of the Minister under this Part to carry out a project. (2) The application is to: (a) describe the project, and (b) contain any other matter required by the Director-[NAME]. (3) The application is to be lodged with the Director-[NAME]. (4) An application may relate to part only of a project. 75F Environmental assessment requirements for approval (1) The Minister may, after consultation with the [NAME] the Environment, publish guidelines in the Gazette with respect to environmental assessment requirements for the purpose of the Minister approving projects under this Part (including levels of assessment and the public authorities and others to be consulted). (2) When an application is made for the Minister's approval for a project, the Director-[NAME] is to prepare environmental assessment requirements having regard to any such relevant guidelines in respect of the project. (3) The Director-[NAME] is to notify [NAME] of the environmental assessment requirements. The Director-[NAME] may modify those requirements by further notice to [NAME]. (4) In preparing the environmental assessment requirements, the Director-[NAME] is to consult relevant public authorities and have regard to the need for the requirements to assess any key issues raised by those public authorities. (5) The environmental assessment requirements may require an environmental assessment to be prepared by or on behalf of [NAME] in the form approved by the Director-[NAME]. (6) The Director-[NAME] may require [NAME] to include in an environmental assessment a statement of the commitments [NAME] is prepared to make for environmental management and mitigation measures on the site. (7) This section is subject to section 75P. Note. Section 75P enables the Minister to determine environmental assessment requirements for approval to carry out the project or any stage of the project when giving approval to a concept plan for the project under Division 3. 75G (repealed ) 75H Environmental assessment and public consultation (1) [NAME] is to submit to the Director-[NAME] the environmental assessment required under this Division for approval to carry out the project. (2) If the Director-[NAME] considers that the environmental assessment does not adequately address the environmental assessment requirements, the Director-[NAME] may require [NAME] to submit a revised environmental assessment to address the matters notified to [NAME]. (3) After the environmental assessment has been accepted by the Director-[NAME], the Director-[NAME] must, in accordance with any guidelines published by the Minister in the Gazette, make the environmental assessment publicly available for at least 30 days. (4) During that period, any person (including a public authority) may make a written submission to the Director-[NAME] concerning the matter. (5) The Director-[NAME] is to provide copies of submissions received by the Director-[NAME] or a report of the issues raised in those submissions to: (a) [NAME], and (b) if the project will require an environment protection licence under Chapter 3 of the Protection of the Environment Operations Act 1997 -the Department of Environment, Climate Change and Water, and (c) any other public authority the Director-[NAME] considers appropriate. (6) The Director-[NAME] may require [NAME] to submit to the Director-[NAME]: (a) a response to the issues raised in those submissions, and (b) a preferred project report that outlines any proposed changes to the project to minimise its environmental impact, and (c) any revised statement of commitments. (7) If the Director-[NAME] considers that significant changes are proposed to the nature of the project, the Director-[NAME] may require [NAME] to make the preferred project report available to the public. 75I Director-[NAME]'s environmental assessment report (1) The Director-[NAME] is to give a report on a project to the [NAME] the purposes of the Minister's consideration of the application for approval to carry out the project. (2) The Director-[NAME]'s report is to include: (a) a copy of [NAME]'s environmental assessment and any preferred project report, and (b) any advice provided by public authorities on the project, and (c) a copy of any report of the [NAME] Commission in respect of the project, and (d) a copy of or reference to the provisions of any State [NAME] that substantially govern the carrying out of the project, and (e) except in the case of a critical infrastructure project-a copy of or reference to the provisions of any environmental [NAME] instrument that would (but for this Part) substantially govern the carrying out of the project and that have been taken into consideration in the environmental assessment of the project under this Division, and (f) any environmental assessment undertaken by the Director-[NAME] or other matter the Director-[NAME] considers appropriate, and (g) a statement relating to compliance with the environmental assessment requirements under this Division with respect to the project. 75J Giving of approval by Minister to carry out project (1) If: (a) [NAME] makes an application for the approval of the Minister under this Part to carry out a project, and (b) the Director-[NAME] has given his or her report on the project to the Minister, the Minister may approve or disapprove of the carrying out of the project. (2) The Minister, when deciding whether or not to approve the carrying out of a project, is to consider: (a) the Director-[NAME]'s report on the project and the reports, advice and recommendations (and the statement relating to compliance with environmental assessment requirements) contained in the report, and (b) if [NAME] is a public authority-any advice provided by the Minister having portfolio responsibility for [NAME], and (c) any findings or recommendations of the [NAME] Commission following a review in respect of the project. (3) In deciding whether or not to approve the carrying out of a project, the Minister may (but is not required to) take into account the provisions of any environmental [NAME] instrument that would not (because of section 75R) apply to the project if approved. However, the regulations may preclude approval for the carrying out of a class of project (other than a critical infrastructure project) that such an instrument would otherwise prohibit. (4) A project may be approved under this Part with such modifications of the project or on such conditions as the Minister may determine. (5) The conditions of approval for the carrying out of a project may require [NAME] to comply with any obligations in a statement of commitments made by [NAME] (including by entering into a [NAME] agreement referred to in section 93F).

Division 3 Concept plans for certain projects 75M Application for approval of concept plan for project (1) The Minister may authorise or require [NAME] to apply for approval of a concept plan for a project. (2) The application is to: (a) outline the scope of the project and any development options, and (b) set out any proposal for the staged implementation of the project, and (c) contain any other matter required by the Director-[NAME]. A detailed description of the project is not required. (3) The application is to be lodged with the Director-[NAME]. (3A) A single application may be made for approval of a concept plan for a project and for approval to carry out any part or aspect of the project. In that case, environmental assessment requirements, public consultation and reports under this Division and Division 2 with respect to the project may be combined. (4) If an environmental [NAME] instrument requires the preparation of a development control plan before any particular or kind of development is carried out on any land, the obligation may be satisfied for a project by an application for approval and approval of a concept plan in respect of the land concerned (but only if the Minister authorises or requires an application for approval of the concept plan). 75N Environmental assessment, public consultation and Director-[NAME]'s report for concept plan Sections 75F (Environmental assessment requirements for approval), 75H (Environmental assessment and public consultation) and 75I (Director-[NAME]'s environmental assessment report) apply, subject to the regulations, with respect to approval for the concept plan for a project in the same way as they apply with respect to approval to carry out a project. 75O Giving of approval for concept plan (1) If: (a) [NAME] makes an application for the approval of the Minister under this Part of a concept plan for a project, and (b) the Director-[NAME] has given his or her report on the project to the Minister, the Minister may give or refuse to give approval for the concept plan for the project. (2) The Minister, when deciding whether or not to give approval for the concept plan, is to consider: (a) the Director-[NAME]'s report on the project and the reports and recommendations (and the statement relating to compliance with environmental assessment requirements) contained in the report, and (b) if [NAME] is a public authority-any advice provided by the Minister having portfolio responsibility for [NAME], and (c) any findings or recommendations of the [NAME] Commission following a review in respect of the project. (3) In deciding whether or not to give approval for the concept plan for a project, the Minister may (but is not required to) take into account the provisions of any environmental [NAME] instrument that would not (because of section 75R) apply to the project if approved. However, the regulations may preclude approval for a concept plan for the carrying out of a class of project (other than a critical infrastructure project) that such an instrument would otherwise prohibit. (4) Approval for a concept plan may be given under this Division with such modifications of the concept plan as the Minister may determine. (5) Approval for the concept plan may be given under this Division subject to satisfactory arrangements being made, before final approval is given for the project or any stage of the project under this Part or under the other provisions of this Act, for the purpose of fulfilling the obligations in a statement of commitments made by [NAME] (including by entering into a [NAME] agreement referred to in section 93F). 75P Determinations with respect to project for which concept plan approved (1) When giving an approval for the concept plan for a project, the Minister may make any (or any combination) of the following determinations: (a) the Minister may determine the further environmental assessment requirements for approval to carry out the project or any particular stage of the project under this Part (in which case those requirements have effect for the purposes of Division 2), (b) the Minister may determine that approval to carry out the project or any particular stage of the project is to be subject to the other provisions of this Act (in which case the project or that stage of the project ceases to be a project to which this Part applies), (c) the Minister may determine that no further environmental assessment is required for the project or any particular stage of the project (in which case the Minister may, under section 75J, approve or disapprove of the carrying out of the project or that stage of the project without further application, environmental assessment or report under Division 2). (1A) The further requirements for approval to carry out the project or any part of the project that the Minister may determine under subsection (1) (a) are not limited to matters that the Director-[NAME] may require under Division 2. ... 75X Miscellaneous provisions relating to approvals under this Part ... (3) The Minister may, but is not required to, give reasons to [NAME] for: (a) any disapproval, or conditions or modifications, of a project, or (b) any disapproval, or modifications of, a concept plan for a project, or (c) any conditions of approval of a modification of the approval of a project. ... (5) The only requirement of this Part that is mandatory in connection with the validity of an approval of a project or of a concept plan for a project is a requirement that an environmental assessment with respect to the project is made publicly available under section 75H (or under that section as applied by section 75N). This subsection does not affect the operation of section 75T in relation to a critical infrastructure project. Clause 8B of the [NAME] 2000 (the Regulation) provides: Matters for environmental assessment and Ministerial consideration The Director-[NAME]'s report under section 75I of the Act in relation to a project is to include the following matters (to the extent that those matters are not otherwise included in that report in accordance with the requirements of that section): (a) an assessment of the environmental impact of the project, (b) any aspect of the public interest that the Director-[NAME] considers relevant to the project, (c) the suitability of the site for the project, (d) copies of submissions received by the Director-[NAME] in connection with public consultation under section 75H or a summary of the issues raised in those submissions. Note. Section 75J (2) of the Act requires the Minister to consider the Director-[NAME]'s report (and the reports, advice and recommendations contained in it) when deciding whether or not to approve the carrying out of a project.

Evidence - [NAME] history 4The parties tendered an agreed bundle of documents which contained all the relevant [NAME] history of the site. The site is located near the Warriewood Sewerage Treatment Plant (STP) and identified as buffer area 3 in various [NAME] instruments made by the Council. Under Pt 3A s 75J(3), when giving approval for a project the Minister may but is not required to take into account the provisions of any environmental [NAME] instrument. A similar provision appears in s 75O(3) in relation to the giving of concept plan approval by the Minister. There is no disagreement amongst the parties about the events leading up to the approvals by the PAC. The parties usefully agreed a chronology of relevant events including a reference to the documents in the tendered bundle and identifying the provision in the EPA Act a particular document addresses.

5While the chronology refers to [NAME] lodging a project application under s 75E and an application for a concept plan approval under s 75M the two were considered together throughout the assessment process and in the PAC's determination. When the project was declared to be within Pt 3A the Director-[NAME] of [NAME] (the [NAME]) also resolved that a concept plan could be submitted. The [NAME]'s environmental assessment requirements (DGEAR) issued on 23 December 2009 refer to both as does [NAME]'s environmental assessment ([NAME]), the [NAME]'s environmental assessment report ([NAME]'s report) and the Department's supplementary report. The parties agreed in final submissions that under s 75M(3A) a single application can be made for approval of a concept plan and a project. Under s 75N [NAME] required under s 75F, the [NAME] prepared under s 75H and the [NAME]'s report for a project required under s 75I also applies to a concept plan. The two applications travelled together, were assessed together as provided for in s 75N in relation to s 75F, s 75H and s 75I and determined together on the basis of the same reasons. 6The Court was taken through a number of the [NAME] instruments and reports in the agreed chronology referred to below by the Respondents' submissions.

Pittwater Local Environmental Plan 1993 (the LEP)/Development Control Plan No 21 (DCP 21) 7Under the LEP the site is identified as one of three buffer areas around the Warriewood STP (buffer area 3). The site is zoned 2(f) (urban purposes-mixed residential). Residential buildings are permitted with development consent. Under cl 30C no more than 142 dwellings or fewer than 135 dwellings are permitted in buffer area 3, a density of 17 - 18 dwellings per hectare. The DCP 21 specifies a building height of 2 - 3 storeys for the site.

[NAME] 2007 8The draft [NAME] which was publicly exhibited in 2007 refers to a target of 4,600 new dwellings in the [NAME] area to be constructed by 2031. It was prepared in response to the Metropolitan Strategy for Sydney to 2031 released in December 2005 (the Metropolitan Strategy 2005).

DGEAR 1, 4 and 5 (s 75F, 75N) 23 December 2009 9The DGEAR specify what matters [NAME] was required to address in its [NAME] as required under s 75F(2). The Council's case relies on the alleged failure by the PAC to consider matters in DGEAR 1, 4 and 5 which state as follows: 1.Relevant EPI's policies and guidelines to be [NAME] provisions applying to the site, including permissibility and the provisions of all plans and policies are contained in appendix A.... Appendix A refers to the NSW State Plan, draft [NAME], the LEP (including DCP 21) and [NAME] 1997 and the [NAME], inter alia.

4. Land uses and Density Identify the range of land uses proposed, and demonstrate consistency with the objectives of the "2(f) (Urban Purposes - Mixed Residential)" zone. In particular, the [NAME] should justify the intensity of non-residential uses proposed in Stage 1 and in the later stages of the Concept Plan. Provide justification for the proposed dwelling yield and floor space.

5. Isolated Sites The proposal should seek to amalgamate with the adjacent properties known as 5 and [ADDRESS] so that there is a more appropriate and reasonable relationship with future developments in the locality. The [NAME] and [sic] shall include details outlining negotiations with the owners of the affected properties. In the event that amalgamation is not possible, the [NAME] shall address development potential of the isolated sites if they cannot be included within this proposal.

[NAME] 10Meriton produced an [NAME] in March 2010 which provided a summary of the project and concept plan, a summary of [NAME] and consideration of these, [NAME] background, site assessment, strategic justification of the project and concept plan including reference to the Metropolitan Strategy 2005 and the draft [NAME] and the LEP dwelling yield assessment. The report also includes a height assessment, s 7.4 considers isolated sites. Correspondence with neighbouring owners and their responses were attached. A concept plan diagram was included which addresses the development potential of the adjoining sites. A report entitled [ADDRESS], Warriewood: Traffic Impact Assessment and Transport Accessibility and Management Plan dated 12 February 2010 prepared by [NAME] for [NAME] was also submitted with the [NAME].

Pittwater [NAME] 2010 11The [NAME] framework report prepared by the Council recommended 25 dwellings per hectare for the buffer area around the STP including this site and a revised figure of 186 dwellings in total for buffer area 3. There was no recommendation in relation to building height.

[NAME] Review report August 2010 (the [NAME] report) 12The [NAME] report was commissioned by the Department of [NAME] (the Department). It was relied on by the Department as a strategic justification for increasing the residential density of the Warriewood buffer areas prepared for the Department, and was completed in August 2010. It recommended a site density of 81 dwellings per hectare and building heights of up to five storeys in the Warriewood Valley buffer areas including the site.

[NAME] Report ([NAME] traffic report) November 2010 13A traffic report dated November 2010 was also prepared for the Department by [NAME]. The independent study modelled different scenarios for density, consistent with the [NAME] and increased densities similar to those proposed by [NAME]. Scenario 2 was higher density in the buffer areas than allowed for in the [NAME] being 655 total dwellings in buffer area 3 (approximately 81 dwellings per hectare). If that scenario were to be pursued, the report recommended "additional upgrading of the [ADDRESS]/[ADDRESS] intersection, beyond that assumed" in the study would need to be further investigated.

[NAME]'s Preferred Project Report (PPR) September 2010 (s 75H(6)(b), 75N) 14The PPR follows the public exhibition of the [NAME] and makes changes to the project and concept plan. Building heights of partly three, four and five storeys and density of 75 dwellings per hectare are proposed.

Council's submission on the PPR October 2010 15The Council was critical of the PPR in its submission to the Department in part because it disregards the outcomes of the Metropolitan Strategy 2005, the draft [NAME] and the [NAME] (25 dwellings per hectare). The Subregional Strategy was informed by the Metropolitan Strategy 2005 in providing for 4,600 dwellings in the [NAME] area by 2031 which target can be accommodated under current [NAME] strategies. The increased density of development proposed by [NAME] is not required to meet the housing targets in the metropolitan and subregional strategies. The PPR yield of 559 dwellings greatly exceeds the 142 dwellings permitted under the LEP and the 186 dwellings permitted under the [NAME]. Criticism is made of the [NAME] report in part because it is limited to the three buffer areas and there is no assessment of likely impacts of increased density outside these areas. There is also an assessment of compliance against the LEP controls.

Director-[NAME]'s environmental assessment report ([NAME]'s report) (s 75I, s 75N report) November 2010 16The [NAME]'s report dated November 2010 is a substantial document which provides background to the proposed project and the [NAME] history of the site, and identifies surrounding development. The PPR consisting of the concept plan and the Stage 1 project application is discussed. The strategic [NAME] context refers to the NSW State Plan 2010, Metropolitan Strategy 2005, the draft [NAME] 2007, the [NAME] report (appendix 5) and the [NAME] traffic report (appendix 5). In relation to density (section 6.1) the report states the proposal for 559 dwellings exceeds the maximum dwelling yield limits set by the Council's LEP of 140 dwellings and notes the more recent [NAME] has a revised yield of 186 dwellings. Built form and height are considered with the report stating that the proposal has been designed to respond to the future character and context of the area and the site's environmental capability. Street front buildings are limited to three storeys with four and five storeys located toward the centre to minimise visual impact when viewed externally. 17The report responded to the Council's objections based on equity and precedent given significant departures from existing [NAME] controls, inadequate infrastructure for such unplanned development, impacts on amenity and the environment, traffic and public transport inter alia, in appendix 7. It considered the scheme should be approved at the density applied for namely 75 dwellings per hectare, which is supported by the [NAME] report, and is in the public interest as it provided additional housing, public open space, environmental improvements and local road improvements, inter alia. 18The statutory context of Pt 3A of the EPA Act is identified in appendix 6 which includes a statement of compliance to the effect that in accordance with s 75I of the EPA Act and cl 8B of the [NAME] 2000 (the EPA Regulation) the Department is satisfied that [NAME] have been complied with. Appendix 6 refers to the principles of ecologically sustainable development, environmental [NAME] instruments such as State [NAME] (SEPPs) and any environmental [NAME] instrument which would, except for the application of Pt 3A, govern the carrying out of the project and have been taken into consideration in the assessment of the project. Four SEPPs including the NSW Department of [NAME]'s Residential Flat Design Code dated September 2002 are identified as relevant together with the LEP.

Metropolitan Strategy for Sydney 2036 released 16 December 2010 19The [NAME] states: The Metropolitan Plan for Sydney 2036 aims to guide the growth of Australia's leading city towards greater sustainability, affordability, liveability and equity for generations to come.... More Suitable and Affordable Housing (p 654) While Sydney's population is growing, the average household size is falling, creating demand for more - but smaller, more affordable - homes. As a result, Sydney will need 770,000 additional homes by 2036 - a 46% increase on the city's current 1.68 million homes. The location, size and type of new housing must reflect the population's growing needs. Housing Sydney's population (p 656) Plan for 770,000 additional homes with a range of housing types, sizes and affordability levels for a growing and ageing population. Locate at least 70% of new homes in existing suburbs and up to 30% in Greenfield areas. Drive delivery through subregional targets and Local Environment Plans with follow-through on outcomes and yield Policy settings (p 663) This Metropolitan Pan is an integrated, long-term [NAME] framework that will sustainably manage Sydney's growth and strengthen its economic development to 2036 while enhancing its unique lifestyle, heritage and environment. 20Strategic Direction B considers growing and renewing centres including local centres. A series of actions to achieve this are identified. Action B1.2 is to establish appropriate mechanisms in subregional strategies to provide sufficient capacity for commercial development in centres. The subregional level work will be used in the preparation of LEPs. Strategic Direction D concerns housing Sydney's population with all centres to have a minimum level of medium density with low density reserved for heritage or physically constrained areas. Smaller local centres are suited to low-medium rise medium density housing. The aim it is to locate 80 per cent of all new housing within walking distance of centres of all sizes. Low, medium and high rise development is described as follows: Low rise: Three storeys or less. Includes terraces, townhouses, shop-top housing, semi-detached housing and small residential flat buildings. Medium rise: Four to five storeys. Includes residential flat buildings and shop-top housing. High rise: Six storeys or more. Includes residential flat buildings, shop-top housing and large mixed use developments such as offices and shops with housing above. Low density is fewer than 25 dwellings per hectare. Medium density is 25-60 dwellings per hectare. High density is more than 60 dwellings per hectare. 21Action D2.1 aims to ensure that local [NAME] controls include more low rise medium density housing in and around smaller local centres. Low rise medium density development is particularly encouraged around small local centres. Strategic Direction I is called Delivering the Plan. The plan is intended to be implemented by state involvement in implementation of spatial plans via local government through subregional strategies, LEPs, directions under s 117 of the EPA Act, inter alia. Objective I3 refers to the alignment of subregional [NAME] with the strategic directions of the plan. Objective I4 identifies LEPs as the primary land use [NAME] tool for delivering mandatory development controls. The Minister will issue a new s 117 direction under the EPA Act to ensure new LEPs respond to the plan.

PAC's determination 18 January 2011 22The PAC provided a single written determination for the two applications for approval before it. The executive summary records that the PAC considered the documentation provided by the Department, matters raised in meetings held with the Department, the [NAME] and additional strategic justification for the proposal provided by the Department. The PAC members visited the area. The PAC considered that a strategic study of undeveloped sites in the Warriewood Valley was warranted including the development potential around Warriewood Centre. There is a need to increase housing stock in Metropolitan Sydney and in each subregion to meet housing demand from a growing population and changing household requirements. The PAC "takes its lead" from the [NAME] and approves the concept plan subject to modifications limiting building height generally to three storeys and development densities to a maximum of 60 dwellings per hectare. That height is considered compatible with surrounding streetscape and the density is sustainable given the location. The project application for stage 1 was also approved subject to the modified concept plan and conditions. 23Section 1 includes a description of the proposal in the concept plan and the stage 1 project application, a brief [NAME] history of Warriewood Valley and of the site. The documents before the PAC were listed in section 3.0 Information Available to the Commission as including: (i)[NAME] (ii)The Council's consent number 526/08 and approved site layout (iii)[NAME]'s response to submissions (iv)[NAME] report August 2010 (v)[NAME] traffic report 11 November 2010 (vi)Review of development contribution rates by the Department 26 October 2010 (vii)[NAME]'s statement of commitments dated 12 November 2010 for the concept plan and project application (viii)The recommended conditions of consent (ix)Submissions received by the Department, a total of 545 during the exhibition of the [NAME] and a further five were received in relation to [NAME]'s PPR 24A summary of submissions made at the meetings with the Department, the [NAME] and additional information made available to the PAC by way of a strategic justification for increased residential density report was provided on 10 December 2010. 25In section 7 "Key Issues" the PAC identifies the strategic justification for increased density and height, the impacts on transport and traffic, and environmental implications. Section 7.1 "Strategic Justification" records that the [NAME] states that 770,000 additional homes will be required across the Sydney metropolitan area by 2036 and that 70 per cent of these homes should be provided within existing urban areas. The draft [NAME] calls for 4,600 new dwellings in the [NAME] area by 2031. While the Council indicated it could accommodate these dwellings under its existing plans, the PAC notes housing requirements have increased since the release of the draft Subregional Strategy and it is likely additional housing will be required in the [NAME] area. The [NAME] identifies the site as capable of supporting medium density residential development up to a density of 25 dwellings per hectare. This was considered unduly restrictive. The [NAME] report was considered too limited in scope to provide a proper basis for a density of 81 dwellings per hectare. 26The PAC strongly recommended that the Council and the Department of [NAME] work together to jointly prepare a comprehensive strategic study of the whole Warriewood Valley. In the absence of such a study and in order not to unreasonably delay a determination of the applications in considering the merits of the project, the PAC "takes its lead" from the [NAME] as guiding its conclusions regarding the appropriate development density and height at the site. The PAC considered the site could be developed in the range of medium density identified in the [NAME] and that a three-storey limit is appropriate with a fourth storey on certain buildings in the centre of the site as the natural ground level slopes down from the street. 27The PAC set out its conclusions in section 8 approving the concept plan subject to modifications restricting building height to three storeys and limiting development density to 60 dwellings per hectare. The stage 1 project application was also approved with the same modifications in relation to this aspect of the approval.

Concept approval issued under s 75O of the EPA Act 28On 18 January 2011 the PAC issued concept approval for stage 1 of "a residential and child care development" including multi-unit housing development and childcare centre, private and public open space, parking, road works, pedestrian and cycle pathway, landscaping and ecological rehabilitation works. 29Schedule 2 Pt A condition 2 approves specified plans subject to modifications required under s 75O(4) specified in Part B modifications 1 - 4. Modification 2 was referred to by the Council. 1 Environmental Zones The plans described above in Part A - Terms of Approval (2) shall be modified as follows: The Asset Protection Zone shall be maintained as an Inner Protection Area with a minimum width of 25 metres, exclusive of the 10 metre wide Vegetated Wetland Buffer Zone. The Bio-Retention Basin B and [ADDRESS] adjoining Building P shall be relocated clear of the 10 metre Vegetated Buffer Zone. The building envelopes of Buildings O and P shall be amended to accord with the above environmental zone modifications. The north eastern wall of Building O shall not extend past its existing location. Amended plans demonstrating compliance with this modification shall be submitted to, and approved by, the Director [NAME]. 2 Density and Height The plans described above in Part A - Terms of Approval (2) shall be modified as follows: (a)The dwelling yield is limited to a maximum of 60 dwellings per hectare. Note: For the purposes of calculating the dwelling yield, the site area is the developable area of 7.45ha and excludes Fern Creek and the creekline corridor. (b) The height of the development shall be limited to 3 storeys, with the exception of Buildings D, E, F, G, K, L, and M which may be permitted to be a maximum of 4 storeys to achieve the maximum density specified in Modification 2a above, subject to: (i)Any 4 th storey having a smaller footprint than the 3 rd level below to provide articulation to the building form; (ii)Any change to the siting or form of the envelopes resulting from Modification 2a and/or 2b shall maintain compliance with the relevant provisions of the Residential Flat Design Code; and (iii)The amendment shall maintain a minimum of 50% of the developable area of 7.45ha as deep soil area. Amended plans demonstrating compliance with these modifications shall be submitted to, and be approved by the Director [NAME]. 3 Minimum Public Open Space The redevelopment or the site shall provide a minimum of 15,601m 2 of publicly accessible open space to be dedicated to Pittwater Council as shown in the plan attached to [NAME]'s letter dated 11 November 2010. 4 Inconsistencies between Documentation In the event of any inconsistency between modifications of the Concept Plan approval identified in this approval and the drawings/documents including the Revised Statement of Commitments, the modifications of the Concept Plan shall prevail. 30Schedule 3 provided future environmental assessment requirements and Sch 4 referred to the statement of commitments in the PPR.

Project approval issued under s 75J of the EPA Act 31The 18 January 2011 project approval was issued by the PAC for: Stage 1 for a residential and child care development including: Demolition of the existing buildings and structures on site and tree removal; Excavation, earthworks and flood mitigation works; Construction of 7 residential buildings of 3, 4 & 4 storeys in height providing 295 apartments with associated pools and gymnasium; Basement parking for 471 cars comprising 429 resident car spaces and 42 visitor spaces; Single storey childcare centre (270m 2 ); External road works, internal public access roads and public pedestrian and cycle way; Asset Protection Zone, Environmental Buffer areas and ecological rehabilitation and landscaping works. 32Schedule 2 Pt A identifies approval is to be in accordance with specified plans except as modified by the conditions of approval. Part B details numerous modifications including: B1 Density and Height Modifications The plans described above in Terms of Approval (A1) shall be modified as follows: (a)The dwelling yield is limited to a maximum of 60 dwellings per hectare. Note: For the purposes of calculating the dwelling yield, the site area is the developable area of 7.45ha and excludes Fern Creek and the creekline corridor. (b)The height of the development shall be limited to 3 storeys, with the exception of Buildings D, E, F and G which may be permitted to be a maximum of 4 storeys to achieve the maximum density specified in Condition B1(a) above, subject to: (i)Any 4 th storey having a smaller footprint than the 3 rd level below to provide articulation to the building form; (ii)Any change to the siting or form of the envelopes resulting from Conditions B1(a) and/or B1(b) shall maintain compliance with the relevant provisions of the Residential Flat Design Code; and (iii)The amendments shall maintain a minimum of 50% of the developable area of 7.45ha as deep soil area. Amended plans demonstrating compliance with these modifications shall be submitted to, and approved by the Director [NAME]. (Identical to modification 2 in the concept plan approval except it applies only to stage 1 consisting of seven buildings.) 33B3 concerned carpark and service vehicle layout and B13 concerned car and bicycle parking provisions and storage.

Approved plans - Notices of Motion (NOM) after hearing 34The PAC determination imposed identical conditions modifying the change of building form for the concept plan and project, the only difference being the number of buildings reflecting that stage 1 is seven buildings (project stage 1) and stage 2 a further seven buildings (concept plan, stages 1 and 2). The conditions imposed require the submission of amended plans by [NAME] to the [NAME] to reflect the final determination of the PAC in relation to the reduction of density and height of buildings from that sought by [NAME]. The [NAME] approved plans submitted by [NAME] on 23 March 2011. During the hearing the [NAME] sent a letter dated 24 May 2011 to [NAME] which stated that the plans approved on 23 March 2011 were beyond the scope of what had been authorised by the PAC, the conditions for the project and concept approvals so that he considered the approvals notified on 23 March 2011 were not an approval (exhibit 1). The Minister informed the Court that the [NAME] considered that the approval of the plans by the [NAME] had no legal effect relying on [NAME] Immigration and Multicultural Affairs v Bhardwaj [2002] HCA 11; (2002) 209 CLR 597 because the amendments went beyond what the PAC authorised being changes limited to height and density as stated in the letter. [NAME] did not appear to accept that this was the legal position in relation to the plans and suggested the validity of the [NAME]'s decision would be tested elsewhere. 35After the hearing had been completed and judgment reserved [NAME] filed a NOM dated 14 June 2011 seeking leave to reopen its case to adduce further evidence, as contained in the affidavit of [NAME], solicitor, dated 14 June 2011. Leave was granted to do so and further written submissions were provided by [NAME] and the Council. The evidence identifies three further applications by [NAME] to the [NAME] to have plans and drawings approved by the [NAME] which comply with the PAC conditions of approval for firstly, the project, and secondly, the concept plan. Thirdly, an application to modify the project under s 75W of the EPA Act to allow for changed floor plan layouts in a number of units and changes in carparking was also made. The first and second applications were approved by the [NAME] on 6 June 2011. 36A further NOM dated 29 July 2011 was filed by [NAME] which sought leave to rely on the evidence contained in the affidavit of [NAME], solicitor, dated 25 July 2011 and to make submissions to the Court. The Council responded with written submissions also and consented to the matter being dealt with in chambers. The material attached to the affidavit in support is the PAC's determination made on 15 July 2011 to approve the application under s 75W for modifications to the residential development at 14 - [ADDRESS], Warriewood. The modifications sought were a reduction of one level of basement parking and amendment of the floor layout of units in buildings A, B and C to include a study in some apartments. The power to determine the modification was delegated to the PAC by the Minister on 28 May 2011.

Ground of challenge - PAC's approvals were uncertain

Council's submissions 37As identified in the Further Amended Points of Claim filed in Court on 24 May 2011, the Council alleges that in purporting to grant the project approval and the concept plan approval subject to conditions requiring the preparation of amended plans which would decrease the number of dwellings, the height of buildings and their positioning and make other design modifications, the conditions imposed were uncertain or amount to impermissible delegation to the [NAME] of the PAC's function. This falls outside the power of the Minister to impose conditions on a project approval under s 75J(4) or on a concept plan under s 75O of the EPA Act. 38Both the concept plan approval and the project approval provided that the height of the development shall be limited to three storeys, with the exception of buildings D, E, F, G (stage 1 project and concept plan), K, L and M (stage 2 concept plan) which may be permitted to a maximum of 4 storeys to achieve the maximum density of 60 dwellings per hectare subject to: (a) Any fourth storey having a smaller footprint than the third level below to provide articulation to the building form; (b) Any change to the siting or form of the envelopes resulting from conditions B1(a) and B1(b) shall maintain compliance with the relevant provisions of the Residential Flat Design code: and (c) The amendments shall maintain a minimum of 50 per cent of the developable area of 7.54 hectare as deep soil area. 39The [NAME] appears to be empowered by the PAC to approve any modified plans which conform to the modifications imposed by the PAC. This is not authorised by the Act. Mison v Randwick Municipal Council (1991) 23 NSWLR 734 per [NAME] ([NAME] concurring) held that where important aspects were not determined this could alter the proposed development in a fundamental respect. Transport Action Group Against Motorways v Roads and Traffic Authority [1999] NSWCA 196; (1999) 46 NSWLR 598 holds that a modification must also be certain. Other relevant authorities are [COMPANY] v [NAME] [2008] NSWLEC 185; (2008) 160 LGERA 20 , Kindimindi Investments Pty Ltd v Lane Cove Council [2006] NSWCA 23 ; (2006) 143 LGERA 277 and [NAME] v [NAME] [2007] NSWLEC 741; (2007) 157 LGERA 124 at first instance. [NAME] should be distinguished on the facts of this case where the concept approval and project approval have travelled together. They should stand or fall together under this ground. Alternatively, if the Respondents succeed in relation to the concept plan approval, the project approval can still be found to be uncertain under s 75J. The modifications in the project approval and concept plan approval repose in the [NAME] a discretion to approve or reject any modified plans that [NAME] might submit. The PAC has effectively delegated its own function of approval to the [NAME] which is contrary to the Act, which proceeds on the basis that the major projects to which Pt 3A applies will be determined personally by the Minister. 40Further, and significantly, by introducing these modifications the PAC has left open to [NAME] a wide leeway of possible modifications, all of which might fall within the very [NAME] spectrum of plans that purport to have been approved. The introduction of these modifications is contrary to the notions of finality discussed in [NAME] . The question ultimately is whether s 75J and s 75O authorise the conditions which leave to [NAME] and the [NAME] the wide measure of choice involved. 41In submissions on the first day while accepting this was not essential in its case relying on the terms of the condition B1, the Council relied on the plans which were approved by the [NAME] on 23 March 2011 to show the extent of changes which were approved. A number of these went beyond changes to heights of buildings and reduction of density, such as the change in an underground carpark from two levels to one with shape and footprint changed and most of the parking stacked and no disabled parking, reducing bicycle storage areas, and the reconfiguration of floor layouts in all buildings indicated with the introduction of studies instead of a bedroom in a number of units, inter alia. 42Following the first NOM dated 14 June 2011 filed by [NAME] after the hearing concerning the approval of further plans by the [NAME], the Council submitted that this new evidence did not advance [NAME]'s case. The s 75W application is irrelevant to the matters before the Court. Whether the PAC permits or refuses the modification application has no bearing on the issues in the proceedings. Notwithstanding the most recent applications for amended plans to be approved lodged by [NAME] it has not retreated from its original position that the plans approved on 23 March 2011 were supported by the concept plan approval and the project approval. If the Court finds that the plans purportedly approved on 23 March 2011 demonstrate the very [NAME] range of uncertain matters left to the [NAME] for decision, [NAME] should not be permitted to say that the amended plans were not supported by the concept and project approvals. 43In relation to the second NOM filed by [NAME] dated 29 July 2011 concerning the approval by the PAC of the s 75W modification application, the Council submitted this material is irrelevant to the issues to be determined by the Court. The s 75W determination is not evidence that the works the subject of the modification application did not arise from the concept or project approval. [NAME]'s position is that the applications originally made to the [NAME] approved on 23 March 2011 were within the wide discretion afforded under the project and concept plan approvals granted by the PAC. Nor is the approval of the modification sought relevant to the exercise of the Court's discretion.

Minister's submissions 44Section 75J provides the power to the Minister, here the PAC, to impose conditions on a project approval, and under s 75O modifications on a concept plan approval under Pt 3A of the EPA Act. The conditions, terms of approval and modifications were not uncertain or fell outside the power of the Minister under s 75J and s 75O. 45The Minister submits that the following principles apply to the determination of this ground of challenge: a."... there is no common law principle that an exercise of statutory power must be certain or final in order to be valid." [NAME] per [NAME] at [49]. b."... a condition will only be invalid, by lacking certainty or finality, if it falls outside the class of conditions which the statute expressly or impliedly permits." [NAME] at [50]; [COMPANY] v [NAME] [2009] NSWLEC 213; (2009) 178 LGERA 347 per [NAME] at [50]. c."[NAME] ambiguity or uncertainty of the meaning of words does not necessarily lead to invalidity. Courts try to avoid uncertainty by adopting a construction which gives statutory instruments and decisions practical effect." [NAME] at [66]. d."... the power to grant approval on conditions in s 75J of the Act, neither expressly nor impliedly requires, in order for a condition to be valid, that a condition set the parameters for adjustment of a project to achieve an outcome or an objective specified in the conditions. The power to impose conditions on an approval under Part 3A of the Act is not confined in the manner specified for conditions of development consent under Part 4 of the Act (see sections 80 and 80A of the Act). The power to grant approval under s 75J is expressly stated to be able to be exercised, first, "with such modifications of the project" and, secondly, "on such conditions", as the Minister may determine in both cases." [NAME] at [74]. e."The power to impose conditions on an approval under Part 3A is wide." [NAME] at [74]. f."Retention of practical flexibility, leaving matters of detail for later determination and delegation of supervision of some stage or aspect of the development, may all be desirable and be in accordance with the statutory scheme." [NAME] at [78]. g."The scale of the projects subject to approval under Part 3A, which are often complex, extensive and multi-stage projects, make the retention of such flexibility appropriate and inevitable." [NAME] at [80]. h."Questions of degree are always involved in determining whether a condition is sufficiently uncertain so as to be outside power." [NAME] at [77]. i."... the finality principle does not apply to a concept plan approval under s 75O": [NAME] per [NAME] at [185] (findings not disturbed on the appeal in [NAME] Planning v Walker [2008] NSWCA 224; (2008) 161 LGERA 423). 46The modifications in Sch 2 Part B of the concept plan or condition B1 of the stage 1 project approval were not uncertain or outside the power to impose. In relation to height, a maximum number of three storeys except for buildings D, E, F, G (stage 1), K, L and M (stage 2) permitted four storeys so that there was no real doubt about what was required to meet the modifications and the condition imposed by the PAC. Height also relates to building articulation and appropriate street presentation. This is clear from the PAC's determination report and the language of modifications and the condition requiring that the fourth storey have a smaller footprint than the third level below to provide articulation to the building form. Density is precisely measured at 60 dwellings per hectare. 47Any change had to comply with the Residential Flat Design Code, an assessment readily capable of achievement by a town planner. The requirement to have a minimum 50 per cent of developable area for deep soil is precise and measurable. The modifications and conditions are clear and precise in terms, are confined in scope and accord with the principles identified in relation to Pt 3A approvals. 48The starting point is not [NAME] , as that case considered Pt 4 of the EPA Act. [NAME] is the appropriate starting point and the Council does not adequately grapple with these principles. The Council contends that the location, height and form of the building envelope are critical to the development and at the heart of what needs to be approved, relying on [NAME] in [NAME] . Part 4 principles should not be applied in Pt 3A as the scale of such projects are greater often complicated multi-stage projects which means that flexibility in conditions is important, see [NAME] at [80]. The facts in [NAME] were quite different, concerning a single two-storey dwelling house and garage. [NAME] principles also apply. The conditions do not provide for separate processes anything like the case in [NAME] . 49The plans approved by the [NAME] are immaterial to this ground which must focus on the wording of the approvals. The Minister did not wish to make further submissions about the additional evidence relied on by [NAME] in its NOMs dated 14 June 2011 and 29 July 2011.

[NAME]'s submissions 50Mison is relied on by the Council as expressing the finality principle applicable to these Pt 3A approvals giving rise to the possibility of a significantly different development which is beyond power. In [NAME] noted at 285 - 286 that there are two categories within the principle that was applied in [NAME] . Firstly, that if a condition significantly alters the development the subject of the application then there is no grant of approval. Secondly, the terms of a condition of consent may lack certainty or finality in the process of environmental assessment necessary to be an "effective consent to the application". In GPT RE Ltd v Belmorgan Property Development Pty Ltd [2008] NSWCA 256; (2008) 72 NSWLR 647 ( [NAME] CJ in Eq agreeing) at [44] - [49] identifies relevant principles in [NAME] , Transport Action Group , Kindimindi and Scott v Wollongong City Council (1992) 75 LGRA 112. [NAME] uncertainty does not give rise to invalidity. A degree of practical flexibility is likely to be necessary. 51Approval can be given under s 75O for a concept plan. [NAME] in [NAME] at [185] held that the finality principle does not apply to concept plan approvals granted under s 75O of the EPA Act as lack of finality is inherent in the notion of a concept plan. This finding should be applied as it is clearly correct. 52In relation to the project approval, Pt 3A makes an important distinction between modifications of a proposal and conditions of approval. Section 75J(4) of the EPA Act provides that the Minister can approve a project with such modifications of the project or on such conditions as the Minister may determine. 53Firstly, the matters complained of at par 18 of the Further Amended Points of Claim, that the conditions imposed by the PAC on the project and concept plan approvals requiring amended plans were either uncertain and/or amounted to a delegation to the [NAME] which was beyond power, are not factually correct because the PAC imposed modifications not conditions. The heading of B1 is "Density and Height Modifications". The text of the clause states that the plans described referred to in the terms of approval shall be "modified" and that amended plans showing compliance with these modifications shall be submitted for approval. 54S econdly, it is questionable whether the finality principle applies to modifications made under approvals granted under Pt 3A of the EPA Act (as opposed to conditions). [NAME] considered conditions only. 55Thirdly, the [NAME] principle has no application under Pt 3A being conceived in relation to the Pt 4 regime which is markedly different to the Pt 3A one. Under Pt 3A there is express power to modify a development approval. The reasoning of [NAME] in [NAME] in relation to concept plan approvals should be more generally applied to Pt 3A modification approvals. Further, subsequent changes to Pt 4 s 80A mean that the principles in [NAME] have less work to do, as recognised in Warehouse Group (Aust) Pty Ltd v Woolworths Ltd [2005] NSWCA 269; (2005) 141 LGERA 376 at [89] per [NAME]. 56Applying [NAME] as explained in Warehouse Group , the terms of the modifications imposed on the project approval give a final and certain development height for the yellow buildings shown in stages 1 and 2 on the drawing in annexure A of [NAME]'s written submissions. The remaining buildings are given "clear criteria" for their final design, being limited to four storeys, the fourth storey to have a lesser footprint than the third level, unit numbers are reduced to maintain a dwelling yield of no more than 60 dwellings per hectare and changes in the built form must comply with the Residential Flat Design Code and have a minimum of 50 per cent of the developable area as deep soil landscaping. The Council's submission that the modifications contemplate changes to the siting and form of the building envelope incorrectly suggests that is open permission to make substantial changes to the development. [ADDRESS] would not construe the modifications to produce that result, per [NAME] at [66] per [NAME]. 57There is sufficient finality under the project approval for the modifications to be given effect without any significant alteration to the approved development. There was no unlawful delegation to the [NAME] in leaving to him the approval of amended plans ensuring these complied with the modifications imposed. The Council's case is based on the terms of condition B1 issued in January 2011 in any event and that cannot be judged based on what the [NAME] approved in March 2011. 58The additional evidence sought and allowed to be relied on referred to in the two NOMs filed after the hearing confirms that additional plans prepared and submitted to the [NAME] by [NAME] have been approved. This overcomes the objection the [NAME] expressed in the letter dated 24 May 2011 that no approval of the earlier plans had been effected. The modifications in the plans approved by the PAC also confirm that these were not within the scope of the PAC's approvals. The grant of modification is also relevant to the exercise of the Court's discretion.

Consideration 59"Project" is defined in s 75A for the purposes of Pt 3A as development that is declared under s 75B to be a project to which this Part applies. Section 75M(2) identifies what an application for a project plan is to contain. The project in this case is stage 1 of a two stage multi-unit residential development consisting of seven multi-storey buildings around the site, including childcare facilities. There is no definition of concept plan in Pt 3A and it is has an inherently [NAME] meaning. The concept plan includes the stage 1 residential development also the subject of the project application, and stage 2 consisting of seven more multi-storey residential buildings identified in plans with numerous related facilities. There is no clear delineation in Pt 3A between what can be the subject of a concept plan and a project. In this case they overlap.

Project approval 60In relation to project approvals, the Council submits and it appears to be accepted by the Minister that the requirement for certainty (also expressed as the principle requiring finality of an administrative decision) can apply in the context of Pt 3A. To what extent is disputed. [NAME] submits that such a principle should not apply to modifications of project approvals under Pt 3A given the greater scale and complexity of such projects and given that approval with modification by the Minister is provided for in s 75J(4). The PAC's project approval refers to modification at condition B1 with the imposition of specified conditions. 61The principle of finality in [NAME] was articulated by the Court of Appeal ([NAME] and [NAME] concurring) in the context of Pt 4 of the EPA Act. As emphasised by the Respondents the development in question was a proposed two-storey dwelling where the consent conditions left the important matter of the height of the building to a council officer for determination. This condition was struck down by the Court of Appeal. The Respondents seek to distinguish the types of development under Pt 4 from those likely to be the subject of Pt 3A, and take [NAME] as the starting point. They further submit [NAME] has no direct application to Pt 3A project approvals, it being a case concerned with Pt 4 of the EPA Act. They rely on [NAME] as examples of where the principle of finality has been considered in the Pt 3A context for project approvals. 62In [NAME] the Court of Appeal held that by leaving an important aspect of the development in question to the determination of a council officer offended the requirement for certainty (that is, the principle of finality) in such a consent and struck down the consent. Section 91 of the EPA Act then provided that development consent could be granted unconditionally or subject to consent conditions. Section 75J(4) is in somewhat different terms, providing that a project may be approved with modifications or on such conditions as the Minister determines. 63The Council also relied on Transport Action Group in the Court of Appeal which concerned s 112(4)(b) which provided for modification of projects seeking approval under Pt 5 of the EPA Act. Projects under Pt 5 are likely to be large and complex, such as government funded infrastructure projects. At issue in Transport Action Group was whether the modification of a highway project under that section required a further environmental impact statement. Mason P ([NAME] and [NAME] concurring) held that modification under s 112(4) required a level of identification and description of the project to qualify as a valid exercise of power. At [116] he did not consider that the principles in [NAME] automatically applied in relation to s 112(4) due to the different statutory content and context compared to s 91 (as it was then). Questions of degree are involved, including in the application of [NAME] in subsequent cases, as cited in Malcolm v Newcastle City Council (1991) 73 LGRA 356, Leichhardt Municipal Council v [NAME] Act 1979 (1992) 77 LGRA 64 and [NAME] . At [123] - [124] Mason P referred to the definition of activity in s 112 as including the carrying out of work and the important difference between Pt 4 and Pt 5. In Pt 5 the decision to modify is not limited by the application lodged with the consent authority. As long as a change is not too radical so as to effect a significant change, it is acceptable. That Pt 5 of the EPA Act includes projects of considerable magnitude and complexity was also referred to by Mason P. It is not confined to a small building job constructed according to a simple plan so that unforeseen problems could be encountered. It is therefore impossible to define an original activity or modification with complete certainty and finality so that some flexibility in decision-making must be allowed. 64The relevant findings in [NAME] concerning the requirement for certainty in relation to conditions imposed under Pt 3A are identified in the Minister's submissions above at par 45(a) - (h), all of which I accept should apply in this case. These include that there is no common law requirement for certainty to validate an exercise of statutory power at [49]. A condition is invalid by virtue of lack of certainty or finality if it falls outside the class of conditions which the statute permits, expressly or impliedly. The construction of the section in the context of the project is necessary, citing [NAME] v Director-[NAME] of National Parks and Wildlife [2001] NSWCA 17; (2001) 130 LGERA 508 at [50]. At issue in [NAME] was whether the particular condition imposed as part of the approval of a coalmine project fell outside the power to impose conditions that s 75J permits. One challenge was that there was uncertainty in giving effect to the condition requiring adjustment of the scale of mining operations to match water supply. This argument was unsuccessful, [NAME] holding that [NAME] ambiguity or uncertainty in the meaning of words does not necessarily lead to invalidity, inter alia. His Honour referred to Transport Action Group at [77] to the effect that questions of degree are always involved in determining whether a condition is sufficiently uncertain as to be outside power. The importance of the retention of practical flexibility, leaving matters of detail for later determination and delegation of supervision of some stage or aspect may be desirable, citing at [78] [NAME], Transport Action Group, [NAME] v [NAME] 3 [COMPANY] [2006] NSWCA 248. Another challenge was that the project approved might be significantly different to that for which approval was sought. Factually this was held not to be demonstrated at [85] - [87]. Legally the challenge that a significantly different project could result required a finding that the condition in question was outside the power conferred in s 75J(4) of the Act. That section allowed modifications of the project as the Minister determined. The condition was found to be a modification of the project within the power conferred in s 75J(4). 65In [NAME] , a judicial review challenge to the approval of a long wall coalmine project under Pt 3A, one of the challenges to the conditions imposed by the Minister was that these lacked finality. [NAME] applied similar reasoning to that in [NAME] at [133] - [135] in determining whether the condition was outside power and whether it was a significantly different project from that applied for. The Council relied on this statement as reflective of the language in [NAME] . 66Kindimindi was a judicial review challenge to the approval of a Pt 4 development application for a large shopping centre on the basis that the consent was uncertain applying the principles in [NAME] , inter alia. As identified in [NAME]'s submissions, [NAME] at [24] identified two categories of overlapping circumstances where there may be no lawful consent, the first being where a condition has the effect of significantly altering the development in respect of the development application and the second being where consent is granted in terms which are uncertain. 67The question is whether the conditions imposed by the PAC in relation to the modified project approval fell outside the statutory framework in Pt 3A because of their uncertain effect in leaving too much discretion to the [NAME] to approve modified plans presented by [NAME] in light of s 75J(4). The Council submitted that there is no relevant difference between the terms "modification" and "condition" in s 75J(4), [NAME] submitted to the contrary. Given that the modification has been imposed by a condition I do not consider there is any relevant distinction between the two under s 75J(4) for the purposes of this matter. It is clear that the PAC has modified the project for which consent was sought and that is enabled by s 75J(4). 68That s 75J(4) provides for the modification of projects by the Minister suggests the argument based on [NAME] that a consent is impermissibly granted for a significantly different development (the first category identified by [NAME] in [NAME] ) faces a far greater hurdle to succeed. That is not the argument made by the Council here however which is that the terms of condition B1 modify the project application in a way which the Council argues is uncertain as a result (the second category identified by [NAME] in [NAME] ). 69The cases reviewed emphasise that the power to modify together with the complexity of projects considered under Pt 3A means the principles in [NAME] developed in relation to Pt 4 will not apply as strictly to Pt 3A, but that a requirement for certainty remains, as recognised in [NAME] . The necessary degree of flexibility will depend on the facts in each case, as recognised in Transport Action Group in the context of Pt 5 and in [NAME] in the context of Pt 3A. As emphasised by [NAME] the project is a large residential development conceived in two stages and far removed from the single dwelling considered in [NAME] . Before resolving the application of the relevant principles in this case to the project approval it is necessary to consider the application of these principles to the concept plan approval.

Concept plan 70The Council submits there is a similar requirement for certainty in relation to the determination of concept plans. The Respondents disagree, relying on [NAME] at first instance ([NAME]) at [185] to that effect. That aspect of his Honour's judgment was not overturned on appeal in [NAME] Planning v Walker [2008] NSWCA 224; (2008) 161 LGERA 423 ( [NAME] ([NAME]). [NAME] did not consider concept plans. The Council submits that such a requirement can and should apply to concept plan approvals because that decision of [NAME] is incorrect and should not be followed as it is not binding on me. Alternatively, given that the concept plan and project approvals were considered together by the [NAME] and the PAC, the same principles should apply to both approvals in this case. 71It is unnecessary to decide if I should follow [NAME]'s findings as the alternative argument of the Council applies. The finding of [NAME] was addressing circumstances where the only application before the Court was for a concept plan approval. The facts in this case are relevantly distinguishable because the stage 1 multi-residential part of the concept plan and the project were identical in the respective applications and the PAC imposed identical conditions of approval in allowing amended plans to be approved in relation to Stage 1. There is no basis on these facts for distinguishing the requirements of the two approvals. The same requirement for certainty applies in this case to the concept plan.

Amendment of plans after the PAC's determination and after the hearing 72Before finally resolving this ground of challenge, the issue arises of whether the history of the plans approved by the [NAME] before and after the hearing are relevant. The plans submitted by [NAME] and approved by the [NAME] in March 2011 did authorise changes beyond the matters referred to in the PAC's approvals and left too much discretion in the [NAME] as identified in the course of the Council's submissions at the hearing. This confirms the Council's argument that the identical conditions (but for the different number of buildings which are permitted to be four-storey) of the two approvals were interpreted by [NAME] and the [NAME] as allowing amendment of plans beyond the express matters identified of the variation of density and the height of some buildings. The [NAME] in the letter to [NAME] dated 24 May 2011 handed up in the course of the hearing advised that no effective approval had been given for the amended plans in March 2011 as these did not conform with the PAC's conditions of approvals. 73While [NAME]'s counsel did not accept at the hearing that this view of the [NAME] was legally correct, after the hearing was completed further amended plans were submitted by [NAME] and approved by the [NAME] on 6 June 2011 presumably because in the [NAME]'s opinion these satisfied the conditions imposed by the PAC in relation to building height and density. New plans were also lodged by [NAME] seeking amendment of the approved project under s 75W(2) in relation to those matters particularly relied on by the Council as falling outside the scope of the PAC's determination (removal of level of basement parking and change of unit lay-outs with the inclusion of studies instead of bedrooms in some units). The amended plans were approved by the PAC on 15 July 2011. These events occurred after the date of the PAC's determination on 18 January 2011 and are strictly not relevant to the Council's argument which focusses on the effect of condition B1 of the project approval/modification 2 of the concept approval. 74The [NAME]'s decision to approve amended plans in March 2011 is not part of the Council's challenge which focusses on the terms of the PAC's determination. The Council has not challenged the decision of the [NAME] to approve the modified plans in March 2011 as being a decision outside the scope of the delegation by the PAC. Therefore the whole history of plan approvals before and after the hearing, including withdrawal of the [NAME]'s consent during the hearing and subsequent approval of amended plans by the [NAME] and the approval by the PAC of an application for modification of the PAC's approval under s 75W also has no weight. If able to be considered as relevant to confirm a foresight, that history as a whole confirms that the PAC's determination did allow modifications in amended plans to be approved by the [NAME] which were certain in effect, being confined to changes in building height and density only. The s 75W modification application approved relates to amendments beyond those issues such as floor plan changes and carparking changes which were criticised in the Council's case (par 41) as beyond the scope of the PAC's original determination.

Conclusion 75Meriton sought approval for residential development at a density of 75 dwellings per hectare and building heights of variously three, four and five storeys. The PAC's approvals modify the project in allowing [NAME] to lodge amended plans with the [NAME] for approval in relation to specified density and height changes for four (D, E, F, G) of seven buildings in stage 1 which are limited to a maximum yield of 60 dwellings per hectare in condition B1(a) and for an additional three buildings in stage 2 in relation to the concept plan. This is to be achieved as specified in condition B2(b)(i) - (iii) project approval /modification 2(2) concept plan approval. Any fourth storey must have less area than any third storey below, compliance with the Residential Flat Design Code is required and a minimum area of 50 per cent of deep soil must be maintained. The project and concept plan as modified by the PAC is for a lesser density and permits no five-storey buildings and a limited number of four storey buildings. 76The discretion conferred on the [NAME] (and [NAME]) by the PAC's conditions is confined. The PAC's conditions specify limits on the height of development and buildings which can be four storeys with restrictions as to their form, inter alia. These provisions limit how the discretion to approve plans is to be exercised by the [NAME]. Matters the Council relied on were that the building envelope on the land is not specified and the wording of the condition allows different floor plans and numbers of rooms provided the requirements in condition B1 of the project approval/modification 2 of the concept approval are met. The latter argument in relation to floor plan and numbers of rooms is not maintainable as the wording of the conditions does not specify modifications of this nature. The limits on the modification of plans imposed by the PAC did have the effect of limiting changes in the building envelopes. 77I consider that there is sufficient certainty in the conditions of approvals for the project and concept plan for stage 1 issued by the PAC that the modifications are within s 75J(4) taking into account the need to allow flexibility in relation to Pt 3A matters. The modifications are in accordance with specified criteria which limit the discretion of the [NAME] to approve modified plans. The answer to the challenge posed by the Council of whether the approvals allow for such a significant variation by the [NAME] of what is proposed in relation to siting of buildings and their form that the conditions lack certainty and are not final is not established. The Council is unsuccessful on this ground.

Ground of challenge - No probative evidence before the PAC to support decision

Council's submissions 78The PAC decision to grant concept plan approval and project approval was made without any probative evidence to support it. Reliance was placed on the [NAME] in purporting to impose conditions in relation to density of development on the site. The [NAME] provides no evidentiary basis for the PAC's determination and imposition of the conditions in the approvals. It is well settled that an administrative decision can be invalidated where there is no probative evidence to support it: see Bruce v Cole (1998) 45 NSWLR 163 at 188 - 189; [COMPANY] v [COMPANY] ( [NAME] ) [2006] NSWCA 276 at [52] - [53]; compare Administrative Decisions (Judicial Review) Act 1977 (Cth) s 5(3). See also Ormwave Pty Ltd v Smith [2007] NSWCA 210 at [14] - [15]. 79The PAC's determination to approve the concept plan and the project rejected the recommendation of 25 dwellings per hectare in the Council's [NAME]. Nor did it adopt the [NAME] report's recommendation of 81 dwellings per hectare. It identified the need for a strategic study of the Warriewood Valley and nevertheless determined to take its lead from the [NAME] which sets out a long-term framework or vision for the greater Sydney area. 80The [NAME] does not provide any probative support at all for the PAC decision. It is a high-level document not intended to provide a basis for giving [NAME] approval to individual developments. This was the view expressed in a departmental briefing note dated 5 April 2011 in relation to Action D2.1 in the [NAME]. 81The PAC purported to approve medium rise development, not low rise medium density housing described in the [NAME] and encouraged around small local centres under that strategy. Buildings with four storeys are medium rise not low rise. The combined approvals allow for seven of the sixteen buildings on site to be four storeys high. The density chosen by the PAC of 60 dwellings per hectare is the maximum density permitted under the [NAME]. When combined with building heights of four storeys, the [NAME] is not evidence that justified the PAC's decision. 82The Minister and [NAME] assert in their points of defence that there was other evidence before the PAC which would justify the decision. The only material from which the PAC appears to draw guidance and support is the [NAME] which even then encourages a materially less dense and less high outcome than the PAC determined.

Minister's submissions 83This ground has no foundation given the PAC's determination report. The Minister does not dispute that the [NAME] was considered in the assessment of density issues. Indeed, it is clear from the PAC's determination report that the strategy was prominent in the PAC's consideration of the project and concept plan applications. 84However, in order properly to assess the Council's no evidence ground, the significance of the [NAME], the context in which it was developed, and its relationship to the draft [NAME] must be considered. The [NAME] aims to provide an integrated long-term [NAME] framework based on various strategic directions and key policy settings. It aims to integrate land use and transport [NAME] and followed extensive consultation. The Minister by his delegate PAC also referred to the draft [NAME] which is similar in style and approach to the [NAME] but focusses on the north eastern suburbs of Sydney including Pittwater. [NAME] is identified as an intermediate step in translating the [NAME] to a local level. One of the aims of subregional [NAME] is to identify the future role of centres and corridors, as well as towns, villages and neighbourhood centres in relation to the overall structure of the metropolitan area. The implementation of the [NAME] and draft [NAME] will have statutory force under s 117 directions by the Minister. 85The draft [NAME] was placed on public exhibition for 60 days to enable community feedback. It calls for 4,600 new dwellings in the Pittwater area. The PAC concluded that housing requirements had increased since its preparation and it was likely that more housing would be required in the [NAME] area. Both documents are high level [NAME] policies prepared by the NSW Government to guide land use and integrated transport [NAME] and guide [NAME] at the local level through LEPs. [NAME] required [NAME] to address the provisions of the draft [NAME] in its [NAME]. 86Further there was extensive evidence before the PAC including [NAME]'s PPR, the [NAME]'s report, the Department's supplementary report dated 10 December 2010 (recommending 75 dwellings per hectare), the [NAME] report (also recommending 75 dwellings per hectare), the [NAME] traffic report as well as the draft [NAME] and the [NAME]. Each document contained strategic justification for the applications before the PAC and considered appropriate density for the site. 87The PAC's decision should not be read keenly with an eye attuned to the perception of error ( [NAME] Immigration and Ethnic Affairs v Wu Shang Liang [1996] HCA 6; (1996) 185 CLR 259 at 291; Walsh v Parramatta City Council [2007] NSWLEC 255; (2007) 161 LGERA 118 per [NAME] at [67]; and JPR Legal Pty Ltd v Marrickville Council [2009] NSWLEC 156 per [NAME] at [40] ) so that there is no basis in the language of the PAC's determination report for finding that the PAC rejected all of these studies. While the PAC took its lead from the [NAME] in relation to the development density of 60 dwellings per hectare, the other documents before the PAC also provided justification for the increased density of dwellings per hectare which were considered to be acceptable. Only the LEP and the [NAME] recommended lesser density for the site. The documents supporting greater density were before the PAC and are evidence capable of supporting the PAC's determination. An inquiry into the sufficiency of evidence is not legitimate in judicial review proceedings. 88The Departmental briefing note is dated 5 April 2011 which is after the event and cannot be relevant. In any event it does not state that the [NAME] was not permitted to refer to the [NAME], which builds on the earlier Metropolitan Strategy 2005. 89The High Court has advocated caution in assessing no evidence claims since it confronts the spectre of impermissibly trespassing upon the merits of administrative decision-making: Australian Broadcasting Tribunal v Bond [1990] HCA 33; (1990) 170 CLR 321 per [NAME] at 341. An enquiry into the sufficiency of evidence is not legitimate in judicial review proceedings: [NAME] at 356 - 357. The Courts' role extends only to ensuring that the conclusion reached has some evidentiary basis. It does not extend to an assessment of whether or not it was a logical or correct conclusion: [NAME] at 355 - 356.

[NAME]'s submissions 90A valid decision cannot be based on no evidence in the sense of there being a complete absence of evidence per [NAME] v [NAME] but that is not the fact in this case. The [NAME] does not forbid its use in Pt 3A assessments. While framed at a high level of abstraction and intended to be used to inform the making of strategic and local plans, use of the [NAME] was permissible in Terrace Tower Holdings Pty Ltd v Sutherland Shire Council [2003] NSWCA 289; (2003) 129 LGERA 195 at [77],[81] per Mason P and Stockland Development Pty Ltd v Manly Council [2004] NSWLEC 472; (2004) 136 LGERA 254 at [33], [91]-[92] per McClellan J. Its use was also reasonable. 91It is a [NAME] principle of the Court that the role of non-statutory plans is not one of subservience to local instruments and that they can and should be used in the process of environmental assessment of applications under Pt 4 of the EPA Act: Direct Factory Outlets Homebush v Strathfield Municipal Council [2006] NSWLEC 318. There is no reason to exclude such plans from an assessment under Pt 3A of the EPA Act. In considering s 75J of the EPA Act [NAME] in [COMPANY] v [NAME] [2004] NSWLEC 396 at held at [104] that a decision will only be vitiated if the decision-maker fails to consider matters it was bound to consider as determined by statute per [NAME]. 92The PAC properly took account of the ability of the site to hold a significantly higher residential density than the Council's local controls would permit under Pt 4 of the EPA Act and therefore varied the control to approve the project. Further, the PAC did not rely exclusively on the [NAME] in arriving at its conclusions, contrary to the Council's submissions (but there is no problem if it did rely on it exclusively in any event). It had before it a range of opinions as to the appropriate density including from the Department which recommended 75 dwellings per hectare. The PAC was entitled to modify the density and height of buildings sought by [NAME], as it did. It did so within the range, albeit at the end of the range. The PAC is an expert panel and can determine what is the appropriate height and density. 93The executive summary expressly notes that the PAC only took its lead from the [NAME], but ultimately decided to determine the applications based upon the merits and what the PAC considered to be appropriate standards. Given that the PAC is a specialist body (see Sch 3 cl 2(3) of the EPA Act) the members were entitled to bring their own experience and expertise in their fields to bear in formulating "appropriate standards" to determine the application on its merits. 94The Departmental view after the event that the [NAME] was not intended to be used in that fashion is immaterial as there is no suggestion this view was made known to the PAC. When the memorandum is viewed as a whole it recognises that Action D2.1 does not preclude residential flat buildings in smaller local centres. In any event there was a great deal of additional material before the PAC enabling it to determine the project and concept plan on their merits. [ADDRESS] is entitled to assume that the PAC had constructive knowledge of all the material before it in reaching its decision per Schroders Australia Property Management Ltd v Shoalhaven City Council [1999] NSWLEC 251; (1999) 110 LGERA 130 at 133 ([NAME]).

Consideration 95The principles underpinning the no (probative) evidence ground as found in [NAME] v [NAME] per [NAME] at 188 - 189 and as discussed in [NAME] and [NAME], Judicial Review of Administrative Action , 4th ed (2009) [NAME] at [4.370] - [4.380] emphasise that the ground is narrow. The discussion in [NAME] and [NAME] commences with [NAME] where [NAME] stated that provided there is some basis for an inference to be drawn even if that appears to arise from illogical reasoning there is no error of law. There must be no probative evidence before the decision-maker to support findings of fact made in order to succeed on this ground. 96This ground of legal challenge was raised in Marrickville Metro Shopping Centre Pty Ltd v Marrickville Council [2010] NSWCA 145; (2010) 174 LGERA 67 , considered by [NAME] at [95] - [98]. That case concerned the discretionary decision of a council to impose a rating category which applied to only one premises in the relevant local government area. [NAME] identified that the no evidence ground in [NAME] v [NAME] was made in the context of an alleged failure of the Conduct Division of the Judicial Commission of NSW in that it was required to make a finding of fact that a judicial officer's incapacity was continuing at the time of the report. [NAME] at [97] identified that where an exercise of statutory power by a body such as a council is dependent on the existence of a fact or holding of a particular opinion, the absence of evidence to support that finding of fact can vitiate a decision. Under the statutory regime, his Honour was considering the rating provisions of the Local Government Act 1993. The relevant rating decision did not have to be made according to any statutory criteria which had to be satisfied before exercising the power suggesting a finding of no evidence would not be made in that case. Those observations are also important in the context of the discretion exercised by the PAC on behalf of the Minister under Pt 3A which does not require any finding of fact or satisfaction of any matter before a decision to approve a particular project or concept plan is made. The PAC has a [NAME] discretion under Pt 3A in weighing up the [NAME] merits of the applications before it, provided this is exercised within the scope and objects of the EPA Act. 97The Council submits the PAC relied on the [NAME] in its determination to support its conclusion about the appropriate density. Consequently, the determination lacked supportive evidence because the [NAME] is not an instrument intended to provide controls for any individual sites including buffer area 3 at Warriewood Valley. The Respondents submit that the PAC did not rely solely on the [NAME] as can be seen in the determination which refers to matters raised in meetings with the Department, the [NAME], and the various and extensive [NAME] reports and the Council's [NAME] instruments. 98The PAC does not have to provide a report of its reasons under Pt 3A and is not exercising judicial or quasi-judicial functions with the attendant requirement to give closely analysed reasons. The Minister's submission on the importance of reviewing such reasons without an eye attuned to the perception of error applies. Reliance was placed on the [NAME] when the PAC determination is reviewed. This refers to the PAC taking its lead from the [NAME]. The only document before the PAC which referred to 60 dwellings per hectare was the [NAME]. The Strategy was released on 16 December 2010, not long before the PAC's determination on 18 January 2011. The concept plan and project were referred to PAC on 15 November 2010. 99As highlighted and reviewed extensively in the Respondent's submissions, there was also a great deal of other material before the PAC and it was extensively informed of the issues of density and height of buildings, inter alia, by all parties. The Department and [NAME] were seeking a yield of 75 dwellings per hectare and a mix of three, four and five storey buildings as identified in [NAME]'s PPR, the [NAME]'s report and the Department's supplementary report to the PAC. [NAME]'s [NAME] dated March 2010 had assessed and supported 81 dwellings per hectare. The [NAME] report prepared for the Department recommended 81 dwellings per hectare in the buffer areas. The most recent Council strategic report (the [NAME]) recommended 25 dwellings per hectare. Section 4 of the PAC's determination refers to the Department's supplementary report provided at the request of the PAC in relation to urban development in the Warriewood Valley and the [NAME]. 100The parts of the draft [NAME] referred to by the Minister's counsel identified the number of dwellings required in the [NAME] area as a whole for the next twenty-five years. The draft [NAME] released in July 2007 was created in response to the Metropolitan Strategy 2005. That document was also not intended to provide site-specific densities. Its implementation was intended through s 117 directions. The same observation as can be made in relation to the [NAME] applies to this subregional strategy, namely that was not an irrelevant consideration for the PAC's determination. 101Here the PAC was exercising a [NAME] discretion in the context of Pt 3A of the EPA Act. That the effect of the PAC's decision was, as submitted by the Council, to almost triple the density for the site above the density that has applied elsewhere in this area to date was not outside the [NAME] discretion it has under Pt 3A. While it is not accurate to describe the figures in the [NAME] as controls because the intent and nature of that document is to provide [NAME] level strategic advice which will be implemented at a site specific level through LEPs responding to s 117 directions issued to the Minister, it is not an irrelevant document to consider in the Pt 3A framework. 102Meriton's counsel relied on [NAME] which considered s 75J(2) concerning the decision of a Minister whether or not to approve a project. That subsection states the considerations the Minister must take into account, which include relevantly for this matter the [NAME]'s report on a project. Her Honour stated at [104] that there are matters which the decision-maker is bound to take into account or not take into account and the further category of matters where there is a discretion whether or not to consider the matter. This authority supports the argument I have accepted that the PAC could take into account any matter not expressly or impliedly forbidden to be taken into account under the statutory scheme which is otherwise within the objectives of the EPA Act and the Pt 3A scheme. 103Support for this conclusion arises from two cases referred to by the Respondents where broader level [NAME] documents were taken into account as part of a merit assessment process. In [COMPANY] the Court of Appeal considered whether in a merit review appeal the trial judge was in error in taking into account various policy documents some with legal status under the EPA Act such as draft SEPPs, and some [NAME] level strategic documents (set out at [71]) without legal status. [ADDRESS] of Appeal held there was no error in the consideration of the draft SEPPs in the assessment of the project in the Court, as matters that could clearly be taken into account under (then) s 79C(1)(a)(ii). At [81] Mason P stated: In any event, matters relevant to the public interest touching a particular application are not confined to those appearing in published environmental [NAME] instruments, draft or final. Obviously such instruments carry great and at times determinative weight, but they are not the only source of information concerning the public interest in [NAME] matters. The process of making such instruments is described by [NAME] in [COMPANY] v [NAME] Affairs and [NAME] (1997) 95 LGERA 33 at 42-44. Nothing in the [NAME] Act stipulates that environmental [NAME] instruments are the only means of discerning [NAME] policies or the "public interest". For one thing, the government is not the only source of wisdom in this area. A consent authority may range widely in the search for material as to the public interest (see generally Shoalhaven City Council v Lovell (1996) 136 FLR 58 at 63; [COMPANY] v [NAME] (2001) 119 LGERA 231 at 235). 104In Stockland , a merit review appeal against a refusal of a development application for a large shopping centre under the EPA Act by a local council, McClellan J had to consider what Council instruments and policy documents he would take into account under (then) s 79C(1)(a)(i)(iii), (b),(c), (e). The council was relying on development control plans and urban design documents. At [86] - [87] his Honour considered the role of development control plans. At [88] he recognised that there are many cases where a council adopts statements of policy for its area not included in such plans. He referred approvingly to Mason P's statements in [COMPANY] about the public interest being discernible beyond environmental [NAME] instruments. He went on to consider at [91] and beyond that weight can be given to a detailed policy depending on a number of matters including the level of public consultation and research undertaken, the time the policy is in force, the extent of departure from it, its compatibility with other environmental [NAME] instruments and development control plans, inter alia. 105Both cases were considering the merit review context in relation to development consents granted under Pt 4 of the EPA Act and emphasise that a wider range of documents than those which are required to be taken into account under the EPA Act can be considered. Part 3A provides a less constrained decision-making framework when contrasted with Pt 4. Such cases establish that documents which are not legal instruments required to be considered under the EPA Act can inform decision-makers. Under s 75J(3) and s 75O(3) the Minister and therefore the PAC is not bound by the provisions of any environmental [NAME] instrument but may take these into account. No compulsory [NAME] instrument specifying relevant standards and controls as would apply under Pt 4 applies under Pt 3A. The PAC did not have to apply the provisions of the LEP, DCP 21 or the [NAME]. Here the PAC has relied in part on a [NAME] level strategic [NAME] document released immediately before the PAC's determination to identify a site-specific standard. 106That leads to the consideration of PAC's role as an expert panel under Pt 3A of the EPA Act. The members of the PAC are appointed as an expert panel (Sch 3 cl 2(3) identifies the expertise one of which each panel member must have). The Respondents, particularly [NAME], submit that the panel is expected and should apply its [NAME] expertise to the determinations it must make. The PAC considered that a strategic study of all undeveloped sites in the Warriewood Valley was required jointly between the Council and the Department. The PAC considered it was able to assess the "proposal on its merits and in the context of what it considers to be appropriate standards for the future of the Valley." The reasons it identified include the need to increase housing stock in metropolitan Sydney and in each subregion to meet the housing demand generated by a growing population and changing household requirements. The Council submits that the PAC must exercise its powers on the basis of probative evidence which is a correct submission but the scope of that evidence is informed by the statutory context in Pt 3A. That allows the PAC wide discretion in carrying out its functions when determining an application on its merits. 107The Council is unsuccessful on this ground. This ground overlaps with the fourth ground of challenge that the PAC's decision was unreasonable in the Associated Provincial Picture Houses Ltd v Wednesbury Corporation [1948] 1 KB 223; [1947] 2 All ER 680 sense.

Ground of challenge - Failure to take into account a mandatory relevant consideration (the LEP and site isolation) 108The DGEAR are set out in full at par 9 above. [NAME] 1 requires identification of relevant environmental [NAME] instruments to be addressed as listed in appendix A which includes the [NAME] 1997. [NAME] 4 is headed "Land uses and density" specifying the range of land uses proposed and consistency with the objectives of "Urban Purposes - Mixed Residential" zone and provide justification for the proposed dwelling yield and floor space. [NAME]'s [NAME] prepared after the receipt of [NAME] referred to the LEP at section 5.13. The [NAME]'s report referred to the LEP in section 4.3, "Statutory context", and in appendix 6 without referring specifically to the density provisions in the LEP. 109In relation to isolated sites, [NAME] 5 stated that the proposal should seek to amalgamate with the adjacent properties at 5 and [ADDRESS]. The [NAME] was to include details outlining negotiations with the owners of that property. If amalgamation was not possible the [NAME] was to address the development potential of those lots. [NAME]'s [NAME] included a section on isolated sites (section 7.4). Correspondence with the owners of 5 and [ADDRESS] sent in August 2008 and February 2010 was attached to the [NAME] (appendix Z). In the later letters [NAME] wrote to confirm that the recipient did not wish to be included in the residential development of buffer area 3. One owner responded in February 2010 that they wanted to be a part of any future [NAME] and zoning changes to the land. The letter from the other owner dated March 2010 stated her intention to develop the property in the future and supported an increase in the dwelling density for buffer area 3. The [NAME] included a concept plan identifying the development potential of the neighbouring properties (fig 31). In the [NAME]'s report site isolation was referred to in section 6.6 which stated that the proposal does not include the two existing residential properties at 5 and [ADDRESS]. The preliminary building design plan for the two properties to demonstrate development similar in height, scale and density to that proposed on the subject site could be accommodated on a consolidated site in the future was referred to.

Council's submissions 110The DGEAR 4 requires demonstrated consistency with the objectives of the 2(f) (Urban Purposes - Mixed Residential) zone in the LEP, DGEAR 1 requires justification for non-compliance with the LEP, and DGEAR 5 requires [NAME] to seek to amalgamate with neighbouring landholders (isolated sites). 111In approving the concept plan and the project, the PAC failed to take into account the existing density permitted on the site under the LEP. The objectives of the 2(f) zone in cl 30B(2) of the LEP are a [NAME] mandatory relevant consideration for the Council. The objectives of that zone include the identification of land suitable for residential development which will be provided with adequate physical and social infrastructure in accordance with a [NAME] strategy for the area. The [NAME] strategies were the [NAME] and the [NAME] 1997. The latter was replaced by the [NAME]. 112The [NAME]'s report which was before the PAC makes no attempt to demonstrate consistency with those objectives. The table at TB vol 3 tab 12 directs the reader to section 7.3 but that does not address these DGEAR. The third paragraph in section 7.3 directs the reader to section 6 but that section also does not purport to demonstrate consistency with the objectives of the zone. The PPR makes no reference to these objectives. The [NAME]'s report states very little except in section 4.2 where there is a statement directed to permissibility of the childcare centre, pool and gym which omits the critical words "in accordance with a [NAME] strategy for the area". 113Further, in relation to [NAME] 1 (justification for non-compliance with the LEP) the [NAME]'s report seeks to provide justification for the height and density non-compliance but does not. Section 4 "Statutory Context" refers to appendix 6. Appendix 6 mentions the LEP in one sentence at TB vol 1 p 541, which refers back to sections 4 and 6. Section 4 takes the matter no further. Section 6 does not mention the LEP. The PAC rejects the justifications advanced by [NAME] and the Department, and relies on the [NAME]. 114Further [NAME] 5 required the provision of certain information in relation to amalgamation of isolated sites. As can be seen from the letters sent to the landowners in question [NAME] made very little effort to comply with this requirement. The information was not considered in section 6.6.1 of the [NAME]'s report prepared under s 75I. It is not mentioned in the PPR prepared for [NAME]. There is no mention in the PAC's determination of this requirement and was not a matter before PAC based on the [NAME]. 115The DGEAR are a mandatory relevant consideration and have an important role in the Pt 3A scheme. Under s 75F(2) the [NAME] is to prepare them and notify [NAME] of them, s 75F(3). [NAME] may require [NAME] to prepare an [NAME], s 75F(5). A power is conferred on the [NAME] to require a revised [NAME] to be submitted if he or she is of the view that the [NAME] does not adequately address the requirements in s 75H(2). The [NAME] is obliged to include a statement of compliance with [NAME] under this Div in relation to the project (s 75I(2)(g)) and the Minister is obliged to consider the [NAME]'s report and the statement relating to compliance with DGEAR in it before approving or rejecting the application, s 75J(2)(a). 116The [NAME]'s consideration of whether an [NAME] adequately addresses [NAME] is a reviewable decision per [NAME] v [NAME] [2006] NSWLEC 720; (2006) 152 LGERA 258 at [75]. The Minister's exercise of power under s 75J(2) is conditioned on his or her consideration of the [NAME]'s report, including the statement relating to compliance with [NAME] v [NAME] [2010] NSWLEC 129; (2010) 176 LGERA 395 at [68]. 117It is common ground that one issue before the Court is whether it is to be inferred that the PAC gave "legally sufficient consideration" ( [NAME] at [13]) to the s 75J(2)(a) and the s 75O(2)(a) "statement relating to compliance with environmental assessment requirements". The Council submits, the Respondents deny, that a further issue is whether the Court can go behind the statement of compliance in the [NAME]'s report, in order to determine whether it is a valid statement for the purposes of s 75J(2)(a) and s 75O(2)(a). 118There is nothing in [NAME] v [NAME] [2007] NSWLEC 490; (2007) 158 LGERA 349 which is inconsistent with the Council's arguments. The challenge [NAME] was considering was a technical challenge as a change in the law required that the words stating that there was compliance appear in the report and they did not. It was conceded that had a single additional sentence been included s 75O(2)(a) would have been met. Her Honour considered there was no useful purpose served by the appearance of such a statement and it did not represent a critical omission which deprived the Minister of an opportunity to consider that statement as required by s 75O(2)(a).

Minister's submissions 119Mason CJ in [NAME] at 44 - 45 identifies that a matter will be a mandatory relevant consideration if so identified in the statute, whether expressly or impliedly by reference to the subject matter, scope and purpose of the statute. See also [NAME] per [NAME] at 104. In [NAME] (citing the decision of the Court of Appeal in [NAME] ([NAME])) observed that to succeed on the basis of failure to have regard to a relevant consideration, "the statute must expressly or impliedly oblige the decision-maker to enquire and consider the subject matter at the level of particularity involved in the applicant's submissions." See also [NAME] v [NAME] [2006] NSWLEC 725; (2006) 151 LGERA 229 at [38] - [41] per [NAME] and [NAME] v Director-[NAME] of the Department of Environment and Conservation [2007] NSWLEC 722; (2007) 159 LGERA 172 at [77] and [105] per [NAME]. 120The density controls in the LEP are not a mandatory relevant consideration in relation to decisions under s 75J and 75O of the EPA Act. It can, not must, be considered under s 75J(3) and 75O(3) and the Council's submissions are directly contrary to these sections. Under s 75J(3) and s 75O(3) the Minister has discretion as to whether an environmental [NAME] instrument is taken into account. The fact that the LEP was referred to in [NAME] does not elevate it to a mandatory relevant consideration. 121Further, the Council submits that the Minister's exercise of power under s 75J(2), read with s 75I(2)(g) miscarried for want of compliance with the requirement that the Minister must consider the statement relating to compliance with environmental assessment requirements and be satisfied that the statement has not been made on a false premise. Section 75J(2)(g) does not impose any obligation on the [NAME] to form an opinion about the matter nominated in that subsection: [NAME] per [NAME] at [95] and [96]. 122The PAC had the [NAME]'s report before it and is presumed to have read it. The [NAME]'s consideration of whether an [NAME] adequately addresses [NAME] is not a reviewable decision and cannot extend to a review of whether the statement of compliance has been made on a "false premise". That is contrary to [NAME] . The statement relating to compliance is relevantly identical to that in [NAME] per [NAME] at [60]. 123It also ignores the fact that while the adequacy of an [NAME] may be reviewable, in this case the assessment of the project and concept plan is much further advanced. The adequacy of the [NAME] having regard to all of the documents which were before the PAC at the time of its determination is the relevant enquiry. Under s 75J(2)(c) of the EPA Act, the Minister must for example consider any findings or recommendations of the PAC following a review in respect of the project. In the instant case, because the PAC was delegated approval making powers, it was able to inform its decision via its own findings from such matters as the [NAME] report, the [NAME] traffic report, the [NAME] and the draft [NAME]. 124The Council is correct that the [NAME]'s report is a mandatory relevant consideration for the Minister (here PAC) (as set out in s 75J(2)(a)), but it cannot follow that each of the 18 DGEAR is a mandatory relevant consideration. They are merely relevant considerations which cannot be elevated to mandatory status. Such a submission, with respect, ignores the way in which Pt 3A was intended to operate and in particular, the purpose of s 75J(2) as construed in [NAME] . 125Ultimately, this ground involves an invitation to the Court to assess the weight given by the Minister, by his delegate the PAC, to the LEP. Such a review is not permitted. [ADDRESS] should reject this ground of challenge. In any event the density controls in the LEP were considered in section 4.3 and appendices 5 and 6 of the [NAME]'s report and section 6.1 of the [NAME]. 126In relation to isolated sites, the Council must make good that this was a mandatory relevant consideration and that the error was so material that the Court's intervention is warranted (for example [NAME] per [NAME] at [31]; Parramatta City Council v Hale (1982) 47 LGRA 319 at 335 per Street CJ and [NAME] at [66] per [NAME] (with whom [NAME] and [NAME] agreed)). The Council has made good neither factual proposition.

[NAME]'s submissions 127The PAC must consider all relevant matters required by the EPA Act and must disregard those forbidden by the Act. There may be a range of other considerations that may be taken into account by the PAC at its own discretion: the Court of Appeal in [NAME] ([NAME]) and [NAME] at 41. In relation to concept plan approvals s 75O(2) states what must be considered and for project approvals s 75J(2) so states. These matters are not mandatory in relation to an approval. Under s 75X(5) the only matter identified as a mandatory requirement is a requirement that an [NAME] is made publicly available under s 75H.

Provisions of the LEP 128Non-compliance with s 75O or s 75J is not alleged. Rather the Council alleges a failure by the PAC to consider the density specified for the site under the LEP as required by [NAME] 1 and 4. The LEP density controls are not a mandatory matter to consider under Pt 3A as identified in s 75O(3) and s 75J(3). The ground is further pursued on the basis that [NAME]'s [NAME] did not satisfy [NAME] on this topic and the conclusion that [NAME] were complied with is not reviewable. 129In any event, as a matter of fact the Minister through the PAC expressly considered the density controls in the LEP when the concept plan approval and the project approval were given. These were drawn to the attention of the PAC on numerous occasions including in [NAME]'s submissions to the PAC. 130The Council cites [NAME] at [68] in support but [NAME] does not stand for the proposition for which it is cited, namely that the Minister's power under s 75J(2) is conditioned on his or her consideration of the [NAME]'s report. His Honour's finding that the statement relating to compliance is a jurisdictional fact should not be read as intending to mean that the Court can review its correctness. To interpret it otherwise will also place it in conflict with [NAME] which reasoning should be applied. [NAME] in that case held that Pt 3A and s 75I(2)(g) does not require that there be certification of compliance with [NAME] at [93]. 131Whether the [NAME] was sufficient to address [NAME] is a matter for the [NAME] to consider and the Council's submissions about inadequacy are not relevant. There was in any event justification for greater density to be imposed identified in [NAME]'s [NAME]. 132The LEP is not a starting point from which [NAME] had to justify departure to the Minister and nor is the Court to consider itself that departure is justified. There is no requirement that the Minister consider these controls so that it cannot be correct that the Court can consider them to see if there has been compliance. [NAME]'s entire [NAME] was directed to demonstrating to the PAC that the environmental constraints of the site were not sufficient to justify the low residential density supported by the Council's controls. The [NAME] referred specifically to density and explains why consent for approximately 600 dwellings is sought taking into account various considerations relevant to the site. The draft [NAME] is referred to, the existence of public transport and the Council's controls are specifically referred to. Clause 30B of the LEP is referred to which includes the objective of identifying land within the Warriewood Valley urban release area suitable for urban development to be provided with adequate physical and social infrastructure in accordance with the [NAME] strategy for the area and [NAME] seeks to do that in the [NAME]. 133Further the PAC was well aware of the [NAME] history of the Warriewood Valley, that the Council had granted approval for 140 lots involving 135 2-storey townhouse developments on the site, the [NAME] report demonstrated that the land could sustain a significantly higher density than was provided for under the LEP and the physical layout of the site and placement in the surrounds. The approvals granted clearly took into account the existing controls as the project and concept plan were modified to reduce the density to medium density on the site with some four-storey buildings to the centre of the site as the natural ground level sloped down.

Isolated sites 134In relation to isolated sites, there was material included in the [NAME]'s report on this topic. The [NAME] executed a statement of compliance under s 75I(2)(g) and that is an answer to the matter pleaded. [NAME]'s [NAME] addressed the topic advising that [NAME] had contacted the owners of 5 and [ADDRESS] to see if they wished to be involved. The correspondence was attached to the [NAME] and a concept plan addressing the development potential of these sites was included. Even if [NAME] concedes that more might have been done to negotiate with one owner, as one was clearly not interested there was no utility in pursuing amalgamation where at least one party was not interested. Nothing more was required to be done in the circumstances. 135The Council submits that [NAME] imposed an obligation to provide a detailed account of bona fide negotiations with adjacent property owners and the material provided was not sufficient to discharge that obligation so that the PAC did not consider the matter at all. No such obligation was imposed. [NAME] specified that the project must seek to amalgamate adjacent properties into the development site and address their development potential if not included. [NAME] was to negotiate with owners of affected properties. The Council acknowledges that one owner did not wish to amalgamate but in fact neither owner wished to do so. In any event there was no obligation on [NAME] to commence active negotiation in order to acquire the adjoining lands. The letters sent indicate a sufficient refusal by neighbouring landowners to amalgamate to conclude that the [NAME] had sought to amalgamate but this was not possible. [NAME] then demonstrated that the development potential would not be affected by providing drawings showing the connection of internal roads from the project to these sites.

Consideration 136The Council focusses on three requirements of [NAME] (1, 4 and 5) which it submits were mandatory relevant considerations not adequately considered in the [NAME]'s report and therefore not considered (or not properly considered) by the PAC in its determination. The Council bears the onus of establishing this ground of challenge. The Respondents submit that individual requirements in [NAME] cannot amount to mandatory relevant considerations, adopting the reasoning of the Court of Appeal in [NAME] ([NAME]), and in any event the PAC considered these matters when it determined the approvals before it . Further the Minister submits that the relevant focus under this ground is the PAC's determination as a whole, not restricted to the consideration of the [NAME]'s report only. This latter submission is significant in light of the facts in this case and is the appropriate basis for consideration of this ground. Consequently, it will not be necessary to determine every issue raised by the Council's submissions which focussed on the [NAME]'s report. 137The identification of principles applicable to the ground of failure to take into account a mandatory relevant consideration generally commence with [NAME] , referred to by all parties. [NAME] states that whether a matter is a mandatory relevant consideration is determined by reference to the subject matter, scope and purpose of the particular statute and can be express or implied. There has been much judicial consideration of this ground, as identified in the Minister's submissions (written submissions at par 77) which correctly identify that it is to be borne in mind that "epithets such as 'proper, genuine and realistic' consideration... risk an assessment of the nature of the consideration which will encourage a slide into impermissible merit review": [NAME] ([NAME]) per [NAME] ([NAME] agreeing) at [35]; Azriel v NSW Land and Housing Corporation [2006] NSWCA 372 at [51] per [NAME] ([NAME] agreeing); [NAME] at 297 at [79] per [NAME] ([NAME] and [NAME] agreeing); Belmorgan Property Development Pty Limited v GPT RE Ltd [2007] NSWCA 171; (2007) 153 LGERA 450 at [76] per [NAME] ([NAME] agreeing); Notaras v Waverley Council [2007] NSWCA 33; (2007) 161 LGERA 230 at [118] - [120] per [NAME] (Mason P and [NAME] agreeing); and [NAME] v [NAME] at 186E per [NAME] ([NAME] agreeing). A s cited by [NAME] in [COMPANY] v Director-[NAME] of the NSW Department of [NAME] (No 2 ) [2011] NSWLEC 83 at [100], t he High Court has more recently applied again the phrasing of "proper, genuine and realistic consideration" in [NAME] Immigration and Citizenship v SZJSS [2010] HCA 48; (2010) 273 ALR 122. However, at [30] their Honours quoted [NAME]'s ([NAME] agreeing) caution in Swift v SAS Trustee Corporation [2010] NSWCA 182 at [45] that taken out of context this description could "encourage a slide into impermissible merits review". 138The PAC had before it the [NAME]'s report which the Council criticises as inadequate in certain respects, which resulted, it submitted, in the PAC failing to properly consider certain matters. The Council is not seeking an order to have the [NAME]'s report declared invalid but argues its alleged inadequacies on certain matters impact on the PAC's determination, amounting to a failure by the PAC to consider mandatory relevant matters. As the Minister submitted at par 123 above there was also a great deal of other material before the PAC which is relevant to the failure to consider ground. The PAC's decision is being challenged. It is the failure at that level of decision-making which must be considered in relation to this ground of challenge. In other words, even assuming inadequacy in the [NAME]'s report and the statement relating to compliance, if the issues identified in [NAME] are otherwise considered by the PAC there can be no successful challenge on this ground. 139The Council's submissions focus on the content of the [NAME]'s report which is required by s 75I(1) to be given to the Minister or his or her delegate for consideration of a project application. In this case this applies in relation to the concept plan also by virtue of s 75N. The Respondents submit that is not the only source of material before the PAC. The content required in the [NAME]'s report is identified in s 75I(2). Subsection (e) states that the report is to include a copy of or reference to the provision of any environmental [NAME] instrument that would substantially govern the carrying out of the project and that has been taken into consideration in the [NAME] of the project under Div 2. Subsection (f) refers to any [NAME] undertaken by the [NAME]. Section 75I(2)(g) specifies that a statement relating to compliance is to be included. As outlined above in par 108 - 109 there is reference in the [NAME]'s report to the LEP and the neighbouring (isolated) sites issue. The Council's criticism is that the references are inadequate in addressing [NAME] 1, 4 and 5. 140In [NAME] each of the subsections in s 75I(2) was considered and [NAME] observed that several documents were not material which the [NAME] would produce. This, inter alia, supported her Honour's conclusion at [94] that subsection (g) did not require the [NAME] to prepare a statement relating to compliance with [NAME]. At [95] her Honour stated that s 75I(2)(g) did not impose any obligation on the [NAME] to form an opinion about the matter in the subsection. Her Honour also concluded that the statement relating to compliance could be represented by a report (document) or series of documents and there was no need to have a specific single statement relating to compliance in order to satisfy s 75I(2)(g). Her Honour's reasoning was directed to the argument in that case that there was an absence of a mandatory requirement in the [NAME]'s report because there was no sentence purporting to be a statement relating to compliance, the technical nature of that argument was recognised and rejected at [105]. In this case the statement relating to compliance is expressed to be that of the Department. I do not need to ultimately consider how or whether to apply [NAME]'s findings because of the appropriate approach to the facts in this case. 141Nor is it strictly necessary that I resolve the issue of whether every particular specified in [NAME] is a mandatory relevant consideration which must be considered in the [NAME]'s report and also by the Minister or his or her delegate because of my finding below considering the PAC's determination process as a whole. I agree with the Council's submission at par 116 above that the [NAME]'s report is an important part of the environmental assessment regime under Pt 3A. The level of particularity at which a mandatory matter arises depends on the construction of the relevant statute, recognised by [NAME] in [NAME] at [60] citing [NAME] v [NAME] [2000] HCA 38; (2000) 200 CLR 442 at [23]. In [NAME] ([NAME]) [NAME] ([NAME] concurring) referred to [NAME] and [NAME] in holding that there was a requirement on the Minister in making a decision under Pt 3A to consider the public interest, which operated at a high level of generality. Such a conclusion did not mean that the public interest included all aspects of ecologically sustainable development as mandatory at [45]. The Minister relied on that case to submit that while the preparation of the [NAME]'s report is compulsory, not every matter referred to in [NAME] is a mandatory relevant consideration. 142The statutory framework in this case concerns a project and a concept plan considered under Pt 3A. These are generally large and complex developments. Part 3A provides a comprehensive statutory environmental assessment process. Sections 75F(2) - (3) require the [NAME] to provide [NAME] for a project to a [NAME]. In preparing these the [NAME] is to consult with public authorities and have regard to the need for [NAME] to address issues raised by these authorities. Section 75H(1) requires a [NAME] to submit an [NAME] and if the [NAME] does not consider it adequately addresses [NAME], the [NAME] can require [NAME] to address the matters notified to [NAME]. The [NAME] is publicly exhibited after acceptance by the [NAME] (s 75H(3)). The [NAME]'s report must include under s 75I(2) a copy of [NAME]'s environmental assessment, any environmental assessment undertaken by the [NAME] and a statement relating to compliance with the environmental assessment requirements under the Division (which requirements I infer include the DGEARs). My preliminary view is that given the significance of [NAME] in the Pt 3A environmental assessment framework the particulars specified are individually to be considered mandatory relevant matters for the Minister and his or her delegate. This preliminary finding is necessarily subject to specific statutory provisions which identify that certain matters are not mandatory, a relevant issue in relation to [NAME] 1 and 4.

(i) Failure to consider the LEP/failure to demonstrate consistency (DGEAR 1, 4) 143The Council's argument that there was a failure by the PAC to consider mandatory relevant matters because of inadequate consideration of [NAME] 1 and 4 in the [NAME]'s report is problematic because of the other provisions of Pt 3A and the facts of the case, as highlighted in the Respondents' submissions. [NAME] 1 and 4 require identification and demonstration of compliance with the LEP density and height of buildings provisions . The Minister and [NAME] rely on s 75J(3) and s 75O(3) which specify that environmental [NAME] instruments may be considered by the Minister but do not need to be when determining whether to approve a particular project or concept plan. Part 3A specifically provides that the provisions of an LEP are not mandatory relevant considerations for a determination under Pt 3A. Section 75J and s 75O make optional the consideration of environmental [NAME] instruments which would otherwise apply under Pt 4 when granting development consent. 144The Council's submission that the [NAME]'s report did not comply with s 75I(2) so that the identification of limits in and addressing compliance with the LEP in relation to density limitations were not before the PAC has to be assessed in light of that statutory framework. I agree with the Respondents that the consideration of an environmental [NAME] instrument cannot be a mandatory relevant consideration for the Minister or his delegate in light of the explicit provisions in s 75J and s 75O. Therefore the failure said to arise in the [NAME]'s report that must be considered by the PAC under s 75I(1) cannot result in there being a failure in the PAC's determination to consider the matters specified in [NAME] 1 and 4. 145Further, assuming there was a failure in the [NAME]'s report to adequately consider [NAME] 1 and 4, the circumstances of the PAC's determination must be considered as a whole. The assessment process leading up to it and the PAC's determination make clear that the PAC was aware of the LEP density controls and that the proposed project did not comply with these. Indeed that matter was obvious and is stated in the first sentence of section 4 of the PAC's determination. This states that the Council's [NAME] framework provides for a density of 25 dwellings per hectare and that the PAC was considering a proposal for a density of 75 dwellings per hectare. The LEP and DCP 21 were referred to in numerous reports before the PAC including [NAME]'s [NAME], the [NAME] report and the [NAME]'s report. The Respondents' submissions (the Minister's at par 120 and [NAME]'s at par 129 above) to that effect are accepted. Further, as [NAME] submitted at par 132, its [NAME] was directed to demonstrating to the PAC that the environmental constraints of the site did not prevent a higher density than the Council's controls provided for. Further, the PAC met with the Council as part of the determination process and expressly considered the increased density proposed (section 5.1 of the determination). In these circumstances any failure, assuming there is one, in any of the intermediate steps taken by the [NAME] in relation to the [NAME]'s report is overcome when the PAC's determination process is considered as a whole. There was no failure by the PAC to consider, within the principles identified in par 137 above, the matters raised by [NAME] 1 and 4 in the determination to approve the project and concept plan.

(ii) Isolated sites 146In relation to the issue of isolated sites referred to in [NAME] 5 there is no specific reference to this issue in the PAC's determination. There is no requirement that the PAC refer to this (or any matter) in any determination it may choose to issue as it is not required to give reasons for a determination under Pt 3A in granting approval under s 75J or s 75O. Section 75I(1) requires that the Minister, here the PAC, consider the [NAME]'s report when considering whether to grant approval. The Council submits the consideration of this topic in the [NAME]'s report is legally inadequate and that fatally affects the PAC's determination by omitting to consider a mandatory relevant matter. Once again all the material before the PAC should be considered as it is in the PAC's determination process as a whole which any failure to consider must be established by the Council. As submitted by the Minister and [NAME] (at par 134 above) the correspondence with the two neighbouring owners in [ADDRESS] concerning amalgamation was attached to [NAME]'s [NAME] together with a concept plan showing development potential for those sites in relation to [NAME]'s proposed development. In the [NAME]'s report this topic is identified on the basis that a design plan showing development potential for the neighbouring site are identified. All of this material was before the PAC and it was therefore a matter about which the PAC could properly inform itself. 147The particular criticism made by the Council is that there was no evidence of genuine attempts by [NAME] to amalgamate its site with those of its neighbours. The material in [NAME]'s [NAME] addresses that topic by including its correspondence with the neighbours. These circumstances mean that this ground cannot be sustained on a factual basis and it is not necessary to deal with the Council's submission that the Court can consider whether the statement relating to compliance in the [NAME]'s report was made on a false premise. The Council is unsuccessful on this ground of challenge.

Ground of challenge - PAC's approvals were unreasonable

Council's submissions 148The PAC's determination to approve the concept plan and project were unreasonable, meaning illogical, in the Wednesbury sense. The Council accepts that it has to meet a high hurdle in order to establish this ground. The Further Amended Points of Claim identifies four bases for this ground: that the approvals were based on a density that substantially exceeds the LEP, the height and density approved is at the outer limit of or exceeds what might be justifiable under the [NAME], the decision was made in the absence of adequate strategic studies ordinarily required, and the approvals require the preparation of amended plans which effect a lesser density which require elaborate design changes. 149Firstly, the PAC took its lead from the [NAME]. That document is incapable of supporting this particular approval and was never intended to be used to determine individual development applications, as opposed to informing the drafting of subregional and local environmental [NAME] instruments. Secondly, even if the [NAME] was able to be applied for the site, it does not support the approval of medium rise development at the outer limit of medium density in the [NAME]. It supports at most low rise density between 25 and 60 buildings per hectare of four storey buildings at 60 buildings per hectare. Thirdly, the foregoing emphasises the absence of strategic studies ordinarily required before approvals would be given to a site-specific development. 150The PAC's determination should be read as a whole. This identifies the need for a strategic study of the Warriewood Valley. The defect in the [NAME] report was that it focussed on the three buffer zones around the STP. Nevertheless the PAC decides to make the decision without a comprehensive strategic study and "takes its lead" from the [NAME] (first step of illogicality). The Strategy guides the PAC's conclusions regarding the appropriate development density and height at the site. The only reference to 60 dwellings per hectare is in this context. The next step of illogicality is that the [NAME] identified low to medium rise as less than three storeys and medium density as between 25 and 60 dwellings per hectare. Four out of seven buildings are more than three storeys. The PAC does not approve development of the site within the range of the [NAME]. The high hurdle is overcome in these circumstances.

Minister's submissions 151Wednesbury unreasonableness rather than irrationality or illogicality is relied on, distinguished in [NAME] and [NAME] at p 265 - 273, 294 and p 296. There may be no relevant difference between the two see [NAME] Immigration and Citizenship v SZMDS [2010] HCA 16; (2010) 240 CLR 611 at [131] (Crennan and Bell JJ). 152The stringency of the Wednesbury standard is well known. The decision must amount to "an abuse of power or be so devoid of plausible justification that no reasonable person could have taken that course": Attorney-General (NSW) v Quin [1990] HCA 21; (1990) 170 CLR 1 at 36 - 37; [NAME] at [122] per [NAME]; Save Our Streets Inc v Settree [2006] NSWLEC 570; (2006) 149 LGERA 30 at [31] per [NAME]. The question is whether based on the material before the decision-maker the decision was so unreasonable that no reasonable decision-maker could have come to that decision; Woolworths Ltd v Pallas Newco Pty Ltd [2004] NSWCA 422; (2004) 61 NSWLR 707. 153That the project and concept plan result in greater density than the LEP is accepted. That the exceedances are substantial or at the outer limit of what is justified under the [NAME] is irrelevant. The PAC had various documents before it which justified the exceedences in density, the [NAME] report, the [NAME] traffic report, the [NAME] and the draft [NAME]. 154The [NAME] which is referred to in the PAC's determination report provides for greater density (25 dwellings per hectare) than that provided for in the LEP (17 to 18 dwellings per hectare). This confirms that the current [NAME] controls are below that considered suitable for buffer area 3. 155All the documents speak for themselves and are not suggested to be inadequate. While the PAC's determination report referred to the need for "more thorough and extended strategic study of the Warriewood Valley" that must be understood in context. The PAC concluded that the density proposed in relation to the project and concept plan was not justified contrary to the [NAME] and departmental reports. The PAC conditioned or modified the approvals to reduce the density. The PAC went on to say that if further increases in densities on other land in the Warriewood Valley are to be justified, additional studies will be required. However, further studies were unnecessary for the determination of the subject applications. The PAC was satisfied based on the [NAME] report and the [NAME] traffic report that higher density was justified on merit grounds, that is, based on existing documentation and information. 156Whether the approvals allow the preparation of amended plans requiring elaborate design changes as the Council submits is unclear.

[NAME]'s submissions 157The Council bases its allegation of unreasonableness on four specific allegations in the Further Amended Points of Claim. Firstly, in relation to density exceeding the LEP, local controls do not need to be taken into account in granting a concept or project approval. The lawful exercise of power can always allow for an approval in excess, including substantial excess, of a local control. This is specifically contemplated by, if not endorsed under, the EPA Act; see [NAME] at [208] per [NAME]. 158Secondly, that the approvals are based on height and density that is at the outer limit of or exceeds what might be justifiable based on the [NAME] is an outcome within the range of potential outcomes. This cannot be irrational. 159Thirdly, the approvals were granted "in the absence of adequate strategic studies which would ordinarily be required". This requires by implication that the PAC should have had more information before it and should have conducted more investigations. That is not an indicator of unreasonableness per King v Great Lakes Shire Council (1986) 58 LGRA 366 at 371. It seeks to add additional words into the statutory scheme under s 75O(3) and s 75J(3) in order that some unspecified additional information was required before a decision could be made. The PAC did have multiple reports before it concerning the strategic direction for the Warriewood Valley. The need for another strategic review was not framed by the PAC as a precondition to its ability to determine the application on its merits. The Council cannot make it a precondition. 160Fourthly, the approvals required the preparation of amended plans to effect a lesser density "which will require elaborate design changes". The modifications allowed were a proper exercise of a statutory power and cannot represent irrationality of the required standard per [NAME] . The amended plans do not show elaborate design changes in any event.

Consideration 161The principles which apply to the consideration of whether a decision is unreasonable in the Wednesbury sense are not in dispute. The Council accepts that the hurdle it must overcome to succeed is high. In [NAME] (Mason P and [NAME] concurring) identified relevant formulations at [121] - [125] approving the summary of these in King v Bathurst Regional Council [2006] NSWLEC 505; (2006) 150 LGERA 362 at [63] distinguishing justifiable opinion from sound opinion, to the effect that a court is not to judge whether the opinion is sound. His Honour also referred to [COMPANY] v [NAME] [2005] NSWCA 10; (2005) 138 LGERA 11 at [129] where [NAME] ([NAME] and [NAME] concurring) stated "Perhaps the most appropriate formulation is whether the decision is 'illogical, irrational or lacking a basis in findings or inferences of fact supported on logical grounds'" citing Re [NAME]; Ex parte Applicant S20/2002 [2003] HCA 30; (2003) 77 ALJR 1165 at [52], [37] and [173] and [NAME] Immigration and Multicultural and Indigenous Affairs v SGLB [2004] HCA 32; (2004) 78 ALJR 992 at [38]. A further case considered by [NAME] was [NAME] at [29], [31] - [32] where [NAME] distinguished between a decision the court considers is unreasonable and one the court considers is so unreasonable that no reasonable body could come to it, the latter requiring something overwhelming, citing [NAME] Immigration and Multicultural Affairs v Eshetu [1999] HCA 21; (1999) 197 CLR 611 at 627 per Gleeson CJ and McHugh J. 162Most recently in [NAME] the Court of Appeal ([NAME] and [NAME] concurring) again summarised the authorities at [104] - [107] referring to [NAME] inter alia, and at [108] - [109] on the need to proceed with caution to avoid exceeding a court's supervisory role by engaging in merits review, identified in Puhlhofer v Hillingdon London Borough Council [1986] 1 [NAME] 484 at 518, cited in [NAME] at [41], and by Mason J in Peko- Wallsend at 42 . 163Further cases referred to in submissions included the reference by the Council to [NAME] Immigration and Citizenship v SZIAI [2009] HCA 39; (2009) 259 ALR 429 at [16] French CJ, Gummow, Hayne, Crennan, Kiefel and Bell JJ stating (Heydon J to similar effect) the question as: was there deficiency in process which was so linked to the decision reached as to make it manifestly unreasonable? 164The Minister relied on Belmorgan at [76] - [78] where [NAME] said at [78]: That is not to say that to give grossly inadequate weight to a matter of some importance may not provide a basis for review; however, to qualify as a ground of judicial review, such conduct must satisfy the test of manifest unreasonableness as applied to the exercise of the power: see [NAME] Aboriginal Affairs v Peko-Wallsend Ltd [1986] HCA 40; (1985-86) 162 CLR 24 at 41 (Mason J). It is not helpfully reflected in a supposed obligation to give "realistic" consideration to a particular matter. 165That the PAC is a specialist [NAME] body exercising statutory responsibilities is relevant to the consideration of whether a particular decision is unreasonable in the legal sense for such a body. 166As noted above there is some overlap with the consideration of the no evidence ground as the unreasonableness is said to arise from the reliance of the PAC on the [NAME] in arriving at the density of 60 dwellings per hectare because the [NAME] is not intended as a policy instrument to be applied to site specific assessment of individual sites. It is a [NAME] level strategic [NAME] document. 167When deciding whether to approve the carrying out of a project, s 75J(2) requires the Minister to consider the [NAME]'s report. Subsections (b) and (c) do not apply here. Section 75J(3) does not require compliance with any environmental [NAME] instruments. The discretion to approve projects and concept plans under Pt 3A is largely unconstrained in terms of any specific provisions. [NAME] practice suggests, and the PAC recognised, that a strategic review of the density requirements in Warriewood Valley is necessary but that does not render the PAC's decision to approve the concept plan and the project unreasonable in the legal sense. As identified in relation to the no evidence ground, the PAC was not bound by the Council's [NAME] framework documents such as the LEP, DCP 21 and the [NAME]. It rejected the higher densities in the [NAME] report relied on by the Department. The lack of adequate strategic [NAME] documents available to guide it is recognised by the PAC which recommends that such studies be carried out. It proceeded to grant approvals as it did not consider it was constrained from determining the application before it. There was no constraint in Pt 3A preventing the PAC determining the applications before it in these circumstances. 168Considering the specific grounds raised by the Council, in the circumstances outlined above reliance on the [NAME] for the development of site specific controls was not unreasonable for the reasons I have given in relation to the no evidence ground. Secondly, the PAC did not rely exclusively on the [NAME] in reaching its conclusion on appropriate height and density. Given the evidence before it which supported a greater density on the site of 75 dwellings per hectare it was not therefore unreasonable in applying the outer limit of medium density development described in the [NAME]. Nor was it required to wait for the strategic study it identified as necessary for the [NAME]'s submissions at par 159 are accepted on this part of the Council's case. As I have found that the Council did not succeed on the first ground of challenge relating to uncertainty in relation to the modified plans to be approved by the [NAME], the submission that elaborate design changes were envisaged is not established and cannot support this ground of challenge. 169As identified in [NAME] by [NAME] at [208], referring to the need for a court to avoid exceeding its powers, a claim of irrationality is usually a claim that there was a legally erroneous step. Where the power has been exercised for a proper purpose, no mandatory considerations have been ignored nor impermissible considerations taken into account, the challenge will be hard to make good. To borrow from [NAME] in [NAME] at [32], the question is not whether the Court disagrees with the decision or regards it as unreasonable. If the decision is one that a reasonable decision-maker could have made it is not unreasonable in the Wednesbury sense as Parliament has conferred on the Minister through his delegate the PAC the responsibility to decide whether development consent ought be granted in the Pt 3A context. Alternatively, to borrow from SZIAI , there was no deficiency in process in arriving at the determination to render it manifestly unreasonable. The Council fails on this ground also. 170The Council's Further Amended Summons should be dismissed.
