8. Mr [NAME] submitted to the tribunal that where alterations had been
carried out by [NAME] and were present at the date of the
assignment of the lease to the respondents in 2015, the latter however,
should still be regarded as being in breach of the lease in respect of those
(earlier) alterations having effectively ‘adopted’ them. 9. Mr [NAME] submitted that Paragraph 3, Fifth Schedule of the lease on which the applicant relied was so wide in its wording, that all the unauthorised alterations that had been carried out in the property were ‘caught’ by this clause. 10. None of the applicant’s evidence was contested by the respondents. Mr
[NAME] informed the tribunal however, that many of the
alterations had been carried out after a water-leak had occurred in
2021 and repairs and renovations were required. Although not a matter
for the tribunal, Mr [NAME] indicated the respondents were willing
to regularise the position with the applicant. The tribunal’s reasons 11. The tribunal finds the evidence relied upon by the applicant both
comprehensive and persuasive. In particular, the tribunal finds the
expert evidence of Mr [NAME] to be detailed and convincing and the
tribunal is satisfied the applicant has met the burden of proof and
established the respondent has breached clauses 3 and 4 of the lease in
addition to paragraphs 3, 7, 9 and 22 of the Fourth Schedule as well as
paragraphs 3 and 10 of the Fifth Schedule. 12. The tribunal also finds the respondent failed to challenge the applicant’s
evidence or any of the witnesses called to give evidence on its behalf,
thereby impliedly accepting the evidence of the alterations and the
consequent breaches of the lease. 13. In conclusion, the tribunal finds the applicant has proved its case and
that the respondents are in breach of the terms of the lease dated 16
8
December 1988 pursuant to s.168(4) of the Commonhold and Leasehold
Reform Act 2002.
