Section 63 — Criminal Code: Unlawful assembly

An unlawful assembly is an assembly of three or more persons who, with intent to carry out any common purpose, assemble in such a manner or so conduct themselves when they are assembled as to cause persons in the neighbourhood of the assembly to fear, on reasonable grounds, that they will disturb the peace tumultuously; or will by that assembly needlessly and without reasonable cause provoke other persons to disturb the peace tumultuously. Persons who are lawfully assembled may become an unlawful assembly if they conduct themselves with a common purpose in a manner that would have made the assembly unlawful if they had assembled in that manner for that purpose. Persons are not unlawfully assembled by reason only that they are assembled to protect the dwelling-house of any one of them against persons who are threatening to break and enter it for the purpose of committing an indictable offence therein.
