Where ministerial records show that a block of stands was allocated to a specific housing cooperative, members of that cooperative who were allocated stands within that block are the lawful holders of rights and interests in those properties. Occupation by members of a different housing cooperative, to which the block of stands was never allocated, is illegal and confers no legal rights or locus standi to defend against eviction. For a declaratory order to succeed under section 14 of the High Court Act, the applicant must: (1) be an interested person in an existing, future or contingent right or obligation, and (2) present a case proper for the court to exercise its discretion in granting such relief.
