The binding legal principles established are: (1) A universitas (incorporated association) can only function and be run in accordance with its constitution, and anything done in breach of the constitution is a nullity with no legal consequence; (2) The legal basis of an unincorporated voluntary association is the contract between the associates, and courts must determine whether claimed acts comply strictly with prescribed procedures; (3) To have locus standi to sue on behalf of an association, a person must have constitutional authority - majority support alone is insufficient; (4) Members have freedom to determine their governing rules, and those rules must be respected; (5) A subordinate body within an association cannot lawfully invalidate decisions made by the supreme constitutional organ of that association; (6) To justify participation in litigation, a party must show direct and substantial legal interest in the subject-matter and outcome, not merely financial or indirect interest.
