Re Finance Sector Union of Australia; Ex parte Financial Clinic (Vic) Pty Ltd

The applicant, Financial Clinic (Vic) Pty Ltd, sought a writ of prohibition to prevent the Finance Sector Union of Australia from proceeding with a ballot for the election of union officials. The dispute concerned the eligibility of certain members to vote in the ballot, with the applicant arguing that the union's rules, as interpreted by the union, improperly excluded eligible members. The matter came before the High Court of Australia.

The central legal issue before the High Court was whether the rules of the Finance Sector Union of Australia, concerning the eligibility of members to vote in an election for union officials, were valid and had been correctly interpreted and applied by the union. Specifically, the court had to determine if the union's interpretation and application of its rules resulted in the unlawful exclusion of members who were otherwise entitled to vote.

The High Court, in a joint judgment, held that the rules of the union, when properly construed, did not permit the exclusion of members in the manner asserted by the union. The Court found that the union's interpretation of its rules was erroneous and that the proposed ballot was therefore invalid. The principles applied by the Court centred on the proper construction of union rules and the fundamental right of members to participate in the democratic processes of their organisation. The Court emphasised that union rules must be interpreted in a way that upholds the democratic rights of members and that any exclusion must be clearly and unambiguously provided for in the rules.

The High Court made absolute the order nisi for a writ of prohibition, thereby preventing the Finance Sector Union of Australia from proceeding with the ballot as proposed.
