Re Coldham & Ors; Ex parte Lee

The applicants sought prerogative writs of prohibition, certiorari, and mandamus directed to Deputy Presidents and Commissioners of the Australian Conciliation and Arbitration Commission. The dispute concerned the Commission's power to condition the registration of an employee association, particularly by requiring a narrowing of its eligibility rules to exclude certain members, in circumstances where the association sought to cover employees in an industry not previously represented by a registered organisation. The proceedings before the Commission involved appeals from decisions of the Industrial Registrar concerning the registration of three associations of teaching employees.

The central legal issue before the High Court was whether the Conciliation and Arbitration Commission, on appeal from the Industrial Registrar, had the power to impose conditions on the registration of an employee association that required it to restrict its eligibility rules, thereby limiting the scope of employees it could represent. This question arose in the context of associations seeking federal registration in areas previously unrepresented, following a re-evaluation of the scope of section 51(xxxv) of the Conciliation and Arbitration Act and the definition of "industry". The Commission, by majority, had determined that it could impose such conditions.

The High Court considered the provisions of the Conciliation and Arbitration Act and relevant regulations. The applicants argued that the Commission's power to register an organisation did not extend to requiring a reduction in the scope of its membership eligibility, particularly when the organisation was seeking to enter "virgin territory" industrially. The Commission's majority decision, which the applicants sought to challenge, had allowed for such conditions to be imposed, effectively forcing the associations to narrow their eligibility criteria before registration could be granted. The Court was required to determine the extent of the Commission's discretion in relation to the conditions of registration under the Act.
