R v Commonwealth Court of Conciliation and Arbitration; Ex parte

This case concerned an application for a writ of prohibition directed to the Commonwealth Court of Conciliation and Arbitration and its officers, following orders made by Dunphy J. The initial dispute arose from an application by John Patrick O'Shea, a member of the Boilermakers' Society of Australia, seeking an inquiry into alleged irregularities in a union election held in June and July 1949. The application was lodged on 3 August 1949, and subsequently referred to the Court, which declared the election void and ordered a new election.

The legal issues before the High Court included whether the Commonwealth Conciliation and Arbitration Act 1949, which introduced new provisions for dealing with disputed elections, applied retrospectively to an election that had commenced before its enactment but was completed afterwards. The Court also had to determine whether the application for inquiry was validly lodged given the timing of the relevant regulations, and whether the orders made by Dunphy J. for the conduct of the new election, including the appointment of returning officers and the prescription of safeguards, were within the Court's jurisdiction.

The High Court, by majority, held that Section 96A of the Commonwealth Conciliation and Arbitration Act 1904-1949 applied to elections that had not been completed before the 1949 Act came into operation, allowing reliance on irregularities occurring before the regulations were promulgated. The Court found that the application was properly lodged. Furthermore, it was held that the Court was not bound to prescribe all safeguards itself but could authorise returning officers to do so, and that the union's rules, even if defective, were the rules to which the Court referred. The Court also determined that it had the power to appoint a person to act alone as returning officer if the union's returning officer failed to cooperate, and that such an order was a supplementary order within the meaning of the Act.

The application for prohibition was dismissed. The Court found that procedural matters did not go to the jurisdiction of the Court and that prohibition would not lie where only a question of time was involved, nor should it issue against an officer acting in pursuance of a court order.
