R v Portus; Ex parte Federated Clerks Union of Australia

The High Court of Australia considered an application for a writ of prohibition brought by the Federated Clerks Union of Australia (the prosecutor) against Mr. J. H. Portus, a Conciliation Commissioner. The prosecutor sought to prevent the Commissioner from proceeding with an alleged industrial dispute between the Australasian Transport Officers' Federation (the Federation) and Qantas Empire Airways Ltd. (Qantas). The core of the dispute was whether an industrial dispute, extending beyond the limits of one State, had been validly created by the Federation serving a log of demands on Qantas, given the prosecutor's contention that Qantas employees were ineligible for membership in the Federation.

The legal issues before the High Court were twofold: first, whether an industrial dispute extending beyond the limits of a single State existed between the Federation and Qantas; and second, whether the employees of Qantas were eligible for membership in the Federation, thereby granting the Federation the authority to represent them in an industrial dispute. The prosecutor argued that Qantas employees were not "salaried officers of the Crown" as defined by the Federation's rules, and therefore the Federation could not lawfully represent them, meaning no cognisable dispute could arise. The prosecutor also contended that the dispute was not genuinely inter-State due to the small number of employees in Queensland.

The Court, in a majority decision, held that an industrial dispute did exist and that the order nisi for prohibition should be discharged. The Court reasoned that the definition of "salaried officers of the Crown" in the Federation's rules, which included "Employees of any person or corporation employing persons at an annual salary rate on behalf of the Government of the Commonwealth or any of the States," was broad enough to encompass Qantas employees. Despite Qantas being a company incorporated under State law, the Commonwealth's acquisition of all its shares and its sole right to appoint directors meant that Qantas was effectively operating "on behalf of the Commonwealth Government" in a commercial and industrial sense, even if not in a strict legal agency sense. The Court also found that the existence of employees in both New South Wales and Queensland was sufficient to establish an inter-State dispute, regardless of the numerical disparity between the states, as the dispute concerned the terms of employment across Qantas's operations.

Consequently, the High Court discharged the order nisi for prohibition. This meant that the Conciliation Commissioner was permitted to proceed with hearing the alleged industrial dispute between the Australasian Transport Officers' Federation and Qantas Empire Airways Ltd.
