R v Commonwealth Court of Conciliation and Arbitration and Merchant Service Guild of Australasia

The case involved three separate orders nisi for prohibition obtained by shipowners engaged in intra-State shipping against the Commonwealth Court of Conciliation and Arbitration and the Merchant Service Guild of Australasia. The applicants sought to prohibit the Court from proceeding with a plaint and an award made by the President of the Court, arguing that the Court lacked jurisdiction. The core of the dispute concerned whether an "industrial dispute extending beyond the limits of any one State" had been validly created to found the jurisdiction of the Commonwealth Court.

The legal issues before the High Court were whether an industrial dispute, as defined by section 51(xxxv) of the Constitution, had genuinely existed between the shipowners and their employees, and whether such a dispute extended beyond the limits of any one State. Specifically, the Court had to determine if a formal demand and subsequent refusal, without any prior discontent or communication of dissatisfaction from employees to employers, constituted a real and substantial dispute. Additionally, the Court considered whether a single industrial dispute could encompass both inter-State and intra-State shipping, and whether a direction for leave of absence on full pay fell within the Court's jurisdictional powers.

The majority of the Court, comprising Griffith C.J. and Barton J., held that no industrial dispute within the meaning of section 51(xxxv) of the Constitution existed. Their reasoning was that an industrial dispute requires a real and substantial difference with an element of persistency, likely to endanger industrial peace, and is not created by a mere formal demand and refusal. They found that the demand made by the Merchant Service Guild was the first notification of any discontent and was presented as an ultimatum, with no prior knowledge or communication of dissatisfaction from the employees to the shipowners. The Court emphasised that the power under section 51(xxxv) should not be interpreted to allow for the creation of disputes ex mero motu by formal demands, which would effectively transfer the regulation of domestic industrial affairs from the States to the federal Arbitration Court. Isaacs J., in dissent, argued that a demand and refusal, particularly when made in concert by employees across different states, could constitute an industrial dispute extending beyond one state.

The Court ordered that the writs of prohibition should issue, prohibiting the Commonwealth Court of Conciliation and Arbitration from further proceeding in the plaint and award in so far as they related to the applicants. This outcome was based on the majority's finding that the necessary jurisdictional prerequisite of a genuine industrial dispute extending beyond one State had not been established.
