R v Commonwealth Court of Conciliation and Arbitration; Ex parte Whybrow & Co

This case involved an application for a writ of prohibition brought by Whybrow & Co. and other employers in the boot manufacturing industry against the Commonwealth Court of Conciliation and Arbitration, its President, and the Australian Boot Trade Employés Federation. The employers sought to set aside an award made by the Court, arguing that the Commonwealth Conciliation and Arbitration Act 1904 was unconstitutional, that no genuine industrial dispute existed, and that the award itself was invalid in part.

The High Court was required to determine several key legal issues. Firstly, it had to consider the constitutional validity of the Commonwealth Conciliation and Arbitration Act, specifically whether the Parliament had the power to legislate with respect to conciliation and arbitration for the prevention and settlement of industrial disputes extending beyond the limits of any one State, and the meaning of "arbitration" in this context. Secondly, the Court needed to ascertain whether a genuine industrial dispute, extending beyond one State, had been established by the Federation. Finally, the Court had to determine if certain provisions of the award were invalid, and if so, whether these invalid parts were severable from the rest of the award, rendering the entire award void or allowing it to stand in part. The Court also considered its own jurisdiction to issue prohibition against the Commonwealth Court of Conciliation and Arbitration.

The Court held that the Commonwealth Conciliation and Arbitration Act was not ultra vires the Constitution. It reasoned that the Act's provisions for compulsory arbitration and the tribunal's selection by parties were permissible under the constitutional grant of power. The Court applied tests of severability to determine if the invalid portions of the Act or award could be excised without fundamentally altering the law's purpose. Regarding the existence of a dispute, the Court clarified that a demand and refusal were not automatically sufficient to establish a genuine dispute, and that the High Court was not bound by the President's finding on this matter. The Court also found that the President had improperly delegated powers to a board of reference and that certain wage provisions for apprentices were beyond the scope of the dispute or improperly determined.

Ultimately, the rule nisi for prohibition was enlarged. While the Act itself was found to be constitutional, the Court determined that parts of the award were invalid. However, because the invalid portions of the award were found to be severable from the valid parts, the rule nisi was not made absolute to quash the entire award. Instead, the Court allowed the valid parts of the award to stand, effectively modifying the award by excising the offending provisions.
