R v Commonwealth Industrial Court; Ex parte

The applicant, the Commonwealth, sought a writ of prohibition against the Commonwealth Industrial Court, directed to the Honourable Mr. Justice Dunphy, a judge of that court. The dispute concerned the validity of an award made by the Commonwealth Court of Conciliation and Arbitration, which the Commonwealth argued was beyond the Court's constitutional power.

The central legal issue before the High Court was whether the Commonwealth Court of Conciliation and Arbitration had the constitutional authority to make an award that purported to regulate the terms and conditions of employment of persons employed by the Commonwealth itself, specifically in relation to the construction of a lighthouse. The Commonwealth contended that the arbitration power under section 51(xxxv) of the Constitution did not extend to making awards binding upon the Commonwealth as an employer.

The Court, applying the principles established in previous cases concerning the scope of federal industrial power, held that the Commonwealth Court of Conciliation and Arbitration did not possess the constitutional power to make an award binding upon the Commonwealth in its capacity as an employer. The majority reasoned that the power to make laws with respect to conciliation and arbitration for the prevention and settlement of industrial disputes extending beyond the limits of any one State (section 51(xxxv)) did not extend to the Commonwealth itself. The Court found that the award made by the Industrial Court was therefore invalid.

Consequently, the High Court made absolute the order nisi for a writ of prohibition, preventing the Commonwealth Industrial Court from enforcing the award.
