R v Commonwealth Court of Conciliation and Arbitration

The parties to this matter were the Brisbane Tramways Company Ltd. and the Municipal Tramways Trust, Adelaide, seeking writs of prohibition against the Commonwealth Court of Conciliation and Arbitration and its President, and the Australian Tramway Employees Association. The dispute concerned an award made by the President of the Commonwealth Court of Conciliation and Arbitration, with the applicants seeking to prohibit the Court from further proceeding against them based on this award. A preliminary objection was raised by the Australian Tramway Employees Association, arguing that the High Court lacked jurisdiction to issue prohibition to the Commonwealth Court of Conciliation and Arbitration.

The legal issues before the High Court were whether the jurisdiction to issue writs of prohibition was original or appellate, and whether the High Court possessed original jurisdiction to issue such writs to the President of the Commonwealth Court of Conciliation and Arbitration. Further, the Court had to determine if the President of the Commonwealth Court of Conciliation and Arbitration qualified as an "officer of the Commonwealth" for the purposes of section 75(v) of the Constitution, and whether section 31 of the Commonwealth Conciliation and Arbitration Act 1904-1911, as amended, validly removed the High Court's power to issue prohibition.

The Court reasoned that the jurisdiction to issue prohibition is inherently original, not appellate, distinguishing it from the process of appeal which involves reviewing the merits of a case. It was held that section 75(v) of the Constitution confers original jurisdiction upon the High Court to issue writs of prohibition against officers of the Commonwealth. The Court concluded that the President of the Commonwealth Court of Conciliation and Arbitration, regardless of whether acting in an arbitral or judicial capacity, is an officer of the Commonwealth within the meaning of section 75(v). Consequently, section 31 of the Commonwealth Conciliation and Arbitration Act, which purported to remove the High Court's power to issue prohibition, was deemed invalid to the extent it sought to divest the Court of this constitutional jurisdiction. The Court affirmed its prior decision in *R. v. Commonwealth Court of Conciliation and Arbitration Ex parte Whybrow & Co.* on this point, while noting that while not strictly bound by prior decisions, they would only be overturned if manifestly wrong.

The preliminary objection was overruled, and the orders nisi for prohibition were to be heard on their merits.
