R v Commonwealth Conciliation and Arbitration Commission; Ex parte

The case involved an application for a writ of prohibition by the Australian Foremen Stevedores' Association and two of its members against the Commonwealth Conciliation and Arbitration Commission. The application sought to prevent the Commission from hearing appeals lodged by certain waterside workers, including George Buchan, against suspensions of their registration by the Australian Stevedoring Industry Authority. The core of the dispute concerned whether these suspensions were legally effective and therefore capable of forming the subject matter of an appeal.

The legal issues before the High Court were whether the Commonwealth Conciliation and Arbitration Commission had jurisdiction to hear the appeals, and alternatively, whether it had jurisdiction to inquire into allegations of assault by the prosecutors as part of those appeals. Specifically, the Court had to determine if the suspensions of the waterside workers' registrations were ever legally effective, and if so, whether the subsequent purported cancellation of these suspensions by the Authority extinguished the right of appeal. The Court also considered whether the Commission's jurisdiction extended to investigating matters like alleged assaults, which were argued to be outside the scope of an appeal against a suspension.

A majority of the High Court (Dixon C.J., Fullagar, Taylor, and Windeyer JJ.) held that for a suspension of registration to be legally effective, it must be recorded in the register kept at the port. In this instance, no entry was made in the register or on the registration card concerning the purported suspensions. Consequently, the suspensions were ineffective, and there was no subject matter upon which the Commission could exercise its appellate jurisdiction. The Court reasoned that the Stevedoring Industry Act did not grant the Authority power to revoke a suspension once it had taken effect, except in the limited circumstance of suspending registration pending an inquiry. Therefore, prohibition was granted to restrain the Commission from entertaining the appeals. McTiernan J., dissenting, held that the Act conferred upon the Commission the final determination of whether a suspension had occurred, and that the Authority did not have the power to revoke a cancellation or suspension under section 36.
