State of Victoria, Ex parte- Re Sutton

The High Court of Australia heard an ex parte application by the State of Victoria, represented by Mr. Sutherland, seeking an order nisi for a writ of prohibition against the Chief Justice of the Industrial Relations Court of Australia. The application also sought a stay of proceedings in that court. While the application was ex parte, other parties to the substantive proceeding were served and appeared, seeking leave to be heard on the stay application.

The central legal issue before the High Court was whether the Industrial Relations Court of Australia, and specifically Chief Justice Wilcox, had wrongly assumed jurisdiction in a matter concerning the management and administration of the CFMEU, including the validity of amalgamation agreements with the deregistered BLF and subsequent rule changes. The State of Victoria argued that the construction of section 258 of the Industrial Relations Act 1988, as contended by the applicants in the Industrial Relations Court, could operate to override state legislation, raising significant constitutional concerns.

The High Court, in refusing the application, reasoned that it was premature. The court emphasised that the proceedings in the Industrial Relations Court were at an interlocutory stage and should be permitted to run their full course, including any potential appeals. The High Court considered it highly undesirable to adjudicate on the complex constitutional questions without the benefit of the factual context and the initial determination by the court below. The court noted that any jurisdictional error could be tested on appeal, which is generally the preferable avenue over prerogative writs.
