Re Wakim; Ex parte McNally

The High Court of Australia considered challenges to the constitutional validity of legislation that cross-vested jurisdiction between federal, State, and Territory courts. The proceedings involved parties such as Re Wakim and Ex parte McNally, who sought to argue that the cross-vesting legislation was invalid. The core of the dispute revolved around whether Chapter III of the Australian Constitution, which deals with the judicial power of the Commonwealth, permitted such a broad conferral of jurisdiction.

The legal issues before the Court included whether Chapter III of the Constitution exhaustively defined the original jurisdiction that could be conferred on federal courts, and whether State or Commonwealth legislative power extended to vesting State jurisdiction in federal courts. The Court was also required to consider whether Commonwealth laws applying in Territories could be considered "laws made by the Parliament" for the purposes of Chapter III, and whether the validity of such legislation depended on legislative purpose, intent, or consent, particularly in the context of "co-operative federalism." Furthermore, the Court had to determine the precedential weight of an equally divided previous decision and whether issues decided in earlier proceedings were subject to issue estoppel or res judicata.

The Court reasoned that the Australian Constitution does not contain an express prohibition against the cross-vesting of jurisdiction. It noted that Section 77(iii) of the Constitution explicitly allows for the federal Parliament to invest State courts with federal jurisdiction, indicating that a complete separation between the judicial powers of the Commonwealth and the States was not intended. The Court interpreted Chapter III and the Constitution as a whole, considering the envisaged structure of a federal nation with cooperating States and Territories. The majority found that the cross-vesting legislation, in both its general and specific manifestations, was constitutionally valid, rejecting the argument that Chapter III imposed rigid constraints that would render such legislation invalid.

The application was dismissed with costs.
