Forsyth v Deputy Commissioner of Taxation

The case of *Forsyth v Deputy Commissioner of Taxation* concerned an appeal to the High Court of Australia regarding the jurisdiction of the District Court of New South Wales to hear and determine an action brought by the Deputy Commissioner of Taxation to recover a penalty under the *Income Tax Assessment Act 1936* (Cth). The appellant, Mr Forsyth, argued that the District Court lacked the necessary federal jurisdiction to entertain the proceedings.

The central legal issues before the High Court were whether section 39(2) of the *Judiciary Act 1903* (Cth) conferred federal jurisdiction on the District Court of New South Wales to hear such a recovery action, and whether section 44(1)(a) of the *District Court Act 1973* (NSW) constituted a limitation on that jurisdiction within the meaning of the *Judiciary Act*. A further issue involved the statutory interpretation of section 44(1)(a) of the *District Court Act*, specifically whether it should be construed as having an ambulatory or fixed-time construction, and whether subsequent regulatory changes reallocating work between Supreme Court divisions affected the District Court's jurisdiction.

A majority of the High Court dismissed the appeal. The majority reasoned that section 39(2) of the *Judiciary Act* invests State courts with federal jurisdiction to the extent of their ordinary jurisdiction, provided that the action falls within the limits of that jurisdiction as defined by State law. They held that section 44(1)(a) of the *District Court Act*, which defined the District Court's jurisdiction by reference to the allocation of work between the Supreme Court divisions, was intended to be ambulatory. Therefore, a subsequent reallocation of work between Supreme Court divisions did alter the jurisdiction of the District Court. Consequently, the District Court had been invested with federal jurisdiction to hear the recovery action. Kirby J dissented, finding the interpretation of the legislation urged by the appellant to be correct.
