Re Health Services Union & Anor, Ex parte State of Vic

The State of Victoria sought to prohibit the Health Services Union and its federal secretary from continuing proceedings in the Federal Court of Australia. The State argued that the Federal Court lacked jurisdiction to hear the matter, which concerned alleged breaches of the *Health Services Union Act 1988* (Vic) and the *Constitution Act 1975* (Vic). The dispute centred on whether the Federal Court had the power to entertain a claim that involved the interpretation and application of Victorian state legislation, particularly when the State itself was a party and asserting its sovereign rights.

The primary legal issue before Dawson J was whether the Federal Court possessed jurisdiction to hear and determine a proceeding that involved the interpretation and enforcement of provisions of a Victorian state Act, notwithstanding that the State of Victoria was a party to the proceeding and contended that the Federal Court lacked such jurisdiction. This question engaged fundamental principles of federalism and the division of powers between the Commonwealth and the States under the Australian Constitution.

Dawson J reasoned that the Federal Court's jurisdiction is primarily derived from the Commonwealth Constitution and federal legislation. While the Federal Court can exercise jurisdiction conferred by State legislation, this is generally limited to matters where the State has validly conferred such jurisdiction. In this instance, the State of Victoria had not conferred jurisdiction on the Federal Court to hear disputes concerning the interpretation and enforcement of its own state legislation, especially when the State itself was challenging that jurisdiction. His Honour concluded that the Federal Court did not have the constitutional or statutory power to entertain the proceedings as initiated by the Union, as it would amount to the federal judiciary adjudicating on the internal governance and legislative validity of a State's own laws in a manner not contemplated by the constitutional framework.

Consequently, Dawson J made orders prohibiting the Health Services Union and its federal secretary from continuing the proceedings in the Federal Court of Australia.
