Huddart Parker Ltd v The Commonwealth

Huddart Parker Ltd and others brought an action against the Commonwealth of Australia seeking a declaration that the Transport Workers (Waterside) Regulations 1930 were invalid, either because they were not authorised by the Transport Workers Act 1928-1929, or because the Act itself was beyond the constitutional powers of the Commonwealth Parliament. The regulations, made under the Act, stipulated that priority in the engagement of waterside workers for oversea and inter-State vessels must be given to members of the Waterside Workers' Federation.

The central legal issues before the Full Court were whether section 3 of the Transport Workers Act 1928-1929 validly empowered the Governor-General to make regulations that mandated preference to union members in the engagement of waterside workers, and whether such a regulation was consistent with the Act itself and within the constitutional powers of the Commonwealth, particularly the trade and commerce power. The court was also required to consider whether the regulation was inconsistent with Part III of the Act, which established a licensing system for transport workers.

A majority of the Court, comprising Rich, Dixon, and Evatt JJ., held that the regulation was a valid exercise of the Commonwealth's legislative power. They reasoned that section 3 of the Act, when read in conjunction with the Acts Interpretation Act, conferred the power to make regulations concerning the engagement of transport workers, and that the regulation in question, by requiring preference to union members, fell within this power. The majority viewed the regulation as directly regulating an operation of trade and commerce, specifically the selection of individuals to perform work on ships engaged in inter-State and oversea trade, and thus within the scope of the Commonwealth's trade and commerce power. Conversely, Gavan Duffy C.J. found the regulation to be inconsistent with Part III of the Act, while Starke J. considered both the Act and the regulation to be invalid.

The Court ultimately dismissed the plaintiffs' application for an injunction. The majority's reasoning established that the Commonwealth Parliament could legislate to regulate the engagement of workers involved in inter-State and oversea trade, including provisions that granted preference to union members, provided such legislation was framed as a law with respect to trade and commerce.
