R v Vizzard

The case of *Ex Parte Hill* concerned a challenge to the validity of the New South Wales State Transport (Co-ordination) Act 1931. The appellant, Price Alexander Hill, was charged with operating a public motor vehicle in New South Wales without a licence, contrary to section 12 of the Act. The vehicle in question was used exclusively for transporting goods from Melbourne, Victoria, to Wagga Wagga, New South Wales, and was registered in both states but not licensed under the New South Wales Act. The appellant contended that the Act, as applied to his inter-State transport operations, contravened section 92 of the Commonwealth Constitution, which guarantees freedom of trade, commerce, and intercourse among the States. The matter was removed to the High Court of Australia.

The central legal issue before the High Court was whether the provisions of the State Transport (Co-ordination) Act 1931 of New South Wales, by requiring a licence for the operation of a public motor vehicle engaged in inter-State transport, infringed section 92 of the Commonwealth Constitution. This required the Court to consider the scope and application of section 92, particularly in relation to State legislation that regulated or controlled transport facilities, and whether such regulation constituted an impermissible interference with inter-State trade, commerce, and intercourse. The Court also had to determine the appropriate tests for assessing whether State legislation transgressed the freedom guaranteed by section 92.

A majority of the High Court, comprising Gavan Duffy C.J., Rich, Evatt, and McTiernan JJ., held that the provisions of the State Transport (Co-ordination) Act 1931 did not contravene section 92 of the Constitution. The Court reasoned that the Act, in its application to the appellant's circumstances, did not unduly interfere with the freedom of inter-State trade, commerce, and intercourse. The majority applied principles established in previous cases, including *W. & A. McArthur Ltd. v. State of Queensland* and *James v. Cowan*, to determine that the State's regulatory measures, in this instance, did not create a barrier to inter-State commerce. Starke and Dixon JJ. dissented from this conclusion.

The High Court dismissed the rule nisi for prohibition. Consequently, the conviction of the appellant under the State Transport (Co-ordination) Act 1931 was upheld.
