Armstrong v Victoria (No 2)

In *Armstrong v Victoria (No 2)*, the plaintiffs, representing various road transport associations, challenged the validity of certain Victorian legislation. They sought declarations that Part II of the *Commercial Goods Vehicles Act 1955* (Vic) and specific sections of the *Motor Car Act 1951* (Vic) were invalid or inapplicable to vehicles engaged in inter-State trade and commerce, arguing they infringed Section 92 of the Australian Constitution. The defendants, the State of Victoria and associated bodies, contended that the impugned provisions imposed legitimate charges for road wear and tear and vehicle registration, which did not violate Section 92.

The High Court was required to determine two primary legal issues. Firstly, whether the charge imposed by Part II of the *Commercial Goods Vehicles Act 1955* for wear and tear on public highways, calculated on a per-ton-mile basis, was a valid imposition on vehicles engaged in inter-State trade. Secondly, the Court had to consider the validity of the substantial registration fees imposed by the *Motor Car Act 1951* on vehicles, including those exclusively used in inter-State commerce.

A majority of the High Court, comprising Dixon C.J., McTiernan, Williams, and Fullagar JJ., held that Part II of the *Commercial Goods Vehicles Act 1955* did not infringe Section 92 of the Constitution and validly applied to vehicles used in inter-State trade. This decision followed previous authority which suggested that states could impose reasonable charges on inter-State carriers as compensation for road wear and tear. However, a different majority, consisting of Dixon C.J., McTiernan, Williams, Webb, Kitto, and Taylor JJ., found that the registration provisions of the *Motor Car Act 1951* could not validly apply to vehicles used exclusively in inter-State trade and commerce due to Section 92. Webb, Kitto, and Taylor JJ. dissented on the first issue, while Fullagar J. dissented on the second.
