Case opinions
(7:0) Section 112 of the Customs Act 1901 (Cth) was a constitutionally valid law under the trade and commerce power (per Barwick CJ, McTiernan, Gibbs, Stephen, Mason, Jacobs & Murphy JJ)

Murphyores Inc Pty Ltd v Commonwealth (1976) 136 CLR 1; [1976] HCA 20, was a case decided in the High Court of Australia regarding the scope of the trade and commerce power in section 51(i) of the Constitution.

Background

Section 112 of the Customs Act 1901 (Cth) prohibited the exportation of mineral sands unless authorised by the Minister. Murphyores Inc Pty Ltd, which held leases from the state of Queensland to mine mineral sands on Fraser Island, sought permission from the Minister to export mineral sands. Such authorisation was withheld pending the outcome of an environmental inquiry. Murphyores challenged the constitutional validity of prohibition and sought an injunction to the study, and a declaration that the Minister cannot make a prohibition for environmental purposes.

Decision

In a unanimous decision, the court held the legislation was a valid exercise of the trade and commerce power. Section 51(i) was a non-purposive power, and the only relevant factor was the subject matter of trade and commerce. The motive and purpose behind the legislation was irrelevant.
