Shanahan v Scott

Shanahan v Scott concerned an appeal to the High Court of Australia from a decision of the Supreme Court of Victoria. The appellant, Shanahan, had been charged with contravening regulation 44 of the Egg and Egg Pulp Marketing Board Regulations 1953, which prohibited any person from placing eggs in cold storage without the consent of the Egg and Egg Pulp Marketing Board. The Supreme Court had made absolute an order nisi to review a decision of a magistrate who had dismissed the information, finding the regulation to be invalid.

The central legal issue before the High Court was whether regulation 44 was ultra vires the powers conferred by the Marketing of Primary Products Acts 1935-1953 (Vict.). Specifically, the court had to determine if the regulation fell within the general power to make regulations for purposes necessary or expedient for the administration of the Act or for carrying out its objects, or within the specific power to make regulations for or with respect to regulating the storage of the commodity.

A majority of the High Court (Dixon C.J., Williams, Webb, and Fullagar JJ.) held that regulation 44 was ultra vires. Their reasoning was that the regulation, by imposing a prohibition subject to the Board's consent, went beyond the power to "regulate" storage as contemplated by the Act. Furthermore, the majority found that the regulation's broad scope, extending to eggs not vested in the Board and those already sold by the Board, exceeded the legislative plan of collective marketing. They concluded that the regulation attempted to supplement, rather than complement, the Act's provisions by extending regulation into a field independent of the Board's marketing powers. Kitto J. dissented, finding that the regulation was a necessary and expedient measure for the effective marketing of eggs, given their perishable nature and fluctuating supply, and thus fell within the regulation-making power.

The High Court allowed the appeal with costs, discharged the order of the Supreme Court, and ordered that the order nisi to review be discharged with costs.
