Carbines v Powell

The appellant, an Inspector of Wireless Licences, appealed to the High Court of Australia from a decision of a Police Magistrate in Victoria. The Police Magistrate had dismissed an information laid by the appellant against the respondent, A. L. Powell, for manufacturing wireless receiving equipment without a dealer's licence, contrary to regulation 92 of the Wireless Telegraphy Regulations. The Magistrate's decision was based on his finding that regulation 92 was invalid.

The central legal issue before the High Court was whether regulation 92 of the Wireless Telegraphy Regulations, which prohibited the manufacture, sale, or hire of broadcast receiver equipment without a dealer's licence, was a valid exercise of the power conferred by section 10 of the Wireless Telegraphy Act 1905-1919. This section empowered the Governor-General to make regulations not inconsistent with the Act that were necessary or convenient for carrying out or giving effect to the Act.

The Court, in separate judgments, unanimously held that regulation 92 was invalid and ultra vires the powers granted by the Act. The Justices reasoned that while the Act granted the Commonwealth a monopoly over the establishment, erection, maintenance, and use of stations and appliances for transmitting and receiving wireless messages, and provided for licensing and fees for such purposes, it did not extend to regulating the manufacture of such equipment. The power to make regulations was confined to matters necessary or convenient for carrying out the Act's core purpose, which was the transmission and reception of wireless messages, not the antecedent act of manufacturing the apparatus. The Court emphasised that the power to regulate did not extend to prohibiting trades or activities not expressly or implicitly covered by the Act, and that the regulation in question supplemented rather than complemented the powers granted by Parliament. Consequently, the appeal was dismissed.
