Gonzwa v Commonwealth

In this case, Jacob Gonzwa, an alien medical practitioner who had graduated in Poland and practised in Europe before arriving in Australia in 1938, brought an action against the Commonwealth of Australia and members of the Commonwealth Alien Doctors Board. Gonzwa practised medicine in Sydney without being registered under New South Wales law. He alleged that the defendants threatened to enforce the National Security (Alien Doctors) Regulations against him, which he claimed would cause him serious loss and inconvenience. Gonzwa sought a declaration that regulation 16(1) of these Regulations was invalid and ultra vires, and an injunction restraining the defendants from enforcing the Regulations. The defendants demurred to the statement of claim.

The central legal issue before the High Court was the validity of regulation 16(1) of the National Security (Alien Doctors) Regulations, and by extension, regulations 1 to 15, under the defence power of the Commonwealth, as authorised by the National Security Act 1939-1943. Specifically, the Court had to determine whether these regulations, which dealt with the licensing and practice of medicine by aliens, were sufficiently connected to the defence of the Commonwealth to be a valid exercise of the executive power during wartime. The plaintiff argued that the regulations, particularly regulation 16(1), were not genuinely for defence purposes but rather intruded upon matters within the constitutional powers of the States, such as the regulation of the medical profession.

A majority of the High Court, comprising Rich, McTiernan, and Williams JJ., held that regulations 1 to 15 and regulation 16(1) were within the defence power. They reasoned that the war had created a significant shortage of medical practitioners due to the enlistment of doctors for the armed forces, impacting both military and civilian health services. The Regulations were seen as a comprehensive scheme to address this shortage by enabling qualified aliens to practise medicine, thereby ensuring the continued provision of essential medical services for the civilian population and supporting the war effort. Regulation 16(1) was considered a necessary part of this scheme, acting as a sanction to ensure that only qualified and licensed aliens could practise, and preventing potential exploitation or harm to the public. Latham C.J. agreed that regulations 1 to 15 were valid, but dissented on regulation 16(1), finding it to be purely prohibitory and unrelated to defence. Starke J. also dissented, agreeing with the Chief Justice that regulation 16(1) had no connection to the defence of the Commonwealth.

By a majority decision, the demurrer was upheld in relation to regulations 1 to 15 and regulation 16(1), meaning these regulations were found to be valid. The Court's reasoning emphasised the broad scope of the defence power during wartime, allowing for measures that could conceivably aid the prosecution of the war, including ensuring the health and well-being of the civilian population when that was directly impacted by war exigencies.
