Constitution and Communist Case
Case file: Australian Communist Party v Commonwealth (1951)
After the Second World War, the Menzies Government argued that communism threatened Australia’s security. In 1950, the Commonwealth Parliament passed the Communist Party Dissolution Act. The Act declared the Australian Communist Party unlawful, provided for its dissolution and allowed certain people and organisations to be declared communist, with serious consequences for them. The Commonwealth defended the law mainly by relying on its defence power in section 51(vi) of the Constitution, together with other supporting powers. The Communist Party and others challenged the Act in the High Court. In 1951, by a 6–1 majority, the Court held the Act invalid. The majority concluded that the law could not be supported by the constitutional powers relied on. Parliament could not make a law constitutional simply by declaring that an organisation was a threat; the law still had to fall within a power granted by the Constitution. The Court did not decide that communism was harmless, nor did it establish an absolute constitutional right for political parties to operate. The case is an example of judicial review: a court examining whether a law is constitutionally valid. It also illustrates federalism, because the Commonwealth Parliament has only the law-making powers given to it by the Constitution, including enumerated powers such as those in section 51. A law outside those powers may be invalid. The scope of a power can depend on the law’s purpose and circumstances; a genuine wartime emergency could strengthen a defence-power argument, but would not automatically make every restriction valid. Australia does not have a general constitutional bill of rights. Some protections are express, while the High Court has recognised limited implications from the Constitution’s text and structure. For example, the implied freedom of political communication limits government action that burdens political communication, but it is not a personal right to say anything without restriction.
