Singh v The Commonwealth

This case concerned a constitutional question brought before the High Court of Australia on a case stated. The plaintiff, Ms Tania Singh, was born in Australia to parents who were citizens of India and considered "aliens" for the purposes of section 51(xix) of the Constitution. Ms Singh herself was not a citizen under the Australian Citizenship Act 1948 (Cth). The central dispute revolved around whether Ms Singh, despite being born in Australia, was an "alien" within the meaning of the Constitution, which would permit her removal from Australia under the Migration Act 1958 (Cth).

The High Court was required to determine two primary legal issues. First, whether Ms Singh, born in Australia to non-citizen parents, qualified as an "alien" for the purposes of the legislative power granted to the Commonwealth Parliament by section 51(xix) of the Constitution. Second, if she were not an alien, whether section 198 of the Migration Act 1958 (Cth) could validly authorise her removal from Australia solely on the basis of her non-citizen status under the Australian Citizenship Act 1948 (Cth).

The Court reasoned that the historical context of section 51(xix) of the Constitution, including the Convention Debates, indicated an intention to grant Parliament a broad power to legislate with respect to aliens, rather than a narrow one. The Court found that the plaintiff's argument, which sought to rely on the Convention Debates to support her claim, was not made out. Despite being born in Australia, the Court concluded that Ms Singh was a citizen of a foreign state and the child of foreign citizens, and therefore an alien within the meaning of section 51(xix). Consequently, the first question in the case stated was answered in the affirmative.

The Court ordered that the first question in the case stated be answered "Yes", and the second question did not arise. The costs of the case stated were ordered to be borne by the plaintiff.
