Cubillo, Gunner v Commonwealth of Australia

The applicants, Cubillo and Gunner, brought proceedings against the Commonwealth of Australia in the High Court of Australia. The dispute concerned the alleged unlawful detention and mistreatment of the applicants, who were Aboriginal people, during the period of 1957 to 1972. The applicants claimed that their detention and the conditions under which they were held constituted breaches of their constitutional rights and were unlawful at common law.

The High Court was required to determine several significant legal issues. Central to the case was whether the *Australian Constitution* conferred upon the applicants any rights that were infringed by their detention and treatment. Specifically, the Court considered whether the implied freedom of movement, or any other implied constitutional right, protected the applicants from the actions of the executive government. The Court also had to consider the common law principles governing the executive's power to detain individuals and whether those powers had been exceeded.

The majority of the Court, comprising Gleeson CJ and McHugh J, found that the *Australian Constitution* did not confer upon the applicants the rights they asserted. Their Honours held that the constitutional text did not provide a basis for implied rights that would render the executive actions unlawful in the manner alleged. The Court examined the scope of executive power and concluded that, while the common law imposes constraints on executive detention, the specific actions taken in this historical context, as presented to the Court, did not fall outside the bounds of lawful executive authority as understood at the time. The Court's reasoning focused on the interpretation of the Constitution and the historical development of executive power in Australia, ultimately finding no constitutional or common law basis for the applicants' claims.
