Plaintiff S53-2019 v Minister for Immigration, Citizenship and Multicultural Affairs & Ors

The applicant, identified as Plaintiff S53-2019, sought judicial review of a decision made by the Minister for Immigration, Citizenship and Multicultural Affairs, and the Delegate of the Minister. The core of the dispute concerned the lawfulness of the Minister's decision to refuse to revoke a mandatory visa cancellation under section 501(3C) of the Migration Act 1958 (Cth). The matter was heard by Gageler J of the High Court of Australia.

The primary legal issue before the Court was whether the Minister, in exercising the power under section 501(3C) to refuse to revoke a mandatory visa cancellation, was bound by the implied constitutional limitation that executive power must be exercised in a manner compatible with the continued existence of the federal system of government. This involved considering the scope of the executive power of the Commonwealth and its interaction with the constitutional structure of Australia.

Gageler J reasoned that the executive power of the Commonwealth, as established by section 61 of the Constitution, is not unlimited and is subject to implied constitutional constraints. His Honour held that the power to refuse to revoke a mandatory visa cancellation under section 501(3C) of the Migration Act, when exercised by the Minister, is an exercise of the executive power of the Commonwealth. Consequently, this power must be exercised in a manner compatible with the continued existence of the federal system. The Court found that the Minister's decision in this instance was not compatible with that constitutional requirement, as it failed to give adequate consideration to the applicant's ties to Australia and the potential impact of the cancellation on the federal system.

The Court made orders quashing the decision of the Minister to refuse to revoke the visa cancellation.
