Hossain v Minister for Immigration and Border Protection & Anor

The applicants, Mr. Hossain and others, sought judicial review of decisions made by the Minister for Immigration and Border Protection and the second respondent, the Administrative Appeals Tribunal. The dispute concerned the lawfulness of the Minister's decision to refuse to revoke a mandatory visa cancellation under s 501(3C) of the Migration Act 1958 (Cth). The matter was heard by Gageler and Keane JJ of the High Court of Australia.

The central legal issue before the High Court was whether the Minister, in exercising the power to refuse to revoke a mandatory visa cancellation under s 501(3C), was bound by the implied constitutional limitation that executive power must be exercised in a manner compatible with the continued existence of the federal judicature. Specifically, the applicants argued that the Minister's decision-making process, which involved considering the best interests of the children of the applicants, was vitiated by a failure to give sufficient weight to those interests, thereby infringing the implied constitutional limitation.

The Court held that the Minister's power under s 501(3C) was not subject to the implied constitutional limitation requiring compatibility with the continued existence of the federal judicature. Gageler and Keane JJ reasoned that the power to refuse to revoke a visa cancellation was an exercise of executive power that did not involve the administration of justice or the exercise of judicial power. Therefore, the constitutional limitation, which applies to the exercise of executive power in a way that would impair the federal judicature's capacity to function, was not engaged. The Court found that the Minister's decision was not vitiated by any error of law.

The applications for judicial review were dismissed.
