Applicant M41 of 2004 v MIMA & Anor

This matter concerned an application for judicial review before the High Court of Australia, brought by Applicant M41 of 2004 against the Minister for Immigration and Multicultural Affairs (MIMA) and the second respondent. The applicant sought to challenge decisions made concerning their immigration status.

The central legal issues before the High Court were whether the decisions made by the Minister and the delegate were affected by jurisdictional error, and whether the applicant had been denied procedural fairness. Specifically, the court considered whether the Minister had failed to exercise their non-compellable, non-judicially-reviewable power under s 48B of the *Migration Act 1958* (Cth) in a manner that constituted an error of law.

The High Court, comprising Kirby and Callinan JJ, examined the scope of the Minister's powers and the circumstances under which a failure to exercise such a power could be subject to judicial review. Their Honours considered the principles of procedural fairness and the requirements for a lawful exercise of administrative power, particularly in the context of immigration law. The court's reasoning focused on the interpretation of the *Migration Act* and relevant administrative law principles to determine if the applicant's rights had been unlawfully infringed.

The High Court ultimately made orders in favour of the applicant, quashing the decisions under review and remitting the matter for reconsideration according to law.
