SZGTU v MIMIA & Anor

The applicants, SZGTU and MIMIA, brought proceedings before the High Court of Australia concerning the interpretation of certain provisions of the *Migration Act 1958* (Cth). The core of the dispute revolved around the lawfulness of decisions made by the Minister for Immigration and Multicultural and Indigenous Affairs (MIMIA) in relation to the applicants' claims for protection visas.

The High Court was required to determine whether the Minister's decisions were vitiated by jurisdictional error. Specifically, the Court considered whether the Minister, in assessing the applicants' claims, had failed to take into account relevant considerations or had taken into account irrelevant considerations, thereby exceeding or misapprehending the scope of the power conferred by the *Migration Act*. The question also arose as to whether the applicants had been denied procedural fairness.

In their joint judgment, Gummow and Heydon JJ analysed the statutory framework governing the Minister's powers and the principles of administrative law. Their Honours emphasised that the Minister's duty was to exercise the power conferred by the *Migration Act* according to law. They found that the Minister's assessment had, in certain respects, failed to properly engage with the evidence and submissions provided by the applicants, leading to a conclusion that jurisdictional error had occurred. The Court applied established principles regarding the scope of administrative decision-making powers and the requirements of procedural fairness.

The High Court ordered that the applications for judicial review be upheld, quashing the decisions of the Minister. The matter was remitted to the Minister for reconsideration according to law.
