SZBZS v MIMIA

The applicants, SZBZS and MIMIA, brought proceedings before the High Court of Australia concerning the interpretation of certain provisions of the *Migration Act 1958* (Cth) and the *Administrative Decisions (Judicial Review) Act 1977* (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' applications 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 making the decisions, had failed to take into account relevant considerations or had taken into account irrelevant considerations, thereby exceeding or misconstruing the authority conferred upon him by the relevant legislation. The applicants contended that the Minister's decision-making process was flawed and that the decisions should be quashed on this basis.

In their joint judgment, Gleeson CJ and Gummow J analysed the statutory framework governing the Minister's powers and the principles of administrative law concerning jurisdictional error. The Court emphasised that the Minister's duty was to consider all the information before him that was relevant to the decision-making process as prescribed by the *Migration Act*. They found that the Minister had indeed failed to consider certain crucial information that was relevant to the assessment of the applicants' claims for protection, and that this failure constituted a jurisdictional error. The Court held that the Minister's decisions were therefore unlawful.

The High Court ordered that the decisions of the Minister be quashed.
