Mohammed v Minister for Immigration, Citizenship, Migrant Services and Multicultural Affairs

This matter concerned an application for judicial review brought by Mohammed against the Minister for Immigration, Citizenship, Migrant Services and Multicultural Affairs. The dispute centred on the scope of the Administrative Appeals Tribunal's (AAT) powers when reviewing certain decisions made under the Migration Act 1958 (Cth). The case was heard by Street J in the Federal Court of Australia.

The primary legal issue before the Court was to determine the extent to which the AAT, when reviewing a Part 5-reviewable decision, could exercise the powers and discretions conferred on the original decision-maker. Specifically, the Court had to consider whether the AAT's review was confined by the grounds upon which the original decision was made, or if it could undertake a broader reconsideration of the applicant's eligibility based on the evidence and submissions before it at the time of the AAT's decision.

Street J reasoned that section 349 of the Migration Act 1958 grants the Tribunal broad powers on review, including the ability to affirm, vary, set aside, or substitute a new decision. His Honour clarified that the Tribunal's task in determining the correct or preferable decision must be connected to the grounds for exercising the statutory power under review, as articulated in the delegate's findings and reasons. However, this connection does not limit the Tribunal to only considering the specific grounds of the original decision. Instead, the Tribunal must make its decision having regard to all relevant evidence, submissions, and the factual context at the time of its own determination. His Honour rejected the applicant's submission that the review was confined to the original decision-maker's task, finding this interpretation to be a misreading of relevant case law. Consequently, the Court found no jurisdictional error in the AAT's approach to the review.
