SZSBX v Minister for Immigration

This matter concerned an appeal to the Federal Court of Australia regarding a decision made by the Administrative Appeals Tribunal (AAT). The applicant, SZSBX, sought judicial review of the AAT's decision, which had affirmed a delegate's decision to refuse a protection visa. The core of the dispute revolved around whether the AAT had committed jurisdictional error by failing to adequately consider the evidence and arguments presented by SZSBX.

The legal issues before the Court were whether the AAT had failed to conduct a review in accordance with the relevant provisions of the Act, and if so, whether this failure constituted jurisdictional error. Specifically, the Court was required to determine the circumstances under which a failure by the AAT to consider evidence or arguments advanced by an applicant would amount to jurisdictional error, thereby invalidating its decision.

The Court reasoned that a failure by the AAT to consider evidence will amount to jurisdictional error if, as a consequence, it cannot fairly be said that the Tribunal's decision was made after considering the evidence and arguments presented by the applicant. This principle is not concerned with whether the AAT would have reached a different conclusion had it considered the evidence, but rather whether the overlooked evidence was "material" – that is, evidence that, had it been considered, could have materially affected the Tribunal's decision. The Court distinguished this from a mere failure to weigh or discuss every piece of evidence, or an errant finding of fact, emphasizing that jurisdictional error arises when the Tribunal fails to embark on or complete its statutory task by not considering claims or evidence that the Act mandates it to consider.
