BJG18 v Minister for Home Affairs

BJG18 sought judicial review of a decision made by the Administrative Appeals Tribunal (AAT). The applicant contended that the AAT had failed to comply with its obligations under sections 424A and 424AA of the relevant Act. Specifically, BJG18 argued that the AAT Member had taken into account irrelevant considerations and based its findings on ambiguous and vague questions. Furthermore, the applicant submitted that the AAT should not have permitted the unilateral intervention of an interpreter, which allegedly obscured evidentiary issues.

The central legal issues before the Court were whether the AAT had committed jurisdictional error by failing to adhere to its statutory obligations, including those concerning the provision of information to the applicant and the manner in which evidence was considered. The Court was required to determine if the AAT Member's reliance on irrelevant considerations and the use of unclear questioning constituted a reviewable error. Additionally, the Court had to assess whether the involvement of the interpreter in the manner described amounted to a breach of procedural fairness or a failure to properly conduct the review.

Egan J found that jurisdictional error was established. The Court reasoned that the AAT Member's conduct, including the consideration of irrelevant material and the reliance on poorly formulated questions, demonstrated a failure to properly exercise the Tribunal's powers. The Court also agreed that the interpreter's intervention had improperly complicated the evidentiary landscape, thereby undermining the fairness and accuracy of the review process. Consequently, the decision of the AAT was quashed.
