BTW15 v Minister for Immigration

The applicant, BTW15, sought judicial review of a decision by the Minister for Immigration to refuse to grant a protection visa. The applicant, who had arrived in Australia by boat, claimed to fear persecution in their country of origin due to their membership of a particular social group. The Minister's delegate had refused the protection visa application, a decision that was subsequently affirmed by the Administrative Appeals Tribunal (AAT). The applicant then brought proceedings in the Federal Court of Australia.

The central legal issue before the Court was whether the AAT had erred in law in its assessment of the applicant's claims regarding membership of a particular social group and the risk of persecution. Specifically, the Court was required to consider whether the AAT had correctly applied the principles established in relevant High Court authorities concerning the definition of a "particular social group" for the purposes of the *Migration Act 1958* (Cth) and the assessment of a well-founded fear of persecution.

Judge Barnes found that the AAT had made an error of law in its interpretation and application of the "particular social group" criterion. The AAT had, in the Court's view, adopted an overly narrow approach to defining the group, failing to adequately consider the evidence presented by the applicant regarding the shared characteristics and social perception of the group in their country of origin. Consequently, the Court concluded that the AAT's decision was vitiated by this legal error.

The Court ordered that the decision of the Administrative Appeals Tribunal be set aside and remitted to the Tribunal for redetermination according to law.
