AHM18 v Minister for Home Affairs

AHM18 (the applicant) sought judicial review of a decision by the Minister for Home Affairs (the respondent) to refuse to grant the applicant a protection visa. The applicant, who had arrived in Australia without a visa, 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. The applicant then brought proceedings in the Federal Court of Australia seeking to quash the Tribunal's decision.

The central legal issue before the Court was whether the Tribunal had erred in law in its assessment of the applicant's claim for protection. Specifically, the Court was required to determine if the Tribunal had correctly applied the legal test for establishing membership of a particular social group for the purposes of the *Migration Act 1958* (Cth) and the Refugee Convention. This involved considering whether the Tribunal had adequately considered the evidence relating to the applicant's alleged membership of a particular social group and whether its findings on this point were reasonably open to it on the evidence.

Judge Street found that the Tribunal had made an error of law in its assessment of the applicant's claim. The Court held that the Tribunal had failed to properly consider the evidence presented by the applicant regarding their membership of a particular social group, and had instead applied an overly restrictive interpretation of the relevant legal principles. The Court emphasised that the assessment of membership of a particular social group requires a holistic and nuanced approach, taking into account all relevant factors and evidence. The Tribunal's failure to do so meant that its decision was not open to it on the evidence.

The Court ordered that the decision of the Administrative Appeals Tribunal be quashed and remitted the matter to the Tribunal to be heard and determined according to law.
