CTS15 v Minister for Immigration

The applicant, CTS15, 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 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 Circuit and Family Court of Australia.

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 consider whether the Tribunal had properly applied the relevant legal principles in determining whether the applicant was a member of a 'particular social group' for the purposes of the *Migration Act 1958* (Cth) and the Refugee Convention. This involved an examination of the Tribunal's findings of fact and its application of the legal test for membership of a particular social group.

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 adequately consider the evidence presented by the applicant regarding their membership of a particular social group and had applied an overly restrictive interpretation of the legal test. The Court reiterated that membership of a particular social group requires a shared characteristic that is immutable or fundamental to the identity of the members, and that the group must be capable of being identified as distinct from the rest of the population. The Tribunal's failure to properly engage with these principles constituted an error of law.

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