CDX16 v Minister for Immigration

CDX16 (the applicant) sought judicial review of a decision by the Minister for Immigration (the respondent) 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 affirmed on review by the Administrative Appeals Tribunal. The applicant then brought proceedings in the Federal Court of Australia.

The primary 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 approach to the "particular social group" issue. The Court held that the Tribunal had failed to properly consider the evidence presented by the applicant regarding their alleged membership of a particular social group, and had instead applied an overly restrictive interpretation of the concept. The Court reiterated that membership of a particular social group can be based on shared characteristics that are immutable or fundamental to identity, and that the group must be capable of being identified as distinct from the rest of the population. The Tribunal's failure to engage with the evidence in this manner 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.
