Guo and Anor v Minister for Immigration and Anor

The applicants, Mr. and Mrs. Guo, sought judicial review of a decision by the Administrative Appeals Tribunal (AAT) which affirmed the Minister for Immigration's cancellation of Mrs. Guo's Subclass 100 (Spouse) visa. The central dispute concerned whether the AAT had properly considered evidence relating to Mrs. Guo's lawful name change and whether it had correctly applied the relevant regulations when assessing prescribed circumstances for the visa cancellation.

The court was required to determine two primary legal issues. Firstly, whether the AAT erred in law by failing to adequately address the evidence presented by the applicants concerning Mrs. Guo's lawful change of name. Secondly, the court had to consider whether the AAT misconstrued its task when assessing whether prescribed circumstances existed under regulation 2.41(c) of the *Migration Regulations 1994* (Cth), and whether it erred by failing to consider the spouse's evidence in this regard.

Justice Smith found that the AAT had indeed committed jurisdictional error. The Tribunal's decision demonstrated a failure to engage with the evidence of the lawful name change, treating it as a mere assertion rather than a factual matter to be assessed. Furthermore, the AAT's approach to regulation 2.41(c) indicated a misunderstanding of its obligations, particularly in its failure to consider the spouse's evidence, which was crucial for determining the existence of prescribed circumstances. Consequently, the court granted constitutional relief by issuing the necessary writs.
