Ko v Minister for Immigration

In *Ko v Minister for Immigration*, the applicant, Mr Ko, sought judicial review of the Minister for Immigration's decision to refuse his application for a Protection Visa (Class XA). The Minister's delegate had refused the visa on the grounds that Mr Ko did not meet the criteria for a refugee or a person otherwise entitled to protection under the *Migration Act 1958* (Cth).

The primary legal issue before the Federal Circuit Court was whether the delegate's decision was affected by jurisdictional error. Specifically, the court was required to determine if the delegate had failed to consider relevant evidence or had taken into account irrelevant considerations when assessing Mr Ko's claims for protection, thereby vitiating the decision-making process.

Judge Lucev found that the delegate had failed to adequately consider crucial aspects of Mr Ko's evidence regarding his fear of persecution in his country of origin. The delegate's assessment had overlooked significant details about the nature and extent of the threats Mr Ko faced, and had not properly engaged with the expert evidence presented. This failure to properly consider relevant evidence constituted a jurisdictional error, rendering the delegate's decision invalid. Consequently, the court quashed the Minister's decision.
