ZHANG v Minister for Immigration

In the Federal Court of Australia, the applicant, Mr. Zhang, sought judicial review of a decision made by the Minister for Immigration. The dispute concerned the Minister's refusal to grant Mr. Zhang a visa, a decision Mr. Zhang contended was unlawful.

The primary legal issue before the Court was whether the Minister's decision to refuse the visa was affected by jurisdictional error. Specifically, the Court was required to consider whether the delegate who made the decision failed to consider relevant considerations or took into account irrelevant considerations, thereby vitiating the decision-making process.

Judge Riley found that the delegate had indeed failed to consider a crucial piece of evidence that was relevant to the assessment of Mr. Zhang's application. This failure constituted a jurisdictional error, as it meant the delegate did not properly exercise the power conferred upon them by the relevant legislation. The Court reasoned that a failure to consider material evidence that bears directly on the criteria for a visa grant renders the decision invalid. Consequently, the Court quashed the Minister's decision.
