Chang v Minister for Immigration

In the Federal Court of Australia, the applicant, Mr. Chang, sought judicial review of a decision made by the Minister for Immigration, Citizenship and Multicultural Affairs. The dispute concerned the Minister's decision to refuse to grant Mr. Chang a visa.

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 of the Minister, in assessing Mr. Chang's application, had failed to consider relevant considerations or had taken into account irrelevant considerations, thereby vitiating the decision-making process.

Judge Raphael found that the delegate had indeed failed to consider a crucial piece of evidence that was relevant to Mr. Chang's visa application. This failure constituted a jurisdictional error because it meant the delegate did not properly exercise the power conferred upon them by the relevant legislation. The Court affirmed the principle that administrative decision-makers must consider all relevant material placed before them when making a decision.

Consequently, the Court ordered that the Minister's decision be set aside and remitted to the Minister for reconsideration according to law.
