Vadarlis v MIMA & Ors

The applicants, Mr. and Mrs. Vadarlis, sought judicial review of a decision by the Minister for Immigration and Multicultural Affairs (MIMA) to refuse their application for a Protection Visa. The applicants, who were citizens of Greece, claimed they feared persecution in Greece due to their alleged involvement with a political organisation. The decision under review was made by the Minister, affirming the Refugee Review Tribunal's (RRT) earlier decision to deny the visa. The matter came before the High Court of Australia.

The central legal issue before the High Court was whether the Minister, in exercising the power to refuse a Protection Visa under section 48B of the *Migration Act 1958* (Cth), was bound by the principles of procedural fairness. Specifically, the applicants argued that they were entitled to be informed of adverse information that the Minister intended to rely upon in refusing their visa application and to be given an opportunity to respond to that information.

Gleeson CJ and Hayne J, in a joint judgment, held that the Minister's power under section 48B was not a personal, non-delegable power, but rather an exercise of administrative power. They reasoned that the nature of the power, which involved making a decision about a person's entitlement to remain in Australia based on their fear of persecution, necessitated adherence to the rules of procedural fairness. The Court found that the Minister had failed to provide the applicants with adequate notice of the adverse information and an opportunity to respond, thereby breaching the implied duty of procedural fairness.

The High Court allowed the appeal, quashed the Minister's decision, and remitted the matter to the Minister for reconsideration according to law.
