Re Ruddock & Anor, Ex parte Pylka

In *Re Ruddock & Anor, Ex parte Pylka*, the High Court of Australia considered an application for a writ of prohibition. The applicants, Mr. and Mrs. Pylka, sought to prohibit the Minister for Immigration and Multicultural Affairs and the Department of Immigration and Multicultural Affairs from taking any further steps in relation to a decision made by the Minister under s 501(1) of the *Migration Act 1958* (Cth) to refuse to grant a visa to Mr. Pylka. The Minister's decision was based on the Minister's belief that Mr. Pylka did not pass the character test as defined in s 501(6) of the Act.

The central legal issue before the High Court was whether the Minister's decision to refuse the visa application was vitiated by a failure to afford Mr. Pylka procedural fairness. Specifically, the applicants contended that Mr. Pylka was not given adequate notice of the adverse information that formed the basis of the Minister's belief that he did not pass the character test, nor was he given a sufficient opportunity to respond to that information before the decision was made.

Hayne J, applying the principles of procedural fairness, found that the Minister's decision was indeed invalid. His Honour held that where a decision-maker forms a belief that a person does not pass the character test, and that belief is based on adverse information, the person must be given notice of that information and an opportunity to respond to it. This is a fundamental aspect of procedural fairness, requiring that a person be heard before a decision is made that adversely affects their rights or interests. The Minister's failure to provide Mr. Pylka with adequate notice of the adverse information and an opportunity to respond meant that the decision to refuse the visa was made in breach of the rules of natural justice.

The High Court made absolute the order nisi for a writ of prohibition, quashing the Minister's decision to refuse the visa application.
