Johnson v Perez

The High Court of Australia considered a dispute between Johnson and Perez concerning the interpretation and application of certain provisions within the *Migration Act 1958* (Cth). The central issue revolved around the validity of a deportation order made against Mr Perez.

The primary legal question before the Court was whether the Minister for Immigration and Ethnic Affairs had acted lawfully in making the deportation order, specifically in relation to the Minister's discretion under section 502 of the *Migration Act 1958* (Cth) and whether the appellant had been afforded procedural fairness. The Court also had to determine the scope of judicial review available in such circumstances.

The Court's reasoning focused on the proper construction of the statutory provisions governing deportation and the requirements of natural justice. It was held that the Minister's discretion under section 502 was not unfettered and that the decision-making process must adhere to the principles of procedural fairness. The Court analysed the nature of the discretion and the circumstances in which it could be exercised, ultimately finding that the deportation order was invalid due to a failure to provide Mr Perez with adequate notice and an opportunity to be heard.

The High Court allowed the appeal, quashed the deportation order, and remitted the matter to the Minister for reconsideration according to law.
