SZFHL v MIMIA & Anor

The applicants, SZFHL and MIMIA, brought proceedings before the High Court of Australia concerning the interpretation and application of the *Migration Act 1958* (Cth). The core of the dispute revolved around the lawfulness of decisions made by the Minister for Immigration and Multicultural and Indigenous Affairs (MIMIA) regarding the cancellation of visas.

The High Court was required to determine whether the Minister's delegate had properly exercised the power to cancel the applicants' visas under s 501(2) of the *Migration Act*. Specifically, the court considered whether the delegate had taken into account irrelevant considerations and failed to take into account relevant considerations when forming the opinion that the applicants did not pass the character test. The central legal question was whether the delegate's decision-making process was vitiated by jurisdictional error.

In their reasoning, Hayne and Crennan JJ applied established principles of administrative law concerning the exercise of statutory power. Their Honours emphasised that for a decision to be lawful, the decision-maker must consider all relevant matters and disregard all irrelevant matters. The court found that the delegate had impermissibly taken into account information that was not before them at the time of the decision and had failed to give adequate weight to submissions made by the applicants. This failure to properly consider the evidence and submissions constituted a jurisdictional error, rendering the visa cancellation decisions invalid.

Consequently, the High Court ordered that the applications for judicial review be upheld, and the decisions of the Minister to cancel the applicants' visas be quashed.
