Muller v Minister for Immigration, Citizenship and Multicultural Affairs

In the case of Muller v Minister for Immigration, Citizenship and Multicultural Affairs, the applicant, a long-term Australian resident with a history of criminal offences, sought judicial review of the Administrative Appeals Tribunal's (AAT) decision to affirm the Minister's refusal to revoke the cancellation of his visa. The applicant, born in Tonga and having lived in Australia since 1981, was sentenced to prison for a serious assault that occurred in June 2019, leading to the cancellation of his visa under section 501(3A) of the Migration Act 1958 (Cth). He subsequently applied for the revocation of the visa cancellation, which was refused by the Minister and the AAT. The applicant challenged the AAT's decision on several grounds, arguing that the AAT had considered irrelevant factors, failed to provide procedural fairness, and misapplied relevant ministerial directions.

The court had to determine whether the AAT's consideration of costs to taxpayers and the burden on community resources was appropriate, and if these considerations were relevant in the context of the statutory provisions. Additionally, the court examined whether the applicant was denied procedural fairness by not being alerted to these considerations, and whether the AAT had misunderstood or misapplied the ministerial directions. The court also considered if the AAT had applied its own expectations instead of the community's, engaged in "double counting," or made a decision for punitive purposes. Finally, the court assessed whether any errors by the AAT were material.

The court found that the AAT had indeed erred in considering the costs to taxpayers and the burden on community resources, which were irrelevant to the statutory criteria. The applicant had not been given adequate notice of these considerations, denying him procedural fairness. Moreover, the AAT had misapplied the ministerial directions and engaged in "double counting." These errors were material and resulted in a decision that was not in accordance with the law. Consequently, the court allowed the application for judicial review, quashed the AAT's decision, and ordered the Minister to reconsider the applicant's request for revocation of visa cancellation according to law. The court also ordered the Minister to pay the applicant's costs.
