RZMW v Minister for Home Affairs

The case of RZMW v Minister for Home Affairs involved the applicant, a citizen of Liberia, seeking judicial review of the decision of the Administrative Appeals Tribunal (AAT) to revoke his Class XB Subclass 200 Refugee visa on character grounds. The primary legal issues were whether the AAT made a jurisdictional error by failing to take into account the best interests of the applicant's minor stepchild and minor sister residing in Australia, and whether the AAT erred by not considering the applicant's mental health when assessing the impediments he might face if removed from Australia. Additionally, the court had to determine whether these errors could be aggregated for the purpose of assessing their materiality.

The court found that the AAT did indeed commit jurisdictional errors by neglecting to consider the best interests of the minor children and the applicant's mental health. The court held that these omissions were significant because they pertained to critical aspects of the applicant's ties to Australia and the potential impediments he might face if deported. The court further concluded that these errors, when considered together, were material enough to affect the outcome of the decision. Consequently, the court allowed the application for judicial review, set aside the AAT's decision, and remitted the matter back to the AAT for reconsideration in accordance with the law.

In its final orders, the court granted the application for judicial review, quashed the AAT's decision made on 11 December 2018, and issued a writ of mandamus requiring a differently constituted Tribunal to determine the applicant's application for review according to law. The applicant was also given liberty to apply in relation to costs within 14 days of the date of these orders.
