Plaintiff S178/2019 v Minister for Immigration, Citizenship, Migrant Services and Multicultural Affairs & Ors

The case of *Plaintiff S178/2019 v Minister for Immigration, Citizenship, Migrant Services and Multicultural Affairs & Ors* concerned an application for judicial review of a decision made by the Minister for Immigration, Citizenship, Migrant Services and Multicultural Affairs. The applicant, identified as Plaintiff S178/2019, sought to challenge the lawfulness of the Minister's decision. The matter was heard by Bell J in the Federal Court of Australia.

The central legal issue before the Court was whether the Minister's decision to refuse to grant the applicant a visa was affected by jurisdictional error. Specifically, the Court was required to determine if the Minister, in reaching that decision, had failed to exercise a non-discretionary power conferred by the *Migration Act 1958* (Cth) or had otherwise acted outside the scope of the powers granted to the Minister by that Act.

Bell J's reasoning focused on the proper construction of the relevant provisions of the *Migration Act 1958* (Cth) and the *Migration Regulations 1994* (Cth) as they applied to the applicant's circumstances. The Court examined the nature of the power exercised by the Minister and whether the Minister had, in fact, considered all the mandatory criteria required by the legislation before making the decision. The Court applied established principles of administrative law concerning jurisdictional error, including the requirement for a decision-maker to exercise their powers according to law and to consider all relevant matters and disregard irrelevant matters.

The Court found that the Minister's decision was affected by jurisdictional error. Accordingly, Bell J made orders quashing the decision of the Minister and remitting the application for a visa to the Minister for reconsideration according to law.
