Plaintiff M68/2015 v Minister for Immigration and Border Protection & Ors

The applicant, identified as Plaintiff M68/2015, sought judicial review of decisions made by the Minister for Immigration and Border Protection and other respondents concerning the applicant's immigration status. The dispute centred on the lawfulness of the Minister's decision to refuse to grant the applicant a protection visa. The matter came before Nettle J of the High Court of Australia.

The primary legal issue before the Court was whether the Minister's decision to refuse the protection visa was vitiated by jurisdictional error. Specifically, the Court was required to determine if the Minister, in assessing the applicant's claims for protection, had failed to consider relevant considerations or had taken into account irrelevant considerations, thereby rendering the decision invalid. This involved an examination of the scope of the Minister's obligations under the relevant provisions of the *Migration Act 1958* (Cth) and the *Migration Regulations 1994* (Cth).

Nettle J's reasoning focused on the principles of administrative law governing the exercise of statutory power. His Honour applied the established legal principle that a decision-maker must consider all relevant factors and disregard irrelevant ones. The Court found that the Minister's delegate had failed to properly consider the applicant's claims regarding past persecution and the real chance of future persecution, which were central to the assessment of a protection visa application. This failure constituted a jurisdictional error, as it meant the delegate did not exercise the power conferred by the legislation according to its terms.

Consequently, Nettle J made orders quashing the decision of the Minister to refuse the protection visa. The matter was remitted to the Minister for reconsideration according to law.
