Plaintiff M28/2014 v Minister for Immigration and Border Protection & Anor

The applicant, identified as Plaintiff M28/2014, sought judicial review of a decision made by the Minister for Immigration and Border Protection and the second respondent. The core of the dispute concerned the lawfulness of the applicant's detention and the validity of the Minister's decision to refuse to grant a protection visa. The matter came before Crennan J of the High Court of Australia.

The central legal issue before the Court was whether the Minister's decision to refuse the applicant's protection visa application was affected by jurisdictional error. This involved an examination of whether the Minister had properly considered all relevant information and applied the correct legal standards in assessing the applicant's claims for protection, particularly in light of the applicant's circumstances and the relevant provisions of the *Migration Act 1958* (Cth).

Crennan J's reasoning focused on the principles of administrative law and the requirements for lawful decision-making by a Minister under the *Migration Act*. The Court considered the scope of the Minister's powers and the obligations imposed upon them when determining protection visa applications. The judgment analysed the evidence before the Minister and whether the decision reached was one that a reasonable decision-maker, properly instructed in the law, could have made. The Court applied established principles regarding jurisdictional error, which occurs when a decision-maker acts outside the limits of their legal authority or fails to exercise their power according to law.

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