Thirikwa v Minister for Immigration & Anor

The applicant, Thirikwa, sought judicial review of a decision by the Minister for Immigration and Border Protection to refuse to grant her a protection visa. The Minister's delegate had refused the application on the basis that the applicant's claims of persecution were not substantiated by sufficient evidence. The matter came before the Federal Circuit and Family Court of Australia.

The primary legal issue before the Court was whether the delegate's decision to refuse the protection visa was affected by jurisdictional error. This involved an examination of whether the delegate had failed to consider relevant evidence or had taken into account irrelevant considerations when assessing the applicant's claims of persecution. Specifically, the Court had to determine if the delegate's assessment of the evidence was so unreasonable that it amounted to a failure to exercise the power conferred by the relevant legislation.

Judge Heffernan found that the delegate had failed to adequately consider crucial aspects of the applicant's evidence, particularly concerning her fear of persecution upon return to her country of origin. The delegate's assessment was found to be superficial and did not engage with the substance of the applicant's claims in a manner required by law. The Court applied the principles of administrative law, emphasizing the obligation of a decision-maker to genuinely consider all relevant evidence and to provide reasons that demonstrate such consideration. The failure to do so constituted a jurisdictional error.

The Court ordered that the decision of the Minister's delegate be set aside and remitted to the Minister for reconsideration according to law.
