SIHAG v Minister for Immigration

In the Federal Circuit and Family Court of Australia, the applicant, Mr. Sihaag, sought judicial review of a decision made by the Minister for Immigration, Citizenship and Multicultural Affairs. The dispute concerned the Minister's refusal to grant Mr. Sihaag a Partner (Temporary) (Class UK) visa. Mr. Sihaag contended that the delegate's decision to refuse his visa application was affected by jurisdictional error.

The primary legal issue before the Court was whether the delegate erred in law by failing to consider, or adequately consider, the entirety of the evidence presented in support of Mr. Sihaag's visa application, specifically in relation to the genuineness and continuing nature of his relationship with his sponsor. The Court was required to determine if the delegate's assessment of the relationship evidence was so unreasonable that it constituted a jurisdictional error.

Judge Riley found that the delegate's decision-making process contained a jurisdictional error. The delegate's reasons for refusal indicated a failure to grapple with significant portions of the evidence that supported the applicant's claims about the nature and duration of his relationship. This failure meant that the delegate did not undertake the necessary assessment required by the *Migration Regulations 1994* (Cth) and the *Migration Act 1958* (Cth). The Court applied the principles of administrative law concerning the duty to consider all relevant evidence and the standard for assessing reasonableness in administrative decision-making.

The Court ordered that the decision of the Minister be set aside and remitted to the Minister for redetermination according to law.
