Jiang v Minister for Immigration

In *Jiang v Minister for Immigration*, the applicant, Mr. Jiang, sought judicial review of a decision by the Minister for Immigration to refuse his application for a partner visa. The dispute centred on whether the Minister had properly considered the applicant's claims of a genuine and continuing relationship with his partner, and whether the decision-maker had adequately addressed the evidence provided in support of that claim. The matter came before Dowdy J of the Federal Circuit and Family Court of Australia.

The primary legal issue before the Court was whether the delegate of the Minister had acted unlawfully in refusing the partner visa application. This involved determining whether the delegate had failed to take into account relevant considerations, taken into account irrelevant considerations, or otherwise made a decision that was so unreasonable that no reasonable decision-maker could have reached it. Specifically, the Court had to consider if the delegate had properly assessed the evidence of the genuineness and continuing nature of the relationship between Mr. Jiang and his partner, as required by the *Migration Regulations 1994* (Cth).

Dowdy J reasoned that the delegate's decision-making process contained a critical flaw. The delegate had focused on a perceived lack of specific documentary evidence in certain categories, without adequately weighing the totality of the evidence presented, including statutory declarations and other forms of corroboration, which collectively demonstrated the genuine and continuing nature of the relationship. The Court applied the principles of administrative law, particularly the requirement for a decision-maker to undertake a holistic assessment of all relevant evidence and to provide adequate reasons for their findings. The delegate's failure to properly consider the cumulative effect of the evidence meant that the decision was vitiated by jurisdictional error.

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