Diamant & Ors v Minister for Immigration & Anor

The applicants, Diamant and others, sought judicial review of decisions made by the Minister for Immigration and another party concerning their immigration status. The dispute centred on the lawfulness of the Minister's decisions to refuse to grant certain visas. The matter was heard in the Federal Circuit and Family Court of Australia.

The primary legal issues before the Court were whether the Minister's decisions were affected by jurisdictional error, and if so, whether the Court should grant relief. Specifically, the applicants contended that the delegate of the Minister had failed to consider relevant considerations and had taken into account irrelevant considerations when making the decisions to refuse their visa applications.

Judge Lucev found that the delegate had indeed made jurisdictional error by failing to consider a crucial piece of evidence that was before the delegate at the time of the decision. This failure meant that the delegate had not properly considered the application as required by the relevant legislation. Consequently, the decisions to refuse the visa applications were vitiated by jurisdictional error. The Court made orders setting aside the decisions of the Minister and remitting the applications to the Minister for reconsideration according to law.
