Pratten v Commonwealth of Australia

In *Pratten v Commonwealth of Australia*, the applicant, Mr Pratten, sought judicial review of a decision by the Commonwealth of Australia to refuse his application for a visa. The dispute concerned the lawfulness of the decision-making process and the interpretation of relevant provisions of the *Migration Act 1958* (Cth). The matter came before Gageler J of the High Court of Australia.

The primary legal issue before the Court was whether the delegate of the Minister for Immigration and Border Protection had failed to consider relevant considerations and had taken into account irrelevant considerations when refusing Mr Pratten's visa application. This involved an examination of the scope of the duty to consider relevant material and the prohibition against considering irrelevant material under administrative law principles, as applied to the specific context of migration decisions.

Gageler J reasoned that the delegate's decision was vitiated by a failure to consider a crucial piece of evidence that was central to Mr Pratten's case. The Court held that the delegate's approach, which effectively disregarded this evidence without adequate justification, amounted to an error of law by failing to take into account a relevant consideration. The legal principle applied was that administrative decision-makers must genuinely consider all relevant material placed before them, and a failure to do so renders the decision unlawful.

The Court made orders quashing the decision of the delegate and remitting the application for a visa to the Minister for reconsideration according to law.
