Thapa v Minister for Home Affairs

In *Thapa v Minister for Home Affairs*, the applicant, Mr Thapa, sought judicial review of a decision by the Administrative Appeals Tribunal (AAT) to refuse his application for a student visa. The Minister for Home Affairs was the respondent. The core of the dispute concerned the lawfulness of the AAT's decision and the applicant's contention that the AAT had committed a jurisdictional error.

The primary legal issue before the Court was whether the applicant had an arguable case of jurisdictional error in the AAT's decision to refuse his student visa application. This involved examining whether the AAT had failed to exercise its jurisdiction or had acted outside its jurisdiction in reaching its conclusion. The Court also considered whether the applicant's interlocutory application to dismiss a show cause notice issued by the Minister had an arguable basis.

Justice Driver found that the applicant had not demonstrated an arguable case of jurisdictional error. The Court reasoned that the AAT had considered the relevant material and applied the correct legal principles in refusing the visa. The applicant's arguments did not disclose a substantial question of law, and therefore, the application for judicial review was dismissed.
