CYN17 v Minister for Home Affairs & Anor

The applicant, a citizen of Sri Lanka and an unauthorised maritime arrival, sought constitutional or other writs from the High Court of Australia against the Minister for Home Affairs and the Immigration Assessment Authority. The dispute concerned the refusal of the applicant's Safe Haven Enterprise protection visa, a decision affirmed by the Authority and subsequently dismissed by the Federal Circuit Court and the Federal Court of Australia. The applicant's application to the High Court aimed to circumvent a statutory restriction on appeals to that court from the Federal Court's decision.

The High Court was required to determine whether to grant the applicant's application for constitutional or other writs in its original jurisdiction. This involved considering whether the applicant had established an arguable basis for relief, particularly in light of previous judicial decisions and the High Court Rules. A key aspect was whether the applicant's challenge to the Federal Circuit Court's finding of no jurisdictional error in the Authority's decision, and the subsequent Federal Court decision, could be entertained by the High Court in its original jurisdiction, especially when the applicant did not seek to quash the Federal Court's decision or assert jurisdictional error by that court.

The Court dismissed the application under rule 25.09.1 of the High Court Rules 2004 (Cth) as it did not disclose an arguable basis for the relief sought. The Court reasoned that allowing such an application would subvert the established regime of merits review, judicial review, and appeals, and that exceptional circumstances, which were not present, would be required for the High Court to entertain such a challenge in its original jurisdiction. The applicant's previous attempts to have the Authority consider a United Nations Committee against Torture report were found by the Authority and upheld by the Federal Circuit Court and Federal Court to have been correctly assessed as not meeting the criteria for considering "new information" under the Migration Act 1958 (Cth). The applicant was ordered to pay the first defendant's costs.
