CTA15 v Minister for Immigration and Border Protection & Anor

The proceeding before the High Court of Australia involved CTA15, the applicant, seeking orders in the nature of prohibition and certiorari against the Minister for Immigration and Border Protection and the Administrative Appeals Tribunal. CTA15 sought to prevent the Minister from acting on a Tribunal decision of 10 August 2015, which affirmed a delegate's refusal of CTA15's protection visa application. CTA15 also sought to quash the Tribunal's decision and have the matter remitted for redetermination. CTA15, a citizen of Sri Lanka of Tamil ethnicity, had arrived in Australia illegally in 2012 and had his protection visa application refused by a delegate in April 2014. The Tribunal affirmed this decision, finding no substantial ground to believe CTA15 would suffer significant harm upon removal to Sri Lanka, specifically no real risk of arbitrary deprivation of life, execution of the death penalty, torture, or cruel, inhuman, or degrading treatment or punishment.

The legal issues before the High Court concerned CTA15's application for an order to show cause, which was significantly out of time. Consequently, the primary question was whether CTA15 should be granted an extension of time to bring the application. This, in turn, depended on whether the application for an order to show cause had any arguable basis or prospect of success. CTA15's prior application for judicial review in the Federal Circuit Court had been dismissed by Judge Street on 25 May 2016, who found no satisfactory explanation for the delay and noted the court's lack of power to order a second hearing.

The High Court determined that it would be futile to grant an extension of time. The Court reasoned that CTA15's application for an order to show cause did not identify any arguable basis for the relief sought and therefore had no prospect of success. This conclusion was informed by CTA15's own statement in his Federal Circuit Court affidavit, where he declared he was not challenging the Tribunal's decision on its merits but rather seeking another chance to present his case due to providing wrong information. The Court dismissed the application.
