Re Minister for Immigration and Multicultural Affairs; ex parte Cassim

In *Re Minister for Immigration and Multicultural Affairs; ex parte Cassim*, McHugh J of the High Court of Australia considered an application for constitutional writs and an injunction. The applicant, who had arrived in Australia on a student visa, sought to quash a decision of the Refugee Review Tribunal (the Tribunal) that refused to grant him a protection visa. He also sought orders prohibiting his detention and removal from Australia, and directing the Tribunal to re-hear his application. The applicant's claim for a protection visa was based on allegations of persecution in Sri Lanka, including questioning by police forces and the disappearance of fellow workers.

The central legal issues before the Court concerned whether the Tribunal's decision was vitiated by a denial of natural justice. Specifically, the applicant contended that natural justice was denied by statutory provisions restricting representation and cross-examination, the Tribunal's failure to investigate his claims and supporting documents, the consideration of irrelevant factors in refusing to investigate, the making of findings of fact so unreasonable that no reasonable Tribunal could have reached them, the failure to warn that a document relied upon by the applicant would be relied upon, and a general failure to provide a fair and just mechanism for review or to act according to the substantial justice of the case.

McHugh J reasoned that the applicant's claims of natural justice denial failed. His Honour found no error that attracted the High Court's jurisdiction under s 75(v) of the Constitution. The Court dismissed the application.
