CZY18 v Minister for Immigration

The applicants, CZY18 and others, sought judicial review of a decision by the Immigration Assessment Authority (IAA) to refuse their applications for protection visas. The applicants claimed they feared harm if returned to Sri Lanka. Judge Driver of the Federal Circuit and Family Court of Australia considered whether the IAA's decision was affected by jurisdictional error.

The central legal issue before the Court was whether the IAA engaged in irrational reasoning or failed to consider relevant corroborative evidence when it disbelieved the first applicant in critical respects. This required the Court to examine the process by which the IAA reached its findings and whether that process adhered to the requirements of administrative law.

Judge Driver found that the IAA's reasoning contained jurisdictional error. The Court determined that the Authority's approach to assessing the credibility of the first applicant was irrational, particularly in its selective discrediting of certain aspects of the applicant's account without adequate justification. Furthermore, the Court held that the IAA failed to properly consider and weigh corroborative evidence that was before it, which was relevant to the assessment of the applicants' claims. This failure to engage with the evidence in a rational and comprehensive manner constituted a reviewable error.

The Court ordered that the decision of the Immigration Assessment Authority be set aside.
