Ett19 v Minister for Immigration, Citizenship, Migrant Services and Multicultural Affairs

The applicants sought judicial review of a decision made by the Migration Review Tribunal. The core of the dispute concerned the Tribunal's findings regarding the applicant's eligibility for permanent residency and citizenship in Malaysia. The applicants contended that the Tribunal's conclusions were legally unreasonable and that the Tribunal failed to properly consider crucial evidence presented to it.

The legal issues before the court were whether the Tribunal committed jurisdictional error by making a legally unreasonable finding of fact regarding the applicant's ability to obtain Malaysian permanent residency and citizenship, and whether the Tribunal failed to make a relevant inquiry into how the applicant would achieve this status. Additionally, the applicants argued that the Tribunal failed to consider, or properly consider, evidence from Malaysian authorities indicating the applicant had no lawful claim to Malaysian citizenship.

The court reasoned that for a factual finding to constitute jurisdictional error, it must be irrational, unreasonable, or lack intelligible justification, and this error must be material, meaning there is a realistic basis to consider the ultimate decision might have differed had the error not occurred. The court found that the country information relied upon by the Tribunal, which suggested the applicant could obtain Malaysian citizenship, was outdated and did not support the Tribunal's finding. Furthermore, the Tribunal's reliance on this information was not adequately justified. However, the court ultimately concluded that the applicants had not established that the Tribunal's decision was affected by any jurisdictional error.

Consequently, the application was dismissed as the decision was considered a privative clause decision. The court indicated it would hear the parties on the matter of costs.
