Thayananthan v Minister for Immigration and Multicultural Affairs

The appeal in Thayananthan v Minister for Immigration and Multicultural Affairs was heard by the court, where the appellants, a family of ethnic Tamils from Sri Lanka, sought to challenge the validity of their protection visa applications lodged with the Department of Immigration. The appellants aimed to avoid the operation of section 48A of the Migration Act 1958 (Cth), which prevents individuals from making new protection visa applications if they have previously done so. The primary legal issue the court had to address was whether the original applications were invalid and, if so, whether the Tribunal had jurisdiction to review an invalid application. The court also had to consider if the Minister's delegate could make a decision on an invalid application, and if such a decision could be reviewed by the Tribunal.

The court examined the relevant provisions of the Migration Act and the regulations, which required a valid application to be lodged with the Department. The appellants argued that their initial application was invalid as it did not provide sufficient information to be considered complete. They relied on the case of Yilmaz v Minister for Immigration & Multicultural Affairs (2000) 100 FCR 495, where a Full Court had previously considered a similar issue. In Yilmaz, the Full Court held that the application, which left critical questions unanswered, was not valid. However, the court in the present case found itself bound by the decision in Yilmaz and concluded that the appellants' application was valid.

The court further considered the Minister's undertaking that if the Court found the original decision to be invalid, the Minister would treat the original applications as nullities and not rely on section 48A to bar new applications by the appellants. This undertaking was made to facilitate the resolution of all issues the appellants wished to raise. The court ultimately dismissed the appeal, holding that the primary judge's decision was correct, and ordered the appellants to pay the respondent's costs.
