Nakagawa (Migration)

The applicant, Nakagawa, sought judicial review of a decision by the Migration Review Tribunal. The Tribunal had determined it had no jurisdiction to consider Nakagawa's further review application, which was lodged on 15 November 2017. This determination was based on the Tribunal's mistaken belief that the matter had previously been the subject of a valid review by the Tribunal.

The central legal issue before the court was whether the Migration Review Tribunal had jurisdiction to consider Nakagawa's further review application. This required the court to determine if the Tribunal's prior decision constituted a valid review of the merits of Nakagawa's case, or if it was merely a preliminary jurisdictional decision.

The court found that the Tribunal's previous decision was not a determination on the merits of the review application, but rather a finding that it lacked jurisdiction. Consequently, the subsequent application was not a "further review" in the sense contemplated by the Tribunal's mistaken belief. However, the court upheld the Tribunal's ultimate conclusion that it lacked jurisdiction, as the review application itself was lodged out of time. The court reasoned that the time limits for lodging a review application were a jurisdictional prerequisite, and failure to comply with these limits meant the Tribunal could not validly consider the application.

The court therefore affirmed the Migration Review Tribunal's decision that it did not have jurisdiction in the matter.
