Marnham and Child Support Registrar (Child support)

The Administrative Appeals Tribunal (AAT) considered the dispute between Marnham and the Child Support Registrar concerning the percentage of care arrangements for a child. The applicant sought to challenge a decision regarding these care percentages.

The primary legal issues before the Tribunal were whether it had jurisdiction to review the decision, given that the care percentages had not changed, and whether the applicant had established special circumstances to permit a late application for review. The Tribunal also had to consider the date of effect of any decision it might make.

The Tribunal affirmed the decision under review, finding that it lacked jurisdiction to make a determination under subsection 95N(2) of the *Child Support (Registration and Collection) Act 1988* because there had been no change to the established care percentages. Furthermore, the Tribunal determined that the applicant had not demonstrated special circumstances that prevented the application for review from being lodged within the prescribed time. Consequently, the Tribunal dismissed the application for review.
