Carroll and Child Support Registrar (Child support)

This matter concerned an application by Mr Carroll for review of decisions made by the Child Support Registrar. The Administrative Appeals Tribunal (AAT) was asked to consider whether it had jurisdiction to review certain decisions and whether Mr Carroll had provided sufficient evidence to warrant a change to the assessment.

The primary legal issues before the Tribunal were whether it could review a decision made by Child Support on 16 February 2021, and whether it could review decisions made on 29 March 2023 to refuse Mr Carroll extensions of time to object to specific aspects of his child support assessment. The Tribunal also considered the merits of Mr Carroll's objections regarding the inclusion of Ms A's adjusted taxable income and the addition of his relevant children to the assessment.

The Tribunal determined that it could not review the 16 February 2021 decision as no objection decision had been made in relation to it. Regarding the 29 March 2023 decisions, the Tribunal found that Mr Carroll had not provided sufficient evidence to satisfy it that he had advised Child Support of his relevant dependent children prior to 25 November 2019, nor that the inclusion of Ms A's adjusted taxable income was incorrect according to the child support formula. Consequently, the Tribunal concluded that the applications for review had no reasonable prospect of success and dismissed them under s 42B(1) of the *Administrative Appeals Tribunal Act 1975* (Cth).
