Monagahn and Monagahn (Child support)

This matter concerned an appeal by Ms Monagahn to the Administrative Appeals Tribunal (the Tribunal) regarding decisions made by the Child Support Registrar (CSA) concerning the percentage of care for a child. The dispute arose from the CSA's initial decisions, which Ms Monagahn appealed. Subsequently, the CSA made further decisions on 17 December 2021 (the December Decisions), which allowed Mr Monagahn's objection to a terminating care event and maintained pre-existing care percentages from 1 July 2020 to 1 October 2020. These December Decisions were issued on 9 February 2022, and Ms Monagahn sought a review of these decisions by the Tribunal, in addition to her earlier appeal concerning the October Decisions. The Tribunal heard four related applications contemporaneously.

The primary legal issues before the Tribunal were whether there had been a change to the likely pattern of care for the child, and whether there were special circumstances that prevented an objection from being lodged within the prescribed time. The Tribunal was required to determine the validity of the existing percentage of care determinations and consider the date of effect provisions under the relevant child support legislation.

The Tribunal considered the oral evidence of both Ms Monagahn and Mr Monagahn, as well as extensive documentary material. The Tribunal affirmed the decisions under review, indicating that it found no change to the likely pattern of care that would warrant revocation of existing determinations. Furthermore, the Tribunal found that special circumstances did exist which prevented the objection from being lodged in time, thereby allowing the late objection. The Tribunal's findings meant that the pre-existing care percentages would continue to apply for the period in question.
