Oakes and Child Support Registrar (Child support)

This matter concerned an application by Ms Oakes to the Administrative Appeals Tribunal (AAT) for an extension of time to seek a first review of a decision made by the Child Support Registrar on 15 February 2018. The original decision concerned an objection by Ms Oakes's ex-husband, Mr A, to a child support assessment. Ms Oakes sought to have the AAT consider her application for review, which was lodged on 16 January 2019, significantly outside the statutory 28-day time limit prescribed by section 90 of the Child Support (Registration and Collection) Act 1988 and paragraph 29(1)(d) of the Administrative Appeals Tribunal Act 1975.

The primary legal issue before the AAT was whether to grant Ms Oakes an extension of time to lodge her application for review. In determining this, the Tribunal was required to consider the established legal principles governing such applications, which necessitate a balancing of factors including the explanation for the delay, the merits of the substantive application, any prejudice to the other party, and relevant public interest considerations. The Tribunal noted that the starting position is that proceedings commenced outside a statutory period will generally not be entertained, but that the overarching concern is to ensure justice is done between the parties.

The Tribunal found that Ms Oakes's explanation for the extraordinary delay was not compelling. She stated that she had been misinformed by the Child Support Agency regarding the calculation of her ex-husband's income from his company, and only later learned that the entirety of such income could be considered. However, the Tribunal considered that she had made her own assessment at the time that pursuing the matter further was not worthwhile and had effectively "rested on her rights." While acknowledging that the substantive application might not be entirely devoid of merit, the Tribunal was particularly concerned about the potential prejudice to Mr A, who was entitled to rely on the decision as final since February 2018. Furthermore, the Tribunal highlighted the public interest in timely reviews and the certainty provided by statutory time limits.

Ultimately, the Tribunal concluded that the interests of justice were best served by refusing to grant the extension of time. The exceptionally long delay, coupled with the lack of a satisfactory explanation and the potential prejudice to Mr A, weighed heavily against the application.
