Smalling and Child Support Registrar (Child support)

This matter concerned an application by Mr Smalling for an extension of time to seek a review by the Administrative Appeals Tribunal (AAT) of a decision made by the Child Support Registrar. The Registrar had disallowed Mr Smalling's objection to a prior decision that refused to accept his application to reduce his child support liability. The application for review was made significantly outside the statutory 90-day time limit.

The AAT was required to determine whether to grant Mr Smalling an extension of time to lodge his application for review. In doing so, the Tribunal considered the established legal principles for granting such extensions, which involve balancing the need for justice between the parties against the importance of adhering to statutory time limits. The key factors examined included the explanation provided for the delay, the arguable merits of the substantive application, any prejudice to the other party, and relevant public interest considerations.

The Tribunal found that Mr Smalling had not provided a reasonable explanation for the substantial delay in lodging his application, having received the decision letter within the relevant period but failing to apply for review for approximately five months. While the Tribunal considered that the substantive application might not be entirely devoid of merit, particularly if further evidence could be adduced, it was significantly concerned about the potential prejudice to the other party who had been entitled to rely on the original decision. Furthermore, the Tribunal noted the public interest in the timely finalisation of child support matters and the certainty that statutory time limits are intended to provide.

Ultimately, the Tribunal concluded that the interests of justice were best served by refusing the application for an extension of time. The lack of a reasonable explanation for the delay and the potential prejudice to the other party weighed heavily against granting the extension, despite the arguable merits of the substantive application.
