Paxton and Child Support Registrar & Anor

The parties involved in this case were the father, the Child Support Registrar, and the mother who, along with their child, reside in the United States of America. The dispute centred around the father's application for an extension of time to appeal a decision made by the Social Security Appeals Tribunal (SSAT), which had upheld a Child Support Registrar's determination to register an overseas maintenance liability. This decision was made under the Child Support (Registration and Collection) Act 1988 (Cth). The father sought leave to appeal against the Federal Magistrate's dismissal of his application for an extension of time to appeal the SSAT decision, and the Child Support Registrar applied for leave to appeal the Federal Magistrate's decision to dismiss the Registrar's application for costs arising from the father's unsuccessful application for leave to appeal.

The legal issues before the court were whether the father had grounds for leave to appeal the Federal Magistrate's decision, and whether the Child Support Registrar had grounds for leave to appeal the same decision regarding the costs. The court had to determine if the father's grounds for appeal had a reasonable prospect of success and if the Registrar's costs application was justified. Given that appeals from the SSAT are restricted to questions of law and the Federal Magistrate found no error in the SSAT's decision, the court concluded that the father's grounds for appeal had no reasonable prospect of success.

The court dismissed the father's application for leave to appeal and also refused the Child Support Registrar's application for leave to appeal. The court found that the Registrar's application for indemnity costs in relation to the father's unsuccessful application for leave to appeal was reserved, with both parties required to submit written evidence and submissions regarding the costs. The court did not make an order regarding the Registrar's application for costs related to the leave to appeal. All applications in the appeal were dismissed, and no order was made regarding the Registrar's application for costs in respect of the leave to appeal.
