Gill v Deputy Child Support Registrar

In *Gill v Deputy Child Support Registrar*, the Full Federal Court of Australia considered an appeal by Mr. Gill against a decision of the Child Support Registrar. The dispute concerned the Registrar's refusal to accept Mr. Gill's objection to a child support assessment made under the *Child Support (Registration and Collections) Act 1988* (Cth). Mr. Gill contended that the assessment was incorrect due to a failure to properly consider his objection.

The central legal issue before the Full Federal Court was whether the Registrar had a duty to consider the substance of Mr. Gill's objection to the child support assessment, or if the Registrar was merely required to follow a prescribed administrative procedure. Specifically, the Court had to determine if the Registrar's actions constituted a failure to exercise a statutory discretion vested in them under the relevant legislation.

The Court reasoned that the Registrar's statutory duty extended beyond mere procedural compliance. It was held that the Registrar was obliged to genuinely consider the grounds of objection raised by Mr. Gill. The Court emphasised that administrative decision-makers must exercise their discretions lawfully and that a failure to consider relevant material or grounds of objection amounts to an error of law. Consequently, the Registrar's refusal to engage with the substance of Mr. Gill's objection was found to be an unlawful exercise of power.

The Full Federal Court allowed the appeal, setting aside the Registrar's decision. The matter was remitted to the Registrar with a direction to reconsider Mr. Gill's objection in accordance with the law.
