Gray v Richards (No 4)

The case of Gray v Richards (No 4) involved an application by the plaintiff, Gray, for interest on costs incurred in relation to appeals to the Court of Appeal and High Court. The dispute originated in the Federal Circuit Court, where Gray was the successful party in a proceeding. The Court of Appeal subsequently set aside the costs order made in the Federal Circuit Court, and the High Court later overturned the Court of Appeal’s decision, reinstating the original costs order from the Federal Circuit Court. Gray then sought interest on the costs from the Federal Circuit Court, invoking section 101(4) of the Federal Court of Australia Act 1976.

The central legal issue before the court was whether the Federal Circuit Court retained jurisdiction to order interest on the costs after the Court of Appeal and High Court had both made orders affecting the costs. The court also needed to determine if the application for interest on costs was barred due to alleged delay and whether the Federal Circuit Court could exercise its authority under section 101(4) in light of the High Court's reinstatement of the original costs order. The court had to consider the principles of functus officio and whether the passage of time and the intervening appellate decisions impacted the Federal Circuit Court’s capacity to address the application for interest.

The Federal Circuit Court held that it did retain jurisdiction to order interest on costs under section 101(4) of the Federal Court of Australia Act 1976. The court found that the principle of functus officio did not apply, as the original costs order remained in effect following the High Court’s decision. The court dismissed the argument that the application was untimely, noting that the passage of time and the appellate process did not deprive it of the authority to address the matter. The court ordered that interest be paid on the costs from the date of the original costs order in the Federal Circuit Court, up until the date of satisfaction of those costs.
