The Federal Court of Australia, presided over by Justice Collier, dismissed an interlocutory application by Paul Cooper and Paul Appleton as Joint Liquidators of NQ Minerals PLC seeking to amend prior court orders from 18 February 2026. The liquidators invoked the slip rule under r 39.05 of the Federal Court Rules 2011 (Cth) and the Court's inherent jurisdiction to extend time for compliance with a bankruptcy notice issued against Walter Doyle. The Amended Interlocutory Application lodged on 14 April 2026 was dismissed with costs awarded to Mr Doyle, who will have his costs taxed if not otherwise agreed.
