Hunt Leather Pty Ltd v Transport for NSW [No 2]

High Court exercises discretionary power to vary orders where footnote in written submissions was overlooked — slip rule applied sparingly

[2026] HCA 4 · decided 11 March 2026 · significance 2/5

The High Court unanimously varied its own orders to remit a costs issue to the Court of Appeal, after recognising it had overlooked a footnote in the appellants' written submissions. The decision restates the stringent conditions under which the power to correct an accidental slip or omission will be exercised.

What happened

On 17 December 2025, the High Court allowed appeals in part in proceedings between Hunt Leather Pty Ltd and others and Transport for NSW. The orders made included dismissal with costs of the appeal and cross-appeal in the Court of Appeal of the Supreme Court of New South Wales, upholding the trial judge's substantive orders and the trial judge's rejection of claims concerning recovery of litigation funding costs. Hunt Leather and Ancio Investments had not sought orders for remittal of the question of the costs of the trial in their notices of appeal or in the section of their written submissions dealing with orders sought. However, a footnote in their written submissions noted that a separate application for leave to appeal from the trial judge's costs orders had been brought in the Court of Appeal, and the body of their submissions maintained that the outstanding costs issue should be referred to the Court of Appeal if the trial judge's substantive orders were reinstated. This costs issue was not repeated in oral submissions, was not the subject of an application to amend the notices of appeal, and was not addressed by Transport for NSW. In making its orders on 17 December 2025, the Court overlooked the footnote. Hunt Leather and Ancio Investments promptly applied to recall and amend the orders before they were perfected by formal entry.

Issues

  • Whether the High Court has a discretionary power to correct an error or omission in a judgment or order, and what is the source of that power
  • Whether the factors supporting the exercise of the discretionary power to correct an error or omission were present in this case
  • Whether the orders should be varied to remit the costs issue to the Court of Appeal, and what costs order should be made on the correction application

Held

Gageler CJ, Gordon, Edelman, Jagot and Beech-Jones JJjoint

The High Court has at least a discretionary power to correct an error or omission in a judgment or order where the interests of justice so require. The source of that power may be r 3.01.2 of the High Court Rules 2004 (Cth) or the powers incidental and necessary to the exercise of the Court's jurisdiction. [5]

Gageler CJ, Gordon, Edelman, Jagot and Beech-Jones JJjoint

The discretionary power to correct an error or omission is to be exercised sparingly due to the interests of finality, with a heavy burden cast upon the applicant. The strongest factors supporting exercise of the power include: (1) the error or omission is plain or obvious, such as where a matter has been overlooked; (2) the application is promptly made and the orders have not been perfected by formal entry; (3) the application does not seek to re-agitate arguments already considered; and (4) there is no relevant disadvantage to the respondent. [5, 6]

All factors supporting the exercise of the discretionary power were present: the Court had overlooked the footnote in the written submissions; the application was promptly made; the application did not seek to re-agitate arguments already considered; and there was no relevant disadvantage to the respondent. Had the Court adverted to the footnote, the costs issue would have been remitted to the Court of Appeal. [6]

Gageler CJ, Gordon, Edelman, Jagot and Beech-Jones JJjoint

The application was allowed and the orders varied to remit to the Court of Appeal the determination of that aspect of the cross-appeal dealing with the costs of the proceedings below. However, because neither the notices of appeal nor the oral submissions referred to the order now sought, there should be no order as to the costs of the application. [7]

The law it states

  • ratioThe High Court has a discretionary power to correct an error or omission in a judgment or order where the interests of justice so require. This power may derive from r 3.01.2 of the High Court Rules 2004 (Cth) (permitting correction of clerical mistakes or errors arising from accidental slip or omission) or from the broader powers incidental and necessary to the exercise of the Court's jurisdiction. applied [5]

  • ratioThe strongest factors supporting exercise of the discretionary power include: (1) the error or omission is plain or obvious, such as where a matter has been overlooked; (2) the application is promptly made and any relevant orders, although publicly announced, have not been perfected by formal entry; (3) the application is not brought for the purpose of re-agitating arguments already considered by the Court; and (4) there is no relevant disadvantage to the respondent. applied [6]
  • ratioWhere a party did not seek particular orders in its notice of appeal or oral submissions, but the omission from the Court's orders was caused by the Court overlooking a matter raised in written submissions, the appropriate remedy is to vary the orders rather than refuse the application — but the failure to seek the orders in the notice of appeal or oral submissions may result in no costs order on the correction application. applied [2, 3, 7]
  • ratioWhere the High Court on appeal upholds the trial judge's substantive orders but a separate application for leave to appeal from the trial judge's costs orders is pending in the Court of Appeal, the appropriate course is to remit the costs issue to the Court of Appeal for determination rather than for the High Court to determine it. applied [6]

Why it matters

This decision consolidates the established principles governing the High Court's power to recall and amend its own orders before perfection. It confirms that the power will be exercised where the omission results from the Court's own oversight rather than a party's failure to advance an argument. Critically, it also demonstrates a practical consequence for parties who bury important relief in footnotes rather than including it in the notice of appeal and oral submissions: the correction may be granted, but costs of the application will not follow. Practitioners should ensure that all orders sought — including remittal of subsidiary issues such as costs — are expressly included in the notice of appeal and repeated in oral submissions.

Key takeaways

  • Ensure all orders sought on appeal, including remittal of subsidiary issues such as costs, are expressly stated in the notice of appeal and repeated in oral submissions — not merely referenced in footnotes to written submissions.
  • An application to correct an overlooked matter should be made promptly and before orders are perfected by formal entry; delay or perfection may defeat the application.
  • The power to correct is not a vehicle for re-agitation; it is confined to plain or obvious errors or omissions such as matters overlooked by the Court.
  • Failure to seek the order in the notice of appeal or oral submissions may result in no costs order on the correction application, even where the application succeeds.
  • Where the High Court reinstates trial orders but a costs appeal is pending in an intermediate court, the appropriate course is remittal of the costs issue rather than determination by the High Court.
