Wu v Ling

The High Court of Australia heard an appeal in *Wu v Ling*. The dispute concerned the interpretation of a settlement agreement entered into by the parties, which had been made an order of the Federal Circuit and Family Court of Australia. The appellant, Ms Wu, sought to enforce certain terms of the settlement agreement, while the respondent, Mr Ling, contended that those terms were not binding.

The central legal issue before the High Court was whether the settlement agreement, as incorporated into a court order, was capable of being set aside or varied on the grounds of alleged misrepresentation or non-disclosure by Mr Ling. Specifically, the court had to determine the legal effect of a court order that incorporates a settlement agreement, and the circumstances under which such an order might be susceptible to challenge.

Gageler and Keane JJ held that a court order made by consent, which incorporates a settlement agreement, is a final and binding order of the court. Such an order can only be set aside or varied in limited circumstances, such as where there has been a fundamental mistake of fact or law, or where the order was obtained by fraud or duress. The court found that the allegations of misrepresentation and non-disclosure raised by Ms Wu did not meet the high threshold required to set aside a consent order. The principles of finality in litigation and the sanctity of court orders were paramount.

The High Court dismissed the appeal, upholding the decision of the Federal Circuit and Family Court.
