International Litigation Partners Pte Ltd v Chameleon Mining Nl (Receivers and Managers Appointed)

The High Court of Australia considered an appeal from the Full Court of the Federal Court of Australia concerning a dispute between International Litigation Partners Pte Ltd (ILP) and Chameleon Mining NL (in receivership and liquidation) (Chameleon). The core of the dispute involved the enforceability of a deed of settlement and release, which ILP sought to rely upon to defeat Chameleon's claim for damages arising from alleged breaches of contract and misleading and deceptive conduct. Chameleon, represented by its receivers and managers, argued that the deed was voidable due to duress and undue influence, and that it did not cover the claims being pursued.

The High Court was required to determine whether the deed of settlement and release was valid and enforceable, or whether it was vitiated by duress or undue influence, thereby rendering it voidable. A further issue was whether, even if valid, the deed operated to release the specific claims that Chameleon was seeking to pursue against ILP. The Court also had to consider the principles governing the construction of deeds of release, particularly in circumstances where the parties were sophisticated commercial entities.

The High Court held that the deed of settlement and release was valid and enforceable. The Court found that there was no evidence to support the allegations of duress or undue influence, noting that ILP's conduct, while commercially aggressive, did not amount to illegitimate pressure that vitiated Chameleon's consent. The Court applied established principles of contract law regarding the formation of agreements and the vitiating factors of duress and undue influence, emphasizing the high threshold required to establish such claims, particularly in a commercial context. Furthermore, the Court construed the deed of release broadly, concluding that its language clearly encompassed the claims that Chameleon sought to advance, thereby preventing Chameleon from pursuing those claims.

The High Court allowed the appeal, set aside the orders of the Full Court of the Federal Court, and ordered that Chameleon's originating application be dismissed.
