Thanh & Anor v Nguyen Minh Hong

The parties to this appeal were Thanh and Anor (appellants) and Nguyen Minh Hong (respondent). The dispute concerned the interpretation and effect of a deed of settlement and release entered into between the parties. The matter came before the High Court of Australia.

The central legal issue before the High Court was whether the deed of settlement and release operated to extinguish the respondent's claim for damages for breach of contract, notwithstanding that the respondent had not been legally represented at the time of its execution. The court was required to consider the principles of contractual interpretation and the circumstances under which a party might be held to be bound by a settlement agreement, particularly where there are allegations of unconscionability or undue influence.

The High Court held that the deed of settlement and release was binding on the respondent. The court reasoned that the language of the deed was clear and unambiguous, and it plainly evinced an intention to release all claims, including those for breach of contract. The court rejected the argument that the respondent's lack of legal representation at the time of signing the deed rendered it voidable. The judges found no evidence of unconscionable conduct or undue influence on the part of the appellants. The principles applied centred on the ordinary rules of contractual construction, giving effect to the plain meaning of the words used in the deed, and the high threshold required to set aside a formal legal document.

The appeal was dismissed.
