Trenorth Ltd v Mallesons Stephen Jaques

The High Court of Australia considered a dispute between Trenorth Ltd and Mallesons Stephen Jaques concerning the interpretation of a settlement agreement. Trenorth sought to enforce certain terms of the agreement against Mallesons, which resisted the claim.

The central legal issue before the High Court was whether the settlement agreement, which resolved prior litigation between the parties, contained an implied term that Mallesons would not pursue or support any further claims against Trenorth arising from the subject matter of the original dispute. The court also had to determine the proper approach to construing settlement agreements, particularly in light of the parties' intention to achieve finality.

The High Court held that the language of the settlement agreement, viewed in its commercial context and with regard to the objective of achieving finality, did not support the implication of a term preventing Mallesons from supporting further claims. The court emphasised that implied terms are not readily inferred and must be necessary to give business efficacy to the contract or be so obvious that they "go without saying". In this instance, the express terms of the agreement did not necessitate such an implication, and the court declined to imply it.

The High Court dismissed Trenorth's appeal, finding that Mallesons was not in breach of the settlement agreement.
