Stewart & Ors v Ackland

Stewart and Ors (the appellants) appealed to the High Court of Australia against the decision of the Full Federal Court, which had affirmed a judgment of the Federal Court. The dispute concerned the interpretation of a deed of settlement and release entered into between the parties, which purported to resolve all claims arising from a prior joint venture agreement. The appellants sought to argue that certain claims were not covered by the release, despite the broad wording of the deed.

The central legal issue before the High Court was whether the release contained in the deed of settlement and release extended to claims that were not specifically contemplated or known to the parties at the time of its execution. The appellants contended that the release should be construed narrowly, applying only to claims that were in existence and known to them at the time the deed was signed. Conversely, the respondents argued for a broad interpretation, asserting that the language of the deed clearly encompassed all present and future claims arising from the joint venture.

Gageler and Keane JJ, in their joint judgment, applied the principles of contractual interpretation, emphasizing that the meaning of a contract is determined by the objective meaning of its words, read in their context and against the background of the factual circumstances known to the parties. They found that the language of the release was unambiguous and comprehensive, clearly intending to extinguish all claims, whether known or unknown, arising from the joint venture. The Court rejected the appellants' submission that the release should be limited to claims that were specifically contemplated, holding that such a limitation would require express words to that effect. The appeal was accordingly dismissed.
