Azuko Pty Ltd & Anor v OldDigger Pty Ltd

The High Court of Australia considered a dispute between Azuko Pty Ltd and another party (the appellants) and OldDigger Pty Ltd (the respondent). The core of the disagreement concerned the interpretation and enforceability of a deed of settlement and release, which had been entered into by the parties to resolve prior litigation. The appellants sought to rely on certain provisions within this deed, while the respondent contended that these provisions were either invalid or did not apply in the circumstances.

The central legal issue before the High Court was whether the deed of settlement and release, as executed by the parties, effectively precluded the appellants from pursuing certain claims against the respondent that had arisen subsequent to the settlement. Specifically, the court had to determine the scope and effect of the release contained within the deed, and whether it extended to the particular causes of action the appellants sought to advance. This involved a close examination of the language used in the deed and the surrounding context of its formation.

The High Court's reasoning focused on the principles of contractual interpretation, particularly as applied to deeds of settlement. The Court emphasised that the plain and ordinary meaning of the words used in the deed should be given primary consideration. It found that the language of the release was broad and unambiguous, clearly intending to encompass all claims, known or unknown, that had arisen between the parties up to the date of the deed. Consequently, the Court held that the appellants were bound by the terms of the deed and were therefore prevented from pursuing the claims that had been released. The appeal was dismissed.
