Alcune Pty Limited v Tri-Anta Pty Ltd

Alcune Pty Limited (the appellant) appealed to the High Court of Australia against a decision of the Full Federal Court concerning the interpretation of a settlement agreement. The dispute arose from a prior legal proceeding between Alcune and Tri-Anta Pty Ltd (the respondent), which had been settled by a deed of settlement. Alcune alleged that Tri-Anta had breached this deed by failing to pay certain amounts it was obliged to pay under its terms.

The central legal issue before the High Court was whether the settlement agreement, as embodied in the deed, extinguished Alcune's right to pursue a claim for damages for misleading or deceptive conduct under the *Trade Practices Act 1974* (Cth) that had arisen prior to the execution of the deed. Specifically, the court had to determine the scope of the release and indemnity provisions within the deed and whether they extended to claims of that nature.

Gaudron and McHugh JJ, in their joint judgment, reasoned that the deed of settlement was intended to provide a comprehensive resolution of all disputes between the parties, both known and unknown, that had arisen up to the date of its execution. They applied the principle that clear and unambiguous language is required to effect a release of unknown causes of action, particularly those arising under statute. The court found that the wording of the deed, particularly the phrase "all claims, demands, actions, suits, proceedings and causes of action whatsoever," was sufficiently broad to encompass the claim for misleading or deceptive conduct, even though it may not have been specifically contemplated at the time of settlement. The court emphasised that the purpose of such a settlement deed is to achieve finality.

The appeal was dismissed.
