SST Consulting Services Pty Ltd v Rieson & Anor

The High Court of Australia considered an appeal from the Supreme Court of New South Wales in a dispute between SST Consulting Services Pty Ltd (the appellant) and Rieson & Anor (the respondents). The core of the dispute concerned the enforceability of a deed of settlement and release, which the respondents sought to set aside on the grounds of misleading and deceptive conduct.

The primary legal issue before the High Court was whether the respondents had established a contravention of section 52 of the Trade Practices Act 1974 (Cth) (now section 18 of the Australian Consumer Law) by the appellant. This involved determining whether the appellant had engaged in conduct that was misleading or deceptive, or likely to mislead or deceive, in connection with the negotiation and execution of the deed of settlement. A further issue was whether, if a contravention was established, the deed of settlement should be set aside.

The High Court found that the conduct of the appellant in representing that it had no further claims against the respondents was not misleading or deceptive. Their Honours reasoned that the appellant's solicitors had made it clear that the appellant reserved its rights in relation to any claims that might arise in the future, and that the deed of settlement was intended to resolve only existing claims. The court applied the principle that conduct is misleading or deceptive if it leads a person into error, and that the respondents had not been led into error by the appellant's representations. The court also considered the nature of a deed of settlement and the importance of certainty in such agreements.

Consequently, the High Court allowed the appeal, set aside the orders of the Supreme Court of New South Wales, and ordered that the respondents' application to set aside the deed of settlement be dismissed.
