O'Shaughnessy v Jwland Group Pty Ltd (Appeal)

In O'Shaughnessy v Jwland Group Pty Ltd, the appellant sought to challenge the decision of the Original Tribunal, which had dismissed her claim for an order under s 14 of the Property Law Act 1974 (Qld) for rectification of a deed of release. The legal dispute centred around the interpretation of the deed and whether it accurately reflected the parties' intentions. The matter was heard in the Queensland Civil and Administrative Tribunal (QCAT), which had dismissed the appeal on the grounds that the appellant had failed to provide evidence of a common mistake or misrepresentation that would warrant rectification of the deed.

The central legal issue before the court was how to properly construe the deed of release in light of the principles established in relevant case law, particularly Electricity Generation Corporation v Woodside Energy Ltd and Grant v John Grant & Sons Pty Ltd. The court had to determine whether the appellant could rely on evidence of the parties' subjective intentions to argue for rectification, and if so, under what circumstances such evidence could be considered. The court also needed to clarify the extent to which principles of equity might permit a broader interpretation of the deed beyond what the strict common law would allow.

The Tribunal found that the principles for construing commercial contracts were well-established, focusing on what a reasonable businessperson would have understood the terms to mean, taking into account the language used, the surrounding circumstances, and the commercial purpose of the contract. The Tribunal noted that the Original Tribunal had not fully considered the relevant legal principles, particularly those relating to equitable interpretations of deeds of release. The Tribunal held that the evidence of the parties' subjective intentions, which was not admissible at common law, could be considered under equity if it was relevant to establishing the commercial purpose or objects of the transaction. The Tribunal concluded that the appellant had not demonstrated a common mistake or misrepresentation sufficient to warrant rectification of the deed, but the appeal was upheld on the basis that the Original Tribunal had not properly applied the legal principles in its reasoning.

The Tribunal ordered that the appeals be upheld, the orders of the Original Tribunal be set aside, and the proceedings be remitted to the Original Tribunal to be determined according to law and in accordance with the Tribunal's reasons.
