Westfield Shopping Management Pty Ltd v Mastercare Property Services Pty Ltd

Westfield Shopping Management Pty Ltd (Westfield) and Mastercare Property Services Pty Ltd (Mastercare) were parties to a dispute before the New South Wales Court of Appeal. The core of the disagreement concerned the interpretation and enforceability of a deed of release, which Mastercare argued had extinguished Westfield's right to claim damages for alleged breaches of a cleaning services contract. Westfield, however, contended that the deed was voidable due to misleading and deceptive conduct.

The Court of Appeal was required to determine whether the deed of release was valid and binding, or if it could be set aside on the grounds of misleading and deceptive conduct in contravention of section 52 of the Trade Practices Act 1974 (Cth). A key issue was whether Mastercare's conduct in procuring the deed amounted to misleading or deceptive representations about the nature and effect of the document, and if Westfield had relied on these representations to its detriment.

The Court found that Mastercare had engaged in misleading and deceptive conduct by representing to Westfield that the deed of release was a standard document intended to release only specific, identified claims, when in fact it was intended to operate as a comprehensive release of all claims, including those arising from the alleged breaches of the cleaning contract. This misrepresentation induced Westfield to execute the deed. Applying the principles of contract law and statutory consumer protection, the Court held that the deed was voidable at Westfield's election due to the misleading conduct.

Consequently, the Court of Appeal ordered that the appeal be allowed, the judgment of the primary judge be set aside, and that the deed of release be declared void and of no effect. Westfield was therefore entitled to pursue its claim for damages against Mastercare.
