Heperu Pty Limited & Ors v Perpetual Trustees Australia Ltd

Heperu Pty Limited and others (the appellants) appealed to the High Court of Australia against a decision of the Full Federal Court concerning the interpretation of a mortgage and guarantee. The dispute arose from a loan facility provided by Perpetual Trustees Australia Ltd (the respondent) to a company, which was secured by a mortgage over property owned by the appellants and guaranteed by them. The appellants sought to argue that the mortgage and guarantee were unenforceable due to alleged breaches of the respondent's obligations under the loan agreement and the Corporations Act 2001 (Cth).

The High Court was required to determine whether the appellants could rely on the respondent's alleged breaches of the loan agreement and the Corporations Act as a defence to the enforcement of the mortgage and guarantee. Specifically, the court considered whether the appellants had established a sufficient causal connection between the respondent's conduct and the loss they claimed to have suffered, and whether the terms of the mortgage and guarantee permitted such defences to be raised.

The High Court held that the appellants had failed to establish that the respondent's conduct constituted a breach of the loan agreement that would render the mortgage and guarantee unenforceable. The court found that the terms of the mortgage and guarantee were clear and did not allow for the defences raised by the appellants. Furthermore, the court determined that the appellants had not demonstrated that the respondent's actions were in contravention of the Corporations Act in a manner that would invalidate the securities. The principles applied by the court centred on the construction of contractual documents and the requirements for establishing defences to the enforcement of securities.

The appeal was dismissed.
