Kao v Pyramid Building Society (in Liquidation)

The New South Wales Court of Appeal heard an appeal by Mr. Kao against Pyramid Building Society (in liquidation) concerning the validity of a mortgage. Mr. Kao sought to have the mortgage declared void and unenforceable, arguing that it was procured by fraud and undue influence. The Building Society, represented by its liquidator, sought to uphold the mortgage and enforce its security.

The central legal issues before the Court of Appeal were whether the mortgage was voidable due to the alleged fraud and undue influence exerted upon Mr. Kao, and if so, whether the liquidator could still enforce the mortgage despite these vitiating factors. The court also considered the principles of indefeasibility of title under the Torrens system and the circumstances in which a registered mortgage might be set aside.

The Court of Appeal, applying established principles of equity and property law, found that while there was evidence of undue influence and misrepresentation, these factors did not render the mortgage void *ab initio* (from the beginning). Instead, the mortgage was voidable at the election of Mr. Kao. However, the court held that the liquidator, acting on behalf of the Building Society, was a bona fide purchaser for value without notice of the defect in title, and therefore, the principle of indefeasibility protected the Society's registered interest in the mortgage. The court reasoned that the liquidator's position was analogous to that of a bona fide purchaser, and to allow the mortgage to be set aside would undermine the certainty of the Torrens system.

Consequently, the Court of Appeal dismissed Mr. Kao's appeal and affirmed the validity of the mortgage, allowing the liquidator to enforce it.
