St George Bank - a Division of Westpac Banking Corporation v Zhang (No 2)

The case involved St George Bank, a division of Westpac Banking Corporation, and Zhang. The dispute centred around the enforceability of a mortgage agreement and the application of promissory estoppel in the context of real property. The matter was heard in the Supreme Court of New South Wales. The bank sought to enforce a mortgage over a property owned by Zhang, while Zhang argued that the bank was estopped from enforcing the mortgage due to representations made by the bank regarding the nature of the security interest.

The court was required to determine whether promissory estoppel could be applied to prevent the bank from enforcing the mortgage and whether the bank had a juridical basis for seeking an order ancillary to the grant of legal or equitable relief. Additionally, the court had to examine the nature of severalty interests and the applicability of section 138 of the Real Property Act 1900. The central issue was whether the bank's representations could estop it from enforcing the mortgage, and if the court could make an order ancillary to the grant of legal or equitable relief.

The court held that promissory estoppel could not be applied to prevent the bank from enforcing the mortgage. The representations made by the bank did not amount to a clear and unequivocal promise that could be relied upon by Zhang. The court further found that there was no juridical basis for the order sought by the bank, as it did not pertain to the grant of legal or equitable relief. The court also concluded that the bank's request for an ancillary order was not supported by the Real Property Act 1900. Consequently, the court dismissed the bank's claims against Zhang.

The court ordered that the bank's claims be dismissed, and Zhang was awarded costs. The decision underscored the importance of clear and unequivocal promises in the application of promissory estoppel and emphasised the limited circumstances under which ancillary orders can be made in real property matters.
