Durkan v Commonwealth Bank of Australia Ltd

The New South Wales Court of Appeal heard an appeal by Mr Durkan against a decision of the Supreme Court of New South Wales. The dispute concerned the validity of a mortgage granted by Mr Durkan to the Commonwealth Bank of Australia Ltd.

The primary legal issue before the Court of Appeal was whether the mortgage was void for uncertainty. This uncertainty was alleged to arise from the terms of the mortgage document itself, specifically concerning the description of the secured debt.

The Court of Appeal found that the mortgage was not void for uncertainty. It reasoned that the mortgage document, when read as a whole and in conjunction with the surrounding circumstances, sufficiently identified the secured debt. The principles applied focused on the construction of contractual documents and the requirement for certainty in obligations, holding that a document will not be void for uncertainty if its terms are capable of a reasonable and practical interpretation.

The appeal was dismissed.
