Commissioner of Stamp Duties v Westpac Banking Corporation; Commissioner of Stamp Duties v The Commonwealth of Australia

The High Court of Australia heard applications for special leave to appeal concerning stamp duty assessments. The applicants were the Commissioner of Stamp Duties (in relation to Westpac Banking Corporation) and the Commissioner of Stamp Duties (in relation to the Commonwealth of Australia). The core of the dispute revolved around the interpretation of section 54(1) of the Stamp Act and its application to certain agreements.

The legal issues before the Court were primarily concerned with the meaning and scope of the opening words of section 54(1) of the Stamp Act. Specifically, the Court was asked to determine whether this provision applied to an agreement where the object was the acquisition of property by one party (the purchaser), and the agreement included a promise by the other party to facilitate the transfer of that property from a third party to the purchaser, contingent on certain steps being successful. Furthermore, the Court had to consider whether the provision applied when the purchaser promised to pay a sum representing the value of the property to the other party in consideration for this acquisition.

The Court was informed that the agreements between the Commonwealth and Westpac involved a mechanism whereby the Commonwealth would introduce legislation into Parliament to transfer property owned by the Defence Service Homes Corporation to Westpac. The Commissioner contended that this arrangement fell within the ambit of section 54(1) of the Stamp Act, arguing for a broad interpretation of the provision's opening words. The applicants sought to demonstrate that they had an arguable case on this point, highlighting its fundamental importance to the scheme of the Act and its widespread application across similar legislation in other states.
