Australian Airlines Limited v Commissioner of Stamp Duties (Qld)

Australian Airlines Limited (the taxpayer) appealed to the High Court of Australia against a decision of the Supreme Court of Queensland concerning the assessment of stamp duty. The dispute arose from the Commissioner of Stamp Duties (Qld) (the Commissioner) assessing stamp duty on a deed of covenant entered into between the taxpayer and its wholly owned subsidiary, Australian National Airlines Holdings Pty Ltd. The Commissioner had assessed duty on the basis that the deed constituted a 'conveyance' or 'transfer' of property, attracting ad valorem duty.

The central legal issue before the High Court was whether the deed of covenant, which provided for the subsidiary to indemnify the taxpayer against certain liabilities and to pay to the taxpayer the amount of any such liabilities, constituted a dutiable instrument under the Stamp Act 1894 (Qld). Specifically, the court had to determine if the deed was a conveyance or transfer of property, or an agreement for sale, within the meaning of the Act.

The High Court, by majority, held that the deed of covenant did not effect a conveyance or transfer of property. The court reasoned that the deed created a personal obligation on the subsidiary to indemnify the taxpayer, rather than transferring any existing property or creating a new proprietary interest. The obligation was contingent and contractual, and the payment of money was to discharge a liability, not to transfer property. The principles applied focused on the nature of the obligation created by the deed, distinguishing between a proprietary transfer and a contractual indemnity.

The appeal was allowed, and the assessment of stamp duty was set aside.
