Commissioner of Taxation v Jayasinghe

The High Court of Australia heard an appeal from the Full Court of the Federal Court of Australia concerning the tax liability of Mr Jayasinghe, an Australian resident engaged by the United Nations Office for Project Services (UNOPS) to work in Sudan. The dispute centred on whether Mr Jayasinghe was entitled to an exemption from Australian income tax on the salaries and emoluments he received from UNOPS, pursuant to the *International Organisations (Privileges and Immunities) Act 1963* (Cth) (IOPI Act).

The primary legal issue before the High Court was the proper construction of section 6(1)(d)(i) of the IOPI Act, which provides for the conferral of privileges and immunities, including exemption from taxation on salaries and emoluments, upon a person who "holds an office in an international organisation to which this Act applies". The court was required to determine whether Mr Jayasinghe's engagement as an individual contractor by UNOPS, under an "Individual Contractor Agreement" to perform specific project management tasks, constituted holding an "office" within the meaning of this provision. A secondary issue involved whether the Commissioner of Taxation was bound by Taxation Determination TD 92/153 in light of the circumstances.

The High Court allowed the appeal, setting aside the decision of the Full Federal Court and the Administrative Appeals Tribunal. The Court reasoned that the terms of Mr Jayasinghe's engagement as an individual contractor, which stipulated he was engaged in his individual capacity as an independent contractor, lacked the necessary incidents of holding an "office" for the purposes of the IOPI Act. The Court emphasised that the relationship was one of a contractor providing specialist services for a defined task, rather than an appointment to a position or role within the organisation's structure. Consequently, Mr Jayasinghe was not entitled to the tax exemption provided by section 6(1)(d)(i) of the IOPI Act.
