Chief Commissioner of Stamp Duties v Buckle

The Chief Commissioner of Stamp Duties appealed to the High Court of Australia against a decision concerning stamp duty assessed on a supplemental deed altering the destination of a discretionary trust's corpus. The dispute centred on how to value the "unencumbered value of the property conveyed" for the purposes of ad valorem duty under the *Stamp Duties Act 1920* (NSW). The trust property comprised land purchased with loan proceeds, and the Commissioner sought to assess duty on the unencumbered value of the assets, taking into account potential liabilities inherent in the trust deed.

The legal issues before the High Court were twofold: first, how to interpret the phrase "unencumbered value" in section 66(1) of the *Stamp Duties Act 1920* (NSW) in the context of a discretionary trust and its assets; and second, whether a trustee's right of exoneration and recoupment constitutes a beneficial interest in the trust assets or an encumbrance on the interests of beneficiaries that should be disregarded for duty assessment.

The Court considered the meaning of "encumbrances" in the context of property and liabilities, drawing on *Wallace v Love* and *Commissioner of Stamp Duties (NSW) v Perpetual Trustee Co Ltd (Quigley's Case)*. It concluded that "unencumbered value" in section 66(1) refers to security interests, charges, or liabilities that attach to the property itself, rather than general debts or expenses of the trust. The Court clarified that the supplemental deed did not convey the entirety of the trust fund, but rather interests of a lesser nature, the present value of which must reflect the inherent uncertainties and vicissitudes of the discretionary trust structure. The trustee's right of exoneration and recoupment was not considered an encumbrance in the relevant sense for the purpose of duty assessment.

The appeal was dismissed with costs.
