Cox v Deputy Federal Commissioner of Land Tax, Tasmania

This case concerned an appeal by the trustees of the will of John Claude Cox against an amended land tax assessment issued by the Deputy Federal Commissioner of Land Tax for Tasmania. The dispute arose from the Commissioner's refusal to grant a deduction under section 25 of the Land Tax Assessment Act 1910, which applied to life tenants without power to sell. The trustees contended that the testator's widow, who was entitled to occupy the dwelling-house and receive profits from the estate until the eldest son attained 21, qualified as such a life tenant.

The High Court was required to determine two principal legal issues. Firstly, whether the Commissioner was precluded from issuing the amended assessment by reason of prior proceedings where he had conceded the trustees' claim and paid their costs. Secondly, whether the widow, under the terms of the will, was indeed a tenant for life within the meaning of section 25 of the Act.

The Court held that the Commissioner was precluded from re-asserting his claim. This was because the prior appeal, though withdrawn by the trustees following the Commissioner's concession, constituted a settlement of a matter in litigation. The Court reasoned that this compromise, followed by the Commissioner's payment of costs and refund of overpaid tax, operated as an executed agreement binding on the Crown, akin to a compromise of an action for money paid under compulsion. Regarding the second issue, the Court, by majority, found that the widow held an equitable estate for years, not an estate for life, as her entitlement was for a fixed term (maximum 21 years from the younger son's birth) subject to specific prior determinations.

Consequently, the Court answered the first question in the affirmative, finding the Commissioner was precluded from issuing the amended assessment. As the case was concluded by this determination, the Court did not need to definitively rule on the second question for the purpose of the present appeal, though an opinion was expressed that the widow did not qualify as a life tenant under section 25.
