R v Federal Commissioner of Taxation; Ex Parte

The parties to this matter were the Federal Commissioner of Taxation and Sir Kelso King, acting as attorney for Jane Hall, an absentee taxpayer. The dispute concerned the Commissioner's refusal to grant a rebate of income tax under section 18 of the *Income Tax Assessment Act 1922-1928*. The Commissioner's refusal was based on the assertion that the application for the rebate was made more than three years after the tax was due and payable, relying on the proviso to section 37(2) of the Act. The matter came before the Full Court of the High Court of Australia.

The central legal issue before the court was whether the time limitation stipulated in the proviso to section 37(2) of the *Income Tax Assessment Act 1922-1928* applied to an application for a rebate of tax under section 18 of the same Act. Specifically, the court had to determine if a claim for a rebate under section 18 constituted an "alteration in an assessment" to which the three-year time bar in section 37(2) would apply, or if it was a distinct entitlement independent of the assessment alteration process.

The court reasoned that the allowance of a rebate under section 18 did not involve an "alteration in an assessment" as contemplated by section 37(2). Section 18 conferred a direct entitlement to a rebate under specific conditions, which involved a comparison of Australian, United Kingdom, and State tax liabilities. This entitlement was distinct from the Commissioner's power under section 37 to make alterations to assessments to ensure completeness and accuracy, which could result in a refund of overpaid tax. The proviso to section 37(2) specifically limited refunds arising from such alterations when the application was made by the taxpayer more than three years after the tax was due. However, the court found that the rebate under section 18 was not a deduction to be made within the assessment process itself, but rather a rebate of tax already assessed and payable. Therefore, the time limitation in section 37(2) did not preclude a taxpayer from claiming a rebate under section 18, even if the claim was made more than three years after the original tax was due.

The Full Court made absolute the rule nisi for a writ of mandamus, ordering that a writ issue directed to the Commissioner of Taxation, requiring him to consider and determine according to law the taxpayer's application for a rebate under section 18 of the *Income Tax Assessment Act 1922-1928*. The Commissioner was ordered to pay the prosecutor's costs.
