George v Federal Commissioner of Taxation

The case involved an appeal by William Fergus George, a dentist, against assessments made by the Deputy Commissioner of Taxation. The dispute concerned amended and original assessments for the income years ended 30 June 1946 and 30 June 1947, respectively. George contended that these assessments were excessive and that the Commissioner had not properly exercised his powers under the Income Tax Assessment Act 1936-1947.

The legal issues before the court were whether the Commissioner was obliged to provide particulars regarding the alleged sources of additional taxable income assessed, and whether the taxpayer was entitled to particulars concerning the specific officer who formed the judgment under section 167 of the Act. A further issue was whether the powers conferred by section 167 were delegable to a deputy commissioner.

The High Court, in dismissing the taxpayer's appeals, reasoned that under section 190 of the Income Tax Assessment Act, the onus of proving an assessment is excessive rests with the taxpayer. Furthermore, section 177(1) establishes that the production of a notice of assessment is conclusive evidence of its due making. The Court held that the taxpayer's request for particulars as to the source of income was not a matter the Commissioner could be compelled to disclose, as the taxpayer bore the burden of disproving the assessment. Regarding the identity of the officer forming the judgment, the Court found this part of the application misconceived, as the Commissioner's case did not require proving who made the assessment, but rather that the assessment was duly made. The Court also considered the delegation of powers under section 167, noting that while the Act allows for delegation of powers and functions, the formation of the requisite opinion or judgment under section 167 was not necessarily delegable in a way that would require the taxpayer to be informed of the specific individual.

The appeals were dismissed with costs.
