Dep Com of Taxation v Conley

The Commissioner of Taxation (the Commissioner) appealed to the High Court of Australia against a decision of the Federal Court of Australia concerning the deductibility of certain expenses incurred by Mr. Conley. The dispute centred on whether these expenses, related to the acquisition of shares in a company that subsequently became insolvent, were deductible under section 8-1 of the *Income Tax Assessment Act 1997* (Cth) as outgoings incurred in gaining or producing assessable income, or alternatively, as losses or outgoings incurred in carrying on a business for the purpose of gaining assessable income.

The High Court was required to determine whether the Federal Court had erred in finding that Mr. Conley was entitled to a deduction for the capital loss he incurred on the shares. Specifically, the court had to consider whether the expenditure on the shares was sufficiently connected to the derivation of assessable income, or if it was an investment of capital that did not give rise to a deductible loss. The central question was whether the acquisition of shares in a company, which was not Mr. Conley's primary business, could be considered an operation or undertaking entered into for the purpose of producing assessable income, such that a capital loss on those shares would be deductible.

Gleeson CJ and McHugh J, in a joint judgment, held that the Federal Court had erred in its conclusion. Their Honours reasoned that the expenditure on the shares was an investment of capital. While Mr. Conley was engaged in business activities, the acquisition of shares in the company was not an operation or undertaking entered into for the purpose of producing assessable income in the ordinary sense. Instead, it was an investment of capital, and losses arising from such investments, particularly capital losses, are generally not deductible under section 8-1 of the *Income Tax Assessment Act 1997* (Cth). The court distinguished between expenditure incurred in the course of carrying on a business and expenditure incurred as an investment of capital, even if that investment was made with a view to potential future income.

The appeal was allowed, and the orders of the Federal Court were set aside.
