Federal Commissioner of Taxation v Broken Hill Pty Co Ltd

The Federal Commissioner of Taxation (the Commissioner) appealed to the High Court of Australia against a decision of the Supreme Court of New South Wales, which had allowed an appeal by Broken Hill Pty Co Ltd (BHP) against an assessment of income tax. The dispute concerned the deductibility of certain expenditure incurred by BHP in relation to its operations.

The central legal issue before the High Court was whether expenditure incurred by BHP on the acquisition of rights to mine iron ore, and on the exploration and development of those rights, constituted a capital outgoing or a revenue outgoing for the purposes of the *Income Tax Assessment Act 1936* (Cth). Specifically, the court had to determine if this expenditure was deductible under section 51(1) of the Act, which allows for the deduction of outgoings incurred in gaining assessable income, provided they are not of a capital, private, or domestic nature.

The High Court, in a majority decision, held that the expenditure was of a capital nature. The court reasoned that the acquisition of the rights to mine iron ore represented the acquisition of a capital asset, and the subsequent exploration and development expenditure was inextricably linked to the establishment and improvement of that capital asset. The judges applied the established legal principles distinguishing between capital and revenue outgoings, considering factors such as the enduring benefit derived from the expenditure, the nature of the business operations, and the distinction between the "profit-earning process" and the "profit-earning structure." The court found that the expenditure was directed towards securing the enduring advantage of a source of profit, rather than being part of the day-to-day operations of earning profits from an existing source.

The appeal was allowed, and the assessment made by the Commissioner was upheld.
