Goldsworthy Mining Ltd v Federal Commissioner of Taxation

Goldsworthy Mining Ltd (the taxpayer) appealed to the High Court of Australia against a decision of the Federal Commissioner of Taxation (the Commissioner) concerning the deductibility of certain expenditure. The dispute centred on whether expenditure incurred by the taxpayer in acquiring rights to mine iron ore in the Pilbara region of Western Australia was deductible under section 122 of the *Income Tax Assessment Act 1936* (Cth) (the Act).

The primary legal issue before Mason J was whether the expenditure constituted "capital expenditure" within the meaning of section 122(1) of the Act, which allowed for the deduction of capital expenditure incurred in the development of a mine. Specifically, the court had to determine if the acquisition of the mining rights was an expenditure of a capital nature, or if it was part of the taxpayer's business operations and therefore deductible as a revenue expense.

Mason J reasoned that the expenditure was of a capital nature. His Honour applied the established principle that expenditure incurred to acquire an asset or advantage of an enduring nature, which forms part of the structure of the business, is capital expenditure. The acquisition of the exclusive right to mine for iron ore in a vast area was considered to be the acquisition of a capital asset, essential for the establishment and operation of the taxpayer's mining venture. This expenditure was not part of the day-to-day running of the business but rather an investment to secure the very foundation of the enterprise.

The appeal was dismissed, with the court finding that the expenditure was not deductible under section 122 of the Act.
