Federal Commissioner of Taxation v Weatherly

The Federal Commissioner of Taxation appealed to the High Court of Australia from a decision of the Supreme Court of Victoria concerning the assessability of income derived from the sale of livestock. The taxpayer, Lionel James Weatherly, a pastoralist, was compelled to sell a significant portion of his sheep and cattle due to the sale of a large part of his station property. He sought to deduct the proceeds from the sale of livestock that would not have been sold but for this necessity, or alternatively, the proceeds from livestock ordinarily used for breeding purposes.

The central legal issue before the High Court was the interpretation of section 17 of the *Income Tax Assessment Act 1922-1925*. Specifically, the court had to determine whether the introductory words of subsection 1, which referred to sales "whether on the sale of a business as a going concern or in any other manner for the purpose of discontinuing the business," limited the scope of the section to only those specific circumstances, or if they were merely illustrative. The court also considered the application of subsection 4(a) of section 17, which excluded livestock ordinarily used for breeding purposes from the definition of "trading stock" for the purposes of the section.

A majority of the High Court, comprising Knox C.J., Higgins, Rich, and Starke JJ., held that the generality of section 17(1) was not limited by the parenthetical words. They reasoned that these words were intended to be illustrative rather than restrictive, and that the sale of livestock in this instance fell within the scope of section 17. Consequently, the taxpayer was entitled to the benefit of section 17(4)(a), meaning the proceeds from the sale of breeding stock were not to be treated as assessable income. Isaacs J., dissenting, argued that the parenthetical words were restrictive and that the sale, not being of the entire business or for the purpose of discontinuing it, did not fall within section 17, thus making the proceeds assessable income under other provisions of the Act.

The High Court, by majority, dismissed the Commissioner's appeal, affirming the decision of the Supreme Court of Victoria. The appeal was dismissed with costs.
