and 'gains." The appellant did not furnish the return of income required by sec. 30 to be made by all persons "liable to taxation," and the Com missioners treated him as in default, and made an assessment under sec. 39. assessing his income for the year 1903 at £9,000, the whole amount of his share of the purchase money for the mine, and the tax at £225. The Commis sioners then sued him for the amount of the tax SO assessed. The appellant not having appealed from the assessment to the Court of Review in the manner prescribed by sec. 44, the Commissioners relied upon the assessment book as conclusive evidence of their claim, under sec. 67.
Held, (per Griffith C.J. and Barton J.; O'Connor J. dissentiente), that the proceeds of the sale of the mine were capital and not income, and, therefore, that the income of the appellant for 1903 did not exceed £200 and that, inasmuch as the only persons made liable to taxation by sec. 15 are persons whose incomes exceed that amount, the appellant was not bound to furnish a return under sec. 30, and was not in default within the meaning of sec, 39. The assessment by the Commissioners was therefore in excess of their jurisdie- tion, and invalid, and the appellant was not bound to appeal from it to the Court of Review, but was entitled to wait until sued for the tax, and dispute his liability in the action. The assessment is only conclusive as to matters within the jurisdiction of the Commissioners.
Allen v. Sharp, 2 Ex., 352, distinguished. Per O'Connor J. The question whether the purchase money received by the appellant during 1903 was or was not income subject to taxation is immaterial. It would be impossible to effectively apply the provisions of the Act, unless it were construed as conferring upon the Commissioners, subject to appeal, jurisdiction to determine what income is chargeable with the tax, and, by necessary implication, the power to determine whether the income is above or below the amount exempt from taxation. All persons in receipt of income are subject to the jurisdiction of the Commissioners, and may be assessed in respect of that income, and are therefore "liable to taxation," and bound by sec. 30 to send in returns. The appellant was therefore in default, the assessment was valid, and, not being appealed against, was conclusive.

APPEAL from a decision of the Supreme Court of New South Wales.
