on doing so, £96 deductible from that source of income. The balance is £271. But in respect of property the balance is £7, for the whole £6 must be deducted from the £13 derived from that source, inas- much as the income therefrom is far below £156. Indeed, there is no way here of diminishing the apportioned deduction of £6. Before a start can be made in that direction the income must exceed £156- see the concluding words of (a) and (b). Thus the total is £276, of which £271 should be taxed on the scale appropriate to its source of income, namely, personal exertion, and £7 on the scale appropriate to the other source of income, namely, property.
I answer the questions as follows: (1) No (2) Nothing; (3) (a) £271, and (b) £7.
The assessment in question was for the financial year beginning 1st July 1916, and therefore the Act No. 18 of 1918, sec. 47, protects the assessment in respect of its computation of the deductions on the basis of the income being the income remaining after allowing all deductions under other sections of the previous Acts. But the section does not avail to protect assessments made on wrong prin- ciples under the Act No. 39 of 1916.
Under all the circumstances, as we take a view which does not coincide with that of either of the parties, I think that there should not be any costs.
ISAACS, GAVAN DUFFY AND RICH JJ. This case has been well argued on both sides, and we have arrived at a clear conclusion.
In 1916 the appellant-a person, other than a company, an absentee, or a person without a dependant-had a total taxable income, consisting of £406 from personal exertion and £13 from property. The question is whether under sec. 19 of the Assessment Act as it then stood (for the law is now altered) he was entitled to a double deduction of £156, that is, one of £156 less a prescribed diminution in respect of each source of income, notwithstanding his property income was only £13 in all.
The Commissioner assessed him at £254 for personal exertion, with a tax on that of £4 4s. 5d., and at £9 for property with a tax of 3s. 4d. total tax liability being £4 7s. 9d. In effect, the Commis- sioner finally calculated a deduction of £156, less the personal
