for the purpose of computing the chargeable income. Such a system may produce a comparatively lower valuation of the opening stock and the closing stock, thus, showing a comparatively low difference between the two. In a period of rising turnover and rising prices, the system adopted by the assessee, as found by the Tribunal, is apt to diminish the assessment of the taxable profit of a year. The profit of one year is likely to be shifted to another year which is an incorrect method of computing profits and gains for the purpose of assessment. Each year being a self-contained unit, and the taxes of a particular year being payable with reference to the income of that year, as computed in terms of the Act, the method adopted by the assessee has been found to be such that income could not properly be deduced therefrom. It was, therefore, not only the right but the duty of the Assessing Officer to act in exercise of his statutory power, as he has done in the instant case, for determining what, in his opinion, was the correct taxable income. The Tribunal's order, affirming that of the Assessing Officer, was based on findings of fact made on cogent evidence and in accordance with correct principles. The High Court was clearly wrong in interfering with those findings. Accordingly, the judgment of the High Court was to be set aside.”
