Ramaswaml, J. The respondent is a private limited company (hereinafter referred to as the asscsscc). The appeal relates to the assessment year 1956·57 for which the previous year is the year ending September 30, 1955. The business of the usessee was to deal with shares and securities. On September 30, 1954 the assessee purchased 11 ,900 shares of Kedarnath Jute Manufacturing Co. Ltd. in two lots, one at the rate of Rs. 9-8-0 per share and U1e other at Rs. 9-4-0 per share from one Beharilal Nathani, Share broker, for a total consideration of Rs. 1,12,575/·. When the assessee purchased the said shares a large amount of dividends was in arrear as the previous owners had not claimed the dividend; declared between 1936 and 1945, although a large part of the dividends on the said shares in respect of the years 1945 to 1954 had been collected by the previous owners of the said shares. A letter addressed by Behari!al Nathani to the assessee bearing the date September 30, 1954 goes to show that the shares had been "sold with arrear dividends". It is adinitted that the dividends which had been declared between the years 1936 and 1945 and were received by the assessee during th~ accounting period amounted to Rs. 43,925/·. The assessee first credited this sum to the profit and loss appropriation account and thereafter transferred the same to a reserve fund in the accounting year ending September 30, 1955. No adjustment was made in 1he share purchase acoount on account of the receipt of dividend. The value of the shares which represented the stock-in-trade Jf the assessee remained the same both in the opening and the clos· ing stocks. Before the Income-tax Officer it was contended on behalf of the assessee that as the arrear dividends pertained to the years 1936 to 1945 the arrear dividend received by the assessee was not \n the nature of income liable to income-tax as it was merely a realisation of capital. The Income-tax Officer rejected the contention of the assessee and treated the amount of arrear di\·idend as the business income of the assessee liable to tax. On appeal by th~ assessee the Appellate Assistant Commissioner of Income-lax examined the question whether the amount of Rs. 43,925/- should be treated as dividend and should therefore, be assessed under s. 12 of the Indian Income.tax Act, 1'922 (hereinafter referred to as the Act) or whether it should be treated as
