The respondent, the assessee company, carried on business of manufacture of textiles. From the year 1949, the respondent started running into losses, resulting in the stoppage of its manufacturing acti· vity from December, 1953. In May, 1956, one of the creditors of the company filed a winding up petition in the High Court. One major creditor of the respondent company, in exercise of its powers under an English mortgage of the iv<ed assets of the company took actual possession of the immovable properties hypothecated to the creditor. The High Court, with the approval of the assessee company and its creditors, evolved a scheme whereunder the business assets of the company were let out on a rent of Rs.2,50,000 per year. The lease was for ten years with option of renewal for another ten years. The intention was that the various creditors wonld be paid out of the lease money. The lease money realised by the company for the assessment years 1957-58 to 1959-60 was assessed by the Income Tax Department under section 10 of the Income Tax Act under the head "Profits and gains of business". But in the subsequent assessment years, the Income Tax Officer held that income from the lease rent was liable to be assessed under the head "Income from other sources" under section 12 of the Act. The assessee company filed an appeal against the order of the Income Tax Officer. The Commissioner upheld the order of the Income Tax Officer. The assessee took the matter to the Income Tax Tribunal. The Tribunal directed the Income Tax Officer t0- treat the income arising out of the letting out of the assets as 'business income'. The matter then went to the High Court. The High Court held that the income derived by the assessee company by way of the lease rent from the letting out of the assets during the years ending 3 lst December, 1959, 3 lst December, 1960, 31st December, 1961and3lst December, 1962, is assessible to tax under the head "profits and gains of business". Aggrieved by the decision of the High Court, the revenue appealed to this Court.
