The result was that from 18th March. 1961 upto 1st April, 1961, a manufacturer having more than two but not more than 24 powerlooms was liable to pay excise duty at the rates set out in the amended noti· fication dated 18th March, 1961 :ind from 1st April, 1961 to 21st April, 1961. the position was that if such a manufacture~. was found to have commenced manufacture of cotton fabrics for the first time on or after -, 1st April, 1961 by acquiring powerlooms from another person who was or had been a licensee of powerloom factory, the rate at which excise duty would be payable by him would be the.next higherrnte specified in the amended notification dated 18th March. 1961. So far as a manufacturer having two or less powerlooms was concerned, he was during the period from 18th March, 1961 upto 1st April, 1961 exempt from excise duty by reason of the notification dated 5th January, 1957, but from 1st April, 1961 to 21st April, 1961 this exemption stood withdrawn if it was found that the manufacturer had commenced manufacture of cotton fabrics for the first time on or after 1st April, 1961 by acquiring powerlooms from another person who was or had been a licensee of powerloom factory ·and in such a case a manufacturer would be liabfo to pay excise duty at the next higher rate prescribed in the amended notification dated 18th March, 1961. This was the position which obtained upto 20th April, 1961, when the second proviso was introduced exempting a manufacturer employing not more than 4 power1ooms and working even in not more thifn one shift from payment of excise duty. Each of the respondents had admittedly not more than 4 powerlooms and it was the case of the respondents that these powerlooms were worked in not more than one shift and hence the respon· dents . claimed that they were exempted from liability for payment of excise duty by virtue of the second proviso. But the answer made on behalf of the Revenue was that the third proviso carved out an exception from the second proviso and since each of the respondents commenced manufacture of cotton fabrics for the first time after 1st April, 1961, he was not exempt from payment of excise duty, but was liable to pay the same at the next higher rate provided in the amended noti· fication dated 18th March, 1961.
