The assessee, the appellant herein, is a registered firm engaged in the business of manufacture and sale of biscuits intended for human consumption. The assessee is a registered dealer under the Act. During the assessment proceedings under the Act for the year 1972-73 the assessee claimed that the turn-over relating to biscuits manufactured and sold by it amounting to Rs. 35,09,920.38 P. was liable to be taxed at two per cent which was the rate prescribed by a notification issued by the State Government for cooked food contending that 'cooked food' :.included 'biscuits' also. The noti· fication relied on was one issued on October 6, 1971 under sub· section (2) of section 3-A of the Act in supersession of an earlier notification dated July 1, 1969. In both the notifications the tax was fixed at two per cent of the turn-over payable at all points of sale in the case of cooked food. The Assistant Commissioner (Tax Assessment) Sales Tax, Kanpur who was the assessing authority rejected the contention of the assessee that cooked food included biscuits also and imposed tax at the rate of three and a half per cent on the turn·over relating to biscuits treating the same ai an unclassified commodity. An appeal filed against the order of the assessing authority before the Deputy Commissioner Sales Tax and a further appeal before the Judge (Appeal) Sales Tax, Lucknow were unsuccessful. The High Court of Allahabad also declined to inter· fere with the said order. This appeal by special leave is filed against the order of the High Court under Article 136 of the Constitution.
