During the assessment years 2001-2002 and 20022003, he had effected purchase of paddy from local unregistered dealers for the purposes of milling and conversion to rice, which was subsequently sold. In the assessments that were completed against the petitioner for the said years, the assessing authority levied purchase tax, under Section 5A of the Kerala General Sales Tax Act, on the purchase of paddy from unregistered dealers. Thereafter, the sales turnover of rice sold by the petitioner was also subjected to the levy of sales tax under Section 5 of the Kerala General Sales Tax Act.

In further appeals preferred by the Department before the Appellate Tribunal, the Appellate Tribunal, relying on the decision
