STATE OF GUJARAT vs AMI PIGMENTS PVT. LTD. & ORS. ETC.

The Supreme Court addressed the authority of the Commissioner under the Gujarat Sales Tax Act, 1969 to issue a Circular dated 19th February 2001, which was superseded by a 2005 Circular. The Court held that the interpretation of 'raw materials' and 'processing materials' must adhere to the tests established in previous judgments, specifically J.K. Cotton Spinning & Weaving Mills Co. Ltd. and Collector of Central Excise Vs. Ballarpur Industries Ltd. The Court concluded that the Gujarat Sales Tax Act's provisions differ from those of the A.P. General Sales Tax Act, affirming the validity of the 2001 Circular based on the distinct legal framework of Gujarat.
