M/s Ravi Prakash Refineries (P) Ltd. v. State of Karnataka
Background
The appellant, a manufacturer and trader of refined edible oil and oil-cake, had declared its inter-state sale of Sunflower De-Oiled Cake (SF DOC) as taxable at a concessional 2% rate (supported by 'C' Forms), and the original assessing officer accepted this. A later assessing officer reopened the assessment, taking the view that de-oiled cake was really taxable at 4% and not covered by the 2% concession meant for "oil cake." The first appellate authority and the Karnataka Appellate Tribunal both ruled for the assessee, holding reassessment on a mere "change of opinion" was impermissible and that oil cake and de-oiled cake should be treated alike. The Karnataka High Court reversed this on revision, holding oil cake and de-oiled cake are legally distinct commodities, which the assessee then challenged before the Supreme Court.
Decision Breakdown
The Supreme Court agreed with the High Court on the substantive classification question, holding that the government notification granting the reduced 2% rate specifically named only "oil cake" and not "de-oiled cake," and that an earlier Supreme Court ruling (Agricultural Produce Market Committee v. Biotor Industries) had already treated the two as distinct commercial products, so the "commercial parlance" argument that they should be taxed alike was rejected. However, the Court found that the original assessing officer had already turned his mind to and accepted the applicable tax rate while verifying the 'C' Forms, meaning the later reopening of the assessment was based on an impermissible mere change of opinion, a point the Revenue had never even challenged through the appellate hierarchy. The appeal was therefore allowed in part: the High Court's finding that oil cake and de-oiled cake are different products was upheld, but the assessee retained the benefit of the original (now final) assessment since it could not lawfully have been reopened.
Lesson Learnt
A tax authority cannot reopen a completed assessment simply because a later officer takes a different view of facts and law that were already considered the first time around: "change of opinion" is not a valid ground for reassessment, even if the later view might otherwise have been legally correct on the merits.
