Revision cannot reopen a final tax ruling where a separate appeal lay against the advance clarification and earlier findings had concluded the issue.

A statutory clarification under the Karnataka Sales Tax Act could not be challenged in revision where the Act provided a separate appellate remedy to the High Court, and failure to use that remedy left the clarification final. The revisional authority also proceeded independently on the assessment being erroneous and prejudicial to revenue, so the challenge was not available in revision. The document further states that the taxability of canteen supplies of food and drinks had already been conclusively decided in earlier proceedings, with only a limited remand on a different exemption issue. That concluded finding could not be reopened in a later appeal, and the revision failed because no substantial question of law arose.

Issues: (i) whether the challenge to the Advance Ruling Authority's clarification could be entertained in revision under the Karnataka Sales Tax Act, 1957; (ii) whether the question of taxability of food and drinks supplied in the canteen had already attained finality so as to bar re-adjudication.

Issue (i): Whether the challenge to the Advance Ruling Authority's clarification could be entertained in revision under the Karnataka Sales Tax Act, 1957.

Analysis: The statutory scheme provided a specific remedy to question a clarification of the Advance Ruling Authority by way of appeal to the High Court. The assessee did not pursue that remedy and allowed the clarification to attain finality. In those circumstances, the validity or prospective operation of the clarification could not be reopened in revision. The revisional order was also not shown to rest solely on the clarification, as the revisional authority had independently proceeded on the footing that the assessment order was erroneous and prejudicial to revenue.

Conclusion: The challenge to the Advance Ruling Authority's clarification was not entertainable in the revision proceedings and was not available to the assessee.

Issue (ii): Whether the question of taxability of food and drinks supplied in the canteen had already attained finality so as to bar re-adjudication.

Analysis: In the earlier round, the Tribunal had conclusively held that the assessee's canteen sales of food and drinks did not fall within the claimed exemption and were taxable under the Act, while remanding only the limited question of exemption for second sales of bakery items. That determination had attained finality. The later attempt to reopen the same concluded issue in the fresh appeal amounted to re-litigation of a matter already decided, which was impermissible.

Conclusion: The issue of taxability of food and drinks had attained finality and could not be reopened.

Final Conclusion: No substantial question of law arose, and the revision failed in view of the finality of the earlier findings and the availability of a separate statutory remedy against the advance ruling.

Ratio Decidendi: A party cannot invoke revision to challenge a clarification for which the statute provides an independent appellate remedy, and an issue conclusively decided in earlier proceedings cannot be reopened in subsequent proceedings merely because a limited remand was made on another aspect.
