Appellate scope under sales tax law cannot be expanded by additional grounds to dispute an unchallenged turnover.

Section 31 of the Tamil Nadu General Sales Tax Act, 1959 confers appellate power to confirm, reduce, enhance, annul, set aside or otherwise dispose of an assessment, but the assessee's appeal remains limited to the relief and turnover challenged in the original memorandum of appeal. The power to enhance assessment does not permit the assessee to introduce, through additional grounds, a wholly new turnover that was not originally put in dispute. A broader appellate reading was rejected as fact-specific and not authority for expanding the scope of the appeal.

Issues: Whether the Appellate Assistant Commissioner had jurisdiction under section 31 of the Tamil Nadu General Sales Tax Act, 1959 to permit additional grounds challenging a turnover not disputed in the original appeal.

Analysis: Section 31 confers a right of appeal in prescribed form and allows the Appellate Assistant Commissioner to confirm, reduce, enhance, annul, set aside, or otherwise dispose of the assessment, but the assessee's challenge remains confined to the relief and disputed turnover set out in the original memorandum of appeal. The power to enhance the assessment does not enlarge the assessee's right to introduce, by way of additional grounds, a wholly new turnover not originally placed in dispute. The decision relied on to support broader appellate latitude was treated as turning on different facts and not as authority for expanding the scope of the appeal itself.

Conclusion: The Appellate Assistant Commissioner had no jurisdiction to allow additional grounds in respect of turnover not disputed in the original appeal.
