Reopening of sales tax assessment may follow a later binding ruling, but disputed stock and purchase valuation need fresh scrutiny.

Section 16 of the Tamil Nadu General Sales Tax Act, 1959 was treated as wide enough to permit reopening of a completed assessment where a later judicial pronouncement showed that the original levy had proceeded on an incorrect legal basis. On that footing, raw hides and skins could be brought to tax at the purchase point, and the reopening was upheld as valid. However, the revised assessment could not stand fully because the inclusion of opening stock and the enhanced valuation of local purchases lacked adequate explanation on the record. Those factual components were remitted for fresh consideration after giving the assessee a reasonable opportunity.

Issues: (i) Whether the assessing authority could reopen the completed assessment under section 16 of the Tamil Nadu General Sales Tax Act, 1959 on the basis of a subsequent decision and bring the raw hides and skins to tax at the purchase point. (ii) Whether the revised assessment could be sustained without explanation on the inclusion of opening stock of raw hides and skins and the enhancement in the value of local purchases.

Issue (i): Whether the assessing authority could reopen the completed assessment under section 16 of the Tamil Nadu General Sales Tax Act, 1959 on the basis of a subsequent decision and bring the raw hides and skins to tax at the purchase point.

Analysis: The power under section 16 was wide enough to reopen an assessment for any reason, including where the original assessment had been made on the footing of an earlier legal view that was later displaced by a subsequent judicial pronouncement. Hides and skins being declared goods were taxable at a single point, and the fact that the original assessment had proceeded on the sale of dressed hides and skins did not bar reopening to levy tax at the purchase point on raw hides and skins when the legal position required that approach.

Conclusion: The reopening of assessment was valid and was rightly upheld.

Issue (ii): Whether the revised assessment could be sustained without explanation on the inclusion of opening stock of raw hides and skins and the enhancement in the value of local purchases.

Analysis: The record did not contain a sufficient explanation for the inclusion of opening stocks or for the higher valuation of local purchases. Since these factual objections had not been properly answered, the matter required reconsideration on those limited aspects after giving the assessee a reasonable opportunity.

Conclusion: The assessment was liable to be remitted for fresh consideration on the limited factual issues.

Final Conclusion: The appellate court affirmed the legality of reopening the assessment, but set aside the revised order to the limited extent necessary for fresh determination of the disputed factual components and remanded the matter accordingly.

Ratio Decidendi: A completed sales tax assessment may be reopened where a subsequent binding legal decision shows that the original levy proceeded on an incorrect legal basis, but factual components of the revised assessment must still be supported by explanation and may be remitted for reconsideration if left unanswered.
