Deemed assessment reopening requires statutory grounds of concealment or incorrect return particulars; non-payment alone is insufficient.

Delay in challenging the reopening order was condoned because the assessee had pursued the reassessment and appellate proceedings and showed sufficient cause for not approaching earlier. Reopening of a deemed assessment under the sales tax law was held invalid because the authority relied only on non-payment of turnover tax, whereas the statute required satisfaction of concealment of sales or incorrect turnover particulars. The reopening order was treated as independent and not merged with the reassessment or appellate orders, so the invalid reopening could not support those later orders. The Tribunal's order was set aside and the consequential tax orders were quashed.

Issues: (i) Whether delay in filing the challenge to the reopening order should be condoned. (ii) Whether the reopening of the deemed assessment under the sales tax law was valid, and whether the subsequent reassessment and appellate orders could stand.

Issue (i): Whether delay in filing the challenge to the reopening order should be condoned.

Analysis: The challenge before the Tribunal was directed not only against the reassessment and appellate orders but also against the reopening order. In the factual setting, the assessee had pursued the matter through the reassessment and appeal process, and sufficient cause was shown for not moving earlier against the reopening order. The High Court accepted the explanation for the delay and held that the procedural objection should not defeat the challenge on merits.

Conclusion: Delay was condoned in favour of the assessee.

Issue (ii): Whether the reopening of the deemed assessment under the sales tax law was valid, and whether the subsequent reassessment and appellate orders could stand.

Analysis: A return accompanied by short payment of turnover tax was not treated as invalid merely for that reason, because the statutory scheme provided for payment of balance tax and interest. However, reopening under the provision governing deemed assessment required the authority to be satisfied that the dealer had concealed sales or furnished incorrect turnover particulars. The reopening order rested only on non-payment of turnover tax and not on the statutory grounds of concealment or incorrect disclosure. The court also held that the reopening order was an independent order and did not merge with the reassessment or appellate orders.

Conclusion: The reopening order was invalid, and the reassessment and appellate orders could not survive.

Final Conclusion: The assessee succeeded, the Tribunal's order was set aside, and all consequential tax orders were quashed.

Ratio Decidendi: Reopening of a deemed assessment can be made only on the specific statutory grounds for concealment or incorrect return particulars, and non-payment of tax by itself is not a valid basis for reopening; an independent reopening order does not merge with later reassessment or appellate orders.
