Excise price lists and limitation: fresh notices cannot reopen settled valuation without statutory grounds for extended assessment.

Approved excise price lists and settled classifications could not be reopened through fresh show cause notices where the issues had already been concluded by statutory adjudication and acted upon. The Court held that writ interference was justified because the notices sought an impermissible re-agitation of settled matters. It further held that the extended limitation under Section 11A was unavailable in the absence of legally sustainable allegations of suppression, wilful misstatement, collusion, or intent to evade duty. On valuation, the established factory-gate sale price under Section 4(1)(a) had to be applied, and resort to the alternative valuation route was not sustainable.

Issues: (i) Whether the impugned show cause notices could be quashed in writ jurisdiction as they sought to reopen matters already concluded by approved price lists and prior adjudications. (ii) Whether the extended period under Section 11A could be invoked in the absence of legally sustainable allegations of suppression, wilful misstatement, or intent to evade duty. (iii) Whether the valuation dispute had to be determined on the basis of factory-gate sales under Section 4(1)(a), rather than by resort to Section 4(2).

Issue (i): Whether the impugned show cause notices could be quashed in writ jurisdiction as they sought to reopen matters already concluded by approved price lists and prior adjudications.

Analysis: The price lists and classification lists had already been processed through the statutory procedure and, on the facts found, had been approved after adjudication. The Court treated such approvals as carrying finality unless reopened by lawful procedure. It held that the Department could not, through fresh notices, repeat the same exercise and re-agitate issues already decided, especially where earlier quasi-judicial orders had been acted upon.

Conclusion: The impugned notices were liable to be interfered with as they attempted an impermissible reopening of settled matters.

Issue (ii): Whether the extended period under Section 11A could be invoked in the absence of legally sustainable allegations of suppression, wilful misstatement, or intent to evade duty.

Analysis: The proviso to Section 11A was treated as exceptional and applicable only where the Department established something more than mere non-payment or procedural lapse. The Court applied the settled principle that deliberate suppression, collusion, or wilful misstatement with intent to evade duty must be specifically made out before the extended period can be used. On the record, the Court found that requirement was not met.

Conclusion: The extended limitation under Section 11A could not be invoked against the assessee.

Issue (iii): Whether the valuation dispute had to be determined on the basis of factory-gate sales under Section 4(1)(a), rather than by resort to Section 4(2).

Analysis: The Court applied the settled excise valuation principle that where factory-gate sales are available and accepted, assessment must proceed on that basis. It rejected the attempt to displace the declared factory price by reopening valuation on the footing of additional charges and related depot transactions, holding that the Department had no lawful basis for ignoring the established factory-gate price structure in the manner sought.

Conclusion: Valuation had to be made on the basis of factory-gate sales under Section 4(1)(a), and the contrary approach was not sustainable.

Final Conclusion: The notices could not survive judicial scrutiny because they sought to reopen concluded excise matters without the requisite statutory foundation, and the proceedings were therefore quashed.

Ratio Decidendi: Approved excise price lists and settled classifications cannot be reopened by a fresh show cause notice unless the Department strictly establishes suppression, wilful misstatement, or other statutory grounds justifying extended limitation and reassessment.
