Extended limitation and Modvat credit fail where no suppression is pleaded and unavoidable process loss occurs in manufacture.

The extended limitation period under Section 11A of the Central Excise Act could not be invoked because the notice did not plead suppression, wilful misstatement, fraud, or any equivalent ground, and the record already disclosed the relevant facts; the penalty therefore lacked a legal foundation. Modvat credit also could not be denied on gypsum lost as invisible or technologically unavoidable process loss during cement manufacture, because Rule 57D protects credit where input is consumed in waste, refuse, or by-product arising in the manufacturing process. The commentary states that the demand for the extended period was time-barred, the penalty was unsustainable, and credit could not be denied on that basis.

Issues: (i) Whether the demand and penalty could be sustained by invoking the extended period of limitation under Section 11A of the Central Excise Act. (ii) Whether Modvat credit could be denied on gypsum lost as invisible or unavoidable process loss during manufacture of cement.

Issue (i): Whether the demand and penalty could be sustained by invoking the extended period of limitation under Section 11A of the Central Excise Act.

Analysis: The show cause notice did not allege suppression, wilful misstatement, misrepresentation, fraud, or any equivalent basis for invoking the proviso to Section 11A. The adjudicating authority introduced a new factual basis by treating the loss as having occurred in a kutcha pit, which was not the case pleaded in the notice. Since the material facts were available from the records and returns, the ingredients necessary for the extended period were absent. The foundation for penalty also failed for want of deliberate evasion.

Conclusion: The demand for the extended period was time-barred and the penalty was not sustainable.

Issue (ii): Whether Modvat credit could be denied on gypsum lost as invisible or unavoidable process loss during manufacture of cement.

Analysis: The loss was accepted as arising during the manufacturing process and not as a removable loss outside manufacture. Rule 57D protects credit where part of the input is contained in waste, refuse, or by-product arising during manufacture of the final product. The authority relied on the principle that technologically unavoidable burning or process losses are invisible losses and do not justify denial of credit. On that footing, the department's contrary approach was held to be unsustainable.

Conclusion: Modvat credit could not be denied on account of the invisible process loss of gypsum.

Final Conclusion: The impugned order was set aside, the appeal was allowed, and the cross-objection stood disposed of accordingly.

Ratio Decidendi: Modvat credit cannot be denied for inputs lost as invisible or technologically unavoidable process waste arising during manufacture, and the extended period of limitation cannot be invoked without a pleaded and proved foundation of suppression or wilful misstatement.
