Modvat credit and limitation on recovery: additional credit was disallowed, while a delayed demand for reversal was time barred.

Modvat credit was held admissible only to the extent expressly permitted by rules 57A, 57G and 57E: no additional credit could be taken where inputs were cleared under bond or where differential duty was paid later, because the rules then contained no enabling provision for enhancement of credit. Recovery of wrongly availed credit under rule 57I, where no separate limitation period was prescribed, was read with section 11A of the Central Excise Act, 1944; on that basis, a demand raised beyond six months was time barred.

Issues: (i) Whether additional Modvat credit could be taken in respect of inputs when duty was paid subsequently by the input manufacturer after an earlier lower-duty payment or after clearance under bond. (ii) Whether the departmental demand for reversal of wrongly availed Modvat credit was barred by limitation under the relevant recovery provision read with section 11A.

Issue (i): Whether additional Modvat credit could be taken in respect of inputs when duty was paid subsequently by the input manufacturer after an earlier lower-duty payment or after clearance under bond.

Analysis: The credit scheme under rules 57A and 57G operated on the basis of duty shown on prescribed duty-paid documents at the time the inputs were received. In the case of inputs received under bond, no duty-paid document accompanied the goods and no initial credit arose. In the case where duty had been paid at a lower rate and the differential duty was paid later, the relevant rules as they stood during the material period did not contain any enabling provision permitting enhancement of credit on account of such subsequent payment. Rule 57E, as then existing, covered only subsequent variation of duty in the manner provided by the rule and did not authorise the assessees to claim additional credit in the absence of such statutory backing.

Conclusion: The claim for additional credit was rejected and the issue was decided against the assessee.

Issue (ii): Whether the departmental demand for reversal of wrongly availed Modvat credit was barred by limitation under the relevant recovery provision read with section 11A.

Analysis: The Bench applied its consistent view that recovery of credit wrongly availed under rule 57I, when no separate time limit was then prescribed, had to be read with section 11A of the Central Excise Act, 1944. On that approach, the demand in question, having been raised beyond six months, was time barred.

Conclusion: The limitation plea succeeded and the demand was held to be barred by time.

Final Conclusion: Both appeals failed. The order under challenge was maintained, with the assessee denied additional credit and the departmental demand set aside as time barred.

Ratio Decidendi: Modvat credit can be claimed only in the manner and to the extent expressly permitted by the governing rules, and where the rules did not then provide for enhancement of credit on subsequent payment of differential duty, such additional credit was not admissible; recovery of wrongly availed credit under rule 57I, where no specific period was prescribed, was subject to the limitation under section 11A.
