Modvat credit restrictions: excess input credit could not be refunded or freely utilised contrary to notified conditions.

A concessionary input-credit scheme under Rule 57-A operated only within the limits set by the relevant notification, and excess Modvat credit in the RG 23-A account could not be refunded or freely used against other excisable goods where the notification expressly prohibited such treatment. The later Notification No. 5/94-C.E. (N.T.) was treated as continuing the same restriction rather than removing it, so no enforceable right to refund arose from the excess balance. A claim based on legitimate expectation could not override the notified conditions, and the challenge to clause (3) of the second proviso accordingly failed.

Issues: Whether the assessee was entitled to refund or unrestricted utilisation of excess Modvat credit lying in the RG 23-A account, and whether clause (3) of the second proviso to Notification No. 5/94-C.E. (N.T.) was invalid for taking away a claimed benefit.

Analysis: Under Rule 57-A of the Central Excise Rules, 1944, credit of duty on inputs was available only to the extent and subject to the conditions specified by notification. The earlier notification of 1 March 1989 itself had already provided that, for inputs falling under heading 39.04 used in goods under heading 59.03, any excess credit in the RG 23-A account would not be refunded, adjusted, or utilised for any other excisable goods. The later notification of 1 March 1994 did not create that restriction; it continued the same legal position. The assessee therefore had no enforceable right to claim refund of the excess balance, and the plea of legitimate expectation could not override the notification scheme.

Conclusion: The challenge to clause (3) of the second proviso to Notification No. 5/94-C.E. (N.T.) failed, and the assessee was not entitled to refund of the excess credit.

Ratio Decidendi: Where a concessionary input-credit scheme expressly limits refund or further utilisation of excess credit by notification, no vested or enforceable right arises to claim such refund contrary to the notified conditions.
