Modvat credit requires dealer registration and fresh prescribed invoices; unregistered or endorsed invoices were not valid documents.

Dealer registration was treated as a mandatory condition for availing Modvat credit, because the amended scheme used registration to prevent fictitious claims and verify movement of excisable goods. Invoices issued by unregistered dealers were therefore not accepted as valid credit documents. The amended rules also replaced the earlier endorsement practice with a requirement for fresh invoices containing prescribed particulars and supporting records, and endorsed invoices after 1-4-1994 were not recognised as valid. The stated principle was that these requirements were substantive safeguards, not mere procedural formalities, and could not be diluted by prior practice or administrative convenience.

Issues: (i) Whether invoices issued by unregistered dealers could be accepted as valid documents for claiming Modvat credit after the introduction of the dealer-registration requirement; and (ii) whether endorsed invoices could be treated as valid documents for claiming Modvat credit after 1-4-1994.

Issue (i): Whether invoices issued by unregistered dealers could be accepted as valid documents for claiming Modvat credit after the introduction of the dealer-registration requirement.

Analysis: The amended Modvat scheme required the dealer issuing the invoice to be registered. The relevant notification and rules were treated as introducing a substantive and mandatory safeguard intended to prevent fictitious and bogus transactions and to ensure transparency in the movement of excisable goods. The later relaxation for dealers who obtained registration by the extended date did not convert the registration requirement into a merely procedural formality. A purchaser claiming credit had to satisfy both the duty-paid nature of the inputs and the registration of the issuing dealer.

Conclusion: Invoices issued by unregistered dealers were not valid documents for claiming Modvat credit.

Issue (ii): Whether endorsed invoices could be treated as valid documents for claiming Modvat credit after 1-4-1994.

Analysis: After the substitution of gate passes by invoices, the rules and notifications did not preserve the earlier facility of endorsement. The new scheme instead required fresh invoices with full prescribed particulars and supporting records, including stock-account maintenance, so that the department could verify the movement and receipt of goods. In the absence of an express provision permitting endorsement, the Tribunal could not imply such a facility on the basis of earlier practice or administrative instructions. The language of the amended rule was held to be clear and mandatory.

Conclusion: Endorsed invoices were not valid documents for claiming Modvat credit after 1-4-1994.

Final Conclusion: The reference was answered against the assessee on both questions of law, and the matter was sent back to the regular Benches for disposal of the appeals on merits.

Ratio Decidendi: Where the statute or notification makes dealer registration and a fresh prescribed invoice a condition for availing Modvat credit, the requirement is mandatory and cannot be diluted by treating endorsed or unregistered-dealer invoices as procedurally sufficient.
