Modvat credit documentation rules barred credit on depot-issued supplementary invoices; time-limit objection was also sustained.

Modvat credit was confined to documents prescribed by the applicable rules, including a certificate issued under Rule 57E. Supplementary invoices issued by a manufacturer's depot were not recognised as valid documents for passing on differential duty credit, so credit taken on that basis was inadmissible. Because the credit was not availed on the Rule 57E certificate within the stipulated period, the time-limit objection was also sustained. A cited precedent was treated as inapplicable because it did not decide the legality of credit passed through a depot-issued supplementary invoice.

Issues: Whether Modvat credit of differential duty could be denied on the ground that the credit was taken beyond six months from the date of the certificate issued under Rule 57E, where the credit was availed on supplementary invoices issued by the manufacturer's depot.

Analysis: The relevant credit-taking rules prescribed the documents on which Modvat credit could be availed, including a certificate issued under Rule 57E, but they did not recognise supplementary invoices issued by a depot or dealer as prescribed documents for passing on such credit. The invoices issued by the depot for differential duty were therefore not valid documents under the governing rule framework. Since the appellants did not take credit on the basis of the Rule 57E certificate within the stipulated period, the objection that credit was taken beyond time was sustained. The cited precedent was found inapplicable because it did not decide the legality of credit passed on through a depot-issued supplementary invoice.

Conclusion: The denial of Modvat credit was upheld and the appeal failed.

Final Conclusion: Credit was held inadmissible on the basis of depot-issued supplementary invoices, and the order disallowing the credit was affirmed.

Ratio Decidendi: Modvat credit can be availed only on documents prescribed by the applicable rules, and a depot or dealer cannot validly pass on credit through supplementary invoices unless the rules expressly permit it.
