Modvat credit requires proof of filing duplicate invoices with the Range Officer; absent compliance, the credit was denied.

Modvat credit was denied because the assessee failed to prove compliance with the mandatory documentary condition of filing duplicate invoice copies with the Range Officer. In the absence of evidence showing that the prescribed duplicates had been submitted, or even the date of such filing, the Original Authority's finding that the documents were not produced was not shown to be erroneous. The denial of Modvat credit was therefore sustained and the demand remained undisturbed.

Issues: Whether Modvat credit was admissible when the appellants failed to establish that the prescribed duplicate copies of invoices had been submitted to the Range Officer.

Analysis: The prescribed documents for availing Modvat credit were the duplicate copies of invoices. The appellants could not produce evidence showing that such duplicate copies had been filed with the competent authority, nor could they indicate the date of such filing. In the absence of proof of compliance with the documentary requirement, the finding of the Original Authority that the duplicate invoices were not submitted was not shown to be erroneous.

Conclusion: Modvat credit was not admissible to the appellants, and the adverse finding was upheld.

Final Conclusion: The challenge to the denial of Modvat credit failed, and the demand confirmed against the appellants remained undisturbed.
