Modvat credit documentation requirements controlled use of original invoices, and a new loss plea could not be raised later.

Modvat credit required compliance with the prescribed documentary scheme under Rule 52A and Rule 57G of the Central Excise Rules, which generally called for the duplicate invoice. The original invoice could be used only where the duplicate copy was lost in transit and the Assistant Collector was satisfied on that factual basis. Because the assessee did not raise the loss plea before the original adjudicating authority, the Tribunal declined to entertain that new factual contention at the reference stage, and the disallowance of credit was maintained.

Issues: Whether Modvat credit could be claimed on the basis of the original invoice instead of the duplicate copy, and whether the plea that the duplicate copy had been lost in transit could be raised for the first time before the Tribunal.

Analysis: The claim for Modvat credit was examined in the context of Rule 52A and Rule 57G of the Central Excise Rules. The scheme required the duplicate copy of the invoice for credit, while Rule 57G(2A) permitted recourse to the original invoice only if the duplicate copy had been lost in transit and the Assistant Collector was satisfied about that fact. The assessee had not raised the plea of loss of the duplicate copy before the Assistant Commissioner, and the record showed that sufficient was given to produce the duty-paying documents. In these circumstances, the Tribunal correctly refused to entertain a new factual plea at the reference stage.

Conclusion: The disallowance of Modvat credit was upheld and the new plea could not be entertained.

Final Conclusion: No substantial question of law arose from the Tribunal's order, and the reference failed.

Ratio Decidendi: A claim for Modvat credit must satisfy the prescribed documentary requirements, and a factual plea not raised before the original adjudicating authority cannot be introduced later to invoke a conditional exception.
