Limitation under Modvat runs from credit date, and endorsed gate passes may remain valid for duty credit.

For limitation under Rule 57-I, the relevant six-month period is counted from the date of taking credit, not from the date of filing RT-12 returns, so demands may be time-barred if computed otherwise. The note also states that Modvat credit remains admissible on gate passes even where the documents were endorsed more than once and covered part consignments, because such endorsements do not by themselves invalidate a duty-paying document when supported by applicable authority and departmental instructions.

Issues: (i) Whether, for computing limitation under Rule 57-I, the six-month period was to be reckoned from the date of submission of RT-12 returns or from the date of taking credit. (ii) Whether duty credit under the Modvat scheme was admissible on gate passes that had been endorsed more than once and related to part consignments.

Issue (i): Whether, for computing limitation under Rule 57-I, the six-month period was to be reckoned from the date of submission of RT-12 returns or from the date of taking credit.

Analysis: The applicable rule position after amendment was that the relevant period for limitation was to be counted from the date of taking credit, not from the date of submission of RT-12 returns. On that basis, some of the demands would be time-barred if the later date alone were treated as decisive.

Conclusion: The limitation objection was accepted in principle to the extent that the date of taking credit governed the computation.

Issue (ii): Whether duty credit under the Modvat scheme was admissible on gate passes that had been endorsed more than once and related to part consignments.

Analysis: The endorsed gate passes were treated as valid duty-paying documents for Modvat purposes. The reasoning accepted the line of authority and the departmental instructions indicating that multiple endorsements, including where only part consignments were transferred, did not by themselves invalidate the document for credit purposes.

Conclusion: Modvat credit was held admissible to the respondents on the disputed gate passes.

Final Conclusion: The appeal failed and the order allowing Modvat credit to the respondents was sustained.

Ratio Decidendi: For limitation under the relevant Modvat provisions, the decisive date is the date of taking credit, and a gate pass does not cease to be a valid duty-paying document merely because it has been endorsed more than once or pertains to a part consignment, if the governing instructions and applicable authority support its use.
