Modvat credit must be claimed within a reasonable time where the rules set no express filing limit.

Where the Modvat Rules did not prescribe an express time limit for availing input credit, a reasonable period was read into the scheme. The text states that credit should be taken within a reasonable time after receipt of the inputs, and applies a six-month benchmark for that purpose. On the facts described, credit taken more than two years after receipt of the goods was treated as beyond the reasonable period and therefore not maintainable. The result stated is that Modvat credit claimed after an unreasonable delay could be denied as barred by limitation.

Issues: Whether Modvat credit on inputs could be taken after a substantial delay in the absence of an express time limit in the Rules, and whether the credit claimed beyond a reasonable period was barred.

Analysis: The applicable Modvat scheme required receipt of inputs under the prescribed duty-paying documents, but no specific time limit for availing credit was laid down in the Rules. In the absence of an express period, a reasonable time was read into the scheme. The Court applied a six-month benchmark as the reasonable period for taking credit after receipt of the inputs. Since the assessee took credit more than two years after receipt of the goods, the claim fell outside the reasonable period and could not be sustained.

Conclusion: The assessee was not entitled to the Modvat credit claimed beyond the reasonable period, and the objection of limitation succeeded.

Final Conclusion: The appeal failed because the credit had been availed after an unreasonable delay, so the denial of Modvat credit was upheld.

Ratio Decidendi: Where the rules do not prescribe an express time limit for availing Modvat credit, a reasonable time may be read into the scheme, and credit taken beyond that reasonable period is barred.
