Modvat credit on substitute fuel denied, interest upheld on inadmissible credit, and penalty deleted for lack of suppression.

Extra Low Sulphur oil was treated as a substitute for excluded High Speed Diesel, not as a distinct eligible input, so Modvat credit was rightly denied. Once the credit was found inadmissible, interest became payable on the wrongly availed amount, and the demand for interest was sustained. Penalty was not maintainable because the show cause notice was issued beyond the normal limitation period and the record did not show suppression of facts or wilful misstatement, so deletion of penalty was upheld.

Issues: (i) Whether Extra Low Sulphur oil was different from High Speed Diesel for the purpose of availing Modvat credit; (ii) whether interest was chargeable on the Modvat credit denied; (iii) whether penalty could be sustained when the show cause notice was beyond the normal period and there was no allegation of suppression or wilful misstatement.

Issue (i): Whether Extra Low Sulphur oil was different from High Speed Diesel for the purpose of availing Modvat credit.

Analysis: The relevant question was whether the product described as ELS-HSD was a separate commodity from HSD. The Tribunal noted that the material relied upon showed ELS-HSD to be a substitute for HSD and not a different product in substance. Since High Speed Diesel was excluded from Modvat credit eligibility, the mere fact that the fuel was cleaner or of lower sulphur content did not make it a distinct input eligible for credit.

Conclusion: The denial of Modvat credit on Extra Low Sulphur oil was upheld against the assessee.

Issue (ii): Whether interest was chargeable on the Modvat credit denied.

Analysis: Once the credit was found to be inadmissible, the consequential liability to pay interest followed on the amount wrongly availed. The Tribunal accepted that the denial of credit necessarily carried the obligation to pay interest on the amount demanded.

Conclusion: Interest on the disallowed Modvat credit was held chargeable in favour of Revenue.

Issue (iii): Whether penalty could be sustained when the show cause notice was beyond the normal period and there was no allegation of suppression or wilful misstatement.

Analysis: The Tribunal accepted the Commissioner (Appeals)' finding that the show cause notice had not been issued within the normal period of limitation and that the record did not disclose suppression of facts or wilful misstatement. On that basis, interference with the setting aside of penalty was not warranted.

Conclusion: The setting aside of penalty was sustained in favour of the assessee.

Final Conclusion: The assessee's challenge to denial of credit failed, the Revenue succeeded on interest, and the deletion of penalty was maintained.

Ratio Decidendi: A fuel that is merely a substitute for excluded High Speed Diesel is not treated as a different eligible input for Modvat credit, and once inadmissible credit is denied, interest follows as a consequence, while penalty cannot be sustained absent suppression or wilful misstatement within limitation.
