Reversal of input credit can neutralise exempted-value demand, while prior departmental knowledge defeats extended limitation.

Reversal of input credit attributable to exempted clearances is stated to neutralise a subsequent demand for 8%/10% of the exempted value under excise and Cenvat credit rules, so the liability should not survive once the credit has been reversed before the show cause notice. The commentary also notes that the extended limitation period is not available where the use of methanol in the effluent treatment plant was already within departmental knowledge and an earlier notice covered overlapping periods on the same subject matter. On that reasoning, the demand is treated as unsustainable and time-barred.

Issues: (i) Whether the demand of 8%/10% of the value of methanol used in the effluent treatment plant could survive after reversal of input credit; (ii) Whether the demand was barred by limitation.

Issue (i): Whether the demand of 8%/10% of the value of methanol used in the effluent treatment plant could survive after reversal of input credit.

Analysis: The credit taken on the inputs was found to have been reversed before issuance of the show cause notice. On that basis, the requirement to pay 8%/10% of the value of the exempted goods under the relevant excise and cenvat credit provisions did not remain enforceable. The demand was also held to be unsustainable in light of the principle that reversal of credit neutralises such liability.

Conclusion: The demand on this ground was not sustainable and was decided in favour of the assessee.

Issue (ii): Whether the demand was barred by limitation.

Analysis: The use of methanol in the effluent treatment plant was already within the department's knowledge, and an earlier show cause notice covered overlapping periods on the same subject matter. In these circumstances, invocation of the extended period was held to be unjustified.

Conclusion: The demand was time-barred and was decided in favour of the assessee.

Final Conclusion: The impugned order was set aside and the appeal was allowed with consequential reliefs.

Ratio Decidendi: Where the input credit attributable to exempted clearances has already been reversed, a further demand of 8%/10% of the exempted value cannot be sustained, and the extended period cannot be invoked when the material facts were already within the department's knowledge.
