Coke oven gas manufacture and notice-based duty demand: duty set aside without a valid show cause notice, with penalty reduced for proportionality.

Coke oven gas cleared from the factory was treated as manufactured excisable goods, with the intervening processing steps regarded as incidental or ancillary to manufacture, so exemption under Notification No. 179/77 was unavailable. However, the duty demand was set aside because the show cause notice did not specifically propose recovery of duty, Rule 10 of the Central Excise Rules, 1944 required a valid notice before demand, and the record did not establish suppression or clandestine removal to invoke the extended limitation period. Penalty was maintainable in principle because the exemption claim had been rejected, but it was reduced substantially as punishment must be proportionate to the gravity of the offence.

Issues: (i) Whether coke oven gas cleared by the assessee was excisable and whether the demand of duty was sustainable in the absence of a show cause notice specifically proposing recovery of duty and within limitation; (ii) whether the penalty imposed was justified or excessive.

Issue (i): Whether coke oven gas cleared by the assessee was excisable and whether the demand of duty was sustainable in the absence of a show cause notice specifically proposing recovery of duty and within limitation.

Analysis: The production chain for coke oven gas involved a series of processes beginning with charging of coke into the oven and continuing through separation of by-products such as benzene, naphthalene and sulphate of ammonia, with electricity being used at various stages. The gas ultimately cleared from the factory was held to be different from the initial gas released during carbonisation, and the intervening operations were treated as incidental or ancillary to manufacture. At the same time, the notice issued to the assessee was found to contain no specific proposal for recovery of duty, whereas Rule 10 of the Central Excise Rules, 1944 required a notice before any duty demand could be raised. The record also did not establish suppression of facts or clandestine removal so as to attract the extended period.

Conclusion: The gas was held to be manufactured and not entitled to exemption under Notification No. 179/77, but the duty demand was quashed as no valid duty demand had been proposed in the show cause notice and the longer limitation period was inapplicable; the assessee succeeded on this issue.

Issue (ii): Whether the penalty imposed was justified or excessive.

Analysis: The assessee had claimed exemption in its classification lists, but the department had rejected the claim, and the Tribunal held that the assessee ought not to have ignored that rejection. At the same time, the quantum of penalty had to bear a reasonable relation to the gravity of the offence. Applying the principle that punishment must be proportionate, the penalty was examined on merits and found to be excessive in the original amount.

Conclusion: The imposition of penalty was upheld in principle, but the quantum was reduced from Rs. 6 lakhs to Rs. 50,000, with relief granted to the assessee to that extent.

Final Conclusion: The appeal succeeded to the extent that the duty demand was set aside and the penalty was substantially reduced, leaving only a reduced penalty liability on the assessee.

Ratio Decidendi: A duty demand under the Central Excise regime cannot be sustained unless a proper show cause notice proposing recovery of duty is issued, and where suppression or clandestine removal is not established, the normal limitation period applies; penalty, though maintainable, must be proportionate to the gravity of the offence.
