Clandestine excise demands need tangible evidence; exemptions require disclosed factual basis, while waste-paper computation errors can defeat denial.

Central excise demands for alleged clandestine manufacture and clearance cannot rest on estimated production ratios or reconstructed calculations alone; clear, tangible corroborative evidence is required, so the demand on that basis was set aside. Exemption disputes also must be supported by a properly disclosed and reasoned factual foundation: the claim relating to paper cleared for text book printing failed because the notice did not clearly establish the alleged diversion. For Notification No. 47/83-C.E., waste paper consumption had to be correctly computed, leading to remand for 1983-84 and deletion of the demands for 1984-85 and 1985-86. Confiscation of paper and plant-related assets was not sustained, but the director's penalty was maintained.

Issues: (i) whether the demand based on alleged clandestine production and clearance could be sustained on the basis of estimated production ratios and reconstructed calculations; (ii) whether exemption under Notification No. 163/67-C.E. was wrongly availed in respect of paper said to have been cleared for text book printing; (iii) whether the benefit of Notification No. 47/83-C.E. was available for paper manufactured with more than 50% waste paper for the relevant years; and (iv) whether the confiscation of paper, land, building, plant and machinery and the penalty on the director were sustainable.

Issue (i): whether the demand based on alleged clandestine production and clearance could be sustained on the basis of estimated production ratios and reconstructed calculations.

Analysis: The demand was worked out from assumed raw material consumption, assumed pulp yield and an assumed pulp-to-paper conversion ratio. The relied upon documents and the basis of the abstract calculation were not fully available, and the demand was not supported by tangible corroborative evidence of actual clandestine manufacture and removal. The revenue's burden to establish taxability and suppression was not discharged merely by theoretical estimation or by comparing figures from another unit.

Conclusion: The demand on alleged clandestine clearance was not sustainable and was set aside.

Issue (ii): whether exemption under Notification No. 163/67-C.E. was wrongly availed in respect of paper said to have been cleared for text book printing.

Analysis: The show cause notice did not set out the particulars of the alleged diversion with sufficient clarity, and the adjudication relied on details and documents that were not properly disclosed in the notice. The quantity alleged to have been diverted was not established from the materials made available, and the finding travelled beyond the foundation of the notice.

Conclusion: The demand based on alleged wrongful availment of Notification No. 163/67-C.E. was not sustainable and was set aside.

Issue (iii): whether the benefit of Notification No. 47/83-C.E. was available for paper manufactured with more than 50% waste paper for the relevant years.

Analysis: For 1983-84, the assessee accepted that waste paper consumption was below the threshold, but the duty computation contained arithmetical errors requiring recomputation. For 1984-85, the department's own figures showed an error in working out the percentage of waste paper consumed, and the denial of exemption could not stand. For 1985-86, no reasoned finding supported the conclusion that consumption was below 50%, and the assessee's working was not effectively rebutted.

Conclusion: The demand for 1983-84 was remanded for correct computation, and the demands for 1984-85 and 1985-86 were set aside.

Issue (iv): whether the confiscation of paper, land, building, plant and machinery and the penalty on the director were sustainable.

Analysis: The confiscation of the seized paper was not justified on the available material, and once that basis failed, the consequential confiscation of land, building, plant and machinery and the redemption fines also could not survive. The penalty on the director was however supported by his role in the affairs of the unit and by the surviving finding of wrongful availment of exemption for 1983-84.

Conclusion: The confiscations and redemption fines were set aside, while the penalty on the director was upheld.

Final Conclusion: The assessee succeeded on the principal demands and on the confiscation issues, but the matter relating to 1983-84 exemption was remanded for fresh computation and the director's penalty was maintained, resulting in only limited relief for the revenue on the surviving issue.

Ratio Decidendi: A demand of central excise duty for clandestine manufacture and removal cannot be sustained on estimates or assumptions alone and must rest on clear, tangible corroborative evidence; where an exemption claim is denied, the department must also support its computation by a reasoned and disclosed basis.
