Transaction-wise proof governs undervaluation claims, while successor liability is limited to confirmed excise arrears already crystallized.

In central excise undervaluation cases, generalized extrapolation based on third-party records and statements is insufficient; assessable value must be determined transaction-wise on legally sustainable evidence, so the demand required remand for re-quantification. Recovery from a successor is confined to confirmed arrears existing at the time of transfer, and a fresh demand for unconfirmed predecessor liability cannot be fastened on the successor or on legal heirs where the claim had not crystallized before death. Allegations of clandestine removal require cogent proof of manufacture, clearance, and receipt of consideration; on the available record, that charge also warranted reconsideration rather than final confirmation.

Issues: (i) Whether the demand of central excise duty on alleged undervaluation could be sustained on the basis of third-party records and statements, and whether the duty had to be re-quantified transaction-wise; (ii) whether duty allegedly pertaining to the predecessor business could be recovered from the successor entity and whether the demand against the deceased proprietors' concerns could survive; (iii) whether the alleged clandestine removal in the case of Prime Veneers was established on the available evidence.

Issue (i): Whether the demand of central excise duty on alleged undervaluation could be sustained on the basis of third-party records and statements, and whether the duty had to be re-quantified transaction-wise?

Analysis: The records recovered from the dealer and the statements recorded during investigation furnished some evidence of cash collection over and above invoice value, but the quantification adopted in the show cause notice proceeded on a generalized percentage and approximation. The evidence on record did not justify a uniform extrapolation across all clearances. The correct approach in a case of undervaluation after introduction of transaction value is to examine each transaction on the basis of the available evidence and determine the assessable value in a legally sustainable manner. On that footing, the confirmation based on a theoretical formula could not stand, though the material was sufficient to indicate that undervaluation had occurred.

Conclusion: The duty confirmation required remand for transaction-wise re-quantification, and the demand could not be sustained on a generalized formula.

Issue (ii): Whether duty allegedly pertaining to the predecessor business could be recovered from the successor entity and whether the demand against the deceased proprietors' concerns could survive?

Analysis: Section 11 permits recovery of existing confirmed arrears from a successor in specified circumstances, but it does not authorize issuance of a fresh demand against the successor for unconfirmed liability of the predecessor. Since no confirmed arrears existed at the time of takeover, the successor company could not be fastened with the predecessor's alleged dues in the manner attempted. Likewise, where the proprietor had died and the demand had not crystallized into a confirmed recovery against the deceased during lifetime, the demand could not be pursued against the legal heirs or the successor concern on the facts found.

Conclusion: The demands against the successor and the demands dropped for the periods prior to death of the proprietors were not liable to be interfered with.

Issue (iii): Whether the alleged clandestine removal in the case of Prime Veneers was established on the available evidence?

Analysis: Clandestine removal is a serious allegation and requires cogent evidence of manufacture, clearance and receipt of consideration. The material relied upon was insufficient to conclusively establish the charge, and the matter required a fresh examination of the evidence and the money trail. The available record did not justify a final finding against the assessee on this allegation without further verification.

Conclusion: The clandestine removal demand was remanded for reconsideration.

Final Conclusion: The departmental appeals failed, the individual penalties on the concerned persons were sustained, and the principal duty demands against the assessees were left to be reworked or re-examined in remand where required.

Ratio Decidendi: In undervaluation cases under the central excise law, generalized extrapolation cannot substitute for transaction-wise proof, and recovery from a successor is confined to confirmed arrears existing at the time of transfer.
