Extended limitation in central excise requires proof of wilful suppression, not clerical accounting errors or negligence.

The proviso to Section 11A of the Central Excise Act, 1944 applies only where the department proves positive suppression, wilful misstatement, fraud or collusion; mere non-payment, negligent accounting or clerical register errors are insufficient. As the notice did not specifically allege deliberate suppression in relation to the shortages and the record showed incorrect postings and clerical mistakes, the extended limitation period could not be invoked. The duty demand on shortages was therefore time-barred, and the related penalty and confiscation under Rule 173Q(2) of the Central Excise Rules, 1944 also failed.

Issues: Whether the extended period of limitation could be invoked for the duty demand raised on shortages, and whether the consequential demand, penalty and confiscation could be sustained.

Analysis: The demand was raised beyond the normal period and could be saved only by the proviso to Section 11A of the Central Excise Act, 1944. For that proviso to apply, there must be a positive act of wilful suppression, misstatement, fraud, collusion or similar conduct, and not mere non-payment of duty or negligent accounting. The notice did not specifically allege deliberate suppression in relation to the shortages, and the record indicated that the shortages arose from incorrect posting and clerical errors in the statutory register. In the circumstances, the same type of erroneous entries that explained the larger discrepancies could not, without more, justify invocation of the extended period. Once limitation failed, the associated penalty and confiscation under Rule 173Q(2) of the Central Excise Rules, 1944 also could not stand.

Conclusion: The extended period of limitation was not applicable, the duty demand on shortages was time-barred, and the penalty and confiscation were unsustainable. The appeal was therefore allowed in favour of the assessee.

Ratio Decidendi: The proviso to Section 11A of the Central Excise Act, 1944 can be invoked only on proof of positive suppression, wilful misstatement, fraud or collusion, and not on mere negligence or clerical accounting errors; where that foundation is absent, the time-barred demand and consequential penal action cannot be sustained.
