Extended limitation in central excise requires deliberate suppression with intent to evade duty; disclosed facts defeat extended time

Extended limitation under the proviso to Section 11A(1) of the Central Excise Act applies only where the Department proves deliberate suppression of material facts with intent to evade duty. Here, the assessee's classification lists were checked and approved, grade-wise records were maintained, a detailed Modvat declaration disclosed the raw materials used, and correspondence showed the use of more than 100 chemicals in manufacture. On those facts, wilful suppression was not established, mere non-disclosure was insufficient, and the demand fell outside the normal period. The extended limitation period was therefore not available and the duty demand was time-barred.

Issues: Whether the extended period of limitation under the proviso to Section 11A(1) of the Central Excise Act, 1944 could be invoked on the allegation that the assessee suppressed the use of additional materials in the manufacture of ABS polymers.

Analysis: The classification lists had been checked, verified and approved, the assessee had maintained grade-wise records, and a detailed Modvat declaration under Rule 57G of the Central Excise Rules, 1944 disclosed the raw materials used in manufacture. The record also showed correspondence indicating that more than 100 chemicals were used in producing ABS polymers. In these circumstances, the non-disclosure alleged by the Department was not shown to be deliberate, and the element of wilful suppression with intent to evade duty was absent. The demand was therefore beyond the normal period and could not be sustained by resort to the extended limitation period.

Conclusion: The extended period of limitation was not invocable and the duty demand was time-barred, in favour of the assessee.

Ratio Decidendi: For invoking the extended period under the proviso to Section 11A(1), the Department must establish deliberate suppression of material facts with intent to evade duty; where the relevant facts were disclosed or were otherwise known, mere omission is insufficient.
