Extended limitation under Central Excise law fails without suppression; pre-notice duty payment does not erase interest liability.

In the absence of evidence of suppression of facts, wilful misstatement, or intent to evade duty, the extended limitation period under the Central Excise Act could not be invoked and the demand was time-barred. Payment of differential duty before a show cause notice did not, by itself, remove liability to interest, but no separate relief on interest or penalty survived once the notice itself failed on limitation and lack of foundational grounds. The revenue appeal was rejected, leaving the assessee's position undisturbed.

Issues: (i) Whether the demand notice could validly invoke the extended period of limitation in the absence of evidence of misdeclaration or suppression of facts with intent to evade duty; (ii) Whether payment of differential duty before issuance of show cause notice displaced liability to interest and penalty.

Issue (i): Whether the demand notice could validly invoke the extended period of limitation in the absence of evidence of misdeclaration or suppression of facts with intent to evade duty.

Analysis: The notice did not bring out evidence establishing suppression, wilful misstatement, or intent to evade duty. The record also showed that the differential duty had been paid before the notice, and the adjudicating authority itself accepted that there was no suppression of facts. In such circumstances, the proviso to section 11A(1) of the Central Excise Act, 1944 could not be invoked to sustain a demand beyond the normal period.

Conclusion: The extended period of limitation was not available, and the demand notice was time-barred.

Issue (ii): Whether payment of differential duty before issuance of show cause notice displaced liability to interest and penalty.

Analysis: The discussion distinguished interest under section 11AB of the Central Excise Act, 1944 from penalty under section 11AC of the Central Excise Act, 1944, and noted that payment of duty before notice did not by itself absolve liability to interest. The reasoning, however, remained tied to the larger conclusion that the notice itself was unsustainable for want of limitation and absence of suppression.

Conclusion: No separate relief on interest or penalty survived, and the revenue appeal failed.

Final Conclusion: The appeal was rejected on limitation and lack of foundational grounds for invoking the extended period, leaving the assessee's position undisturbed.

Ratio Decidendi: In the absence of evidence of suppression of facts or wilful misstatement with intent to evade duty, the extended limitation period under section 11A(1) of the Central Excise Act, 1944 cannot be invoked; payment of duty before notice does not, by itself, negate statutory liability to interest.
