Extended limitation under excise law fails without proved suppression; limited duty demand remanded and penalty set aside.

Approved classification, extended licence records, and the absence of proved collusion or deliberate misdeclaration meant the extended limitation period under the proviso to Section 11A(1) could not be invoked, and some notices were also without jurisdiction. The resulting duty demand was therefore barred to that extent. For the limited surviving portion, the basis for denying exemption was not adequately found, so capital investment and exemption eligibility required fresh adjudication. As the principal demand failed on limitation and the remainder was remitted for de novo determination, the penalty could not be sustained.

Issues: (i) whether the extended period under the proviso to Section 11A(1) could be invoked and the show cause notices were within limitation and jurisdiction; (ii) whether the demand for duty and the penalty could be sustained, and whether the surviving demand required fresh determination of capital investment and exemption eligibility.

Issue (i): Whether the extended period under the proviso to Section 11A(1) could be invoked and the show cause notices were within limitation and jurisdiction.

Analysis: The classification list had been filed and approved by the proper officer, the licence had been obtained and extended, and the record did not establish any collusion or deliberate misdeclaration attributable to the assessee. In these circumstances, invocation of the extended limitation period was not justified. Further, certain notices were held to be without jurisdiction as they had been issued by an not competent to issue them under the proviso to Section 11A(1).

Conclusion: The notices were held to be barred by limitation, and some notices were also held to be without jurisdiction, in favour of the assessee.

Issue (ii): Whether the demand for duty and the penalty could be sustained, and whether the surviving demand required fresh determination of capital investment and exemption eligibility.

Analysis: The order did not contain adequate findings on the precise basis for denying exemption under the relevant tariff and notification regime. For the notice that was partly within time, the quantum of capital investment and the resulting eligibility for exemption required fresh adjudication. Since the major portion of the demand failed on limitation and the remaining demand was left for de novo determination, the penalty could not be sustained.

Conclusion: The demand was set aside except to the limited extent requiring fresh adjudication, and the penalty was set aside, in favour of the assessee.

Final Conclusion: The assessee succeeded on limitation, jurisdiction, and penalty, while only a limited part of the duty dispute was remitted for fresh determination.

Ratio Decidendi: Approved classification and absence of established collusion or deliberate suppression negate invocation of the extended limitation period, and penalty cannot survive where the principal demand fails or is left for fresh adjudication.
