Bona fide classification dispute and full disclosure defeat extended limitation; ignored technical evidence requires fresh adjudication.

Technical reports and government laboratory test certificates were material to the product classification and exemption dispute, and their complete non-consideration by the original authority required fresh examination on merits. The note also states that the extended period of limitation under the proviso to section 11A(1) was not available because the assessee had made early disclosure of the product, process and exemption basis, supplied further particulars when asked, and pursued a bona fide classification claim. In the absence of suppression with intent to evade duty, the demand could operate only for the normal period.

Issues: (i) Whether the classification of the product and the exemption claim required reconsideration because the original authority failed to consider the technical reports and certificates produced by the assessee. (ii) Whether the extended period of limitation under the proviso to section 11A(1) was invocable on the facts of the case.

Issue (i): Whether the classification of the product and the exemption claim required reconsideration because the original authority failed to consider the technical reports and certificates produced by the assessee.

Analysis: The technical opinions and test reports from reputed government laboratories were material to the classification dispute. The original order did not discuss them at all. In a matter turning on the nature and character of the product, such total non-consideration amounted to denial of a fair hearing and non-application of mind. The matter therefore required fresh examination on merits.

Conclusion: The classification issue was remanded for de novo consideration in favour of the assessee.

Issue (ii): Whether the extended period of limitation under the proviso to section 11A(1) was invocable on the facts of the case.

Analysis: The assessee had approached the department at an early stage, disclosed the product, the manufacturing process, and the basis of the exemption claim, and supplied further particulars whenever asked. The product was a new one with no prior domestic precedent, and the assessee's stand was based on a bona fide claim of classification and exemption. Mere assertion of a different classification by the department, without a clear alternative classification being communicated and without technical testing during the relevant period, was insufficient to establish suppression with intent to evade duty. The reliance on later HSN reasoning could not sustain invocation of the extended period.

Conclusion: The extended period of limitation was not invocable and the demand was confined to the normal period.

Final Conclusion: The demand could not survive for the extended period, and the classification and related consequential issues were sent back for fresh decision on merits.

Ratio Decidendi: Suppression with intent to evade duty is not established where the assessee has made early and substantive disclosure to the department and the classification dispute is bona fide; material technical evidence ignored by the original authority warrants remand for fresh adjudication.
