Undervaluation supported by corroborative invoices upheld, but separate partner penalties deleted once the firm was penalized.

A retracted admission of undervaluation may still be relied on when it is corroborated by independent documentary evidence, including supplier invoices obtained through customs and the importer's conduct; on that basis, the differential duty demand was sustained. Penalty and interest were also upheld for the relevant consignment, as the Tribunal found the customs provisions applicable in the manner adopted by the adjudicating authority. However, separate penalties on the partners were unsustainable once the firm had already been penalized on the same facts, so those penalties were deleted.

Issues: (i) Whether the imported tyres were undervalued and whether the differential duty demand was sustainable. (ii) Whether penalty and interest under the relevant customs provisions were applicable to the consignments cleared before the stated effective date. (iii) Whether separate penalties could be imposed on the partners of the importing firm.

Issue (i): Whether the imported tyres were undervalued and whether the differential duty demand was sustainable.

Analysis: The valuation dispute was decided on the basis of the manufacturer's invoices obtained through German Customs, which showed a materially higher price and matched the quantities covered by the imports. The importer had produced traders' invoices instead of the manufacturer's invoices, and one partner admitted undervaluation and paid part of the differential duty. The retraction of that admission did not displace its evidentiary value because it was corroborated by documentary material and the conduct of the importer, including acceptance of enhancement without protest.

Conclusion: The duty demand founded on undervaluation was sustained and was against the assessee.

Issue (ii): Whether penalty and interest under the relevant customs provisions were applicable to the consignments cleared before the stated effective date.

Analysis: The Tribunal held that the differential duty and consequential interest and penalty were correctly applied at least in respect of the relevant bill of entry, because the goods were cleared only after payment and final adjustment of duty. The objection based on the filing dates of the bills of entry was not accepted as a bar to the invocation of the provisions in the manner adopted by the adjudicating authority.

Conclusion: The levy of penalty and interest against the firm was sustained and was against the assessee.

Issue (iii): Whether separate penalties could be imposed on the partners of the importing firm.

Analysis: The Tribunal followed the binding High Court view that once the firm is penalized, separate penalties on the partners are not sustainable on the same facts.

Conclusion: The penalties imposed on the partners were set aside and were in favour of the assessee.

Final Conclusion: The appeal succeeded only to the limited extent of deleting the penalties on the partners, while the duty demand and the penalty on the importing firm were affirmed.

Ratio Decidendi: A retracted admission of undervaluation can be relied upon when it is corroborated by independent documentary evidence, and separate penalties on partners are not sustainable where the firm itself has been penalized for the same misconduct.
