Prospective duty reclassification where prior price list acceptance cannot justify retrospective recovery absent a change in law

Prior departmental acceptance of a price list, when acted on with full knowledge of clearances, does not prevent a later correction in classification or valuation, but the revised duty liability cannot be fastened retrospectively in the absence of a change in law or a binding judicial ruling. Where duty was short-levied because of an erroneous earlier view, the Department may issue a show-cause notice and recover the differential duty only prospectively from the notice date. The revised demand was therefore effective from the date of the show-cause notice, not from the original price list.

Issues: Whether a classification and price list earlier accepted by the Department, though found to be erroneous, could justify recovery of differential duty retrospectively from the date of the original price list or only prospectively from the date of the show-cause notice.

Analysis: The accepted price list was acted upon by the Department and the goods were cleared with departmental knowledge. In the absence of any amendment in law or intervening judicial pronouncement, the earlier acceptance could not be reopened so as to fasten liability retrospectively. Although the Department had power to issue a notice where duty had been short-levied due to erroneous application of law, the reassessment of liability could operate only from the date on which the Department chose to issue the notice.

Conclusion: The reclassification and revised duty demand were held effective only from the date of the show-cause notice, and not from the date of the original price list; the appeal was accordingly partly in favour of the assessee.

Final Conclusion: Prior departmental acceptance of a price list does not bar a lawful notice for short levy, but any corrected duty liability based on the later view of classification operates prospectively from the notice date in the absence of a change in law or binding judicial ruling.

Ratio Decidendi: Where the Department has accepted and acted upon a price list with full knowledge of the clearances, a later correction in classification or valuation, absent a change in law or judicial pronouncement, can be given effect only prospectively from the date of the show-cause notice.
