Retrospective valuation amendment and suppression of facts justified extended limitation and sustained differential duty demand.

Retrospective amendment to the valuation provision did not require pending show-cause notices to be reissued, because the legal basis for the duty demand continued after the amendment. The demand was not barred by limitation where excess duty was recovered through invoices and bills but not disclosed in returns and gate passes, as that constituted suppression of facts and justified use of the extended period. Reliance on a press note did not vitiate the adjudication, since the order was founded on the retrospective statutory amendment and an independent assessment of the facts. Differential duty was therefore upheld, and the cross-objections failed.

Issues: (i) whether the show-cause notices were required to be reissued after the retrospective amendment to the valuation provision; (ii) whether the assessment demand was barred by limitation; and (iii) whether the adjudication was vitiated for alleged non-application of mind because of reliance on a press note.

Issue (i): whether the show-cause notices were required to be reissued after the retrospective amendment to the valuation provision

Analysis: The retrospective amendment to the valuation provision did not require the department to restart the proceedings by issuing fresh notices. The earlier Supreme Court decision relied upon by the appellants was read as dealing with the effect of retrospective amendments on duty recovery, not as laying down any rule that pending notices automatically lapse or must be reissued. The legal basis for the demand continued to exist after the amendment.

Conclusion: The contention was rejected and the notices were held to remain valid.

Issue (ii): whether the assessment demand was barred by limitation

Analysis: Although some notices would have been time-barred on the ordinary period of limitation, the excess duty was recovered through invoices and bills and was not reflected in the returns and gate passes finalised by the department. That amounted to suppression of facts and brought the case within the extended period under the proviso to the limitation provision.

Conclusion: The demand was held not to be barred by limitation.

Issue (iii): whether the adjudication was vitiated for alleged non-application of mind because of reliance on a press note

Analysis: The order was not based on a press note. It was founded on the retrospective statutory amendment governing valuation, and the factual premise for the demand was independently considered by the adjudicating authority. The plea of non-application of mind was therefore unfounded.

Conclusion: The adjudication was held to be legally valid.

Final Conclusion: The demand for differential duty was upheld, the appeal failed on merits, and the connected cross-objections could not be maintained.

Ratio Decidendi: Excess duty recovered through invoices, if not disclosed in the statutory returns and gate passes, constitutes suppression of facts and attracts the extended limitation period for recovery under excise law.
