Mandatory valuation disclosure under excise rules: deliberate non-disclosure can amount to suppression and trigger extended limitation.

Mandatory disclosure of valuation particulars under Rule 173C of the Central Excise Rules, 1944 was treated as an essential statutory safeguard, not a mere procedural formality. Non-filing of the declaration and failure to inform the department that goods were being undervalued amounted to non-disclosure of material facts. On that basis, such conduct constituted suppression with intent to evade duty, making invocation of the extended period of limitation justified and attracting penalty provisions. The conclusion recorded was that the assessee's favour was unsustainable.

Issues: Whether non-filing of the declaration and non-disclosure of valuation particulars required under Rule 173C of the Central Excise Rules, 1944 amounted to suppression of facts with intent to evade duty, so as to justify invocation of the extended period of limitation and the consequential penalty.

Analysis: Rule 173C imposed mandatory obligations on the assessee to disclose valuation-related particulars to the department in the prescribed manner. The order found that no declaration was filed and the department was not informed that the goods were being undervalued. Such disclosure was not a mere procedural formality but an essential statutory safeguard for proper assessment and prevention of duty evasion. Failure to comply with this requirement resulted in non-disclosure of material facts. The authorities and precedents relied on by the respondents did not assist them because the relevant facts were not already known to both sides, nor was there any scope for doubt about the disclosure requirement during the relevant period.

Conclusion: The extended period of limitation was rightly invocable and the penalty provisions were attracted; the finding in favour of the assessee was unsustainable.

Ratio Decidendi: Where the statute requires mandatory disclosure of valuation particulars to the department, deliberate non-disclosure of such material facts constitutes suppression with intent to evade duty and justifies invocation of the extended limitation period.
