Extended limitation under Central Excise law may apply where a declaration is false and key exemption facts are not disclosed.

Extended limitation under Section 11A of the Central Excise Act, 1944 was discussed in the context of a declaration under Rule 173B that distinguished branded from own-branded or unbranded pipes and tubes. The court treated the declaration as false because the available records did not identify which customers received branded goods and which received other categories, leaving the relevant exemption facts undisclosed to the Revenue. It was noted that RG-1 entries, RT-12 returns, the Superintendent's letter and the assessee's reply did not supply the basic particulars needed to verify the claim. The absence of further investigation did not bar invocation of the extended period where the foundational disclosure itself was incomplete or false.

Issues: Whether the extended period of limitation under Section 11A of the Central Excise Act, 1944 could be invoked on the ground that the declaration filed by the assessee was false and the relevant facts were not fully disclosed to the Revenue.

Analysis: The declaration filed under Rule 173B of the Central Excise Rules distinguished between branded and own-branded or unbranded pipes and tubes. The Tribunal treated the declaration as false because the RG-1 register, the RT-12 returns, the Superintendent's letter, and the assessee's reply did not furnish basic material to identify which customer received branded goods and which received own-branded or unbranded goods. On that footing, the facts necessary to test the exemption claim were not fully within the Revenue's knowledge. The absence of further investigation did not prevent invocation of the extended period where the foundational disclosure itself was false.

Conclusion: The extended period under Section 11A was validly invoked, and the assessee's challenge failed.

Ratio Decidendi: Where the declaration itself is found to be false and the relevant particulars are not adequately disclosed, the Revenue may invoke the extended period of limitation notwithstanding filing of returns and prior correspondence.
