Disclosure in returns and duty documents defeats suppression and blocks extended limitation in central excise disputes

Where RT-12 returns and duty-paying documents disclosed the fabrication of pipes on job-work basis from free-issue material, the relevant facts were treated as available to the department and suppression was not inferred. The filing record, including challans, invoices, work orders and related documents, showed the nature of the work, the site of fabrication and the project use of the pipes. On that basis, mere non-filing of a declaration was held insufficient by itself to establish suppression or intent to evade duty, so the extended limitation period was not available and the demand was time-barred.

Issues: Whether the extended period of limitation under the proviso to section 11A(1) of the Central Excise Act, 1944 could be invoked on the ground of suppression when the assessee had filed RT-12 returns and accompanying duty-paying documents, and whether non-filing of the declaration under Rule 173C of the Central Excise Rules, 1944 by itself established suppression.

Analysis: The record showed that the goods were cleared under challans and invoices describing the fabrication of pipes on job work basis from free issue material supplied by the customer. The RT-12 returns were filed along with the duty-paying documents, which were available for scrutiny by the department. The work order and related documents disclosed the nature of the work, the site at which fabrication took place, and the use of the pipes in the project. On these facts, the Tribunal found that the relevant material facts were within the knowledge of the Revenue and that there was no basis to infer suppression or any intention to evade duty.

Conclusion: The extended period was not available, the demand was time-barred, and the assessee succeeded on the issue.

Ratio Decidendi: Where the relevant facts are disclosed through returns and duty-paying documents, mere non-filing of a declaration does not by itself establish suppression or justify invocation of the extended limitation period.
