Suppression of facts and dummy clearances justified extended limitation, with no natural justice breach or appellate interference on merits.

Concurrent findings of suppression of material facts, non-production of records, and unsupported trading transactions justified invocation of the extended limitation period under the proviso to Section 11-A(1) of the Central Excise Act, 1944. The alleged fire destroying records and the claimed transactions were not established, and clearances through a dummy concern supported the fraud/suppression inference. No breach of natural justice was made out because the assessee had repeated opportunities to produce records and no prejudice from non-supply of documents was shown. The Tribunal's affirmance of the demand and penalty on merits was sustained, as no error of law or perversity was demonstrated.

Issues: (i) Whether the extended period of limitation under the proviso to Section 11-A(1) of the Central Excise Act, 1944 was validly invoked on the basis of suppression of facts and fraud. (ii) Whether there was any breach of principles of natural justice for non-supply of relied upon or non-relied upon documents. (iii) Whether the Tribunal committed any error in affirming the demand and penalty on merits.

Issue (i): Whether the extended period of limitation under the proviso to Section 11-A(1) of the Central Excise Act, 1944 was validly invoked on the basis of suppression of facts and fraud.

Analysis: The record showed repeated demands for invoices and documents, non-production of books and records, a belated plea that the records were destroyed in a fire, and findings that the alleged fire and the claimed trading transactions were not established. The authorities below also found that clearances were shown through a dummy concern and that the material facts were suppressed. These concurrent findings supported invocation of the extended period.

Conclusion: The extended period of limitation was validly invoked and the finding is against the assessee.

Issue (ii): Whether there was any breach of principles of natural justice for non-supply of relied upon or non-relied upon documents.

Analysis: The assessee was given repeated opportunities to produce records and was heard at the adjudication and appellate stages. The Court found that the relevant evidence and materials were duly considered and that no prejudice from non-supply of documents was established.

Conclusion: No breach of principles of natural justice was made out and the finding is against the assessee.

Issue (iii): Whether the Tribunal committed any error in affirming the demand and penalty on merits.

Analysis: The Tribunal's findings on unproved trading purchases, dummy unit clearances, and suppression were based on evidence and were concurrent findings of fact. The Court held that no error of law or perversity was shown to justify interference in appeal.

Conclusion: The Tribunal's order on merits was upheld and the finding is against the assessee.

Final Conclusion: The appeal was held to be without merit, and the demand and connected findings were sustained, resulting in dismissal of the challenge to the revenue's case.

Ratio Decidendi: Concurrent findings of suppression of material facts and unsupported transactions justify invocation of the extended period of limitation under the proviso to Section 11-A(1) of the Central Excise Act, 1944, and such factual findings are not to be interfered with in appeal absent legal error or perversity.
