Bona fide classification dispute defeats extended limitation where non-filing of excise papers is not wilful suppression.

Extended limitation could not be invoked where continuous computer stationery had a debatable classification and the assessee could reasonably believe the goods fell under Heading 4820 and were exempt from duty. On that bona fide belief, non-filing of a classification list and non-compliance with excise formalities did not amount to wilful suppression of facts. The extended period was therefore unavailable, and the duty demand and penalty could not be sustained on that basis.

Issues: Whether the extended period of limitation could be invoked against the assessee for non-filing of classification list and non-compliance with excise formalities in relation to continuous computer stationery.

Analysis: The classification of continuous computer stationery was doubtful until the Board's circular clarified the position. In that background, it was possible for the assessee to believe that the goods were classifiable under Heading 4820 and therefore exempt from duty. If such a bona fide belief existed, filing of a classification list or compliance with excise formalities was not required. The allegation of wilful suppression of facts for invoking the extended period was therefore not sustainable.

Conclusion: The extended period of limitation was not available to the department, and the assessee succeeded on this issue.

Final Conclusion: The demand and penalty could not be sustained on the basis of extended limitation, and the assessee's appeal was allowed.

Ratio Decidendi: Where a duty liability depends on a debatable classification and the assessee acts under a bona fide belief of exemption, non-filing of classification papers does not amount to wilful suppression so as to attract the extended period of limitation.
