Suppression of material facts can trigger extended limitation, while retrospective penalty provisions cannot apply to prior periods.

Misdescription of an activity and suppression of the true factual position material to duty liability can justify invocation of the extended limitation period, even where a classification list was approved and returns were filed, because such procedural compliance does not cure non-disclosure. The assessee's representation that the activity amounted to manufacture was found inconsistent with the actual testing of only part of the goods, so the longer limitation period was upheld. Penalty and interest could not be sustained under the later rules for the relevant prior period because those provisions were not retrospective; however, penalty remained maintainable under the general penal provision, albeit in reduced form, and the interest demand was set aside.

Issues: (i) Whether the extended period of limitation could be invoked on the facts of the case. (ii) Whether the personal penalty and interest were sustainable, and if so to what extent.

Issue (i): Whether the extended period of limitation could be invoked on the facts of the case.

Analysis: The assessee had availed credit on liquid oxygen and filed a classification list describing the process as manufacture of medicinal oxygen, while the actual activity was only testing of a small portion of the tanker contents and clearance of the goods as such. The approval of the classification list and filing of returns did not displace the finding that the true factual position was not disclosed. The assessee knew that the testing activity did not amount to manufacture, yet represented otherwise to the department. On these facts, the non-disclosure was treated as sufficient to attract the longer limitation period.

Conclusion: The extended period of limitation was rightly invoked, against the assessee.

Issue (ii): Whether the personal penalty and interest were sustainable, and if so to what extent.

Analysis: Penalty and interest were not sustainable under Rule 57-I(4) and Rule 57-I(5) for the relevant prior period because those provisions could not be applied retrospectively. At the same time, the conduct still justified penalty under Rule 173Q. Considering the overall facts, the quantum of penalty was reduced substantially, and the interest demand was set aside.

Conclusion: The penalty was sustained only in reduced form under Rule 173Q, and the interest demand was set aside, partly in favour of the assessee.

Final Conclusion: The duty demand was upheld on limitation, while the penalty was curtailed and the interest liability was deleted.

Ratio Decidendi: Where an assessee misdescribes its activity and fails to disclose the true factual position material to duty liability, approval of a classification list or filing of returns does not by itself bar invocation of the extended period of limitation; a penalty not sustainable under a specific rule for want of retrospective operation may still be imposed under a general penal provision if the facts justify it.
