Extended limitation and chassis classification fail where suppression is unproved and principal design is not established.

Additional Collector-issued show cause notice was treated as valid because the definition of "Collector" in the Central Excise Rules was wide enough to include an Additional Collector. Classification of bare chassis under sub-heading 8706.30 required the Department to prove, with affirmative material, that they were principally designed for motor vehicles of Heading 87.03; mere capability of such use was insufficient, so the classification was not sustainable. Extended limitation under Section 11A was unavailable because the record did not show wilful suppression or conscious withholding of information, and the approved classification list had already disclosed the relevant particulars and uses. The demand and penalty could not be sustained.

Issues: (i) Whether the Additional Collector was competent to issue the show cause notice invoking the extended period under the proviso to Section 11A; (ii) whether "Bare Chassis" of 2400 mm wheel base were classifiable under sub-heading 8706.30 as meant for motor vehicles of Heading 87.03; and (iii) whether the extended period beyond six months could be invoked for confirmation of the demand.

Issue (i): Whether the Additional Collector was competent to issue the show cause notice invoking the extended period under the proviso to Section 11A.

Analysis: The definition of "Collector" in the Central Excise Rules was treated as wide enough to include an Additional Collector. The notice was therefore not invalid merely because it was issued by the Additional Collector. The cited authority against competence was distinguished on facts, as it dealt with a notice issued by a Superintendent.

Conclusion: The show cause notice issued by the Additional Collector was competent and valid.

Issue (ii): Whether "Bare Chassis" of 2400 mm wheel base were classifiable under sub-heading 8706.30 as meant for motor vehicles of Heading 87.03.

Analysis: The Department had the burden to establish, by relevant material, that the chassis were principally designed for vehicles of Heading 87.03. The classification list disclosed the wheel base and the use of the chassis for vehicles under more than one heading. Mere capability of use for Heading 87.03 vehicles, without proof of special design or supporting enquiry, was insufficient to sustain classification under sub-heading 8706.30.

Conclusion: The classification under sub-heading 8706.30 was not sustainable.

Issue (iii): Whether the extended period beyond six months could be invoked for confirmation of the demand.

Analysis: The record did not show wilful suppression or conscious withholding of information. The approved classification list had disclosed the relevant chassis particulars and uses, and the Department had not discharged the burden required to justify invocation of the extended limitation period. The conditions necessary for extended limitation were therefore not satisfied.

Conclusion: Invocation of the extended period was not justified.

Final Conclusion: The demand and penalty could not be sustained, and the appeal succeeded on the substantive and limitation issues.

Ratio Decidendi: For extended limitation under Section 11A, the Department must prove wilful suppression or comparable intent to evade duty, and a tariff classification based on principal design must be supported by affirmative evidence, with the burden resting on the Department.
