Excise duty and penalty on aluminium circles fail where the case rests on presumptions instead of corroborative evidence.

Excise duty on aluminium circles was found unsustainable where the department relied mainly on post-period sample thickness and assumptions about earlier removals, without cogent corroborative evidence linking the alleged liability to the relevant period. The Board noted that evidence supported the assessee's case that thickness may change after deep drawing, and that presumptions could not replace proof. Penalty under Rule 173-Q was also rejected because it is a drastic penal provision and, absent reliable proof of contravention, the penalty was excessive and unwarranted.

Issues: (i) Whether the demand of central excise duty on aluminium circles was sustainable on the basis of the material relied upon by the department. (ii) Whether the penalty imposed under Rule 173-Q of the Central Excise Rules, 1944 was justified.

Issue (i): Whether the demand of central excise duty on aluminium circles was sustainable on the basis of the material relied upon by the department.

Analysis: The demand was founded mainly on the thickness of samples drawn after the relevant period and on assumptions about the thickness of circles earlier removed from the factory. The Board found that the request to the Test House to consider the effect of the deep drawing process had not been communicated, that experimental and certificate evidence supported the appellants' contention that thickness varies after such process, and that the Collector's conclusion rested on presumptions without cogent corroboration. In the absence of satisfactory corroborative evidence linking the alleged duty liability to the earlier period, the demand could not be sustained.

Conclusion: The demand of duty was not sustainable and was set aside in favour of the assessee.

Issue (ii): Whether the penalty imposed under Rule 173-Q of the Central Excise Rules, 1944 was justified.

Analysis: The Board treated Rule 173-Q as conferring drastic penal power requiring circumspection and caution. Since the duty demand itself was unsupported by reliable material and the alleged contravention was not established by firm evidence, the penalty was held to be excessive and unwarranted.

Conclusion: The penalty was not justified and was set aside in favour of the assessee.

Final Conclusion: The appeal was allowed in full, with both the duty demand and the penalty annulled.

Ratio Decidendi: A demand of excise duty or a penalty under a drastic penal provision cannot be sustained on presumptions and conjectures alone and must rest on cogent corroborative evidence establishing the contravention.
