Natural justice in excise demand proceedings requires disclosure of adverse material and a real opportunity to respond.

Excise demand under Rule 9(2) required disclosure of the material relied on and a real opportunity for the assessee to meet adverse inferences. The Court treated the demand-making inquiry as quasi-judicial in character, and held that even if administrative, fair play and natural justice still applied; because the Department had not supplied sufficient particulars of the evidence or afforded an effective hearing, the demand notices were invalid. The detention order, being consequential upon the invalid demand notice, could not stand independently and was also set aside. The writ petition therefore succeeded, with the impugned demand notices and detention order quashed.

Issues: (i) whether demand notices under Rule 9(2) of the Central Excise Rules, 1944 could be issued without first disclosing the material relied upon and giving the assessee an effective opportunity to meet the proposed conclusions; (ii) whether the detention order based on the impugned demand notice could survive if the demand notices were invalid.

Issue (i): whether demand notices under Rule 9(2) of the Central Excise Rules, 1944 could be issued without first disclosing the material relied upon and giving the assessee an effective opportunity to meet the proposed conclusions.

Analysis: The liability to pay excise duty under Rule 9(2) arose from a serious inquiry into alleged evasion and contravention of the statutory scheme governing manufacture, removal and recovery of duty. The Court treated such an inquiry as quasi-judicial in character, and even if regarded as administrative, it held that fair play and natural justice still required disclosure of the circumstances and evidence on which adverse conclusions were proposed. The material in the Department's possession had not been placed before the assessee with sufficient particulars and an effective opportunity to meet the inferences had not been afforded before the impugned notices were issued.

Conclusion: The demand notices were invalid and liable to be struck down for breach of natural justice.

Issue (ii): whether the detention order based on the impugned demand notice could survive if the demand notices were invalid.

Analysis: The detention order was consequential upon the demand notice dated June 17, 1964. Once the foundational demand notice was set aside, the consequential detention order could not stand independently.

Conclusion: The detention order also could not survive and was liable to be set aside.

Final Conclusion: The writ petition succeeded, the impugned excise demand notices and the consequential detention order were quashed, and the assessee obtained relief on the ground that the statutory demand process had been undertaken without the required hearing and disclosure.

Ratio Decidendi: Before an excise demand under Rule 9(2) is made on the basis of adverse material, the affected person must be informed of the full particulars of the charges and the evidence relied upon and must be given a real opportunity to meet those materials.
