Excise exemption claims must first be tested before statutory authorities when classification and factual activity are in dispute.

Writ jurisdiction was held inappropriate where excise duty liability and exemption claims depended on the factual nature of the petitioners' body-building activity and the correct classification under the excise framework. The approved classification lists continued to operate, and the petitioners had not first sought modification or reclassification before the competent excise authorities. The authorities were the proper forum to assess the factual and legal basis of any exemption claim under the statutory procedure. Direct challenge in writ proceedings was therefore premature, and the petitions were treated as misconceived at that stage.

Issues: Whether the writ petitions challenging excise duty liability and exemption claims were maintainable at the threshold, or whether the petitioners were first required to seek modification or reclassification before the competent excise authorities.

Analysis: The petitions concerned bodies built on chassis supplied by customers, and the dispute turned on the factual nature of each petitioner's activity and the corresponding classification under the excise framework. The Court accepted the respondents' stand that the approved classification lists remained in force, that the petitioners had not first sought modification or reclassification before the statutory authorities, and that the authorities were the proper forum to examine the factual and legal basis of any exemption claim. In these circumstances, direct resort to writ jurisdiction was held to be inappropriate because the eligibility question required initial scrutiny by the competent authorities under the statutory procedure.

Conclusion: The writ petitions were premature and misconceived, and were not maintainable at that stage.
