Sales tax classification of leaf springs turns on inherent nature and common parlance, not purchaser use, under the residual entry.

Maintainability was upheld because the applicants were not parties to the original determination and could not effectively challenge it through later assessment remedies, while subordinate authorities remained bound by that determination. Leaf springs were classified by their inherent nature and common parlance meaning, not by the purchaser's end use, and were found not to be exclusively motor vehicle parts. As no specific entry covered leaf springs and the notification reserved only a motor vehicle parts entry, the goods fell within the residual category and were taxable at the general rate. The impugned determination and consequential proceedings were set aside.

Issues: (i) Whether the application before the Tribunal was maintainable despite the availability of statutory remedies against assessments made pursuant to the impugned determination; (ii) Whether leaf springs fell under the motor vehicle parts entry or under the residual entry in the relevant sales tax notification.

Issue (i): Maintainability of the application before the Tribunal.

Analysis: The determination under section 12A of the Rajasthan Sales Tax Act, 1954 was appealable, but the applicants were not parties to the proceedings before the Additional Commissioner and therefore could not effectively invoke the ordinary appellate remedy against the impugned determination. The later assessment remedies could not cure the grievance because the impugned order itself could not be challenged in those proceedings and subordinate authorities were bound by the determination. The preliminary objection was therefore untenable.

Conclusion: The application was maintainable and the preliminary objection was rejected.

Issue (ii): Classification of leaf springs under the relevant notification.

Analysis: The impugned determination treated leaf springs as motor vehicle parts, but it gave no reasons and did not distinguish the earlier binding departmental decision that laminated springs were neither iron and steel nor motor parts. Leaf springs are used in several kinds of vehicles and are not exclusively adapted for motor vehicles. For sales tax classification, the use to which a customer puts the goods is not decisive; the character of the goods must be determined by their inherent nature and common parlance meaning. As the notification specifically listed motor vehicle parts but contained no distinct entry for leaf springs, and the goods were not covered by any other specific entry, the goods fell within the residual category.

Conclusion: Leaf springs were not exigible as motor vehicle parts and were taxable under the residual entry at the general rate.

Final Conclusion: The impugned determination and consequential proceedings were set aside, and leaf springs were held taxable at the general rate under the residual entry rather than as motor vehicle parts.

Ratio Decidendi: For sales tax classification, the inherent nature and common parlance identity of the goods govern, and the end use by a particular purchaser does not determine classification where the goods are capable of multiple uses and are not covered by a specific entry.
