Clarificatory excise amendment on meter length applies retrospectively, and departmental trade notice binds Revenue absent contrary instruction.

Notification No. 15/98-C.E. (N.T.) amending the definition of meter length under Rule 96ZI(6) was treated as clarificatory, because it explained that meter length for an embroidery machine means the distance between the first and last needles of only one roller; the amendment therefore operated retrospectively. The Baroda Collectorate Trade Notice on meter length computation was also treated as applicable and binding in the absence of any contrary Bangalore Collectorate instruction, so Revenue could not adopt a contrary interpretation. On that basis, the assessee's method of computation was sustained and the departmental appeal failed.

Issues: (i) whether the amendment made by Notification No. 15/98-C.E. (N.T.) to the definition of meter length under Rule 96ZI(6) was clarificatory and therefore retrospective; (ii) whether the Baroda Collectorate Trade Notice governing the meter length computation was applicable and binding in the facts of the case.

Issue (i): whether the amendment made by Notification No. 15/98-C.E. (N.T.) to the definition of meter length under Rule 96ZI(6) was clarificatory and therefore retrospective

Analysis: The amended definition stated that meter length in relation to an embroidery machine means the distance between the first and last needles of only one roller. The amendment was treated as a clarification of the earlier position and was linked to the Budget proposal explaining the intended method of computation. A clarificatory amendment of this nature was held to operate retrospectively.

Conclusion: The amendment was clarificatory in nature and applied retrospectively.

Issue (ii): whether the Baroda Collectorate Trade Notice governing the meter length computation was applicable and binding in the facts of the case

Analysis: The Trade Notice had been issued on the basis of departmental guidance regarding interpretation of the excise provisions. In the absence of any contrary instruction from the Bangalore Collectorate, it was treated as applicable. Revenue was not permitted to take a stand inconsistent with its own trade notice and departmental instructions.

Conclusion: The Trade Notice was binding and supported the assessee's position.

Final Conclusion: The departmental appeal failed because the computation adopted by the assessee was sustained on the basis of the clarificatory amendment and the applicable trade notice.

Ratio Decidendi: A clarificatory amendment explaining an existing statutory method of computation may operate retrospectively, and departmental trade notices issued for interpretation of the scheme bind the revenue unless displaced by a contrary instruction.
