Prospective amendment to exemption notification and absence of suppression bar retrospective denial and extended limitation.

An amendment to an exemption notification is treated as prospective unless its language clearly requires retrospective operation, so the later restriction cannot be used to deny an exemption for waste yarn arising before the amendment date. The document also states that a demand for an earlier period is time-barred where the show cause notice contains no allegation of suppression of facts, because the extended limitation period cannot then be invoked. On that basis, the assessee's exemption claim and limitation objection both succeed for the disputed period.

Issues: (i) Whether the amended proviso to Notification No. 172/72-C.E. could be applied retrospectively so as to deny exemption to waste yarn arising before 03-02-1982; (ii) whether the demand for the earlier period was barred by time in the absence of an allegation of suppression of facts in the show cause notice.

Issue (i): Whether the amended proviso to Notification No. 172/72-C.E. could be applied retrospectively so as to deny exemption to waste yarn arising before 03-02-1982.

Analysis: The exemption under the notification was held to be governed by its pre-amendment text for the period prior to the amendment. The later restriction introduced on 03-02-1982 was treated as prospective and not as operating backwards to periods already covered. On that basis, the waste yarn in question could not be denied the benefit of exemption merely by applying the amended proviso to an earlier period.

Conclusion: The issue was decided in favour of the assessee and against the Revenue.

Issue (ii): Whether the demand for the earlier period was barred by time in the absence of an allegation of suppression of facts in the show cause notice.

Analysis: The demand related to a period long prior to the notice, and the notice did not contain an allegation of suppression of facts. In such circumstances, the extended period could not be invoked, and the demand for the relevant period was time-barred.

Conclusion: The issue was decided in favour of the assessee and against the Revenue.

Final Conclusion: The exemption was held available for the disputed period and the time-bar objection also succeeded, resulting in relief to the assessees in both appeals.

Ratio Decidendi: An amendment to an exemption notification cannot be applied retrospectively to deny a benefit for an earlier period unless the language clearly so provides, and the extended period of limitation cannot be invoked without a specific allegation of suppression in the show cause notice.
