Exemption notification amendment limited only to prior clause (a) beneficiaries; prior clause (b) users were not disqualified.

Notification No. 175/86 created distinct eligibility routes under clause (a) and clause (b) of the first proviso. The amendment introduced by Notification No. 55/92 restricted future exemption only for manufacturers who had earlier availed benefit under clause (a), and the bar could not be extended to those who had availed exemption under clause (b). Mere excess of preceding-year clearances beyond the monetary limit did not, by itself, attract the amended disqualification. The exemption therefore remained available to manufacturers outside the class targeted by the amendment.

Issues: Whether the assessees were disentitled to the benefit of exemption Notification No. 175/86 for the period 1-4-1992 to 21-5-1992 by reason of the amendment introduced by Notification No. 55/92, merely because their clearances in the preceding year exceeded the monetary limit, even though they had earlier availed of the exemption under clause (b) of the first proviso and not under clause (a).

Analysis: Paragraph 4 of Notification No. 175/86, as it stood before amendment, created two distinct routes affecting eligibility. Clause (a) of the first proviso dealt with units whose clearances did not exceed the prescribed monetary limit, while clause (b) dealt with manufacturers availing exemption in the specified circumstances. The amended second proviso introduced by Notification No. 55/92 restricted future entitlement only for manufacturers who had earlier availed exemption in pursuance of clause (a). The monetary limit by itself did not attract the amended disqualification, because the amendment did not alter clause (a) and did not extend the bar to manufacturers who had earlier availed exemption under clause (b). The departmental challenge ignored this distinction. The interpretation adopted in the impugned order was supported by the more apposite prior decision that examined the precise effect of the amendment.

Conclusion: The assessees were not hit by Notification No. 55/92 merely because their preceding-year clearances exceeded Rs. 7.50 lakhs, since their earlier exemption was under clause (b) and not clause (a); the exemption remained available.

Ratio Decidendi: An amendment to an exemption notification withdrawing future benefit only from a defined class of past beneficiaries must be confined to that class, and eligibility cannot be denied by importing a condition that the amendment did not alter or extend.
