Conditional excise exemption for complex fertilizers failed where statutory requirements were not fully satisfied, defeating the refund claim.

Complex fertilizers were held outside Notification No. 25/70-C.X because the exemption covered only mixed fertilizers manufactured with power from two or more duty-paid fertilizers, not products involving additional ingredients and chemical reactions. The Central Government's revisional order was treated as conditional, not as an absolute grant of exemption, and the respondent therefore remained ineligible for relief. As the exemption was not legally available, the claimed refund of excise duty also failed, and repayment was further resisted on the ground of unjust enrichment. The departmental refusal of exemption and refund was upheld.

Issues: (i) Whether the complex fertilizers manufactured by the respondent were entitled to exemption under Notification No. 25/70-C.X dated 1-3-1970. (ii) Whether the respondent was entitled to refund of excise duty already collected, in view of the earlier governmental and departmental orders and the plea of unjust enrichment.

Issue (i): Whether the complex fertilizers manufactured by the respondent were entitled to exemption under Notification No. 25/70-C.X dated 1-3-1970.

Analysis: The exemption applied only to mixed fertilizers manufactured with the aid of power from two or more fertilizers on which appropriate duty or countervailing duty had already been paid. The Court followed the Supreme Court's construction of the notification and held that the benefit could not extend to products whose manufacture involved other ingredients and chemical reactions beyond a mere mixture of duty-paid fertilizers. The Central Government's revisional order did not conclusively grant exemption in absolute terms, but made it conditional upon fulfilment of the notification's requirements.

Conclusion: The respondent was not entitled to exemption under the notification.

Issue (ii): Whether the respondent was entitled to refund of excise duty already collected, in view of the earlier governmental and departmental orders and the plea of unjust enrichment.

Analysis: The earlier order of the Central Government did not finally foreclose fresh consideration by the excise authorities, and the Assistant Collector's initial exemption order was found to have proceeded on a mistaken assumption. Since the respondent was not legally entitled to the exemption, refund could not be sustained. The Court also accepted the revenue's objection that repayment would result in unjust enrichment, and therefore the writ of mandamus for refund was not maintainable on the facts.

Conclusion: The respondent was not entitled to refund of the excise duty.

Final Conclusion: The writ appeals succeeded, the respondent's writ petitions failed, and the departmental order denying exemption and refund was upheld.

Ratio Decidendi: A conditional or qualified revisional order does not finally grant exemption unless the statutory conditions are actually satisfied, and refund of duty cannot be ordered where the assessee is not legally entitled to the exemption and repayment would unjustly enrich it.
