Duty-paid input requirement for exemption: nil-duty tea inputs do not satisfy Notification 193/86-C.E., and parity cannot cure error.

An exemption under Notification No. 193/86-C.E. is available only where the immediate raw material used in manufacture had actually suffered excise duty at the appropriate rate and no credit was taken; nil-duty or exempt inputs do not satisfy the condition that duty has "already been paid." The expression applies to the immediate input in the manufacturing chain, not to an earlier processing stage. The text also notes that a later circular cannot govern an earlier order, earlier instructions tied to a different notification have limited relevance, and a competitor's mistaken benefit does not create a claim of parity. The exemption claim therefore failed.

Issues: (i) Whether the benefit of Notification No. 193/86-C.E. was available to the finished tea packets where the immediate input was received after blending and the duty on the input was nil. (ii) Whether the Board circular dated 15 May 1995, the earlier instructions of 6 December 1980, or the grant of similar benefit to a competitor could compel allowance of the exemption.

Issue (i): Whether the benefit of Notification No. 193/86-C.E. was available to the finished tea packets where the immediate input was received after blending and the duty on the input was nil.

Analysis: The notification linked exemption to tea used in manufacture where duty on the input had already been paid and no credit had been taken. The Court applied the construction approved by the Constitution Bench in Dhiren Chemical Industries and held that "has already been paid" requires actual payment of excise duty at the appropriate rate. Goods on which no duty was payable or on which nil duty was charged cannot be treated as duty-paid goods for this purpose. The expression was held to refer to the immediate raw material supplied for manufacture, not to an earlier stage in the chain of processing.

Conclusion: The petitioners were not entitled to exemption under Notification No. 193/86-C.E. on the facts of the case.

Issue (ii): Whether the Board circular dated 15 May 1995, the earlier instructions of 6 December 1980, or the grant of similar benefit to a competitor could compel allowance of the exemption.

Analysis: The circular of 15 May 1995 was issued after the impugned order and could not control the legality of that order. The earlier instructions of 6 December 1980 were confined to a different notification and a different class of dyes, and were not a general interpretation of the phrase considered by the Court. The fact that a competitor was granted the benefit on an erroneous understanding did not create a right in favour of the petitioners, since there is no equality in illegality. The Court also held that the later constitutional-bench ruling prevailed over the earlier contrary view.

Conclusion: Neither the circulars nor the rival assessment entitled the petitioners to the exemption.

Final Conclusion: The exemption claim failed, the demand was upheld, and the petition was dismissed with the duty liability maintained.

Ratio Decidendi: An exemption notification requiring duty to have "already been paid" applies only where excise duty was in fact paid on the immediate raw material at the appropriate rate; nil-duty or exempt inputs do not satisfy that condition, and an erroneous benefit granted to another assessee cannot be claimed as a matter of equality.
