The Central Excise and Service Tax Appellate Tribunal, Chandigarh Regional Bench, has clarified a critical principle in refund jurisprudence under the Central Excise Act: once a refund amount is sanctioned by an adjudicating authority and the revenue does not appeal against its quantum, that figure attains finality and cannot be reopened by lower authorities even in implementation of a higher court order. This decision resolves a recurring procedural conflict between taxpayers and tax authorities over the re-assessment of Cenvat Credit deductions.
Background & Facts
The Dispute
M/s ACC Limited and M/s Ambuja Cement Limited, both cement manufacturers in Himachal Pradesh, claimed refunds of Central Excise duties paid on clinker that was subsequently used captively in the manufacture of exempted cement. They had deposited amounts under protest during litigation, seeking exemption under Notification No. 50/2003-CE and later, entitlement to Cenvat Credit on inputs used for captive clinker production under Notification No. 67/95-CE. The Supreme Court, by its order dated 21.08.2015, upheld their entitlement to the exemption and, by implication, to the refund of pre-deposited duties.
Key Facts
- Both appellants manufactured clinker, part of which was cleared on payment of duty, and the balance used captively for cement production.
- They availed Cenvat Credit on inputs and input services used in clinker manufacture.
- Refund claims were filed after the Supreme Court’s 2015 ruling.
- Deputy/Assistant Commissioners, by orders dated 16.09.2016 (ACC Ltd) and 15.09.2016 (Ambuja Cement), sanctioned refunds of Rs. 652,41,66,464 and Rs. 191,09,14,680 respectively.
- These orders deducted Cenvat Credit amounts: Rs. 39,44,73,881 for ACC Ltd and Rs. 11,23,89,005 (Cenvat Credit + Rs. 7,09,43,635 interest) for Ambuja Cement.
- The refunds were ordered to be credited to the Consumer Welfare Fund on grounds of unjust enrichment.
- Appellants appealed against the crediting of refunds to the Consumer Welfare Fund, not against the quantum of refund.
- CESTAT, by its order dated 01.07.2024, held that unjust enrichment did not apply and directed payment of the sanctioned refund amounts to the appellants.
- Despite this, the Assistant Commissioner, by impugned orders dated 26.12.2024 (ACC) and 27.11.2024 (Ambuja), increased the Cenvat Credit deduction to Rs. 55,00,39,624 and Rs. 12,81,28,016 respectively, reducing the refund amounts.

The Parties' Positions
For the Appellants: The refund amounts sanctioned in 2016, after verification and with explicit agreement on Cenvat Credit deduction, attained finality due to non-appeal by revenue. The CESTAT’s 2024 order directed implementation of the 2016 quantum, not its re-quantification. Increasing the deduction was legally impermissible and procedurally abusive.
For the Respondent: The CESTAT’s 2024 order required deduction of Cenvat Credit, and the lower authority merely implemented it correctly. The original 2016 deductions were allegedly miscalculated, and the revised figures were based on ER-1 returns and verification.
Relief Sought
The appellants sought: (1) setting aside of the impugned orders dated 26.12.2024 and 27.11.2024; (2) restoration of the refund amounts as sanctioned in 2016 - Rs. 652,41,66,464 for ACC Ltd and Rs. 191,09,14,680 for Ambuja Cement; (3) immediate payment of these amounts with interest, pending resolution of interest claims before the Himachal Pradesh High Court.
The Legal Issue
Can the revenue authority, after failing to appeal against a refund order that includes a specific deduction of Cenvat Credit, subsequently increase that deduction during implementation of a higher tribunal’s order directing payment of the sanctioned refund?
Arguments Presented
For the Appellant
Shri J.C. Patel, Advocate, relied on Nokia India Sales P. Ltd v CC (2024) 25 Centax 293, Objects D' Art India (2016) 344 ELT 569, Ma Care (2017) 358 ELT 451, and ABB Ltd v CC (2005) 181 ELT 71. He argued that when the revenue does not challenge the quantum of refund in an appeal, that figure becomes final between the parties. The CESTAT’s 2024 order did not direct re-calculation of Cenvat Credit; it merely affirmed that the already-deducted amount should not be refunded. The revenue’s attempt to increase the deduction was an impermissible collateral attack on a final order.
For the Respondent
Ms. Amita Gupta, Authorized Representative, contended that the CESTAT’s order required deduction of Cenvat Credit, and the lower authority was merely ensuring compliance. She argued that the original 2016 deductions were based on incomplete data and that the revised figures, derived from ER-1 returns, were more accurate. She maintained that the revenue had a right to correct errors even in implementation.
The Court's Analysis
The Tribunal undertook a meticulous review of its own 2024 order and the 2016 sanctioning orders. It emphasized that the operative part of its 2024 order stated: "refund as at (i) above, be granted after deducting the Cenvat Credit availed by them on the inputs used in the manufacture of Clinker, during the period in dispute." This was not a direction to re-calculate or re-determine the credit, but a clarification that the appellants were not entitled to a refund of the Cenvat Credit already availed.
"We find that it is nowhere specified in the order that Cenvat credit should be deducted again even if it has been deducted while arriving at the refundable amount in the orders passed in 2016. Such an interpretation is bereft of any legal backing and in addition would be defeating the spirit of the justice."
The Tribunal noted that the 2016 orders were not appealed by the revenue, despite being detailed, verified by jurisdictional officers, and accepted by the appellants. The Assistant Commissioner had explicitly recorded that the Cenvat Credit deductions were based on TR-6/GAR7 challans, PLA debits, and the appellants’ own submissions. The Tribunal cited Nokia India Sales and Indian Farmers Fertilizers to affirm that finality of an order arises when the revenue does not challenge it, and such finality cannot be diluted by a subsequent judgment.
"Once the department allowed a particular issue to attain finality, it will not be permissible to permit the department in appellate proceedings initiated by an assessee before the Tribunal to raise this issue, even if it be a legal issue."
The Tribunal rejected the revenue’s argument that it was merely "implementing" the 2024 order. It held that implementation meant executing the quantum already determined and finalized - not reopening it. The revenue’s failure to appeal the 2016 orders precluded it from later challenging the deduction amount, even if it believed the figure was erroneous.
The Verdict
The appeals were allowed. The impugned orders dated 26.12.2024 and 27.11.2024 were set aside. The refund amounts sanctioned in 2016 - Rs. 652,41,66,464 for M/s ACC Limited and Rs. 191,09,14,680 for M/s Ambuja Cement Limited - were restored. The revenue was directed to pay these amounts to the appellants within 6 weeks from the date of the order. The issue of interest on delayed refund was held to be sub judice before the Himachal Pradesh High Court and was not adjudicated.
What This Means For Similar Cases
Finality of Refund Orders Is Absolute
- Practitioners must assert finality when revenue attempts to re-open quantified refunds after non-appeal.
- Any attempt by revenue to revise Cenvat Credit deductions post-final order is procedurally invalid.
- The burden shifts to revenue to challenge refund quantum at the earliest opportunity - failure to appeal waives the right to contest it later.
Cenvat Credit Deductions Cannot Be Reassessed Post-Final Order
- Once a taxpayer agrees to a Cenvat Credit deduction in a refund order and the revenue does not appeal, that deduction becomes binding.
- Subsequent orders cannot increase the deduction unless the original order is set aside through proper appeal.
- ER-1 returns or revised calculations cannot override a final order unless the order itself is challenged.
Strategic Implications for Tax Litigation
- Taxpayers should explicitly record agreement to Cenvat Credit deductions in writing during refund proceedings.
- Revenue authorities must file appeals against refund quantification within the statutory period - delay or inaction constitutes acquiescence.
- In appeals against crediting refunds to Consumer Welfare Fund, taxpayers should not concede to re-quantification as a condition of relief.
