The Calcutta High Court has reaffirmed the principle that an executing court is bound to enforce an arbitral award as rendered, without reinterpreting its terms - even where a party claims a clerical or computational error. This judgment underscores the finality of arbitral awards and the narrow scope of execution proceedings under the Arbitration and Conciliation Act, 1996.
Background & Facts
The Dispute
The dispute arose from a contractual disagreement between UK Mechanical Engineering Pvt. Ltd. (Award Holder) and Larsen & Toubro Ltd. (Award Debtor), which was referred to arbitration. The Sole Arbitrator, Justice Nadira Patherya (Retd), rendered an award on 19.09.2023, directing the Award Debtor to pay a principal sum, pre-award interest, and post-award interest.

The Award Holder seeks:
- Payment of outstanding pre-award interest of Rs. 9,05,739.70
- Further interest at 18% per annum on the outstanding amount from 19.02.2024 until realization
The Parties' Positions
- Award Holder: Argues the award is clear, final, and binding; the executing court must enforce it as written
- Award Debtor: Argues the reference to 01.07.2017 is a clerical error; interest should be computed from 01.07.2018; payment made in full based on corrected interpretation
The Legal Issue
Can an executing court under Section 36 of the Arbitration and Conciliation Act, 1996, reinterpret or correct the period for pre-award interest in an arbitral award on the ground of alleged typographical error, when no application for correction under Section 33 or challenge under Section 34 has been filed?
Arguments Presented
For the Appellant/Petitioner
The Award Holder contended that the arbitral award is a final and binding instrument under Section 36 of the Arbitration and Conciliation Act, 1996. The award explicitly states that pre-award interest is payable for the period from 01.07.2017 to 19.07.2019. The executing court has no jurisdiction to go behind the award or to substitute its own interpretation. The Award Debtor’s failure to seek correction under Section 33 or challenge under Section 34 renders the award conclusive. The shortfall in payment is a deliberate evasion, warranting further interest at 18% per annum.
For the Respondent/State
The Award Debtor argued that the reference to 01.07.2017 in the award is a typographical error, inconsistent with the reasoning and calculations elsewhere in the award, which indicate the correct starting date is 01.07.2018. Reliance was placed on a Chartered Accountant’s certificate to substantiate the corrected computation. The Debtor submitted that the payment made was in full compliance with the true intent of the award, and that permitting enforcement of the erroneous figure would result in unjust enrichment. The executing court, it was urged, should have the inherent power to prevent abuse and correct manifest errors.
The Court's Analysis
The Court emphasized that the scope of an executing court under Section 36 is strictly limited to enforcing the award as it stands. The court cannot act as an appellate or revisional forum, nor can it re-examine the merits of the award or correct perceived errors.
"The executing court is bound to execute the award as it stands and cannot vary, modify, or reinterpret its terms on merits."
The Court noted that the Arbitration and Conciliation Act, 1996, provides specific remedies for correcting errors: Section 33 permits the arbitral tribunal itself to correct clerical or computational mistakes, and Section 34 allows parties to challenge the award on limited grounds. Neither remedy was invoked by the Award Debtor. The award, therefore, attained finality.
The Court rejected the contention that the reference to 01.07.2017 was a typographical error, holding that even if such an error existed, it could not be rectified at the execution stage. To permit such a challenge would amount to a collateral attack on the award, which is legally impermissible.
"Permitting the Award Debtor to contend, at the stage of execution, that a portion of the Award is erroneous and requires correction would amount to a collateral challenge to the Award, which is impermissible in law."
Regarding the claim for 18% interest on the outstanding amount, the Court found that the shortfall arose from a bona fide dispute over interpretation - not wilful default. The Award Debtor had paid the principal and the majority of the interest, and the dispute was confined to a narrow component. The Court held that imposing punitive interest would be disproportionate and unjust.
The Verdict
The Award Holder succeeded in part. The Court directed the Award Debtor to pay the outstanding pre-award interest of Rs. 9,05,739.70 within four weeks from the date of the order. No further interest at 18% per annum was granted. The Execution Petition was disposed of with this direction.
What This Means For Similar Cases
Execution Courts Cannot Correct Arbitral Awards
- Practitioners must file applications under Section 33 for clerical corrections or Section 34 for setting aside awards within statutory timelines
- Any attempt to challenge the terms of an award during execution will be dismissed as a collateral attack
- The doctrine of finality under Section 36 is absolute unless corrected or set aside through prescribed remedies
Interest Claims Must Be Grounded in Award Terms
-
Claims for enhanced interest during execution require proof of deliberate default or contumacious conduct
-
Bona fide disputes over interpretation do not justify punitive interest rates
-
Courts will not penalize parties for good faith disagreements on award computation
-
Always verify the exact interest period and rate in the award before making partial payments
-
If an award contains an apparent error, file a Section 33 application immediately - do not wait for enforcement
-
Do not assume that partial payment of an award extinguishes liability for the balance unless the award is amended
