Editorial correction — 11 October 2026. The original 2023 note stated categorically that courts had no power to modify an arbitral award under sections 34 or 37. That proposition is no longer current. A five-judge Constitution Bench in Gayatri Balasamy v ISG Novasoft Technologies Ltd, 2025 INSC 605, held by a 4:1 majority that courts possess a limited modification power in the circumstances set out below. The note has been rebuilt around that controlling decision rather than silently deleting the earlier error.
Jurisdiction and scope: India; challenges to India-seated arbitral awards under sections 34 and 37 of the Arbitration and Conciliation Act, 1996. Enforcement of foreign awards and merits appeals are excluded. Law checked: 11 October 2026.
Short answer
A section 34 court is not a general appellate court and may not rewrite the award on the merits. But the absolute no-modification rule stated in Larsen Air Conditioning is no longer complete. Under the majority holding in Gayatri Balasamy, limited relief may include severing an invalid portion from a valid severable portion, correcting an evident clerical, computational or typographical error, and modifying post-award interest in an appropriate case. The Supreme Court retains its distinct Article 142 power, exercised cautiously.
When this applies
Use this note after receipt of an India-seated award when deciding whether the defect should be addressed by a section 33 request to the tribunal, an application under section 34, a request for adjournment and remission under section 34(4), or an appeal under section 37. The statutory time limit for section 34 remains three months from receipt of the award (or disposal of a section 33 request), with a possible further thirty days on sufficient cause, but not thereafter.
Steps
- Classify the defect before selecting the remedy. Separate a merits disagreement from an excess of jurisdiction, denial of proper notice or opportunity, public-policy ground, patent illegality in a domestic award, evident clerical or computational mistake, severable invalid part, or post-award-interest issue.
- Check section 33 first. A party may ordinarily ask the tribunal within thirty days of receipt to correct computation, clerical, typographical or similar errors; an interpretation requires party agreement. A section 33 request also affects the section 34 clock.
- Frame the section 34 ground narrowly. Identify the statutory clause relied on and the part of the record establishing it. Section 34 does not permit reappreciation of evidence or correction of every legal error.
- Ask whether the defective part is truly severable. Severance is available only where the valid part can stand independently. Do not ask the court to reconstruct a composite merits determination under the label of severance.
- Distinguish correction from merits revision. An evident computational, clerical, typographical or similar error may be corrected. A disputed factual or legal conclusion requiring a fresh merits exercise is not converted into such an error by describing it as obvious.
- Address post-award interest separately. The majority recognised a cautious power to increase or decrease post-award interest where compelling and well-founded reasons justify it. Plead the statutory benchmark, the award’s terms and the post-award facts said to require intervention.
- Consider section 34(4) remission. On a party’s request, the court may adjourn the challenge to let the tribunal resume proceedings or take action that may eliminate the ground for setting aside. Explain why remission, limited correction, severance or setting aside is the legally appropriate route.
- Preserve section 37 arguments. An appeal lies only from the orders specified in section 37. The appellate court’s power remains confined by the section 34 framework; it is not a rehearing of the arbitration.
Practical checklist
- Signed award and proof of the date of receipt
- Any section 33 request and the tribunal’s disposal
- Arbitration agreement, pleadings, procedural orders and relevant record
- Ground-by-ground section 34 table with record citations
- Exact proposed severance or correction, shown without rewriting the merits
- Interest calculation and post-award chronology where interest is challenged
- Application for section 34(4) remission, if appropriate
- Limitation calculation and any sufficient-cause affidavit for the additional thirty days
Common errors
- Repeating the pre-2025 proposition that modification is categorically unavailable.
- Treating section 34 as an appeal and rearguing evidence.
- Calling intertwined findings “severable” without showing the remainder can stand independently.
- Using the correction power to obtain a new merits outcome.
- Ignoring section 33 or the effect of a valid section 33 request on limitation.
- Assuming the additional thirty days is routinely available or extendable beyond its statutory ceiling.
