I. Introduction: Finality as the First Principle of Arbitration
Arbitration is chosen precisely because it promises what litigation often cannot: a swift, final, and commercially sensible resolution rendered by a tribunal of the parties’ own choosing. That promise would be illusory if every award were vulnerable to a fresh trial on the merits before a court. The Arbitration and Conciliation Act, 1996 (“the 1996 Act”), modelled on the UNCITRAL Model Law, therefore confines judicial interference with an award to a closed and exhaustive list of grounds set out in Section 34. The provision does not create an appeal; it creates a supervisory jurisdiction of last resort, exercisable only where the arbitral process or its outcome offends specific, narrowly defined standards.
The jurisprudence under Section 34 is, in substance, the story of Indian courts repeatedly resisting—and occasionally succumbing to—the temptation to expand this narrow gate into a wider avenue of appellate review. This treatise traces that doctrinal arc: from the statutory text, through the landmark decisions that have defined “public policy” and “patent illegality,” to the most recent five-judge pronouncement on whether a court may modify, rather than merely set aside, a flawed award.
II. The Statutory Architecture of Section 34
Section 34(1) permits recourse to a court against an arbitral award “only by an application for setting aside such award in accordance with subsection (2) and subsection (3).” ” The grounds are exhaustively enumerated in two limbs:
A. Section 34(2)(a) — Grounds Requiring Proof by the Party Challenging the Award
- Incapacity of a party to the arbitration agreement;
- Invalidity of the arbitration agreement under the law to which the parties have subjected it;
- Absence of proper notice of appointment of the arbitrator or of the arbitral proceedings, or inability of a party otherwise to present its case;
- The award dealing with a dispute not contemplated by, or not falling within the terms of, the submission to arbitration, or containing decisions on matters beyond the scope of the submission (subject to severability under the proviso);
- Improper composition of the arbitral tribunal or non-compliance with the agreed arbitral procedure.
B. Section 34(2)(b)—Grounds the Court May Examine Suo Motu
- The subject matter of the dispute is not capable of settlement by arbitration under the law for the time being in force; or
- The arbitral award is in conflict with the “public policy of India.”
C. Section 34(2A) — Patent Illegality (Domestic Awards Only)
Inserted by the Arbitration and Conciliation (Amendment) Act, 2015, this sub-section permits an additional ground for purely domestic awards: that the award is vitiated by “patent illegality appearing on the face of the award,” subject to the express proviso that an award shall not be set aside merely on the ground of an erroneous application of the law or by reappreciation of evidence. Critically, this ground is unavailable to international commercial arbitrations seated in India.
D. Section 34(3)—Limitation
An application under Section 34 must be made within three months from the date on which the party making the application received the arbitral award, extendable by a further thirty days on sufficient cause being shown—but not thereafter. The Explanation to Section 34(1) also obliges the applicant to establish the grounds “on the basis of the record of the arbitral tribunal,” underscoring that Section 34 proceedings are not an occasion for fresh evidence.
III. The Procedural and Jurisdictional Grounds — Section 34(2)(a)
The grounds under Section 34(2)(a) mirror Article V(1) of the New York Convention and Article 34(2)(a) of the UNCITRAL Model Law. They are largely uncontroversial in principle, though fact-intensive in application. The ground most frequently invoked in practice is denial of a fair hearing—a party’s inability to present its case, whether through inadequate notice, refusal of an adjournment, or reliance by the tribunal on material not put to the parties.
Delhi Airport Metro Express Pvt. Ltd. v. Delhi Metro Rail Corporation Ltd. [(2022) 1 SCC 131]
The Supreme Court set aside an award of over ₹2,782 crore, holding that the tribunal’s approach to termination under the Concession Agreement disclosed patent illegality and a failure to consider vital evidence and contractual terms central to the dispute. The judgment is frequently cited for its emphatic restatement that a court exercising Section 34 jurisdiction cannot reappreciate evidence or substitute its own view merely because another view of the contract is possible—the threshold is breach that goes to the root of the matter, not a disagreement on interpretation.
Severability under the proviso to Section 34(2)(a)(iv) allows a court to sever and uphold the part of the award dealing with matters properly submitted to arbitration, while setting aside only the excess. This proviso has since assumed outsized importance as the textual anchor for the Supreme Court’s 2025 recognition of a limited modification power, discussed in Part IX below.
IV. Non-Arbitrability and Public Policy — Section 34(2) (b)
Unlike the grounds in clause (a), which must be pleaded and proved by the challenging party, the grounds in clause (b) — non-arbitrability of the subject matter and conflict with public policy — may be examined by the court on its own motion, reflecting their character as matters touching the public interest rather than purely private grievance.
Vidya Drolia v. Durga Trading Corporation [(2021) 2 SCC 1]
A three-judge Bench reformulated the test for non-arbitrability, holding that a subject matter is non-arbitrable where the dispute concerns actions in rem rather than subordinate rights in personam, has an erga omnes effect on third parties, relates to the sovereign or inalienable functions of the State, or is expressly or by necessary implication reserved for adjudication by specified courts or tribunals under a statutory scheme. The Court also overruled the earlier position in N. Radhakrishnan v. Maestro Engineers, holding that allegations of fraud are, without more, no longer a bar to arbitrability, and clarified that landlord-tenant disputes under the Transfer of Property Act — being actions in personam — are arbitrable.
V. The Long March of “Public Policy”: Renusagar to Ssangyong
No phrase in Indian arbitration law has travelled further, or more controversially, than “public policy of India.” Its meaning has been narrowed, widened, and narrowed again across four decades of jurisprudence and one legislative amendment.
A. Renusagar (1994) — The Narrow Foundation
Renusagar Power Co. Ltd. v. General Electric Co. [AIR 1994 SC 860]
Interpreting the analogous provision in the Foreign Awards (Recognition and Enforcement) Act, 1961, a Constitution Bench held that resisting enforcement of a foreign award on public-policy grounds required something more than a mere violation of Indian law. Enforcement could be refused only if it was contrary to:
- the fundamental policy of Indian law;
- the interests of India; or
- justice or morality.
“…fundamental policy of Indian law; or… the interests of India; or… justice or morality.”
— Renusagar Power Co. Ltd. v. General Electric Co., AIR 1994 SC 860, para 66
B. Saw Pipes (2003) — The Expansive Turn
The Supreme Court held that the term “public policy of India” used in the domestic setting-aside context of Section 34 need not carry the same narrow, private-international-law meaning it bears under Renusagar. The Court added a fourth head—”patent illegality”—reasoning ” — reasoning that an award contrary to the substantive provisions of law, or in contravention of the Act itself, or in conflict with the terms of the contract, could be set aside as opposed to India’s public policy. This decision considerably widened the scope of judicial intervention and, for over a decade, invited exactly the merits review that Section 34 was designed to foreclose.
C. Western Geco (2014)—A Further Widening
The Court read into “fundamental policy of Indian law” three additional juristic principles said to be inherent in Indian jurisprudence: the duty of a quasi-judicial authority to adopt a judicial approach, compliance with natural justice, and a decision that is not perverse or irrational — that is, one that no reasonable person could have reached (a Wednesbury-style standard imported from administrative law). This further blurred the line between review for illegality and review on the merits.
D. The 2015 Amendment and Ssangyong (2019) — Course Correction
The Arbitration and Conciliation (Amendment) Act, 2015, legislatively reversed Saw Pipes and Western Geco for the public-policy ground, restricting “fundamental policy of Indian law” so that it no longer permits a review on the merits and confining “justice or morality” to the most basic notions of the terms. “Patent illegality” was relocated to a distinct subsection, 34(2A), available only for purely domestic awards.
Ssangyong Engineering & Construction Co. Ltd. v. National Highways Authority of India [(2019) 15 SCC 131]
The Supreme Court gave the amended provision its authoritative construction, holding that the broad Western Geco interpretation of “fundamental policy of Indian law” no longer survives under the amended Section 34. The Court held that patent illegality, to justify interference, must go to the root of the matter; an illegality of a trivial nature would not attract Section 34(2A). On facts, the majority award—which had unilaterally substituted a new price-variation formula not agreed upon between the parties, in effect rewriting the contract—was set aside as patently illegal and contrary to the fundamental policy of Indian law, and the Court exercised its Article 142 power to give effect to the minority award instead of remitting the matter.
“Illegality must go to the root of the matter…”
— Ssangyong Engg. & Construction Co. Ltd. v. NHAI, (2019) 15 SCC 131, para 31 (quoting the Amendment Act’s Statement of Objects)
E. Shri Lal Mahal — Bifurcating Domestic and Foreign Awards
Shri Lal Mahal Ltd. v. Progetto Grano SpA [(2014) 2 SCC 433]
The Court held that the expansive Saw Pipes construction of public policy could not be transplanted into Section 48, which governs enforcement of foreign awards; the narrower Renusagar standard continues to apply there. This bifurcation between domestic and foreign/international-commercial awards remains a structural feature of the post-2015 regime and was carried forward in Ssangyong.
VI. Patent Illegality — The Domestic-Award-Only Ground
Section 34(2A) is available only to purely domestic awards—arbitrations that are neither international commercial arbitrations nor awards rendered under Part II. Its content was substantially pre-figured by the Supreme Court’s own analysis in Associate Builders, decided shortly before the 2015 Amendment came into force, and subsequently harmonized with the amended text in Ssangyong.
Associate Builders v. Delhi Development Authority (2015)
Associate Builders v. Delhi Development Authority [(2015) 3 SCC 49]
Considering a pre-amendment challenge, the Court laid down a structured taxonomy for patent illegality:
- A finding based on no evidence at all, or one that ignores vital evidence, is perverse and liable to be set aside;
- a finding based on documents taken behind the back of the parties similarly offends natural justice; and
- An arbitrator’s construction of a contract will be interfered with only where no fair-minded or reasonable person could have arrived at it—that is, where the view taken is not even a possible view.
courtThe Court cautioned that a mere erroneous application of law, or an interpretation with which the court disagrees, is not sufficient.
“…a finding based on no evidence at all… would be perverse…”
— Associate Builders v. DDA, (2015) 3 SCC 49, para 33 (as extracted in subsequent Supreme Court decisions, including State of Chhattisgarh v. Sal Udyog (P) Ltd.)
UHL Power Co. Ltd. v. State of Himachal Pradesh (2022)
UHL Power Co. Ltd. v. State of Himachal Pradesh [(2022) 4 SCC 116]
Reinforcing the limited scope of review, the Court held that a Section 34 court does not sit in appeal over the arbitral tribunal and that the existence of an alternative, equally plausible view on the facts or on contractual interpretation is not, by itself, a ground for setting aside the award.
isRead together, these decisions distill a workable test: patent illegality requires an error that is:
- apparent on the face of the award without a need for the court to reappreciate evidence;
- not merely an erroneous application of law; and
- sufficiently grave that it goes to the root of the matter rather than being of a trivial or peripheral character.
VII. What Section 34 Is Not: The Bar on Merits Review
A recurring thread across every leading decision—Renusagar, Saw Pipes itself, Associate Builders, Ssangyong, Delhi Airport Metro Express, and UHL Power—is the insistence that Section 34 is not a first appeal. The court cannot:
- Reappreciate evidence already considered by the tribunal;
- Substitute its own interpretation of the contract for a plausible interpretation adopted by the tribunal;
- Correct an error of law that does not go to the root of the matter; or
- Set aside an award merely because it disagrees with the tribunal’s conclusion on facts.
This self-denying posture is what preserves the commercial utility of arbitration. A regime in which every award is effectively re-litigated before a court on its merits defeats the object of Section 5 of the 1996 Act, which bars judicial intervention except as “provided in this Part”—a provision the Supreme Court has repeatedly invoked to police the boundaries of Section 34 itself. “`
VIII. Limitation Under Section 34(3)
Section 34(3) prescribes a strict three-month period, running from the date of receipt of the award (or, where a request under Section 33 for correction/interpretation has been made, from the date that request is disposed of), with a further condonable window of thirty days on sufficient cause. The proviso’s language — “but not thereafter” — has been read by the Supreme Court as excluding the general condonation power under Section 5 of the Limitation Act, 1963, making this among the strictest limitation regimes in Indian procedural law. Practitioners must calendar the receipt date of the award with precision, since the thirty-day grace period is itself subject to a “sufficient cause” standard and is not available as of right.
IX. Set Aside or Modify? The Hakeem–Balasamy Fault Line
For a quarter-century, the settled position was that a Section 34 court possesses only the power to set aside an award (wholly or, under the severability proviso, in part) — never to vary, enhance, or otherwise rewrite its terms. The remedy for an infirm award was annulment, leaving the parties to arbitrate afresh if they wished.
Project Director, NHAI v. M. Hakeem [(2021) 9 SCC 1]
The Supreme Court held that Section 34 does not clothe a court with any power to modify an award—including to enhance compensation in land-acquisition arbitrations—and that the 1996 Act’s deliberate omission of the modification power available under the predecessor 1940 Act was a considered legislative choice. Citing McDermott International Inc. v. Burn Standard Co. Ltd., (2006) 11 SCC 181, the Court reiterated that the 1996 Act confines courts to a supervisory, fairness-oriented review, not an appellate one.
Gayatri Balasamy v. ISG Novasoft Technologies Ltd. [2025 SCC OnLine SC 986]
A five-judge Constitution Bench, by a 4:1 majority (Sanjiv Khanna, C.J., with B.R. Gavai, Sanjay Kumar and Augustine George Masih, JJ.; K.V. Viswanathan, J. dissenting), revisited Hakeem and held that the power to set aside an award under Section 34 inherently carries within it a narrower, structurally limited power to modify the award — but only where the offending portion is severable, both legally and practically, from the valid remainder, consistent with the proviso to Section 34(2)(a)(iv). The majority also recognized a residual power to correct clerical, computational, or typographical errors and to adjust post-award interest under Section 31(7)(b) where the rate fixed by the tribunal is manifestly unjustified in light of subsequent events. Justice Viswanathan’s dissent maintained the Hakeem position, distinguishing severance—separating the bad from the good—from modification—rewriting the award—and cautioning that blurring the two erodes the finality the 1996 Act was designed to protect.
Practitioners should treat Balasamy as narrowing, not overruling. Hakeem: the default remedy under Section 34 remains setting aside, and any modification must be justified by clean severability rather than treated as a general appellate power to recompute an award to the court’s own satisfaction.

XI. Practitioner’s Checklist Before Filing (or Resisting) a Section 34 Application
- Confirm the date of receipt of the signed award and calendar the three-month limitation period under Section 34(3), plus the outer thirty-day condonable window.
- Identify whether the award is a purely domestic award, a domestic award in an international commercial arbitration, or a foreign award — this determines whether Section 34(2A) (patent illegality) is even available.
- Frame the challenge strictly within the closed grounds of Section 34(2)(a), (2)(b), and, if applicable, (2A)—avoid pleadings that read as a disguised appeal on the merits.
- For a public-policy challenge, plead specifically under one of the three post-2015 heads: fundamental policy of Indian law, or the most basic notions of justice or morality—the “interests of India” ground has been legislatively deleted for this purpose.
- For a patent-illegality challenge, be prepared to show the illegality is apparent on the face of the award and goes to the root of the matter—not a mere erroneous application of law or an alternative possible interpretation of the contract.
- Anchor factual grounds strictly to the arbitral record, per the Explanation to Section 34(1); Section 34 is not an occasion to lead fresh evidence.
- Where only part of the award is infirm, consider pleading severability under the proviso to Section 34(2)(a)(iv) and, post-Balasamy, whether a structured modification remedy (rather than wholesale annulment) is realistically available.
Verify every citation against the certified copy or an authoritative reporter before filing; do not rely on secondary summaries for the operative paragraph numbers.
XII. Conclusion
The trajectory of Section 34 jurisprudence — narrow in Renusagar, wide in Saw Pipes and Western Geco, narrowed again by the 2015 Amendment and Ssangyong, and now cautiously reopened on the question of modification by Gayatri Balasamy — reflects a continuing negotiation between two legitimate but competing values: the finality that makes arbitration commercially useful, and the residual judicial duty to correct awards that are procedurally unfair, jurisdictionally overreaching, or substantively shocking to the conscience.
The settled doctrinal core, however, has held firm across three decades: Section 34 is not an appeal; courts may not reappreciate evidence or prefer their own view of the contract, and interference is reserved for illegality that goes to the root of the matter.
Counsel advising on a Section 34 challenge — whether prosecuting or resisting one — must therefore build the case not on the perceived unfairness of the outcome, but on its precise fit within this narrow, closely guarded gate.
