Factual Background

DMRC is a state-owned company wholly owned by the Government of India and the National Capital Territory of Delhi. DAMEPL (Delhi Airport Metro Express Private Limited) is a special purpose vehicle incorporated by a consortium of Reliance Infrastructure Limited and Construcciones Y Auxiliar de Ferrocarriles SA, Spain.

In 2008, the parties entered into a Concession Agreement envisaging a public-private partnership for providing metro rail connectivity between New Delhi Railway Station and the Indira Gandhi International Airport. Under the agreement, DMRC was to undertake clearances, land acquisition, and civil structures, while DAMEPL was to design, supply, install, test, and commission railway systems. DAMEPL was to complete the work in two years and maintain the Airport Metro Express Line (AMEL) until August 2038.

In April 2012, DAMEPL sought deferment of the concession fee, citing delays — notably stating that AMEL had been "running without a glitch since 23 February 2011." The Ministry of Urban Development convened a stakeholders' meeting in July 2012, and a Joint Inspection Committee was constituted to inspect alleged defects.

On 8 July 2012, DAMEPL halted operations, alleging the line was unsafe. On 9 July 2012, DAMEPL issued a Cure Notice containing a "non-exhaustive" list of eight defects allegedly attributable to faulty construction and deficient designs. DMRC was given 90 days to cure the defects. On 8 October 2012, DAMEPL issued a Termination Notice, stating the defects had not been cured within the cure period.

A critical fact: on 19 November 2012, both parties made a joint application to the Commissioner of Metro Railway Safety (CMRS) for reopening AMEL. The joint application, signed by representatives of both DMRC and DAMEPL, stated that repairs had been inspected by an independent engineer (M/s TUV), that SYSTRA (the original design consultant) had concluded there was "no effect on the integrity of the girders," and that train trials "after repairs by DMRC have been completed successfully and all systems have been checked for correct functioning at various speeds including at speed of 120 kmph."

On 18 January 2013, the CMRS issued sanction for reopening, subject to speed restrictions (starting at 50 kmph, progressively increasing). Operations resumed on 22 January 2013. On 30 June 2013, DAMEPL handed over the project assets to DMRC. DMRC has operated AMEL since 1 July 2013 — the line was progressively cleared for 60, 80, 90, 100, 110, and ultimately 120 kmph.

The Arbitral Award

In August 2013, a three-member Tribunal comprising Mr. A.P. Mishra, Mr. S.S. Khurana, and Mr. H.L. Bajaj was constituted. After 68 hearings and consideration of 35,000 pages of documents and oral evidence, the Tribunal delivered a unanimous award on 11 May 2017 in favour of DAMEPL.

DAMEPL was awarded: (i) Rs. 2,782.33 crores as termination payment plus interest; (ii) Rs. 147.52 crores for operating expenses and debt service from 7 January to 30 June 2013, plus 11% interest; (iii) Rs. 62.07 crores as refund of encashed bank guarantees plus 11% interest; (iv) Rs. 56.8 lakhs as security deposits plus 11% interest. DMRC was entitled to recover Rs. 46.04 crores as concession fee.

The Tribunal found that 72% of girders were affected by cracks, the cause was uncertain, the depth unreliably determined, and DMRC's inspection was "non-serious." On the CMRS certificate, the Tribunal held that since speed restrictions were imposed, the line's purpose as a high-speed connection was not served, rendering the certificate irrelevant to whether defects were cured.

The Five Levels of Judicial Scrutiny

This case is remarkable for having passed through five distinct levels of judicial scrutiny — a fact the Court itself was keenly aware of:

Level 1: Single Judge, Delhi High Court — Section 34 Application

DMRC challenged the award under Section 34 of the Arbitration Act. The Single Judge dismissed the petition, holding that so long as the award was reasonable and plausible, no interference was warranted even if an alternate view was possible.^[1]

Level 2: Division Bench, Delhi High Court — Section 37 Appeal

The Division Bench partly set aside the award as perverse and patently illegal on three grounds:^[2]

• The termination, effective immediately from the date of the termination notice, was ex facie invalid, with ambiguity on the relevant date of termination and no interpretation of the cure period under Clause 29.5.1(i).
• Speed restrictions were not stated as a reason for termination in either the cure notice or the termination notice, yet the Tribunal relied on them.
• The CMRS sanction under the 2002 Act was vital evidence that the Tribunal had overlooked — its legal effect was binding, and wrongly separating it from the issue of termination validity constituted patent illegality.

Level 3: Two-Judge Bench, Supreme Court — SLP under Article 136

DAMEPL filed a Special Leave Petition. A two-judge bench restored the arbitral award, setting aside the Division Bench's judgment,^[3] holding: (i) construction of contractual provisions was within the exclusive domain of the Tribunal; (ii) factual findings (that defects were not cured within 90 days) could not be interfered with; (iii) the CMRS certificate had no bearing on the validity of termination; and (iv) the Tribunal comprised engineers, and the award could not be scrutinised as if drawn by a legally trained mind.

Level 4: Review Petition — Dismissed

DMRC's review petition was dismissed on 23 November 2021.

Level 5: Curative Petition — Allowed

The present judgment. The three-judge Bench led by the Chief Justice of India allowed the curative petition, set aside the two-judge bench's judgment, and restored the Division Bench's decision.

Issues before the Court

The Court formulated two issues: (i) whether the curative petition was maintainable; and (ii) whether the Court was justified in restoring the arbitral award which had been set aside by the Division Bench on the ground that it suffered from patent illegality.

Analysis and Decision

I. Curative Jurisdiction: The "Grave Miscarriage of Justice" Standard

The Court began by examining the contours of curative jurisdiction under Article 142, as delineated in Rupa Ashok Hurra v. Ashok Hurra^[4]. That Constitution Bench had held that the concern for rendering justice cannot be considered less important than the principle of finality:

"The duty to do justice in these rarest of rare cases shall have to prevail over the policy of certainty of judgment as though it is essentially in public interest that a final judgment of the final court in the country should not be open to challenge, yet there may be circumstances… wherein declining to reconsider the judgment would be oppressive to judicial conscience and would cause perpetuation of irremediable injustice."— Rupa Hurra, para 42

The Court held that the enumeration of grounds in Rupa Hurra was not exhaustive. The overarching principle is that curative jurisdiction may be invoked to (i) prevent abuse of process, or (ii) cure a gross miscarriage of justice — including cases where the Court acts beyond its jurisdiction.

II. Scope of Interference with Arbitral Awards

The Court laid down a structured framework for judicial review of arbitral awards across multiple tiers:

• Section 34: Delineates the grounds for setting aside an award. Under Section 34(2-A) (introduced by the 2015 Amendment), a domestic award may be set aside if vitiated by "patent illegality appearing on the face of the award" — but not merely for erroneous application of law or reappreciation of evidence.
• Section 37: Appellate jurisdiction, which is "akin to" Section 34 and restricted to the same grounds.
• Article 136: Discretionary and exceptional jurisdiction. The Court must interfere "sparingly" and must limit itself to testing whether the Section 37 court exceeded its jurisdiction by failing to apply the correct tests — unlike Sections 34/37, the Court under Article 136 does not re-evaluate the award itself.

Drawing on Associate Builders v. DDA^[5] and Ssangyong Engineering v. NHAI^[6], the Court restated that patent illegality arises where: (i) a finding is based on no evidence; (ii) irrelevant material is considered; or (iii) vital evidence is ignored. An award is perverse where the construction of a contract is one "that no fair-minded or reasonable person would take."

III. The Award Was Patently Illegal: Two Grounds

Ground 1: Unreasonable Interpretation of the Termination Clause

Clause 29.5.1(i) of the Concession Agreement entitled DAMEPL to terminate if DMRC "failed to cure such breach or take effective steps for curing such breach" within the cure period. The clause thus contained two distinct components: (a) curing defects; and (b) taking effective steps to cure.

The Tribunal conflated the two. It found that since defects remained after the cure period, this was indicative of both a failure to cure and a failure to take effective steps. But as the Court pointed out, the existence of uncured defects at the end of the cure period speaks only to component (a). It says nothing about whether effective steps — incremental progress, engagement of consultants, commencement of repairs — were taken during the period.

"The Tribunal did not appreciate the individual import of the two phrases separately from each other. This was not a matter of mere 'alternate interpretation' of the clause, but an unreasonable and uncalled for interpretation of the clause, which frustrated the very provision, and which no reasonable person would have accepted considering the terms of the clause."— Para 51

The Court noted that the parties had deliberately included both phrases. If complete cure within 90 days were the only standard, the words "effective steps" would be rendered otiose. A reasonable interpretation would recognise that incremental progress, even if it does not culminate in complete cure, is an acceptable basis for continuing the agreement.

Ground 2: The Award Overlooked Vital Evidence

The Tribunal had separated the issue of the validity of termination from the relevance of the CMRS certificate — treating the latter as pertaining solely to "whether defects were cured" (which it answered in the negative, citing speed restrictions). This separation was erroneous for two interconnected reasons.

First, the joint application to the CMRS. On 19 November 2012 — during the pendency of the cure period and after the termination notice — both parties jointly applied for reopening of operations. The jointly signed administrative note stated that repairs had been inspected, the integrity of girders was found intact, and train trials "after repairs by DMRC have been completed successfully… including at speed of 120 kmph." This was direct evidence of effective steps taken by DMRC, yet the Tribunal's award contained no explanation for why these steps were not "effective" within the meaning of the clause.

Second, the cure notice itself was premised on safety. DAMEPL's cure notice emphasised that the project was not "safe for operations" and posed a threat to life and property. The CMRS, as the statutory authority under the 2002 Act, was the relevant stakeholder whose satisfaction about safety was necessary for running the metro. By certifying the line as safe to operate (even with conditions), the CMRS was addressing the very concern that DAMEPL had invoked to terminate. The Tribunal's dismissal of this certificate as "irrelevant" to the termination issue was a failure to reconcile the cure notice's safety basis with the statutory certification that the safety concern had been addressed.

The Holding

The Court held that the two-judge bench's judgment in Delhi Airport Metro Express Pvt. Ltd. v. DMRC, (2022) 1 SCC 131, had resulted in a grave miscarriage of justice. The Division Bench of the High Court had correctly applied the test under Section 34 in holding the award suffered from perversity and patent illegality. There was no valid basis for the Supreme Court to have interfered under Article 136.

The curative petition was allowed. The parties were restored to the position they were in on the pronouncement of the Division Bench's judgment. Execution proceedings were to be discontinued, and amounts paid by DMRC (Rs. 2,599.18 crores as of January 2024, with Rs. 5,088 crores outstanding) were to be refunded.

The Caveat

The Court added an important qualification at paragraph 70:

"The exercise of the curative jurisdiction of this Court should not be adopted as a matter of ordinary course. The curative jurisdiction should not be used to open the floodgates and create a fourth or fifth stage of court intervention in an arbitral award, under this Court's review jurisdiction or curative jurisdiction, respectively."— Para 70

Significance and Key Takeaways

Curative jurisdiction in arbitration — exercised but circumscribed. This is one of the rare instances where the Supreme Court exercised curative jurisdiction to set aside its own earlier judgment in a commercial arbitration dispute. The Court was careful to emphasise that this was in "rarest of rare" circumstances and that curative jurisdiction "should not be adopted as a matter of ordinary course." The judgment has attracted both support (for preventing what the Court described as an "undeserved windfall") and criticism (for effectively creating a fifth level of judicial scrutiny over an arbitral award, contrary to the Arbitration Act's pro-finality architecture).

The "effective steps to cure" vs. "cure" distinction. The Court's holding that the Tribunal conflated two distinct contractual concepts — complete cure and effective steps towards cure — is a significant contribution to the interpretation of termination clauses in concession agreements. Parties drafting such clauses must be aware that courts will give independent meaning to each phrase, and that "effective steps" toward remedy may be sufficient to stave off termination even if complete cure has not been achieved within the specified period.

Statutory certificates as vital evidence. The judgment establishes that where a party invokes safety as the basis for termination, a statutory certificate from the competent authority (here, the CMRS under the 2002 Act) attesting to the safety of the infrastructure is vital evidence that cannot be dismissed as "irrelevant" by the Tribunal. Ignoring such evidence renders the award perverse and patently illegal.

Article 136 — a narrow jurisdiction over Section 37 decisions. The Court clarified the hierarchy of judicial review in arbitration matters. Unlike Sections 34 and 37 (which test the award against specified grounds), the Court under Article 136 must limit itself to testing whether the Section 37 court exceeded its jurisdiction. The two-judge bench had erred by effectively substituting its own view for the Division Bench's, rather than testing whether the Division Bench had applied the correct legal standard.

Financial magnitude. The amounts at stake — Rs. 2,599.18 crores already paid, Rs. 5,088 crores outstanding — underscore why this judgment has implications far beyond the immediate parties. It signals to investors, particularly in PPP infrastructure projects, that the Supreme Court's curative power is a live (if exceptional) remedy against what it considers patently illegal awards, even after multiple rounds of judicial affirmation.
