A recent Supreme Court ruling has revived a basic question of arbitration law: can parties arbitrate a dispute that is already before a civil court? This explainer sets out what section 21 and section 47 of the Arbitration Act, 1940 require, and why an award obtained without the court’s leave cannot defeat a pending suit.
Parties cannot quietly take a dispute that is already before a civil court off to private arbitration and then use the resulting award to shut the suit down. Under the Arbitration Act, 1940, an in-suit dispute can go to arbitration only through an order of the court under section 21, and an award obtained without that leave cannot defeat the suit. That principle was applied afresh by the Supreme Court in late May 2026.
The occasion for revisiting it was the Court’s decision in Ashok v. Padam Chand, where a Bench of Justice J.K. Maheshwari and Justice Atul S. Chandurkar set aside concurrent findings that had non-suited a Gwalior property owner on the strength of a 1983 arbitral award passed while his possession suit was pending.
The facts, the arguments and the ruling are covered in our full report on that judgment, linked here. This piece steps back from the case to explain the law it turns on, since the provisions involved, a repealed 1940 statute, trip up students and litigants alike.

A short caveat before the law: the Arbitration Act, 1940 has been replaced by the Arbitration and Conciliation Act, 1996. It is no longer the law for new arbitrations. It still governs old references that began under it, which is why a 2026 judgment is still parsing a 1940 statute. The explanation below is grounded in the statutory text and the way the Court read it.
What is the Arbitration Act, 1940?
The 1940 Arbitration Act governed domestic arbitration in India before 1996 Arbitration Act came into force. Its purpose was to consolidate arbitration law and to keep arbitration disputes within the structure the Act prescribed, rather than letting parties improvise around the courts. It was repealed and replaced by the 1996 Act, which is the regime in force now. The practical reason the old Act still surfaces is that arbitrations and references commenced under it continue to be decided under it, so its provisions remain live law for that shrinking pool of legacy disputes.
What are the three kinds of arbitration under the 1940 Act?
The Act recognised three separate situations, and treated them as mutually exclusive compartments.
The first is arbitration without any court involvement, where parties with an arbitration agreement simply arbitrate and bring the award to court only at the enforcement stage.
The second is arbitration with court intervention where no suit is pending, where a party can approach the court to order a reference even though no suit has been filed.
The third is arbitration in a pending suit, governed by Chapter IV of the Act, which applies once litigation over the dispute is already on foot. The Supreme Court’s reasoning rests on the idea that these are distinct routes: once a suit is pending, the third compartment is the only one available, and its gateway is section 21.
What does Section 21 of the Arbitration Act, 1940 say?
Section 21 provides that where, in any suit, all the parties interested agree that a matter in difference between them in the suit should be referred to arbitration, they may, at any time before judgment is pronounced, apply in writing to the court for an order of reference. The mechanism is the whole point. A dispute already before a civil court cannot be carved out and arbitrated privately on the parties’ own initiative. The parties must return to the court and obtain its order referring the matter to arbitration. That order, the court’s “leave”, is what gives an in-suit arbitration its legal footing. Without it, the arbitration is not a valid in-suit reference at all.
Why can an award without the court’s leave not defeat a pending suit?
Because an award produced outside the only permitted route is not an award made in compliance with the Act, so far as the pending suit is concerned. If a suit on the dispute is already before the court and the parties arbitrate anyway without a section 21 order, the award they obtain cannot be treated as having settled or extinguished the suit. The suit survives, and must be decided on its own merits. This is exactly what the Court held in Ashok v. Padam Chand: “an award passed without the trial court’s leave, while a suit on the same subject matter is pending, cannot defeat that suit.”
Does it matter whether a party knew the suit was pending?
No. The trigger for section 21 is the institution or pendency of the suit itself, an objective fact about the state of the litigation, not the subjective awareness of any party. A party cannot rescue an otherwise non-compliant award by pleading that it did not know a suit was pending. The statutory scheme does not make knowledge the test; pendency is the test.
What is the proviso to section 47, and what does “post-award consent” mean?
Section 47 says the 1940 Arbitration Act applies to all arbitrations and all proceedings under it. Its proviso supplies the only narrow way an award obtained outside the proper route can still have effect in a pending suit: such an award, “otherwise obtained”, may be taken into consideration as a compromise or adjustment of the suit, but only with the consent of all the parties interested.
The nuance that decides most of these cases is what the consent must be directed at. It is not consent to arbitrate, given before or during the arbitration. It is consent, given after the award is made, to treat that award as a compromise of the pending suit. A party who fought the award throughout has plainly not given it. That distinction, drawn from a line of authority including Naraindas v. Vallabhdas, is why an unwilling litigant cannot be bound by an irregular award dressed up as a settlement.
How does the 1996 Act handle this differently?
The 1940 Act’s elaborate machinery of court-supervised references, including the “arbitration in suits” route under section 21, was a feature of its court-centric design. The Arbitration and Conciliation Act, 1996 took a different philosophy, minimising court intervention and building arbitration around the parties’ agreement and the tribunal’s own authority.
The 1996 Act has its own provision numbered section 21, but it deals with something unrelated, the date on which arbitral proceedings are deemed to commence, not references in pending suits.
Section 21 of the 1996 Arbitration Act, “Commencement of arbitral proceedings.—Unless otherwise agreed by the parties, the arbitral proceedings in respect of a particular dispute commence on the date on which a request for that dispute to
be referred to arbitration is received by the respondent.”
The pending-suit leave requirement discussed here belongs to the 1940 Act.
