On 13 December 2023, a seven-judge Constitution Bench of the Supreme Court handed down judgment in In re: Interplay Between Arbitration Agreements Under the Arbitration and Conciliation Act 1996 and the Indian Stamp Act 1899, reported as (2024) 6 SCC 1. The decision resolved a vexed jurisprudential question that had divided coordinate benches for a decade: whether an arbitration clause embedded in an unstamped instrument is enforceable, and if so, at what stage of the litigation can the stamping defect be raised.
The Court held that an arbitration agreement contained in an unstamped instrument is not void and is not unenforceable. The defect of stamping is curable. The arbitral tribunal, not the appointing court, is the right forum to address the stamping question. The judgment also recalibrated the broader inquiry the appointing court conducts at the Section 11 stage, narrowing it considerably and reinforcing the negative competence-competence principle that the Court had been building since BALCO.
For practitioners, the judgment has three sets of implications. The first concerns the Section 11 appointing process itself, where the inquiry is now substantially narrower. The second concerns the practical conduct of Section 11 hearings, particularly where the respondent advances stamping or related preliminary objections. The third concerns the strategic timing of disputes, where the predictable shift of inquiry to the arbitral tribunal alters the calculation for both parties.
The Jurisprudential Trajectory
The Indian Supreme Court has moved, over the past two decades, from a position of close supervision of arbitration to one of structured deference. Bharat Aluminium v. Kaiser Aluminium (2012) on foreign-seat arbitrations, the 2015 Amendment Act, TRF Ltd. v. Energo Engineering Projects Ltd. (2017) and Perkins Eastman Architects DPC v. HSCC (India) Ltd. (2019) on arbitrator ineligibility, BGS SGS SOMA JV v. NHPC (2019) on seat jurisdiction, Hindustan Construction Co. Ltd. v. Union of India (2019) on automatic stay, all moved in the same direction. The Court was building, judgment by judgment, a coherent doctrine that the arbitration agreement is sui generis, that it survives challenges to the underlying contract, and that the court’s role is to vindicate the agreement, not to second-guess the choice to arbitrate.
The stamping question, however, was the stubborn outlier. In SMS Tea Estates (P) Ltd. v. Chandmari Tea Co. (P) Ltd. (2011) the Court had held that an unstamped instrument carrying an arbitration clause was not admissible in evidence and the court could not act on the arbitration clause. Garware Wall Ropes Ltd. v. Coastal Marine Constructions and Engineering Ltd. (2019) extended that position. N.N. Global Mercantile (P) Ltd. v. Indo Unique Flame Ltd. (2021) referred the question to a Constitution Bench, which by 3:2 majority confirmed the SMS Tea Estates position in 2023. The result was a curious doctrinal asymmetry: every other defence to the arbitration clause was for the arbitral tribunal, but stamping was uniquely the court’s job at the appointment stage.
The seven-judge bench in In re Interplay resolved the asymmetry by holding, decisively, that stamping is not for the appointing court either. It is for the tribunal.
What the Section 11 Court Now Examines
The narrowing of the Section 11 inquiry can be stated in three propositions:
One. The court examines whether an arbitration agreement, as defined in Section 7 of the 1996 Act, exists. The standard is prima facie existence, not balance of probabilities. If a writing carries an arbitration clause and a party has signed or otherwise assented to it, the existence question is answered.
Two. The court examines whether the agreement is prima facie not invalid on the face of the record. This is a narrow inquiry. Invalidity that requires the court to weigh evidence is not invalidity at the prima facie stage.
Three. The court examines whether there is a serious dispute on existence or validity. If there is, the answer is to refer the question to the tribunal, not to resolve it.
This standard, when applied, displaces a substantial body of objections that respondents had previously been able to advance at the Section 11 stage. Stamping is now firmly out. Allegations of fraud in the formation of the underlying contract are out. Disputes over whether an oral variation modified the arbitration agreement are out. The argument that the dispute is non-arbitrable in part is, after Vidya Drolia, also substantially for the tribunal.
The Bridge to SBI General Insurance
In re Interplay set the constitutional framework. SBI General Insurance Co. Ltd. v. Krish Spg., decided in 2024 and reported as (2024) 12 SCC 1, applied it to a specific recurring fact pattern. In Krish Spg., the insured had executed a discharge voucher purportedly in full and final settlement. The insurer argued that the discharge constituted accord and satisfaction, extinguishing the arbitration clause along with the substantive contract. The Court held that the arbitration agreement is separable from the underlying contract. Even if the substantive obligations are settled, the arbitration agreement may survive. Where the discharge is itself contested, on grounds of duress for example, the question of whether the discharge was valid is for the arbitral tribunal, not the appointing court.
Krish Spg. is now the operational test for any Section 11 application where the respondent raises an accord-and-satisfaction defence. The Court will not undertake a merits inquiry. It will assess whether the arbitration agreement exists and is prima facie valid, and refer the substantive question to the tribunal.
Strategic Implications for Counsel
For claimants invoking Section 11, the strategic posture is now straightforward. Establish prima facie existence of the arbitration agreement, plead default or breach in the briefest terms necessary, and resist the respondent’s attempt to drag the court into a merits inquiry. Cite In re Interplay and Krish Spg. for the proposition that the inquiry is narrow.
For respondents, the strategic posture is more difficult than it was before In re Interplay. The historic stamping defence is gone. Preliminary objections will succeed only where the agreement does not exist or is patently void. Substantive defences should be deployed before the tribunal, not the court, and the respondent should be prepared to spend time and money on the tribunal hearing. The cost calculus has shifted.
For both sides, the timing of disputes matters. The narrower the Section 11 inquiry, the faster the appointment, and the faster the substantive merits move to the tribunal. The 2015 Amendment had already compressed Section 11 to a target of six months. The narrowed inquiry reinforces that timeline. Cases that previously sat at the Section 11 stage for a year or longer should now reach tribunal stage within the statutory target.
Open Questions
Three questions remain open after In re Interplay and Krish Spg.
First, the relationship between the narrowed Section 11 inquiry and the conditions in Section 8 (where the court refers a pending suit to arbitration). Section 8 carries its own statutory language. Whether the in-court reference under Section 8 carries the same narrowed inquiry as the appointment under Section 11 has not been definitively addressed by the seven-judge bench. The trajectory suggests it will, but the question awaits direct adjudication.
Second, the treatment of arbitration agreements where the existence of the agreement itself is the disputed question. If a party denies signing the contract, is that for the court or the tribunal? In re Interplay leaves the question to be addressed on a case-specific basis.
Third, the calibration of the prima facie standard in the context of group-of-companies doctrine. Cox & Kings Ltd. v. SAP India (P) Ltd., decided in 2023 by a five-judge bench, addressed the consent question in group-of-companies cases. Whether the appointing court, at the Section 11 stage, undertakes a merits inquiry into the alter ego or piercing-the-veil arguments is a fact-specific question. Practitioners should expect a series of NCLAT and High Court decisions over the next 18 months that work through the operational detail.
Conclusion
The trajectory from BALCO to In re Interplay to SBI General Insurance v. Krish Spg. is the most significant institutional shift in Indian arbitration since the 1996 Act itself. The Section 11 appointing process is, after these three decisions, a procedural gateway rather than a merits review. The arbitral tribunal is, in practice, the forum of first substantive inquiry. For commercial parties, the practical consequence is that arbitration in India is faster, more predictable, and more clearly bounded than it has been at any time since the Code came into force.
