In Re: Interplay Between Arbitration Agreements and the Indian Stamp Act, 2023 INSC 1066, decided by a 7-Judge Constitution Bench of the Supreme Court of India on 13 December 2023, held that an unstamped or insufficiently stamped arbitration agreement is enforceable and non-stamping is a curable defect, not a voidness. The ruling overruled NN Global (5-Judge), SMS Tea Estates and Garware Wall Ropes, and is central to CLAT current affairs and Judiciary Mains arbitration papers.
Key Takeaways
- An unstamped arbitration agreement is not void; non-stamping is a curable defect under the Stamp Act.
- Section 11(6A) confines referral courts to examining only the existence of an arbitration agreement.
- Stamping and penalty issues fall to the arbitral tribunal, not the referral court.

How did the case reach the Supreme Court?
Answer: The dispute began in Nagpur Commercial Court over a sub-contract between Indo Unique Flame Ltd. and NN Global Mercantile Pvt. Ltd. containing an unstamped arbitration clause. The Commercial Court rejected the Section 8 reference; the Bombay High Court reversed. The matter reached a 3-Judge Bench, then a 5-Judge Bench (which held unstamped arbitration agreements void), and finally came before the 7-Judge Bench on a curative petition.
| Stage | Forum | Outcome |
|---|---|---|
| First instance | Nagpur Commercial Court | Section 8 application rejected |
| First appeal | Bombay High Court | Reversed; arbitration held applicable |
| Reference | 3-Judge Bench, Supreme Court | Referred to larger Bench |
| Full Bench | 5-Judge Bench, Supreme Court (2023) | Majority held unstamped agreement unenforceable |
| Curative petition | 7-Judge Bench, Supreme Court | Overruled 5-Judge NN Global; petition allowed |
What are the facts in brief?
Answer: Indo Unique Flame Ltd. awarded a sub-contract to NN Global Mercantile Pvt. Ltd., which contained an arbitration clause (Clause 10) and a bank-guarantee clause (Clause 9). When Karnataka Power Corporation invoked the principal bank guarantee, Indo Unique invoked NN Global's counter-guarantee, triggering a commercial dispute.
NN Global refused payment and filed a civil suit. Indo Unique responded with a Section 8 application seeking reference to arbitration. The sub-contract had not been stamped as required under the Indian Stamp Act, 1899. The central question was whether this non-stamping rendered the arbitration clause itself void or whether it was merely a curable fiscal irregularity.
What were the issues before the court?
Answer: The Supreme Court framed four issues in In Re: Interplay, centred on the relationship between the Arbitration Act and the Stamp Act.
- Issue 1: Whether an arbitration agreement contained in an unstamped or insufficiently stamped instrument is void ab initio?
- Issue 2: Whether Section 11(6A) of the Arbitration and Conciliation Act, 1996 permits the referral court to examine stamping compliance?
- Issue 3: Whether the doctrine of separability under Section 16 of the Arbitration Act protects the arbitration clause from stamping defects in the main contract?
- Issue 4: Whether the earlier decisions in SMS Tea Estates, Garware Wall Ropes and the 5-Judge NN Global require reconsideration?
What did the court hold?
Answer: In In Re: Interplay Between Arbitration Agreements and the Indian Stamp Act, 2023 INSC 1066, the 7-Judge Constitution Bench held, allowing the curative petition, that an unstamped or insufficiently stamped arbitration agreement is enforceable and must be referred to arbitration. The Bench overruled the 5-Judge majority in NN Global along with SMS Tea Estates and Garware Wall Ropes.
- Holding 1: An unstamped arbitration agreement is not void; non-stamping is a curable defect under Section 35 of the Indian Stamp Act, 1899.
- Holding 2: Section 11(6A) of the Arbitration Act limits the referral court's examination to the existence of an arbitration agreement — stamping is not within that inquiry.
- Holding 3: The arbitration clause is severable under Section 16; its validity is independent of the stamping status of the main contract.
- Holding 4: Stamping and penalty issues must be decided by the arbitral tribunal, not by the referral court at the Section 8 / Section 11 stage.
- Holding 5: NN Global (5-Judge), SMS Tea Estates and Garware Wall Ropes are overruled on the stamping point.
Why is In Re: Interplay a landmark?
Answer: The 7-Judge ruling is a landmark because it restores India's pro-arbitration regime by removing stamping as a judicial chokepoint at the referral stage. By overruling the 5-Judge NN Global, it aligns Indian arbitration jurisprudence with Section 11(6A)'s legislative intent and with international practice (UNCITRAL Model Law). The decision also clarifies the constitutional status of the doctrine of separability and minimises judicial intervention, making India a more attractive seat for commercial arbitration.

Frequently asked questions
Does non-stamping make an arbitration agreement void after this judgment?
No. After In Re: Interplay (2023 INSC 1066), non-stamping or insufficient stamping of the substrate instrument does not render the arbitration agreement void. It is a curable fiscal defect addressable on payment of duty and penalty under Section 35 of the Indian Stamp Act, 1899. The arbitration clause remains enforceable and parties must be referred to arbitration under Section 8 of the Arbitration and Conciliation Act, 1996.
What does 'existence' mean under Section 11(6A)?
'Existence' under Section 11(6A) refers only to whether a prima facie arbitration agreement between the parties can be identified. The 7-Judge Bench held that this inquiry excludes collateral issues like stamping, validity under other statutes, or enforceability. The referral court's role is strictly limited; the arbitral tribunal decides all substantive questions.
Who decides stamping disputes after this ruling?
The arbitral tribunal. The 7-Judge Bench held that stamping and penalty disputes are to be addressed by the arbitrator under Section 28 of the Arbitration and Conciliation Act, 1996 read with the Indian Stamp Act, 1899. The referral court cannot use stamping as a ground to refuse reference under Sections 8 or 11.
Is the doctrine of separability constitutionally grounded?
The doctrine of separability under Section 16 of the Arbitration Act treats the arbitration clause as an independent agreement, unaffected by defects in the main contract. The 7-Judge Bench reinforced this, holding that separability is a foundational pillar of Indian arbitration law and protects the arbitration clause from stamping irregularities in the parent contract.
Does this judgment apply retrospectively to pending Section 11 petitions?
Yes. The 7-Judge Bench decision is declaratory of the correct legal position and therefore applies to all pending and future Section 8 / Section 11 petitions. Courts that previously refused reference on the strength of NN Global must now reconsider in line with In Re: Interplay.
