Unstamped contract = no arbitration clause, says SC majority
A 5-judge bench holds that an unstamped agreement is void and cannot contain an arbitration clause, even if both parties signed. The minority says stamp duty is a curable defect.

A 5-judge bench holds that an unstamped agreement is void and cannot contain an arbitration clause, even if both parties signed. The minority says stamp duty is a curable defect.
They signed a contract with an arbitration clause. But the stamp paper was missing. The Supreme Court just said: that arbitration clause doesn't exist.
The dispute was ordinary enough. A sub-contractor, N.N. Global, had a work order from Indo Unique Flame Ltd. The work order contained an arbitration clause — a promise that if something went wrong, they'd settle it privately, outside court. When a bank guarantee dispute erupted, N.N. Global filed a suit. The main contractor responded by asking the court to send the matter to arbitration under Section 8 of the Arbitration and Conciliation Act (the provision that lets a court refer parties to arbitration if a valid arbitration agreement exists).
But there was a catch. The work order — the very document containing the arbitration clause — was unstamped. No stamp duty had been paid on it. In the courtroom, the physical file felt thin, almost incomplete — a stack of papers that lacked the official seal that gives a commercial document its legal weight.
The question that reached a 5-judge Constitution Bench of the Supreme Court was deceptively simple: Can an arbitration clause exist inside a contract that has never been stamped?
When the Commercial Court said no
The Commercial Court rejected the main contractor's Section 8 application. Its reasoning: an unstamped instrument cannot be acted upon, and therefore the arbitration clause within it was unenforceable. The High Court disagreed. It allowed the writ petition, holding that the arbitration agreement could be separated from the unstamped contract and enforced independently.
That split — between treating the arbitration clause as inseparable from the unstamped document versus severable from it — is what ultimately landed before the Supreme Court. A 3-judge bench referred the matter to a Constitution Bench in January 2021, noting that earlier precedents had created confusion.
The majority's chain
Justice K.M. Joseph led the majority, joined by Justices Ajay Rastogi, Aniruddha Bose, and C.T. Ravikumar. The bench's silence was heavy as the judgment was read out, the only sound the rustle of paper as each page turned. They held that Section 35 of the Indian Stamp Act, 1899 — which bars unstamped instruments from being admitted in evidence or acted upon — is mandatory. An unstamped agreement, they said, is not a "contract" enforceable in law under Section 2(h) of the Indian Contract Act, 1872 (the definition of a contract as an agreement enforceable by law). It falls instead under Section 2(g) — a void agreement (an agreement not enforceable by law).
If the contract itself is void for lack of stamping, the majority reasoned, the arbitration clause inside it is also non-existent. It cannot be enforced until the instrument is validated by paying the requisite stamp duty and penalty under the Stamp Act. The majority's core holding was direct: "an instrument exigible to stamp duty which is unstamped or insufficiently stamped cannot be said to be a contract enforceable in law within S.2(h) of the Contract Act and is unenforceable under S.2(g), rendering the arbitration agreement contained therein non-existent until validated under the Stamp Act."
The minority's dissent
Justice Hrishikesh Roy disagreed sharply, with a lone voice in the 3:2 split. Non-stamping, he said, is a curable defect — a procedural gap, not a death sentence for the arbitration clause. The arbitration agreement, he argued, is separate from the underlying contract. The Stamp Act's bar on acting upon an unstamped instrument should not stall arbitration. The deficiency can be cured later by paying the stamp duty and penalty. The minority held that stamping deficiency is curable and should not impede arbitral reference — a view that would have kept the arbitration alive while the stamp issue was resolved separately.
But the minority's view did not carry the day. The majority's reasoning was anchored in the mandatory language of the Stamp Act, which they held overrode the pro-arbitration bias of the Arbitration Act at the threshold stage.
What the court must do now
The majority's logic rests on a chain of statutory links. When a party asks the court to appoint an arbitrator under Section 11 of the Arbitration Act, the court must examine whether the instrument is stamped. If it is unstamped or insufficiently stamped, the court must impound it (seize it for stamp duty assessment) at that stage itself. The principle of minimal judicial interference under Section 5 of the Arbitration Act cannot bypass this mandatory requirement.
This is not merely a procedural formality. The court at the Section 11 stage is bound to examine stamping and impound if necessary — a duty that cannot be delegated to the arbitral tribunal. The court also addressed what happens when a certified copy of the unstamped instrument is produced at the Section 11 stage. The majority held that such a copy can be acted upon only if it clearly indicates the stamp duty paid. If it does not, the court should not rely on it. In practice, this means a lawyer handing over a certified copy must ensure the stamp duty notation is visible on its face — otherwise, the court will treat it as if the original were missing.
The practical consequence is significant. A party seeking arbitration must now ensure that the underlying contract — the one containing the arbitration clause — is properly stamped before approaching the court. If it is not, the court will not refer the matter to arbitration. The arbitration clause is treated as non-existent until the instrument is validated.
The precedents that led here
The majority relied on a line of cases stretching back over a decade. In SMS Tea Estates (P) Ltd. v. Chandmari Tea Co. (P) Ltd. (2011), the court had first flagged the issue of stamping at the referral stage. Garware Wall Ropes Ltd. v. Coastal Marine Constructions & Engg. Ltd. (2019) reinforced that position, holding that an unstamped arbitration agreement could not be acted upon. The majority in the present case reaffirmed both these decisions.
The court also considered Vidya Drolia v. Durga Trading Corporation (2021), which had clarified the scope of judicial review at the Section 11 stage, and SBP & Co. v. Patel Engineering Ltd. (2005), which had established that the Chief Justice or his designate exercises a judicial function when appointing arbitrators. The earlier 3-judge bench decision in N.N. Global itself — which had taken a different view — was specifically overruled on this point.
Other cases cited included Duro Felguera, S.A. v. Gangavaram Port Limited (2017), Mayavati Trading Pvt Ltd v. Pradyuat Deb Burman (2019), Hindustan Steel Ltd. v. Dilip Construction Company (1969), and Great Offshore Ltd. v. Iranian Offshore Engg. & Construction Co. (2008) — each contributing to the evolving jurisprudence on the intersection of the Stamp Act and the Arbitration Act.
The procedural journey
The case, M/s. N.N. Global Mercantile Private Limited v. M/s. Indo Unique Flame Ltd. & Ors., had a long path through the courts. It began in the Commercial Court, which rejected the Section 8 application. The High Court, on a writ petition, reversed that decision. A 3-judge bench of the Supreme Court, on 11 January 2021, referred the matter to a Constitution Bench, noting that the law was unsettled. Finally, on 25 April 2023, the Constitution Bench delivered its verdict — a 3:2 majority that settled the law in favour of strict compliance with the Stamp Act.
For practitioners: the bright line
For lawyers and parties drafting commercial contracts, the message is clear: stamp duty is not a formality. It is a precondition to enforceability — including enforceability of the arbitration clause itself. A contract signed by both parties, with a clear arbitration clause, is worthless for arbitration purposes if the stamp paper is missing or insufficient.
The judgment also clarifies the interplay between Section 16 of the Arbitration Act (the kompetenz-kompetenz principle, which allows the arbitral tribunal to rule on its own jurisdiction) and the Stamp Act. The majority held that the tribunal's power to decide its own jurisdiction cannot be invoked when the arbitration agreement itself is non-existent for want of stamping — the jurisdictional question must be resolved by the court at the referral stage.
THE PLAY: Before filing a Section 11 application to appoint an arbitrator, verify that the underlying contract is duly stamped — if it is not, pay the stamp duty and penalty first, or the court will treat the arbitration clause as non-existent.
The court ended where it began: with a contract that could not be acted upon, and an arbitration clause that, for now, was nothing but ink on unstamped paper. The smell of old paper and the weight of the file in the courtroom told the story — a document that should have borne the mark of the state, but did not.
