Separability of arbitration clauses, arbitrability of bank guarantee fraud, and limits on writ review where statutory appeal exists.

An arbitration clause embedded in an unstamped work order is treated as a separate and independent agreement under the doctrine of separability, so non-payment of stamp duty on the main instrument does not by itself extinguish the arbitration agreement; the defect is curable and the instrument must be impounded and stamped before the substantive contract is acted upon. Fraud allegations concerning invocation of a bank guarantee, where they arise from the parties' contractual relationship, remain arbitrable unless they amount to serious fraud of a public law character or fraud directed at the arbitration agreement itself. A writ petition challenging refusal to refer disputes to arbitration is not ordinarily maintainable where the Arbitration and Conciliation Act, read with the Commercial Courts Act, provides an efficacious statutory appeal.

Issues: (i) Whether an arbitration agreement embedded in an unstamped work order can be enforced and acted upon pending compliance with stamp duty requirements; (ii) whether fraudulent invocation of a bank guarantee is an arbitrable dispute; (iii) whether a writ petition under Articles 226 and 227 of the Constitution was maintainable to challenge the order refusing reference to arbitration under Section 8 of the Arbitration and Conciliation Act, 1996.

Issue (i): Whether an arbitration agreement embedded in an unstamped work order can be enforced and acted upon pending compliance with stamp duty requirements.

Analysis: The arbitration agreement is a separate and independent agreement from the substantive contract. The doctrine of separability protects the arbitration clause from the invalidity or inadmissibility of the main contract. Non-payment of stamp duty on the substantive instrument creates a curable defect in relation to the contract, but does not destroy the arbitration agreement itself, which is not chargeable to stamp duty. The contrary view in earlier authorities on unstamped contracts was held to be incorrect on this point.

Conclusion: The arbitration agreement remains enforceable notwithstanding that the work order is unstamped, subject to the statutory requirement that the instrument be impounded and stamp duty be paid before the substantive contract can be acted upon.

Issue (ii): Whether fraudulent invocation of a bank guarantee is an arbitrable dispute.

Analysis: Civil fraud, fraud in the performance of contractual obligations, and disputes turning on the inter se rights of the parties are arbitrable. Only disputes involving serious fraud of a public law character, fraud directed at the arbitration agreement itself, or allegations that vitiate the agreement to arbitrate may fall outside arbitration. A mere allegation that invocation of a bank guarantee was fraudulent, arising from the contractual relationship between the parties, does not by itself exclude arbitral adjudication.

Conclusion: The dispute relating to fraudulent invocation of the bank guarantee is arbitrable.

Issue (iii): Whether a writ petition under Articles 226 and 227 of the Constitution was maintainable to challenge the order refusing reference to arbitration under Section 8 of the Arbitration and Conciliation Act, 1996.

Analysis: An order refusing reference to arbitration is appealable under the statutory scheme. Where an efficacious statutory appeal lies, recourse to writ jurisdiction is not maintainable. The existence of a special appellate remedy under the Arbitration and Conciliation Act, 1996, read with the Commercial Courts Act, 2015, barred the writ challenge.

Conclusion: The writ petition was not maintainable.

Final Conclusion: The High Court order was set aside, the dispute was directed to proceed in accordance with the arbitration framework after compliance with stamp duty requirements, and the challenge to the bank-guarantee dispute was left open to interim relief under the arbitration law. The issue on the effect of stamp duty on the arbitration agreement was referred for authoritative determination by a Constitution Bench.

Ratio Decidendi: An arbitration agreement is severable from the substantive contract and may be enforced even if the underlying instrument is unstamped, while civil fraud disputes arising out of the parties' contractual relationship remain arbitrable and writ jurisdiction will not ordinarily lie where a statutory appeal is available.
