The Supreme Court has clarified that a non-signatory collaborator, bound by a Deed of Joint Undertaking (DJU) integral to a contract, is a veritable party to the arbitration agreement and may invoke arbitration despite not being a direct signatory. This ruling reinforces the doctrine of substantive arbitrability beyond mere contractual signature, with significant implications for consortium bids and infrastructure contracts.
Background & Facts
The Dispute
The dispute arose from a contract awarded by Bhartiya Rail Bijlee Company Limited (the Employer) to a contractor for the installation of a Coal Handling Plant at the Nabinagar Thermal Power Project. The Employer’s bid document required bidders to demonstrate experience in designing and commissioning integrated bulk material handling plants with a capacity of 1000 Metric Tonnes per hour or above for coal/minerals for at least one year. The 2nd respondent (Contractor) lacked this experience and therefore collaborated with Elecon Engineering Company Limited (the Appellant/Collaborator), whose technical expertise satisfied the eligibility criteria.
Key Facts
- The bid document mandated submission of a Deed of Joint Undertaking (DJU) in NTPC format, executed jointly by the Contractor and the Collaborator, in favor of the Employer.
- The DJU was executed on 22.02.2010 and contained joint and several liability clauses for performance of the contract.
- The contract between the Employer and the Contractor contained a valid arbitration clause.
- The Collaborator supplied critical equipment and design inputs essential to the project’s technical compliance.
- On 16.01.2020, the Contractor was ordered into liquidation.
- Following the Contractor’s default, the Employer issued multiple communications (dated 08.10.2021 and earlier) directing the Collaborator to fulfill contractual obligations under the DJU.
- The Employer encashed the bank guarantee submitted by the Collaborator, citing default.
- A tripartite agreement dated 05.04.2016 was executed between the Employer, Contractor, and Collaborator, authorizing direct payments to the Collaborator for supplies rendered and to be rendered.
- On 02.07.2022, the Collaborator issued a notice under Section 21 of the Arbitration and Conciliation Act, 1996, seeking arbitration for unpaid dues and wrongful encashment of guarantee.
- The Employer responded on 29.07.2022, denying arbitration on grounds of no privity of contract.

Relief Sought
The Appellant sought: (1) setting aside the High Court’s order dismissing the Section 11(6) petition; (2) appointment of an arbitrator to adjudicate disputes relating to unpaid dues, wrongful encashment of bank guarantee, and breach of DJU obligations; and (3) direction for the arbitrator to determine liability under the contract and DJU.
The Legal Issue
The central question was whether a non-signatory collaborator, bound by a Deed of Joint Undertaking that forms an inextricable part of a contract containing an arbitration clause, can invoke arbitration against the employer despite not being a direct signatory to the main contract.
Arguments Presented
For the Appellant
Sri Sridhar Potaraju argued that the DJU was not ancillary but essential to the contract’s formation, as the Contractor could not have bid without the Collaborator’s technical credentials. The DJU created joint and several liability, making the Collaborator a substantive party to the contractual obligations. The tripartite agreement of 05.04.2016 further affirmed the Collaborator’s role and payment rights, reinforcing its status as a veritable party. The reference to arbitration in the Section 21 notice was not a request for consent but an invocation of an existing clause. Reliance was placed on S.B.S. Rajan v. M/s. S. S. Rajan & Co. and Vidya Drolia v. Durga Trading Corporation to establish that substance over form governs arbitrability.
For the Respondent
Sri Aman Lekhi contended that the Collaborator was never a party to the main contract and had no direct arbitration clause with the Employer. The Section 21 notice explicitly sought consent to arbitrate, indicating the Collaborator’s own understanding that no arbitration mechanism existed between it and the Employer. The tripartite agreement was merely a payment mechanism and did not create new obligations or incorporate the arbitration clause. Absent privity of contract, the Collaborator had no standing to invoke arbitration.
The Court's Analysis
The Court rejected the narrow view of privity and emphasized the functional reality of the contractual relationship. It held that the DJU was not a mere ancillary document but a mandatory condition precedent to bid eligibility, making the Collaborator an indispensable party to the contract’s formation and performance.
"The contract by itself necessitated the execution of joint undertaking by the Contractor and the Collaborator who had the ‘joint and several’ liability for the due completion of the contract. The arbitration clause applied both to the Collaborator and the Contractor in so far as the disputes with the Employer and between themselves the agreement of collaboration provided a like clause for dispute resolution."
The Court observed that the tripartite agreement did not replace or extinguish the original contract but merely operationalized payment mechanisms in light of the Contractor’s insolvency. The Employer’s repeated communications invoking the DJU and demanding performance confirmed its recognition of the Collaborator’s contractual status.
The Court distinguished between mere association and substantive integration into the contractual framework. It held that where a non-signatory’s participation is indispensable to the contract’s validity and performance, and where the non-signatory assumes joint liability under a document integral to the contract, the non-signatory becomes a veritable party to the arbitration agreement.
The Court further clarified that the Collaborator’s reference to arbitration in the Section 21 notice was not a request for consent but an invocation of an existing right under the contract, which the Employer had itself acknowledged through its conduct.
The Verdict
The appeal was allowed. The Supreme Court set aside the High Court’s order dated [unspecified] dismissing the Section 11(6) petition. The Court appointed Justice (Retd.) Chakradhari Sharan Singh as the sole arbitrator to adjudicate all disputes between the parties. The arbitrator must submit his award within 15 days of receiving a copy of this judgment and shall be paid in accordance with the Fourth Schedule to the Arbitration and Conciliation Act, 1996. All contentions remain open for presentation before the arbitrator.
What This Means For Similar Cases
Non-Signatories Can Be Bound by Arbitration Clauses Through Functional Integration
- Practitioners must assess whether a non-signatory’s role is indispensable to contract formation or performance, not merely whether they signed the main agreement.
- DJUs, joint liability clauses, and mandatory consortium requirements can create arbitrability even without direct signature.
- Conduct of parties post-default (e.g., invoking obligations, making payments, encashing guarantees) can establish implied consent to arbitration.
Tripartite Agreements Do Not Erase Original Arbitration Rights
- A tripartite agreement that modifies payment terms or allocates responsibilities does not extinguish pre-existing arbitration rights unless explicitly stated.
- Courts will examine the substance of the relationship, not just the form of documentation.
- Where a collaborator is treated as a direct obligor by the employer, arbitration rights are preserved.
Procedural Notice Must Be Interpreted Contextually
- A Section 21 notice seeking "consent" to arbitrate does not automatically negate the existence of an arbitration clause if the context shows the party was invoking an existing right.
- Courts will look at the entire contractual and factual matrix to determine whether arbitration was sought as a right or as a new request.
Practical Takeaways for Infrastructure Contracts
- Drafters of bid documents should explicitly state whether collaborators are bound by arbitration clauses.
- Employers must be cautious in invoking obligations against collaborators under DJUs - doing so may inadvertently create arbitrability.
- Collaborators should retain copies of all bid documents, DJUs, and post-default communications as evidence of their veritable party status.
