Non-Signatories and the Group of Companies Doctrine

An arbitration agreement binds those who agreed to it. The difficulty is that modern commercial transactions are rarely contained in a single contract signed by everyone concerned: a parent negotiates and a subsidiary signs, a group of interlinked agreements implements one commercial arrangement, or a guarantor performs the contract without executing the clause. Indian law has developed two routes to bring such a person within the reference. The first is the statutory expression claiming through or under a party. The second is the group of companies doctrine, which a Constitution Bench upheld and restated in Cox and Kings Ltd. v. SAP India (P) Ltd., (2024) 4 SCC 1.

1. The Starting Point: Consent

Section 2(1)(h) defines a party as a party to an arbitration agreement, and Section 7 requires the agreement to be in writing. Read narrowly, the two provisions would confine arbitration to signatories. The Constitution Bench rejected that reading. The requirement of writing goes to the form in which the agreement must be recorded; it does not dictate who has consented to it. Consent may be shown by conduct as well as by signature, and a person who negotiated, performed and took the benefit of a contract may be a party to its arbitration clause although his name does not appear at the foot of the document.

2. Claiming Through or Under a Party

Sections 8 and 45 permit an application for reference to be made by a party or by any person claiming through or under him. The expression covers persons who derive their right from a party rather than independently of him: assignees, successors in interest, legal representatives of a deceased party under Section 40, a receiver under Section 41, and an insurer suing by subrogation. The test is derivative title. A person asserting an independent right of his own does not claim through or under a party, however closely his claim is connected with the contract.

📖 Chloro Controls India (P) Ltd. v. Severn Trent Water Purification Inc., (2013) 1 SCC 641

Held: In an appropriate case, and particularly where the transaction is a composite one implemented through several interlinked agreements, a non-signatory may be referred to arbitration under Section 45 as a person claiming through or under a party. The Court identified circumstances in which this may be done, including a direct relationship with the signatory, a direct commonality of the subject matter, and an agreement of a composite nature where performance is not feasible without the participation of the non-signatory.

Significance: The decision introduced the composite transaction analysis into Indian law and is the source of the group of companies doctrine as it was applied before 2023.

The reasoning in Chloro Controls arose under Section 45, which is in Part II, and the words claiming through or under were carried into Section 8 by the amendment of 2015. The doctrine was then applied to domestic arbitration, including in Ameet Lalchand Shah v. Rishabh Enterprises, (2018) 15 SCC 678, where four interconnected agreements for a single solar power project were treated as one transaction so that all the parties could be referred.

3. The Group of Companies Doctrine Restated

📖 Cox and Kings Ltd. v. SAP India (P) Ltd., (2024) 4 SCC 1

Held: A Constitution Bench held that the definition of parties in Section 2(1)(h) read with Section 7 includes both signatory and non-signatory parties, and that the requirement of a written agreement does not exclude the possibility of binding a non-signatory. The group of companies doctrine forms part of Indian arbitration jurisprudence and is founded on the mutual intention of the parties rather than on the phrase claiming through or under, which relates to derivative claims and is a distinct concept. In applying the doctrine the court or tribunal considers the mutual intention of the parties, the relationship between the signatory and the non-signatory, the commonality of the subject matter, the composite nature of the transaction, and the performance of the contract. The conduct of the non-signatory in negotiation, performance or termination may show that it is a veritable party. Membership of the same group of companies is not by itself sufficient, and the alter ego or piercing of the corporate veil principle is distinct, since it disregards corporate separateness whereas the doctrine respects it and looks for consent.

Significance: The judgment settles the basis of the doctrine as consent, keeps it separate from veil piercing, and leaves its application in the first instance to the arbitral tribunal.

📖 ONGC Ltd. v. Discovery Enterprises (P) Ltd., (2022) 8 SCC 42

Held: A non-signatory may be bound by an arbitration agreement where the factors point to such an intention: the mutual intent of the parties; the relationship of a non-signatory to a signatory; the commonality of the subject matter; the composite nature of the transaction; and the performance of the contract. The Court also held that an arbitral award which ignores vital evidence bearing on these questions is liable to be set aside.

Significance: The five factors set out here were adopted and refined by the Constitution Bench, and they are the checklist used in practice.

4. Other Routes to Binding a Non-Signatory

Agency. Where the signatory contracted as agent for a disclosed or undisclosed principal, the principal is bound by the clause on ordinary principles of agency under the Indian Contract Act, 1872.
Assignment. The benefit of a contract carrying an arbitration clause passes with the assignment, and the assignee takes the clause with the right assigned; a novation, by contrast, substitutes a new contract and the clause survives only if the new agreement contains or adopts it.
Succession and representation. Section 40 keeps the agreement alive on the death of a party and makes it enforceable by or against the legal representative.
Subrogation. An insurer who has indemnified the assured and sues in his place stands in his shoes, including as to the arbitration clause.
Guarantees and related instruments. A guarantor is bound by an arbitration clause in the guarantee he executed; he is not bound by the clause in the principal contract merely because the guarantee refers to it, unless the reference incorporates it within Section 7(5).
Alter ego. Where the corporate form has been used as a device to evade obligations, the veil may be lifted. This is an exceptional jurisdiction resting on abuse, and is not the same as the consent-based doctrine described above.

5. Who Decides Whether a Non-Signatory Is Bound

The question is one of fact and inference, and it is for the arbitral tribunal in the first instance. At the stage of Section 8 or Section 11 the court examines only the prima facie existence of an arbitration agreement, and the Constitution Bench in Cox and Kings expressly left the application of the doctrine to the tribunal under Section 16. A non-signatory joined to the reference may take the point before the tribunal, and if it fails, may raise it again under Section 34(2)(a)(iv), on the ground that the award deals with a dispute not falling within the terms of the submission, or under Section 34(2)(a)(i) where the challenge is to the existence of an agreement binding on him.

⚠ The doctrine is an inclusion, not an extension

The doctrine does not extend an arbitration agreement to a stranger. It identifies a person who, on the evidence, was always a party to it although he did not sign. That is why the test is mutual intention, why conduct during negotiation and performance matters, and why membership of a corporate group is never enough by itself. A person who took no part in the negotiation, performed nothing under the contract and derived no benefit from it cannot be drawn into the reference, and the tribunal has no power over him.

6. Practical Points

Where a transaction is to be implemented through several agreements, name all the entities as parties to a single arbitration clause, or reproduce the same clause in each agreement with provision for consolidation.
Where a parent negotiates and a subsidiary signs, record in the agreement which entities are intended to be bound, since the question later turns on evidence of intention.
A party seeking to join a non-signatory should plead the five factors specifically and lead evidence on negotiation, performance and termination, because an award that ignores such evidence is vulnerable under Section 34.
A non-signatory resisting joinder should take the objection before the statement of defence under Section 16(2), since a plea taken late may be shut out unless the tribunal finds the delay justified.
