Arbitration and Conciliation Act,1996; Section 2,7,11– The definition of “parties” under Section 2(1)(h) read with Section 7 includes both the signatory as well as non-signatory parties. Persons or entities who have not formally signed the arbitration agreement or the underlying contract containing the arbitration agreement may also intend to be bound by the terms of the agreement. Further, the requirement of a written agreement under Section 7 does not exclude the possibility of binding non-signatory parties if there is a defined legal relationship between the signatory and non-signatory parties. Therefore, the issue as to who is a “party” to an arbitration agreement is primarily an issue of consent. Actions or conduct could be an indicator of the consent of a party to be bound by the arbitration agreement.- The fact that a non-signatory did not put pen to paper may be an indicator of its intention to not assume any rights, responsibilities or obligations under the arbitration agreement. However, the courts and tribunals should not adopt a conservative approach to exclude all persons or entities who intended to be bound by the underlying contract containing the arbitration agreement through their conduct and their relationship with the signatory parties. The mutual intent of the parties, relationship of a non-signatory with a signatory, commonality of the subject matter, composite nature of the transactions and performance of the contract are all factors that signify the intention of the non-signatory to be bound by the arbitration agreement -An important factor to be considered by the Courts and Tribunals is the participation of the non-signatory in the performance of the underlying contract.- the intention of the parties to be bound by an arbitration agreement can be gauged from the circumstances that surround the participation of the non-signatory party in the negotiation, performance, and termination of the underlying contract containing such an agreement. Further, when the conduct of the non-signatory is in harmony with the conduct of the others, it might lead the other party or parties to legitimately believe that the non-signatory was a veritable party to the contract containing the arbitration agreement. However, in order to infer consent of the non-signatory party, their involvement in the negotiation or performance of the contract must be positive, direct and substantial and not be merely incidental. Thus, the conduct of the non-signatory party along with the other attending circumstances may lead the referral court to draw a legitimate inference that it is a veritable party to the arbitration agreement- (Para 68-71)- But under under Section 11(6) of the Act, 1996 , Court should not conduct a mini trial and delve into contested or disputed questions of fact -Where complexity is involved in the determination of the question whether a party is a veritable party to the arbitration agreement or not, it would be appropriate for the arbitral tribunal to take a call on the question after taking into consideration the evidence that may be adduced by the parties before it and the application of the legal doctrine as elaborated in the decision in Cox and Kings- Referred to Cox and Kings Ltd. v. SAP India Pvt. Ltd. (2024) 4 SCC 1. (Para 79-80)
