The core issues revolve around whether a Section 21 notice (invoking arbitration) and inclusion in a Section 11 application (for arbitrator appointment) are prerequisites for an arbitral tribunal to exercise jurisdiction over a party. The court examines the source of an arbitral tribunal’s jurisdiction, particularly concerning non-signatories to an arbitration agreement, and clarifies the scope of inquiry under Section 16 of the Arbitration and Conciliation Act, 1996 (ACA). Ultimately, the Supreme Court overturns the lower court’s decision, asserting that non-signatories can be impleaded if their conduct indicates a binding consent to the arbitration agreement.
Arbitration and Conciliation Act, 1996, 21, 11 and 16 – Arbitration proceedings – Impleadment – Whether the service of notice invoking arbitration under Section 21 of the Act, 1996 on a person and joinder of such person in the application under Section 11 for appointment of arbitrator are prerequisites for an arbitral tribunal to exercise jurisdiction over him, and further, when can an arbitral tribunal implead a person to the arbitration proceedings – Held that a notice invoking arbitration under Section 21 of the ACA is mandatory as it fixes the date of commencement of arbitration, which is essential for determining limitation periods and the applicable law, and it is a prerequisite to filing an application under Section 11 – However, merely because such a notice was not issued to certain persons who are parties to the arbitration agreement does not denude the arbitral tribunal of its jurisdiction to implead them as parties during the arbitral proceedings – The purpose of an application under Section 11 is for the court to appoint an arbitrator, so as to enable dispute resolution through arbitration when the appointment procedure in the agreement fails – The court only undertakes a limited and prima facie examination into the existence of the arbitration agreement and its parties at this stage – Hence, merely because a court does not refer a certain party to arbitration in its order does not denude the jurisdiction of the arbitral tribunal from impleading them during the arbitral proceedings as the referral court’s view does not finally determine this issue – The relevant consideration to determine whether a person can be made a party before the arbitral tribunal is if such a person is a party to the arbitration agreement – The arbitral tribunal must determine this jurisdictional issue in an application under Section 16 by examining whether a non-signatory is a party to the arbitration agreement as per Section 7 of the ACA – Respondent nos. 2 and 3 are parties to the arbitration agreement in Clause 40 of the LLP Agreement despite being non-signatories – Their conduct is in accordance with and in pursuance of the terms of the LLP Agreement, and hence, they can be made parties to the arbitral proceedings – Impugned judgment and order of the High Court liable to be set aside – Proceedings must be continued from the stage of arbitral tribunal’s order dated 15.02.2024.
