THE AUTHOR<\/strong>: Arbitration fundamentally rests upon the consent of the parties. Traditionally, in India<\/a>, this consent has been strictly interpreted, restricting arbitral proceedings solely to those who are parties to the arbitration agreement. However, with the ever-increasing complex commercial arrangements, especially within corporate group structures, entities closely involved in the transaction, yet formally not part of the arbitration agreement, may be required to be impleaded to effectively adjudicate the \u2018lis<\/em>\u2019. This scenario has led to the judicial development of doctrines such as \u2018Group of Companies\u2019 and \u2018Single Economic Transaction\u2019 to address the challenge of impleading non-signatories. This article navigates through the evolution of the concept of impleading non-signatories by examining the nuanced jurisprudence and legislative developments, particularly the Arbitration Amendment Bill, 2024.<\/p>\n\n\n\n Initially, Indian courts showed hesitation in allowing non-signatories to be impleaded by arbitral tribunals. The hesitation was based on the then understanding of the provisions of the Arbitration and Conciliation Act, 1996 (“the Act<\/strong>“), which were interpreted by Indian Courts to emphasise party autonomy and explicit consent. The judicial consensus was that arbitral tribunals had no independent power to join non-signatories, unlike Courts under Order 1 Rule 10 of the Code of Civil Procedure, 1908 and that no implicit power can be inferred from Sections 16, 17 or 19 of the Act, providing inherent or residuary powers to the Arbitral Tribunals under the Act, to implead non-signatories (see Sukanya v. Pandya and another<\/em>, 14 April 2003<\/a>).<\/p>\n\n\n\n The Supreme Court’s landmark decision in Chloro Controls India Pvt. Ltd. v. Severn Trent Water Purification Inc. <\/em><\/strong>(28 September 2013)<\/a> marked a significant shift. Adopting the “Group of Companies” doctrine, the Court acknowledged that non-signatories could be bound to arbitration agreements within composite transactions if implied consent and mutual intention were demonstrable. However, the Court clarified that this power of joinder remained exclusively judicial, stopping short of recognising similar powers for arbitral tribunals.<\/p>\n\n\n\n Subsequent rulings expanded the scope introduced by Chloro Controls, while holding that only the Courts can implead non-signatories to an arbitration. Delhi High Court in Arupri Logistics Pvt. Ltd Vs. Vilas Gupta & Ors <\/em><\/strong>(2023, Reported as (2024) 308 DLT 327), reiterated that Arbitral Tribunals have no inherent powers under the Act to implead non-signatories, and the doctrine of alter-ego or group of companies cannot be exercised by Arbitral Tribunals, in the absence of a statutory framework.<\/p>\n\n\n\n The constitutional bench of the\u2009Supreme Court issued\u2009its decision in\u2009 <\/em><\/strong>Cox & Kings Ltd. v. SAP India Pvt. Ltd<\/em><\/strong>.<\/a> (6 December 2023) to\u2009establish a pivotal\u2009transformation in legal\u2009interpretation. While endorsing the Group of Companies doctrine, the Supreme Court interpreted the doctrine of Kompetenz-Kompetenz<\/a> under Section 16 of the Act to also include the power to decide whether an arbitration agreement exists with a third party. While this decision marked a paradigmatic shift, the observation of the Court that \u201cthe referral Court should leave open the issue whether a non-signatory is bound by the arbitration agreement for the Arbitral Tribunal to decide<\/em>\u201d resulted in further litigation, with one school of thought, arguing that the Arbitral Tribunal can implead a non-signatory, only if such an issue is specifically left open by the referral Court (under Section 8 or 11 of the Act) for the Arbitral Tribunal to decide.<\/p>\n\n\n\n The much-needed clarity came in the form of the Supreme Court\u2019s judgment in ASF Buildtech Vs Shapporji Pallonji & Company Pvt. Ltd<\/em>, 2025 SCC Online SC 1016 (\u201cASF Buildtech<\/em><\/strong>\u201d). The Supreme Court cemented arbitral tribunals’ authority by unequivocally clarifying that tribunals possess independent jurisdiction to determine and join necessary parties, including non-signatories. This ruling resolved residual ambiguities, underscoring the expansive interpretation of tribunal autonomy under Section 16 of the Act, even absent initial judicial intervention. The Supreme Court relied upon the decision in Cox & Kings I<\/em> and held that since the terms \u201cparty\u201d and \u201carbitration agreement\u201d used in Section 2(1)(h) and Section 7 of the Act, respectively, are not confined to \u201ccourts\u201d or \u201ctribunal\u201d, an arbitral tribunal has the power to implead a non-signatory, if that person is found to be bound by the arbitration agreement.<\/p>\n\n\n\n The Supreme Court\u2019s decision in ASF Buildtech<\/em> is a step in the right direction and is in line with internationally accepted practices. The power of the arbitral tribunal to implead non-signatories is not a novel concept. Jurisdictions such as the USA<\/a> and Singapore<\/a> explicitly empower arbitral tribunals to implead non-signatories. Institutional rules, including those of ICC (International Chamber of Commerce)<\/a> and SIAC (Singapore International Arbitration Centre)<\/a>, reflect similar provisions, emphasising procedural flexibility and party autonomy. India\u2019s judicially driven approach increasingly aligns with this international arbitration landscape, although statutory recognition remains absent.<\/p>\n\n\n\n
