Supreme Court Allows Non-Signatories to Join Arbitration Where Their Rights Are Substantially Affected

The Supreme Court held that the absence of a signature on an arbitration agreement does not invariably exclude a person whose conduct, relationships and interests connect them to the underlying dispute.

Background and legal issue

The controversy arose when the Bombay High Court declined to permit the addition of persons who had not formally signed the arbitration agreement. Their participation depended on whether they could properly be treated as parties in substance.

Court's reasoning and legal position

Justices J B Pardiwala and K Vinod Chandran rejected a rigid signature-only test. The inquiry must consider whether the person intended, through conduct and connection with the contracting parties, to be bound and whether the award may substantially affect their rights.

Operative effect and next step

The Supreme Court set aside the exclusionary approach and restored the question of participation to the applicable fact-sensitive analysis. Non-signatories are not automatically parties in every arbitration.
