The SC in Oil and Natural Gas Corporation Limited v. Discovery Enterprises Pvt. Ltd. & Anr.[1], held that a non-signatory company within a group of companies can be bound by an arbitration agreement. The SC, while deciding on a challenge to an interim award passed by the arbitrator held that a non-signatory party / company may be tied to the agreement to arbitrate if it is an alter ego of a party which executed the agreement. The Court observed that although consent and party autonomy are enshrined in Section 7 of the Arbitration Act, it does not exclude the possibility of an arbitration agreement binding a third-party.
