“24. Following the general rule and the principle laid down in Vidya Drolia [Vidya Drolia v. Durga Trading Corpn., (2021) 2 SCC 1 : (2021) 1 SCC (Civ) 549], this Court has consistently been holding that the Arbitral Tribunal is the preferred first authority to determine and decide all questions of non-arbitrability. In Pravin Electricals (P) Ltd. v. Galaxy Infra & Engg. (P) Ltd. [Pravin Electricals (P) Ltd. v. Galaxy Infra & Engg. (P) Ltd., (2021) 5 SCC 671, paras 29, 30 : (2021) 3 SCC (Civ) 307], Sanjiv Prakash v. Seema Kukreja [Sanjiv Prakash v. Seema Kukreja, (2021) 9 SCC 732 : (2021) 4 SCC (Civ) 597], and Indian Oil Corpn. Ltd. v. NCC Ltd. [Indian Oil Corpn. Ltd. v. NCC Ltd., (2023) 2 SCC 539 : (2023) 1 SCC (Civ) 88], the parties were referred to arbitration, as the prima facie review in each of these cases on the objection of non-arbitrability was found to be inconclusive. Following the exception to the general principle that the Court may not refer parties to arbitration when it is clear that the case is manifestly and ex facie nonarbitrable, in BSNL v. Nortel Networks (India) (P) Ltd. [BSNL v. Nortel Networks (India) (P) Ltd., (2021) 5 SCC 738 : (2021) 3 SCC (Civ) 352] (hereinafter “Nortel Networks”) and Secunderabad Cantonment Board v. B. Ramachandraiah & Sons [Secunderabad Cantonment Board v. B. Ramachandraiah & Sons, (2021) 5 SCC 705 : (2021) 3 SCC (Civ) 335], arbitration was refused as the claims of the parties were demonstrably time-barred.
