Arbitration Appeal under Section 37, Arbitration and Conciliation Act, 1996 — dismissed. Affirming the learned Single Judge's order dated 30 April 2024 setting aside the Majority Award dated 8 August 2017 and upholding the dissenting Award dated 14 August 2017, the Division Bench held: (i) the Appellant confirmed all trades after execution over about three months (July–September 2015), signed the final ledger and accepted Rs.37,829.69/- without demur, objecting first only after about ten months — such conduct showed knowledge, consent and waiver; (ii) pre-trade confirmation became mandatory only by the SEBI Circular dated 26 September 2017 (compulsory for equity from 1 January 2018), and violation of NSE (F&O) Regulation No.3.4.1 could at highest attract penal action against the broker, not release a constituent from confirmed trades; absence of pre-trade authorisation differs from blatantly unauthorised trades; (iii) the majority award, being cryptic and ignoring vital material, was perverse and rightly set aside; even applying OPG Power Generation principles to documents ignored by the tribunals worsened the Appellant's case; (iv) the scope of appeal under Section 37 is co-terminus with Section 34 powers, and the Single Judge had not travelled beyond it. Nirmal Bang Securities (Cal HC), Keynote Capitals and Maheshbhai Champneira relied on; Amit Bhardwaj, Bonanza Commodities and OPG distinguished; Girijanandini Devi and P.R. Shah referred.
