MCGM engaged M/s R.V. Anderson Associates Ltd., a Canadian engineering firm, for consultancy services to upgrade Mumbai's sewerage operations under a World Bank-funded contract dated 18.09.1995. After completion of work and a dispute over outstanding dues, the Respondent invoked arbitration in August 2005 under Clause 8.3(b) of the Agreement. The parties each appointed a nominee arbitrator, but the Co-Arbitrators did not appoint a Presiding Arbitrator within the contractually stipulated 30 days. MCGM raised no objection across three successive appointments of the Presiding Arbitrator by the Co-Arbitrators (Justice D.R. Dhanuka (Retd.), Mr. John Savage, and finally Mr. Anwarul Haque), and even participated in the preliminary meeting of the Tribunal in January 2009. Only thereafter did MCGM write to the Presiding Arbitrator alleging his appointment was a 'nullity', and subsequently filed an application under Section 16 of the 1996 Act. The Tribunal dismissed the Section 16 application; the final award dated 05.06.2010 directed MCGM to pay substantial amounts in USD and INR. The Single Judge dismissed MCGM's Section 34 petition, and the Division Bench dismissed the Section 37 appeal. The Supreme Court dismissed the civil appeals, affirming both courts below on two independent grounds.
First, on interpretation of Clause 8.3(b), the Court held that the provision enabling parties to approach the Secretary General of ICSID for appointment of the third arbitrator is an enabling, not a restrictive, clause — triggered only upon a request by either party. Since neither party approached the ICSID, the Co-Arbitrators' power to appoint the Presiding Arbitrator was never extinguished. Reading the clause otherwise would produce commercial absurdity, leaving the Co-Arbitrators in indefinite limbo. The Court agreed with the Tribunal's interpretation as the only plausible view, reiterating the narrow scope of interference under Sections 34 and 37 as affirmed in Consolidated Construction Consortium Limited v. Software Technology Parks of India (2025 INSC 574) and SEPCO Electric Power Construction Corporation v. GMR Kamalanga Energy Ltd. (2025 INSC 1171).
Second, and significantly, the Court held that even where statutory waiver under Section 4 is not technically attracted (because the Section 16 application was filed within the timeline under Section 16(2)), a party's prior conduct of acquiescence remains a powerful and relevant consideration when the Tribunal and courts adjudicate the Section 16 challenge on merits. MCGM's silence across three appointments, its agreement to keep proceedings in abeyance for mediation, and its failure to ever suggest approaching the ICSID, all demonstrated that it never actually understood the clause in the restrictive manner it later urged. The Court coined the phrase "jurisdictional ace" to describe — and condemn — the tactic of reserving a jurisdictional objection while acquiescing in the process, only to deploy it after an adverse award.
