Arbitrator and Performance Standards in Multiparty Arbitrations

November 2025
ArbitrationGeneral

Abstract

Much of the action and decisions in multiparty construction arbitrations are rooted in the arbitral tribunal’s performance. The arbitral tribunal’s performance standards are contextualised of the arbitrator’s case management skills and posits some institutional policy considerations in the appointment of a sole arbitrator. Analysis further illuminates into selective judicial standards that can be appropriated for the arbitrator’s successful handling of the regime. Ultimately, the present theme overviews the ties of the joinder regime with a locus and a national legal system in order to assert if the latter procedural fuels can empower the multipartite regime.
