WEBINAR: Policing the Arbitrators (15 July 2021)
Contact SIArb Secretariat, This email address is being protected from spambots. You need JavaScript enabled to view it.
About this Webinar:

An arbitrator’s duty to be impartial is at the heart of his or her role; and maintaining impartiality is essential to enable international arbitration to provide a fair process for resolving disputes. But what does this duty require, and how is it policed?  The English Supreme Court case of Halliburton v Chubb has thrown a spotlight on the interaction between the duty of impartiality and disclosure, particularly in the context of arbitrators accepting multiple appointments, but this is not the whole story.  In this webinar, our three eminent speakers bring experiences as counsel, arbitrator and arbitral institution that bear on this important topic to discuss:

  • what it means to be “impartial”, and how this relates to “independence”;
  • whether an arbitrator’s duty of impartiality should be equated with that of a judge;
  • what recent authorities tell us about the duty of disclosure and impartiality, and how Halliburton v Chubb compares with decisions from other key jurisdictions (such as BYL v BYN [2020] SGHC 6);
  • practical points for counsel/arbitrators to bear in mind when approaching questions of disclosure and conflicts of interest at different stages of a dispute (e.g., at the point of arbitrator appointment, during the arbitration, and at the enforcement or challenge stage); 
  • when an arbitrator’s conduct of the proceedings (as opposed to links to the parties or other participants) may cast doubt on his or her impartiality;
  • the significance of “soft rules” such as the IBA Guidelines and grey areas that remain; and
  • transparency and the role of the institution in policing the arbitrators.
