Constantine Partasides QC will present on “Halliburton v Chubb: lessons to be learned on Arbitrators’ duties.” The English Supreme Court judgment issued in Halliburton v. Chubb on 27 November 2020 unanimously dismissed Halliburton’s appeal regarding the circumstances of the arbitrator’s appointment and doubts as to his impartiality. Constantine led the ICC Court’s submissions, as intervener, in this matter before the Supreme Court.

During this event, Constantine will discuss the judgment, its implications, and the interrelationship between the duty to disclose matters relevant to impartiality and the duty of confidentiality in those other arbitrations. He will also discuss the effect on both duties of the particular arbitral context: what rules and what type of arbitration.

The webinar will take place on Wednesday 2 June, at 1:00 pm CDT (BST – 5) and is hosted by the Arbitration Commission of the Mexican Bar Association.
