Also in June, the Supreme Court was asked to decide whether to review the Ninth Circuit's decision in Monster Energy Co. v. City Beverages, LLC, in which, on the basis of arbitrator bias, the Ninth Circuit vacated an arbitration award after the arbitrator failed to disclose his ownership interest in the company that administered the arbitration. Clarity on this point would help parties decide whether to challenge arbitrators for insufficient disclosures, while also providing arbitrators with further guidance on disclosure requirements. On June 29, 2020, however, the Court refused to review Monster Energy. But another Supreme Court may help in this regard instead. Earlier in June, in an appeal of Halliburton Company v Chubb Bermuda Insurance Ltd [2018] EWCA Civ 817, the UK Supreme Court was asked to decide whether an arbitrator in an insurance matter involving the Deepwater Horizon incident should have disclosed his multiple prior appointments involving that same matter.
