The High Court recently declined to lift a stay of the hearing of an application for the enforcement, under the Arbitration Act 1996, of certain arbitral awards and a related jurisdictional objection by the respondent (Russia) on grounds of sovereign immunity. Among other things, a court's powers under the Arbitration Act to order an adjournment of proceedings and the payment of security are not applicable where there is an unresolved state immunity challenge under the State Immunity Act.
