This Practice Note considers the availability of state (sovereign) immunity as a defence to enforcement of an arbitral award in Russia under Russian law. It considers provisions of the Civil Procedural Code of the Russian Federation, Arbitrazh Procedural Code of the Russian Federation and the Federal Law No 297-FZ ‘On jurisdictional immunities of foreign state and property of foreign state in the Russian Federation’. The Practice Note considers the application of the United Nations Convention On Jurisdictional Immunities of States and Their Property and the question of the state voluntarily waiving its immunity.
