Selected Experience

  • Ukraine as Respondent in an ICSID arbitration initiated by Emergofin B.V. and Velbay Holdings Ltd. under the Netherlands-Ukraine bilateral investment treaty (ICSID Case No. ARB/16/35). The dispute relates to an aluminium and alumina production company.
  • Two international construction contractors as Respondent in an ICC arbitration in London initiated by a Middle Eastern State-owned company. The dispute concerns the development of a world-class medical facility in the Middle East. The law of the Claimant's State applies.
  • A French-German consortium in an ICC arbitration in Stockholm against a Finnish utility company. The dispute arises from an agreement for the construction a nuclear power plant in Finland. Finnish law governs. Over EUR 6.1 billion is at stake.
  • The majority shareholders in the former Yukos Oil Company as Claimants in a series of three arbitrations against the Russian Federation in relation to the expropriation of their investment in the company. The claims were brought under the Energy Charter Treaty, a multilateral treaty governing trade and investment in the energy sector. The arbitrations were conducted in accordance with the UNCITRAL Arbitration Rules and were administered by the Permanent Court of Arbitration (PCA) in The Hague. In an Interim Award of November 20, 2009, the Arbitral Tribunal decided that it had jurisdiction over the dispute and that the claims were admissible. In a Final Award rendered on July 18, 2014, the Arbitral Tribunal ordered the Russian Federation to pay over USD 50 billion in damages to our clients, which makes this the largest arbitral award ever rendered by an arbitral tribunal. The Tribunal also ordered the Respondent to reimburse to our clients 75% of the legal fees they had incurred in these proceedings, as well as 100% of the arbitration costs. 
  • A Cypriot company as Claimant in two LCIA arbitrations in London against the borrower and the guarantor in a USD 1.6 billion loan to a leading Russian oil and gas company. The Claimant sought payment of the unpaid balance of all sums owing under the loan agreement. English law applied and the language of the proceedings was English. The amount at stake in these arbitrations was in excess of USD 650 million (without interest).
