Representatives of the Respondent(s)

Russia has not appointed any representatives. By letters dated 12 August 2015 and 15 September 2015 (received by the PCA on 18 September 2015), the Russian Federation indicated, inter alia, that the “[Ukraine-Russia BIT] cannot serve as a basis for composing an arbitral tribunal to settle [the Claimants’ claims]” and that it “does not recognize the jurisdiction of an international arbitral tribunal at the Permanent Court of Arbitration in settlement of [the Claimants’ claims].” The Russian Federation also stated that nothing in its correspondence “should be considered as consent of the Russian Federation to constitution of an arbitral tribunal, participation in arbitration proceedings or as procedural actions taken in the framework of the proceedings.”
