The next hearing on the case on $2 billion will be held in early 2016.
Former shareholders of TNK-BP Leonard Blavatnik and Viktor Vekselberg believe that they settled accounts with the senator from Chuvashia Leonid Lebedev in 2003, when they agreed to transfer $600 million to him.
In his lawsuit, the MP argues that under the old arrangements he was entitled to get 7.5% from $28 billion received from AAR Consortium for the sale of shares in TNK-BP.
