Vinnik has joined the court proceeding, which was 45 minutes late, with his three lawyers — Frederic Belot, Ariane Zimra and Zoe Konstantopoulou.
Belot has previously said that the case consideration would be taking place on 19-22 October.
Vinnik was detained in Greece in 2017 at the request of the United States, which accused him of laundering $4 billion worth of funds through a cryptocurrency trading platform. France also filed charges against Vinnik, however, his lawyer claimed that it was only a ploy to have him extradited to the United States. Vinnik was extradited to France earlier this year. Russia has submitted a separate extradition request.
Vinnik has denied committing any criminal or administrative offences.
