Yukos oil giant was accused of tax crimes and declared a bankrupt by a court ruling in 2006 while its assets were sold at auctions during the liquidation procedure.
Yukos former head Mikhail Khodorkovsky and his business partner Platon Lebedev were found guilty of embezzlement and tax evasion in May 2005 and sentenced to nine years in prison.
While serving their prison term, both Khodorkovsky and Lebedev were found guilty of embezzlement and money laundering in a second criminal case in December 2010 and sentenced to 14 years in prison, with account taken of the jail term they had served.
Khodorkovsky was pardoned by Russian President Vladimir Putin and left the prison in December 2013. Lebedev was released from the jail in early 2014.
