The lawyers of Mikhail Khodorkovsky's business partner Platon Lebedev submitted on Friday a parole request with a court in the Arkhangelsk Region, the press center of the former Yukos oil company officials said on its website.
"Today, lawyer Yelena Liptser submitted a request with the Velsk District Court to release Platon Lebedev on parole," the press center said in a statement.
Lebedev was transferred to the pre-trial detention center from Penal Colony 14 in the Arkhangelsk Region's city of Velsk in northwestern Russia.
Khodorkovsky and Lebedev's lawyers already requested paroles for their clients but the Preobrazhensky Court in Moscow denied both requests.
On Friday Lebedev used a video conference from the pre-trial detention center in Arkhangelsk to take part in a meeting of the presidium of Moscow City Court.
Lebedev told the court that Judge Viktor Danilkin illegally extended his detention in a pre-trial centre between May 17 and August 17, 2010. However, the court approved the decision.
Lebedev is serving a 13-year sentence for oil embezzlement and money laundering.
Khodorkovsky, the former head of Yukos oil company convicted of embezzlement and tax fraud, appealed against his sentence and a second trial in Moscow. He was sentenced to an additional six years on top of his initial eight year sentence by a Moscow court in December 2010, later reduced by one year. He is now due for release in 2016.
The two men have denied all charges against them, saying that they were revenge for Khodorkovsky's funding of opposition parties during the presidency of Vladimir Putin, something the Russian authorities categorically deny.
