MOSCOW, April 16 - RAPSI. The defense team of Platon Lebedev, who is serving an 11 year sentence for oil theft, has once again asked the Constitutional Court to clarify the requirements for his release on parole, the Mikhail Khodorkovsky and Lebedev press center said on Tuesday.

Despite a previous Constitutional Court ruling, Archangelsk regional courts have consistently ignored its stance on Lebedev's parole request in their legal practice, his attorneys said.

They earlier asked the Constitutional Court to recognize as illegal the requirement that parole can only be granted to individuals who have pleaded guilty. The court upheld their request.

On March 20, the Arkhangelsk Regional Court's presidium denied Lebedev's parole appeal.

In late 2010, the Moscow's Khamovnichesky District Court sentenced former Yukos chief Khodorkovsky and his partner, former Menatep CEO Lebedev, to 14 years on charges of embezzling 200 million metric tons of oil and of laundering the proceeds.  The sentence was later reduced by one year. On Dec. 20, 2012, the Moscow City Court reduced the sentence from 13 to 11 years.
