The Russian Supreme Court has reduced by two months the eleven-year sentence on former Yukos CEO Mikhail Khodorkovsky and his business partner Platon Lebedev.

The court partially upheld the appeal of the convicts and their defense on Tuesday, an Interfax correspondent reports. The prison time of Khodorkovsky will now end in August 2014, and Lebedev will be released from custody in May 2014.

The Supreme Court declined to repeal the sentence or reduce the prison time to the already served and release the convicts from custody.

Khodorkovsky and former Menatep Group head Lebedev were arrested in 2003 and sentenced to nine years in May 2005 on the fraud and tax evasion counts. The Moscow City Court reduced their sentences to eight years later.

The second criminal case was opened against Khodorkovsky and Lebedev when their first trial was nearing completion. The former Yukos executives were sentenced in December 2010 to 14 years for crude embezzlement and money laundering. Six months later the Moscow City Court reduced their sentences to 13 years.

The prison term was calculated from 2003, since the day of their arrest in the first Yukos case.

Khodorkovsky and Lebedev appealed to Russian Supreme Court Chairman Vyacheslav Lebedev in June 2012 to repeal their second sentence. The Supreme Court chairman processed their appeal and initiated a supervisory review. His resolution was delivered to the Moscow City Court in August. The Moscow City Court Presidium pronounced the sentence lawful in December but cut the sentences to eleven years in line with the adjustments made to the Criminal Code.

The defense of the former Yukos executives appealed their second sentence at the Russian Supreme Court on February 4, 2013. The defense asked for the overruling of the sentence passed by the lower-tier court and consequent judgments, including the one passed by the Moscow City Court Presidium on December 20, 2012, to cut the prison time of the clients.
