Tamara Morshchakova, a renowned Russian legal scholar, former Russian Constitutional Court judge and member of the Russian Presidential Human Rights Council, has been called for questioning by investigators, RIA Novosti has reported. The questioning is reported to be about the Council’s 2011 inquiry and report into the second Khodorkovsky trial.

Nine experts — six Russian and three foreign — were invited to take part in the Council’s inquiry, which identified serious and widespread violations of the law in the second Khodorkovsky trial. The inquiry found that there was no valid legal basis or evidence supporting the guilty verdict, and that the proceedings were severely marred by violations of fundamental human rights. More broadly, the inquiry found that the case highlighted widespread systemic problems in Russia’s law enforcement practices and judiciary. The findings prompted calls for an annulment of the “illegal” guilty verdict and the release of Khodorkovsky and Lebedev, and also for a series of reforms to address the systemic problems illustrated by the case.

The inquiry’s findings are profoundly uncomfortable for those in power in Russia and in recent months the Russian experts who took part in the inquiry, including Sergei Guriev, have faced interrogations from investigators. The questioning of Morshchakova, who coordinated the compilation of the report, is reported to be taking place on Thursday, June 27.
