MOSCOW, July 16 (RAPSI, Diana Gutsul) - Investigative authorities have permitted Russian lawyers Nikolai Polozov and Mark Feigin, made famous for their former defense work with Russian punk rock group Pussy Riot, to work on the defense team in the Serbian trial of Russian national Ilya Goryachev, suspected of involvement in a Russian extremist movement, Polozov told RAPSI today.

"The Basmanny District Court heard our complaint about the investigator who failed to provide us with permission to the court hearings. However, later it became known that soon after the complaint was filed, we were admitted to Goryachev's trial. The complaint was withdrawn," the lawyers explained.

Polozov pointed out that the Supreme Court of Serbia will hear next Thursday an appeal regarding Russia's extradition request, which was filed by Goryachev's defense.

The Investigative Committee found that Goryachev was put on the international wanted list in relation to criminal charges against extremists from the Militant Organization of Russian Nationalists (BORN) and others. The extremist group is charged with banditry, illegal weapons trafficking, and several cuonts of homicide, including Judge Eduard Chuvashov and lawyer Stanislav Markelov.

Chuvashov was shot and killed in the stairwell of his Moscow apartment building in 2010. During his career with the Moscow City Court, he reviewed over 20 high-profile criminal cases, some of which involved murder on ethnic grounds.

Markelov was shot and killed in Moscow on Jan. 19, 2009. According to the investigation, Markelov was murdered for his active participation in an anti-fascist movement. The group is accused of having attempted 11 murders.
