The Russian Justice Ministry refused Ferat Sayfullaev convicted in the so-called Sevastopol "Hizb ut-Tahrir case" in transferring him to the mainland of Ukraine, lawyer Edem Semedlyaev informed on his Facebook page on May 8, citing a copy of a letter he received from the Russian Ministry of Justice.

“I received a letter from the political prisoner of the Crimean Tatar-Muslim Ferat Sayfulaev. He writes that his detention in the chamber-type room was extended for another six months because he allegedly cleaned up in the cell not properly. All this is done to isolate Ferat from other prisoners in order to break Ferat with loneliness," the lawyer said.

Sayfullaev also sent a copy of a letter from the Ministry of Justice of the Russian Federation that refused his transfer to Ukraine, referring to the Convention on the Transfer of Sentenced Persons of 1983.

"However, taking Crimean Tatars from the Crimea to judge in military courts, no one is guided by Conventions, Resolutions and international treaties. This is how one-sidedly they use international legal acts against Crimean Tatar Muslims," the lawyer said.

Reference: January 23, 2015 in the Crimea  Muslims Ruslan Zeytullaev, Rustem Vaitov, Yuri (Nuri) Primov and Ferat Sayfullaev were detained. They were accused of involvement in the organization "Hizb ut-Tahrir" banned in Russia. Since June 1, their case is being examined in the North Caucasus District Military Court, RF.

On September 7, 2016, the Rostov-on-Don court sentenced four Crimeans to imprisonment for alleged involvement in the organization Hizb ut-Tahrir, which is recognized as terrorist in Russia.
