The Russian Federation's aggression against Ukraine, which began in February 2014, resulted in the occupation of part of Ukraine's territories - the Autonomous Republic of Crimea (hereinafter referred to as Crimea) and the city of Sevastopol. A month after that, the Russian Federation announced the annexation of these territories and, in violation of international humanitarian law, extended its legislation to them, considering the Crimean peninsula part of the Russian Federation. Russian courts, law enforcement agencies, etc. have been established and are functioning on the peninsula. In particular, the so-called bar self-government bodies controlled by the occupation authorities were established, and the activities of lawyers in these territories became possible only if they obtained the right to practice law in the Russian Federation. At the same time, many of these people continue to be lawyers who hold Ukrainian certificates of the right to practice law.
