Under the procedural guidance of the Office of the Prosecutor General, an indictment has been sent to court against 12 senators of the Federation Council of the Federal Assembly of the Russian Federation, accused of aiding in the conduct of an aggressive war against Ukraine and encroaching on its territorial integrity and inviolability (part 5 of article 27, part 2 of article 437; part 3 of article 110 of the Criminal Code of Ukraine).

The investigation established that on February 22, 2022, the aforementioned individuals, acting intentionally and in coordination, supported the decision of the highest military-political leadership of the Russian Federation by participating in a meeting of the Federation Council, during which they approved resolutions on: the ratification of the so-called "treaties on friendship, cooperation, and mutual assistance" between the Russian Federation and the pseudo-entities "LPR" and "DPR"; permission for the use of the armed forces of the Russian Federation outside the territory of the country.

Such actions created legal preconditions for the commencement of armed aggression against Ukraine.

Furthermore, on October 4, 2022, the senators, being aware that the Donetsk, Luhansk, Zaporizhzhia, and Kherson regions are an integral part of the territory of Ukraine, ensured the adoption of federal constitutional laws that "ratified" the so-called treaties on the "accession" of these temporarily occupied territories to the Russian Federation.

Such decisions of the Federation Council contributed to the illegal alteration of the state border of Ukraine, the violation of its sovereignty and territorial integrity, and also created a legal basis for the further annexation of Ukrainian territories.

The pre-trial investigation was conducted by investigators of the Main Investigative Department of the Security Service of Ukraine with operational support from the SBU.

Since the beginning of 2025, the Office of the Prosecutor General has sent indictments to court regarding 62 senators of the Federation Council of the Russian Federation involved in the legitimization of aggression and the annexation of Ukrainian territories.
