Under the conditions set out in Part 2 of Art. 19 of the Constitution of Ukraine of the legal order in Ukraine, according to which state bodies to which the National Police of Ukraine belongs, their officials are obliged to act only on the basis, within the powers and in the manner provided by the Constitution and laws of Ukraine, is usually an important issue regulatory and legal regulation of the activities of the bodies of the National Police of Ukraine on ensuring the exercise of the right to freedom of peaceful assembly. The article examines the legal acts, namely the Law of Ukraine “On the National Police”, the Criminal Procedure Code of Ukraine, the Resolution of the Cabinet of Ministers of Ukraine, as well as the departmental regulatory acts of the Ministry of Internal Affairs of Ukraine, the Head of the National Police of Ukraine regarding the right to exercise the right to freedom of peaceful assembly. However, the norms of these acts are too general to organize and ensure the exercise of the right to freedom of peaceful assembly by the National Police of Ukraine. The author believes that the adoption of a separate law on peaceful assembly should be amended accordingly to the Law of Ukraine “On Citizens’ Appeals”, which regulates the authority of the National Police of Ukraine to respond to a message about the intention to exercise the right to peaceful assembly. In addition, the proposed amendments to the Law of Ukraine “On the National Police” will fill in the gaps in the legal regulation of the powers of the National Police of Ukraine to enforce the right to freedom of peaceful assembly.
