The subject of the study is the extension of the principle of federalism on the validity of the Code of Administrative Offences of the Russian Federation. The paper raises the issue of its extension to normative legal acts adopted by the public authorities of the constituent entities of the Russian Federation and municipal normative legal acts. The author has analyzed the decisions of courts of different levels on bringing to administrative responsibility on the basis of the Administrative Code of the Russian Federation for violations of the law rules of constituent entities of the Russian Federation. The article contains conclusions about the need to correct the provisions of Article 1.3 of the Administrative Code of the Russian Federation. The proposed design of the norm will clearly delineate the powers of the Russian Federation and the constituent entities of the Russian Federation in determining administrative responsibility and excluding the possibility of brining to administrative responsibility for the violation of normative legal acts of constituent entities of the Russian Federation and municipal bodies on the basis of the rules of the Administrative Code of the Russian Federation.
