Interaction of national law and foreign law

The article reveals the principles of choosing between the use of domestic and international legal regulation, when there are differences in the regulation of the same legal relationship. At present, it is difficult to name such social relations that would be exclusively within the competence of states. The boundaries of the spheres of international and domestic law, public and private law are becoming less and less clear, which is a consequence of the interdependence of capital and political power. The development and effective implementation of law is achieved only when there is an internal consistency of its constituent elements, including and above all the norms of law themselves. Without such an agreed system, it is impossible to successfully implement the functions of law, to ensure the regulatory impact of its norms on social relations.
