Problems of interaction between the constitutional order and international law

The article analyzes the problem of the relationship between the provisions of constitutions and international treaties in constitutional law. Its solution often depends on the prevailing doctrine and case law of the constitutional courts regarding the application of the latter in the light of constitutional principles and rules. This is important for substantiation and decision-making by constitutional justice bodies. In this case, the problem is to decide whether the provisions of international treaties comply with the constitutional order and whether the constitutional justice authorities will use the provisions of international treaties in their activities and borrow elements of argumentation of international jurisdictions. This is the subject of heated debate, especially with the establishment of the European Economic Communities, although there is a specific relationship between international and national law, between supranational and national legal orders, as the nature of the EU is supranational and multilevel.Based on the experience of the constitutional justice bodies, arguments are presented that despite quite contradictory approaches, such can be unified by the Constitutional Court of Ukraine. This can be achieved provided that he solves these problems through the prism of fundamental principles of law, thus ensuring the supremacy of the Constitution of Ukraine and the national identity of Ukraine in the legal geography of the world. The components of such a process are the application by the ССU of the principle of friendly attitude to international law and taking into account national interests, constitutional principles of territorial integrity and independence of Ukraine, human rights guarantees and compliance with due process. The study of Ukraine’s European integration in the light of constitutional principles should be based on the protection of the above values and the effectiveness of human rights, the balance of private and public interests. In the light of harmonization of legislation under the EU-Ukraine Association Agreement, the acquis commumautaires of the European Communities should also be taken into account, in particular the case law of the Court of Justice of EU, which can be used as a basis for reasoning public administration and judicial decisions.
