Global constitutionalism or constitutionalization of the law of integration associations?
One of the phenomena of modern International Law is its fragmentation. This phenomenon has been studied in detail at the doctrinal level in both Russian and foreign science, and is reflected in the report of the working group of the UN Commission on International Law. Russian theory pays less attention to the process of constitutionalization of International Law, which is considered to be inextricably linked to its fragmentation and opposed to it. The author aims to explore existing approaches to the constitutionalization of General International Law and the law of integration associations on the example of the European Union. Using the method of comparative analysis, a conclusion is formulated about the beginning of the constitutionalization of the law of the Eurasian economic Union. The review of the concept of constitutional pluralism prevailing in the legal doctrine of the European Union allows us to conclude that this model is acceptable for understanding the interaction of the national constitutional law and order of the member States of the Eurasian economic Union and the integration association.
