The constitutional law system needs to be improved due to the most recent changes. It is necessary to reconsider the concept of the constitutional law system and structure. It is proved that the system of constitutional law forms the internal structure of this branch of law with regard to the current state of social relations that are governed by the norms of constitutional law. The author presents the system of constitutional law in the form of a pyramid: at the top there are the values followed by the principles, then the sub-branches, the institutions and, finally, the bottom of the pyramid is formed by the norms of constitutional law. The author offers her own understanding of classification of constitutional law norms. Particular attention is paid to the development of integrated institutions of constitutional law, including the norms of other branches of law. The author substantiates the necessity of including its principles into the system of constitutional law. The author suggests her own classification of the principles of constitutional law: according to the degree of implementation, according to the sources of consolidation, according to the spheres of regulated constitutional legal relations. The author justifies the need to include values that play an important ideological role penetrating the public legal conscience into the system of constitutional law. Obtaining such values becomes an ultimate purpose of activities performed by citizens and public authorities.
