Constitutional law and legal culture are fundamental and, at the same time, interdependent elements of the legal system of a state. The relevance of research on the development of constitutional law in the context of legal culture is dictated not only by the needs of developing the theory and doctrine of constitutional law but also by contemporary legislative practice and law enforcement, within which a utilitarian approach often prevails. According to this approach, when determining the priorities of legal regulation and the state's legal policy, the goals and tasks that do not sufficiently take into account the achievements and the general level of legal culture of Russian society are placed at the forefront. Meanwhile, legal culture largely shapes the communication for effective interaction between the state and the citizen, civil society institutions. It is the starting environment in which constitutional law ideas are born and developed. At the same time, legal culture significantly determines how these ideas are implemented, as well as specific norms of constitutional law. Such close connections between constitutional law and legal culture direct the analysis of constitutional law in a broad sense as a phenomenon that includes not only the norms and institutions of constitutional law but also the objectified constitutional law culture. Research in this direction also allows us to identify that violation of the specified interrelations has negative consequences for the development and functioning of the legal state model in our country.
