On the integrity of law: interaction of private and public principles in the economy

Law as legislation consists of branches, which allows its norms to be applied in the socio-economic life of society. However, complex in composition and time-consuming in execution types of products manufactured for the needs of the state require the interaction of different arrays of legal norms, such as public and private, in terms of the method of regulating social relations. The article attempts to show, using the example of purchases under the state defense order, how the unity of state and legal regulation in a state contract under the state defense order is achieved. Public law and private law are considered not only as different in the method of influencing public relations, but also in interaction. At the same time, the fundamental categories of public law cannot be interpreted as civil law (private power).
