For jurisprudence (doctrine and practice), the fundamental question of the principles of the nature of law is at the same time the question of the normative (special-legal) composition of law, the structure of its normative “substances" or a set of legal regulators. From the position of dominant views, legal regulators a priori recognize norms, or legal rules that are positive in legislation. This paradigm, which remains unshakable, is the basis of the assessment mechanism, the formed stable attitude to understanding the forms (sources) of law, the practice of making law enforcement decisions in situations of lack of legislation, as well as emerging defects in legal regulation, the need (validity) of the applicable norms. Rooted in Russian jurisprudence understanding of the principles of law as legal ideas” or more “general norms”, while the latter are not presumed as a legal basis for making individual legal decisions in resolving specific cases, is hopelessly outdated and does not correspond to the needs of developing practice. A paradigm change regarding understanding the structure and composition of regulators of law objectively requires a solution to an issue of fundamental importance, a kind of sui generis, the answer to which the pillars of philosophy and theory of law tried to answer (L.A. Hart, R.ºDvorkin, M. van Hook, R. Alexi, etc.): whether the law consists only of norms or are they a part of this whole; whether the norms of law are always perceived by law enforcement authorities, primarily by the courts, as the only legal basis, given that the norm to be applied is either absent, or differs in legal uncertainty, inconsistency, that is, is invalid.
