It is usual to write about law as a system. The systemacity of the law means only a modicum of orderliness and a network of legal norms as basic elements of legal system. There is always a degree of contradiction and/or a tension between legal norms, legal principles and other elements of the legal system. This tension and/or contradiction are characteristic and system creating relationship between elements of Manual system. Legal system is not an axiomatic one for many reasons. It is full of unavailable tensions and contradictions. It is a social normative system determined by society. The elementary unit connecting legal system and social system is legal regulation of great amount of social acts and consequently of social relations, which acquire quality of legal relations. It is also an information (sub) system. Law always strives for an order, but only with a moderate success. It is an open cognitively and operationally open system.
