The human activities are regulated activities, guided also by a complex normative-legal system, designed to promote the further development of the social life, to improve its quality. To this extent, a great importance pertains to the establishment of the field and limits of the action of law. Far from being an abstract notion or from being completely figured out, this issue requires, no doubt, a special focus on it. The successful and efficient solving of it allows, first, considerably broadening the usage of the possibilities of law in view of stimulating the legal activities of the human beings, second, to determine the categories and the kinds of the social behavior, which apparently are being legal, in fact being illegal by their nature and consequences.
