The article proves that law is an effective means of regulation only in the rule of law. The rule of law underpins the work of the United Nations and other international organizations, as well as the political institutions of modern developed nations. It is shown that the concept of “rule of law” is lexically close to one of the basic elements of the positivist doctrine of law in the form of the concept of “rule of law”, which led to the identification of these concepts. It is substantiated that the Ukrainian vision of the rule of law is not limited to legislation as one of its forms, but also includes other social regulators, including morals, traditions, customs, etc., which are legitimized by society and conditioned with historically achieved cultural level. It is confirmed that justice is one of the basic principles of the law, decisive in defining it as a regulator of social relations, one of the universal dimensions of the law. It is proved that justice is considered as a property of the law, expressed, in particular, in the equal legal scale of behavior and in the proportionality of legal responsibility for the offense. In the field of the law enforcement, justice is manifested, in particular, in the equality of all before the law, the conformity of crime and punishment, the goals of the legislator and the means chosen to achieve them. In the article, that right, comes forward as effective means of adjusting only in the conditions of supremacy of thelaw. Principle of supremacy of right is the basis of activity of United Nations and other international organizations, and also political institutes of the modern developed states. It has been shown that a pan-European understanding of the concepts studied takes into account the main aspects of the concept of “rule of law”: all persons, whether public or private, must be bound by law and have the right to enjoy it. It is shown that modern society has developed an effective mechanism for ensuring the rule of law, which includes: the existence of the basic law of the country – the Constitution or its equivalent; clear and consistent system of legislation; institutions of justice, administration and security, which have the means and capabilities to ensure the application of legislation; legal culture. In the absence of equal law for all, the progressive development of society is impossible. Where there are groups above the law, as well as the practice of selective application of the law, incentives for development disappear. It is substantiated that the rule of law should be identified and implemented at the stage of law enforcement and the first step towards this is to increase the role of law as the main and primary regulator of public relations.
