The article examines the legal nature of decisions of the Constitutional Court of Ukraine as interpretative legal acts. It is noted that constitutional law-making is a special form (variety) of law-making, which has a multi-level and multi-aspect nature, which is determined by its special nature, essence and functional purpose. Constitutional law-making is a special activity of competent law-making subjects, which is carried out in a special procedural order and is aimed at adopting, changing and canceling the norms of the Basic Law of the state and constitutional acts of law-making. The specificity of the activity of the Constitutional Court of Ukraine is that it does not administer justice in the direct sense. Its powers include: resolving issues of compliance with the Constitution of Ukraine (constitutionality), laws of Ukraine and other legal acts of the Verkhovna Rada of Ukraine, acts of the President of Ukraine, acts of the Cabinet of Ministers of Ukraine, legal acts of the Verkhovna Rada of the Autonomous Republic of Crimea; official interpretation of the Constitution of Ukraine; resolution of questions about the conformity of the Constitution of Ukraine (constitutionality) of the laws of Ukraine (their individual provisions) on the constitutional complaint of a person who believes that the law of Ukraine applied in the final court decision in his case contradicts the Constitution of Ukraine. It is emphasized that the legal positions formulated by the Constitutional Court of Ukraine at making decisions are based on the systematic interpretation of constitutional norms in their interrelationship, the systematic and substantive analysis of constitutional provisions. However, the interpretative activity of the Constitutional Court of Ukraine is broader than the provision of official interpretation of the norms of the Constitution of Ukraine, it also covers interpretation during the constitutional review of normative acts, public (domestic and international) treaties and during the consideration of constitutional complaints. It was concluded that the interpretive activity of the Constitutional Court of Ukraine is broader than the provision of official interpretation of constitutional norms, it also covers interpretation during the constitutionality check of normative acts, public (domestic and international) treaties (and during the consideration of constitutional complaints). Interpretative acts are an auxiliary means of constitutional and legal policy, they have a derivative, secondary character in relation to normative and legal acts. However, their role in the activity of the Constitutional Court of Ukraine is difficult to overestimate, because they are able to ensure the implementation of high-quality constitutional and legal policy in almost all directions of its influence on legal validity.
