Taking into account the basic principles of a democratic, rule of law, social state, the key of which is the principle of separation of powers in the state, Ukraine is building a state apparatus. Declaring such a principle in the Constitution of Ukraine and building on it the basis of the functioning of all branches of government have become a prerequisite for the acquisition of judicial branch of power signs of independence and independence. LA Lutz argues that the functioning of the judiciary as an independent is accompanied by its development and the introduction of rulemaking functions. This fact is related to the involvement of the judiciary in the settlement and resolution of national cases. As a result, throughout the years of Ukraine's independence, the courts have recognized the right not only to the application and interpretation of legal rules, but also to their creation. As of today, the law does not formally enshrine the functions of rulemaking, but in legal science there are discussions about the possibility of the existence of case law in the state. The analysis of court decisions suggests that the precedent is not only those of the courts of Ukraine that have a rule of law, but also those that contain appropriate explanations of the content of the rule, or of judgments that contain criteria for the similarity of the application of the rules. The provisions of the basic law − the Law of Ukraine “On Judiciaryand Status of Judges” of 02.06.2016, № 1402-VIII have been analyzed due to the possibility of recognizing judicial precedent as anofficial source of law in accordance with the requirements of the current domestic legislation. In this article, we conducted a detailedanalysis of the peculiarities of the use of case law in the system of domestic justice. Particular attention was paid to updating the system of enforcement of court decisions, including the decisions of the ArmedForces. It is stated that the institute of enforcement of judgments is based on the functioning of the Laws of Ukraine “On EnforcementProceedings” and “On Bodies and Persons who Enforce Enforcement of Judgments and Decisions of Other Bodies”. A separate novelty of judicial reform − the creation of new higher specialized courts as courts of first instance for the considerationof certain categories of cases: the High Court for Intellectual Property and the Supreme Anti-Corruption Court, whose review will bevested in the Armed Forces, has been investigated.
