The article reveals the peculiarities of the observance and implementation of the principle of the rule of law in the judicial practice of Ukraine. It was established that the implementation of the rule of law is regulated by the Resolution of the Plenum of the Supreme Court of Ukraine «On a Court Decision in a Civil Case», the Law of Ukraine «On the Judiciary and the Status of Judges» and the Constitution of Ukraine. It has been established that the principle of the rule of law is one of the main principles of a democratic society. It has been established that the problem of observance of the principle of the rule of law in the judicial practice of Ukraine is of a complex nature, and it can be solved only through the implementation of a comprehensive judicial and legal reform. It has been established that in the context of observing the rule of law in Ukraine, the experience of the European Court of Human Rights should be implemented. It has been established that the implementation of the principle of the rule of law occurs through the implementation of the principle of legal certainty, the principle of juridical certainty, the principle of justice, the principle of equality, the principle of clarity and unambiguity of the legal norm, the principle of proportionality, the principle of predictability. It has been proven that in the context of the administration of justice, the court must comply with the principle of the rule of law, as well as ensure the right of everyone to a fair trial, to ensure respect for everyone, as well as other rights and freedoms defined by legislative and regulatory documents. It has been established that one of the main principles for the implementation of the principle of the rule of law is the implementation of changes in legislation in order to establish an appropriate transitional period (that is, a reasonable period between the date of the official promulgation of the law and the date of entry into force of the law). It was determined that the implementation of the principle of the rule of law indicates the limited nature of public authorities in actions, primarily those regulated by law, and the main goal of the principle of the rule of law is to limit state power over everyone, as a result of which the rights of everyone should be properly ensured against arbitrary (and at the same time inappropriate) interference of the state or public authorities, in particular, in the relevant spheres of life of everyone. It is noted that the prospects for further research in this direction are the study of the legal foundations of other principles that guide the activities of the judicial authorities of Ukraine.
