. After the collapse of the USSR, Russia entered a new social transition period, and reform in the fi eld of state structures, including the legal system, began. The judicial power plays an important role in the process of legal reform, and is manifested at several levels of the state, society and the individual. Based on the gradual completion of the theoretical and institutional construction of the mechanism of action of the judicial power of the Russian Federation at the beginning of the transition period, the judicial power is gradually being put into practice, but as society develops, the mechanism of action of the judicial power dynamically develops in accordance with practical requirements, including changes in the system of judicial authorities, changes in the mechanism of judicial proceedings, improvement of the mechanism of control and ensuring the mechanism of judicial power, as well as separation of the power of execution of a sentence from the judicial power.In particular, in the system of judicial authorities, due to excessive pressure on the consideration of cases, the institution of justices of the peace, established during the judicial reform of 1864, was restored in order to ease the burden of the federal court and at the same time achieve a quick resolution of disputes between residents; The complete consolidation of the constitutional judicial system led to the gradual establishment of constitutional (statutory) courts of the subjects of the Russian Federation, which would allow improving the foundations of the constitutional judicial system and the constitutional judiciary in Russia; To address the review of judicial practice in cases related to the resolution of disputes on the protection of intellectual rights, the Intellectual Property Rights Court was established, which expanded the requirements of the judiciary in specialized areas; In order to eliminate various differences between the Supreme Court of the Russian Federation and the Supreme Arbitration Court of the Russian Federation in the interpretation of many laws, the functions of the Supreme Arbitration Court of the Russian Federation were included in the Supreme Court of the Russian Federation.As for the reform of the mechanisms of judicial proceedings, the institution of juries was restored during the judicial reform of 1864 in order to get rid of the institutional abuses associated with the institution of people’s assessors in the USSR; During the period of general social transition and judicial reform in Russia, the change in legal concepts and the requirement of judicial practice led to Russia reviewing and evaluating the institution of judicial precentors and; The principle underlying human rights in the Constitution has brought the role of the judiciary in the fi eld of ensuring and protecting civil rights to a signifi cant one, and the mechanism of administrative action has gradually changed with the adoption and application of the Code of Administrative Procedure of the Russian Federation. In the fi eld of improving the mechanism of control and ensuring the mechanism of judicial power, the judicial power, after judicial reform and institutional construction, achieved a situation of developing independence, a control mechanism was created by a subject consisting of the constitutional court of the Russian Federation, the parliament, the prosecutor’s offi ce, an autonomous body of judges, at the same time, the judicial department under the Supreme Court of the Russian Federation provided for the actions of the judiciary in the transitional period of the Russian Federation.The execution of decisions is the fi nal point of the judicial power, so the issue of the execution of decisions becomes an integral part of the exercise of judicial power in judicial reform, as well as concentrated in civil areas, while a specifi c way of reform is the separation of the power of execution of a sentence from the judicial power. The above will be a manifestation of the institutional transformations of the mechanisms of action of the judiciary to adapt to social development in the transition period. In a special and long process of transition, the judicial power of Russia could achieve useful action, as well as the renewal and transformation of institutions that are formed in practical processes, contributed to the continuous development of the judicial power, while the mechanism of action of the judicial power is continuously being improved.
