The article analyzes the scientific approaches to the content of the concept of «public administration», «public administration in the activities of the court staff». It is noted that the establishment of the essence of public administration, its features and the actual formulation of the definition of public administration in the court staff, which would fully reflect its legal nature, is the most pressing issue in the light of judicial reform. It is argued that a separate component of building the organizational structure of the court staff is the established practice of organizing activities in each court, taking into account which, the court administration develops and approves standard staffing schedules for each group of courts; on the basis of the maximum number of civil servants and technical staff, the staffing schedules of courts are approved by the heads of their staff and chairmen of courts. It is proved that public administration in the activity of the court staff has not been studied in detail. Doctrinal teachings on the understanding of administration in the judiciary are in many cases opposite and ambiguous. When characterizing public administration in the judicial system, the semantic load is focused on the characteristics of: «organizational support of the courts», «judicial management», «organizational management of courts», administrative relations that exist in the judicial system. Also, the scientific article analyzes the content of the concept of «public administration in the court staff», where we argue that public administration in the court staff is designed primarily for quality organizational support for timely, complete, public and independent work of the court. Therefore, ensuring the functioning of the courts is not only the procedure of justice itself, but first of all organizational support. Efficiency, efficiency, accessibility are a direct impact on the performance of judges directly, and this, accordingly, a positive reputation of the judiciary among the population. Creating the right regulator of the administration in the courts is the key to meeting the requirements of society and ensuring the smooth operation of the judicial system as a whole.
