The relevance of the ideas of Ch. Montesquieu on public administration

Purpose of the study is to analyze the relevance of the political and legal doctrine of Charles Louis de Montesquieu in order to improve public administration. Methods of historical, comparative legal, logical and system analysis were used to analyze the socio-legal reality. It is argued that the theory of separation of powers developed by Ch. Montesquieu still acts as the main mechanism of «transparency» of power. Its advantages and disadvantages are analyzed in comparison with other theories of social structure. The authors give a reasonable assessment of its application in the context of the implementation of the modern approach of building a system of public authorities that meet the needs of citizens performing public administration tasks that affect the socio-legal progressive development of society. The article provides an up-to-date analysis of the theory of separation of powers by Ch. Montesquieu, formulated the problems of political and social structure in the history of the development of states, which are predictive in nature, anticipating problems in the future.
