Abstract: The research subject is the public law concept reflected in the works of Russian jurist-researchers of the 19th century – Vasilii Nikolaevich Leshkkov (1810 – 1881) and Mikhail Mikhailovich Shpilevsky (1837 – 1883). The fundamental provision of the concept is the thesis that society is the key independent subject of public administration; private individuals as members of social associations obtain wider opportunities to realize their interests. The research subject is the ideas of V.N. Leshkov and M.M. Shpilevsky about objects, subjects and the subject-matter of public law; the jurist-researchers’ estimation of the public law concept of the 19th century. The research methodology is based on general scientific (historical, system, functional) and specific (formal-legal, historical-legal and comparative-legal) research methods. The author uses the methods of interpretation of legal ideas and statutory acts. The author characterizes the public law concept reflected in the theoretical heritage of V.N. Leshkov and M.M. Shpilevsky, which hasn’t been studied thoroughly enough so far. Within the public law concept society if considered as the key subject of administration; families, communities, classes and various interstate associations and everything created by the public – as the objects of public law. The author estimates Leshkov’s conclusions that public law reflects the process of emergence and development of social regulators; allows defining the specificity of public regulation of social relations within particular historical epoch, helps study the evolution of the legal system of any state. Therefore, when making important managerial decisions, it is necessary to take into account the experience of development of the public law sphere in a certain state.
