The article defines the constitutional and legal status of deputies in relation to the system of the state and municipal positions. The Deputy’s mandate gives a Deputy the opportunity to act as a representative of the people, as well as a representative of the authorities. Accordingly, within the framework of constitutional and legal regulation, it is necessary to analyze and compare the term «position» with such terms as «post», «institution» and «deputy position». In the article, the author used formal-legal and comparative methods, which allowed revealing the differences in these terms, disadvantages in the constitutional legal regulation of the position of Deputy in
the system of the state positions. As a consequence of the analysis, the author comes to the conclusion that the terms «deputy position», «post», «institution» are identical. Also the author identifies the differences in the terms such as « position of Deputy» and «deputy position». As a result of the election, the candidate gets the position of Deputy, which, in its turn, gives him the opportunity to be elected to the deputy position. At the same time it is not legislatively defined the place of a member of the Federation Council, Deputy of the State Duma, Deputy of the Supreme body of the Executive or Legislature of the Federation’s subject in the system of the public
posts. It is necessary to reorganize the internal structure of the legislative authorities to exclude «superior positions» as much as possible, thereby guaranteeing the equality of deputies’ status. However, at the constituent entities, deputies should have the opportunity to influence on the formation of the Executive bodies of the subject of the Russian Federation.
