The study deals with the problem of legal acts of election commissions from the position of established classification of legal acts, determining the task of finding a new system of organization of electoral process and its formal expression on the basis of the principle of separation of powers. It is noted that legal acts of election commissions are defined by the legislator ra-ther as interpretative acts, but legal validity demonstrates the abundance of legal acts of different nature. To understand what exactly is the task set for the research. According to the author’s point of view, it is necessary to ana-lyze and classify the legal acts of election commissions not only depending on the presence of legal regulations, but also in the terms of their legal con-tent aimed at the implementation and protection of the electoral rights of cit-izens, understood as the measure of freedom, justice, equality in the field of electoral relations on the one hand, and the organization and preparation of elections, on the other. The conclusion is made that all these dictates the need to organize electoral process on the basis of the principle of separation of powers, which can have considerable theoretical and practical significance. The results of the research may have the potential to overcome the negative phenomena that accompany the mechanism of electoral representative de-mocracy in recent years.
