The article focuses on the approaches towards understanding the concept of the electoral system, which may be the subject of research outside the field of law. The author distinguishes different opinions of foreign and Ukrainian scholars on the term “electoral system”, in particular, narrow and broad interpretation. The author analyzes the elements which inherently fill and reveal the concept of the electoral system. The article provides an overview of scientific research and concepts that study electoral systems, including the works of prominent Ukrainian and foreign scholars, as well as documents of international organizations and institutions. The author analyzes different approaches to the interpretation of the concept of “electoral system”, its legal nature and key elements that have a significant impact on the formation of elected bodies and the organization of electoral processes, and further establishment of democratic principles. The author presents various positions on the elements through which the concept of the electoral system is revealed, such as the electoral formula, electoral district, method of expressing the will of voters, structure of the ballot and the process of filling it out, method of voting, etc. The author shows the importance of these elements and how they are reflected in the definition and modification of different types of electoral systems. The author emphasizes the need for further study of the concept of an electoral system and its systemforming elements, which allow constructing an appropriate type of electoral system, in the context of Ukraine’s experience in organizing and conducting elections. This will have a positive impact on the process of improving the electoral systems used in the formation of elected bodies at the legislative level, which will consequently contribute to ensuring greater transparency of a number of electoral procedures, obtaining fair results and minimizing the risks of their distortion. The author outlines the problem of periodic unsystematic changes in electoral systems in the formation of elected bodies in Ukraine, which in turn generates negative trends in the decline of citizens’ electoral culture, trust in the results of voters’ expression of will and unpredictable consequences in the socio-political context.
