Electoral integrity is one of the principle conditions of free political competition among parties and candidates. The electoral processes must be transparent and controllable in all its aspects, so that voters can trust the results of the elections. Representatives of every democratic society must therefore minimize such acts that can lead to questioning the vote and the results of the elections. The main aim of our article is to analyze the various types of electoral malpractice and fraud that occur at the polling stations. Based on quantitative and qualitative research, we have created a set of issues that can be identified in the process of election administration at the level of electoral districts. Part of the article is also a set of proposals which are amendments to legal and subordinate standards and will lead to a higher electoral integrity in the Czech Republic.
