The COVID-19 pandemic occurred in Poland during the campaign before the presidential election scheduled for May 10. This non-military threat changed the election campaign’s dynamics, leading to an unprecedented failure to hold elections and postponing them. Around the changes in the election procedure, many constitutionalists and political scientists voiced their inconsistency with the law and the provisions of the Constitutional Tribunal. Both the proposed provisions and the manner of their organization raised objections. The article classifies these changes as manifestations of democratic backsliding, weakening democratic institutions and leading to a decline in the quality of democracy. The research goal is to analyze the records in the selected source material and relate them to the selected theoretical category (democratic backsliding). In the course of the research, the following hypothesis is verified: in the face of the COVID-19 epidemic in Poland, attempts by the ruling elite to change the provisions related to organizing the presidential elections scheduled for May 10 are an example of democratic backsliding, which, by weakening democratic institutions, has threatened the constitutional provisions and the essence of the democratic system.
