The dynamic development of the COVID-19 epidemic hampered the functioning of administrative bodies, especially those consisting of many people. In 2020, many countries had to solve the problem of how to adapt their laws to the requirements of the pandemic, while maintaining the safety requirements of members of parliaments. The introduced solutions included suspending the proceedings, modifying the quorum, or changing the voting method. Few countries (including Poland) have fully used the available technologies, deciding to allow parliaments to hold and vote remotely. The conducted analysis is aimed at identifying the systemic solutions that made it possible to introduce such solutions, as well as at determining what modifications of the legal system were necessary to establish innovative solutions.
