The COVID-19 pandemic is one of the major problems facing the majority of Western societies in the first half of 2020. The essence of the threat to public health does not differ from those associated with the spread of other infectious diseases. National responses to the increase in SARS-COV-2 infection were various. In the case of the Republic of Poland, the legislator reacted, despite the fact that provisions for counteracting epidemics were already in force. The assessment of the advisability of adopting new normative solutions in the context of this circumstance is one of the aims of this study. The second aim is the analysis of selected provisions intended to counteract the COVID-19 epidemic from the point of view of the principles of correct legislation as a key criterion for the effectiveness of changing the legal status. The third aim is to assess the regulations introduced into the Polish normative order in March 2020 in the context of constitutional values. It should be remembered that extraordinary events often evoke strong emotions. Fear of a sudden and not yet fully understood threat induces society to accept far-reaching restrictions of human and civil rights and freedoms. That is why it is particularly important to carry out the objective verification of constitutionality of the provisions of a legal act issued in such conditions.
