Abstract
The article analyses new regulations for controlling certain institutions. They introduce significant restrictions on mergers and acquisitions, including the requirement to notify the President of the Competition and Consumer Protection Office about the intended transaction. The changes have been urged by the need to prevent the consequences of the COVID-19 pandemic and adjust Polish laws to the screening regulation. However, the adopted solutions arouse some major doubts as to their compliance with both the Polish Constitution and EU law. This concerns the excessively extensive objective and subjective scope of protection as well as the conditions allowing to challenge the transaction.
