The study used a database of secondary legislation covering 1990-2019. The final empirical data consists of 5,427 documents, including 1,272 directives and 4,155 regulations. The research empirically confirmed the increase in the frequency of procedures application that envisage a more active participation of the European Parliament in the legislative process. At the same time, the authorreveals that a significant part of secondary legislation is still adopted by the Council without the EPinvolvement. An important difference in the use of adaptation procedures of directives and regulations has been identified; working hypotheses about the reasons for such differences have been formulated.
