This paper aims to present the arguments formulated in the scientific discussion devoted to the place of the National Assembly in the system of the separation of powers of the Republic of Poland. The author analyzes all statements on this matter, pointing out their strengths and weaknesses, and at the same time putting forward his own counter-arguments and thoughts. At the same time, he emphasizes the possibility of undermining the leading position in the doctrine, which advocates classifying the Assembly as a body of legislative power. In this way, he aims to „air out” views that have been formulated long ago and are therefore very ossified. However, when he undertakes this task, he does not decide anything himself. His purpose is to provoke reflection rather than to issue a categorical decision on the analyzed issue.
