Challenges in the area of the sources of law in contemporary Polish constitutional law

The aim of the paper is conducting the analysis of the issue of new challenges in the area of the sources of law in contemporary Polish constitutional law. The above-mentioned analysis is currently particularly important from the point of view of Poland and its systemic and political practice.
In this regard, it is necessary, among other things, to consider whether there is a need in Poland for systemic changes within the institution of acts of executive organs with the effect of a statute (e.g. in order to implement the EU law)? At the same time, it is worth to consider the introduction into the Polish law of the organic law.
Moreover, it is worth to consider if the Polish legislator – parallel to the systemic changes within the area of the sources of law – should carry out systemic reform the legislative process aiming at its optimization as well as to improve the system of governance and the system of mutual relations between the parliament, the government and the president.
