Socio­legal situation of Poland is now a lot different from the one before 2004. Membership of our country to an integrative organization with such an advanced character as the European Union causes that it is necessary to take a wider look at the issue of functioning of the political system patterns, as well as, as a consequence, at entities and methods which may be taken into account during public decision making. Here one of the most interesting issues, and as it seems still least learned aspects of the EU governance is proceeding participation of the judicial sector of the EU within political life of the member states. Aim of the author is to verify a research assumption that the CJ jurisdiction has a serious social dimension, noticeable also for Polish nonpublic actors. According to the principle of the CJ judicature, today named as quasiprecedent, each nonpublic body may point to previous judgements of the Court each time it assumes that it might have positive effects. But when we take into account how large that source is today possibility of such situation is high.

The fact that our country belongs to the European Union, an integration organization of such an advanced character and multilevel construction, necessitates deeper insight into the issue of our political system. As Poland is a new member state, it is currently “learning how to participate” in the integration process, which refers both to its authorities and society. However, it is not an easy task because the Union is the most structurally advanced international organisation in the world, with unique construction and methods of operation, which develops the framework for legal mechanisms finding no direct analogy in national systems. One of these mechanisms is the fact that judicature of an international court, i.e. the Court of Justice, is constantly used for executing current internal tasks of the state. It seems justifiable to note that the Court’s judicature is becoming a factor which may and should be taken into consideration in the policy decision-making process in the Republic of Poland. Thus, we should widely inform about the consequences of the fact that the Court of Justice has become an immanent part of the Polish system.
