Article (whose first part was published in the previous volume of „Constitutional Law Review”) discusses the problem of constitutional judiciary in post-Soviet states. The author formulates a thesis that constitutional courts in post-Soviet states were supposed to create proper conditions for the primacy of the constitution in the system of normative acts and its direct effect on legal relations taking place in the state. It was expected to guarantee the freedom and rights of an individual. The radiation of the constitution onto the whole of legal, political, economic or social relations occurring in the state promotes the stability of the state’s political system, the protection of values important for the citizens. The author formulates a thesis that to make it happen, proper political conditions are necessary and within them – the control of the new normative acts in the context of their compatibility with the laws of higher legal force, including above all the constitution. This part of the text analyzes the functions of constitutional courts and their political roles in post-Soviet states. Conclusions regarding both parts of the text. First part of this paper was published in „Przegląd Prawa Konstytucyjnego” 2019, no. 2, pp. 137–164.
