Constitutional court plays crucial role in the process of illiberal system consolidation. In the analysis, the Polish Constitutional Tribunal (CT) is used as an exemplification of such a role. The Tribunal has been taken over by newly established majority in 2015 general election. After the capture, the CT started to confirm unconstitutional actions of the unconstrained majority. Additionally, the CT delivers a new interpretation of the constitution. Such new interpretation enables transformation of the system towards illiberal democracy. In result, constitutional judges become servants of political will rather than a constrain on the Parliament and a guarantor of human rights. Such a change of the Constitutional Tribunal's goal hinders systemic re-transformation and provides stabilization of illiberal democracy. Is the CT only the servant or more a politically active actor?
