The authors analyse critically the second and third part of the new act on the Constitutional Court which becomes legally binding from the 1 March 2019. Their contribution starts with the consideration on the lack of respect towards the EU law despite the fact that the Constitutional Court is a court who is obliged to submit preliminary ruling questions. There are several specific problems with the interpretation and application of the new act. The most relevant are the decision making by a single judge and the unification of different legal opinions of chambers of three judges of the Constitutional Court. The rest of the interpretative difficulties concern the removal of President and Vice-President of the Constitutional Court.
