An error or ultra vires action. The CJEU’s judgement C-448/23 against Poland

The C-448/23 judgment marks a turning point in the relationship between EU member states and the EU. CJEU has entered the area of the state's political system. It ruled not only on the status but also on the competences of the Polish Constitutional Tribunal, limiting its ability to rule on EU law, including deciding on the scope of competences transferred to the Union.
