Null and Void The CJEU Judgment on Poland's Chamber of Extraordinary Control and Public AffairsThe judgment of the Court of Justice of the European Union (CJEU) in the Case C-225/22 from September 4 confirmed that the Chamber of Extraordinary Control and Public Affairs of the Supreme Court in Poland is illegitimate. Second, is a national court prohibited from assessing the lawfulness of the appointment of a judge? No consideration based on the principle of legal certainty or linked to the alleged finality of the judgment prevents an ordinary court from declaring the Chamber’s decisions to be null and void. The saga of the Polish Supreme Court is long and eventful. This, however, was not the only issue with the “reformed” Supreme Court.
