The reform of the Polish judicial system, promoted and approved in December 2019 at the request of PiS, violates EU law. This was said at the time by numerous associations, all the opposition parties and the European Commission.

The European Commission appealed, considering that this "amending law" gave the Disciplinary Chamber of the Supreme Court, whose independence and impartiality were clearly not recognized, powers to rule on the status of judges and the exercise of judicial functions. The ruling indicates that Poles have no right to information about whether the judges trying their cases are political activists.
