On 7 October 2021, Poland’s Constitutional Tribunal declared Articles 1, 2 and 19 of the Treaty on European Union (TEU) to be partially unconstitutional. While the same Treaty provisions had previously been held compatible (see Case K 18/04) with the Polish Constitution, the composition of the Tribunal itself has since changed dramatically. Its latest decision, issued in response to an application from the Polish Prime Minister, by a panel composed of judges appointed in violation of the established procedure has twisted the wording of both the EU Treaty and the Polish Constitution to suit the government’s power struggle with the Court of Justice of the European Union (CJEU).
