The self-proclaimed head of Poland’s Constitutional Court, Anna Korwin-Piotrowska, is summoning Polish judges to attempt to resolve the crisis at the Constitutional Tribunal

Judge Anna Korwin-Piotrowska, who claims to have temporarily taken over the leadership of Poland’s Constitutional Tribunal after the institution’s president and vice president were suspended, has called a General Assembly of Judges for Tuesday. The meeting is taking place against the backdrop of a deep institutional crisis and disputes over control of the court.

Korwin-Piotrowska, backed by Prime Minister Donald Tusk’s government, told the judges that they are obliged to attend the meeting. She could seek measures against judges from the opposing camp, including lifting their immunity or terminating their mandates.

The conflict pits two groups of judges against each other: one appointed during the rule of the conservative Law and Justice party, supported by President Karol Nawrocki, and another associated with the current pro-European majority led by Tusk. Nawrocki does not recognize the suspension of the tribunal’s leadership and has refused to receive the oaths of five judges appointed by the new majority.

The crisis escalated on Friday, when police cordoned off the court’s headquarters, the justice minister called for the tribunal president’s immunity to be lifted, and Korwin-Piotrowska proclaimed herself acting president. The government described the action as a restoration of the rule of law, while the opposition denounced it as a coup. The European Commission called on Nawrocki to approve the appointment of the judges.
