A Polish judge critical of government court reforms was protected Tuesday from prosecutors who were seeking to charge him with exceeding his mandate. Poland's judicial system has become a battleground for independent judges and the ruling rightwing PiS party seeking to impose reforms in the courts -- which critics say are aimed at muzzling dissent. Warsaw district court Judge Igor Tuleya, 49, faced disciplinary action for allowing media into a hearing on whether the Law and Justice (PiS) party had violated rules during a 2016 parliamentary vote. His supporters believe the prosecutor's office targeted Tuleya in reprisal for his vocal criticism of judicial changes introduced by the PiS since it took over in 2015. The Supreme Court disciplinary chamber that ruled in Tuleya's favour is one such change and he rejected its authority, refusing to attend the session. "I don't care that this decision doesn't fulfil the prosecution's request. It's an illegal tribunal and an illegal ruling," Tuleya told reporters. Other Polish judges expressed support for his position, and rallies backing him took place in several parts of the country on Monday. The European Court of Justice (ECJ) ordered Poland in April to suspend the chamber pending a final ruling on questions regarding its independence. On Monday, the European Commission said it had written to Polish authorities regarding their response to the ECJ ruling, noting that they had not fully complied with the ECJ order. Commission spokesman Christian Wigand said it has asked Warsaw to clarify the issue by June 24. The PiS says judical reforms are needed to tackle corruption but opponents charge they threaten the rule of law. The European Commission has launched four infringement procedures against PiS-authored judicial reforms, which it says test democracy by undermining judicial independence. The unprecedented proceedings could result in the suspension of Poland's EU voting rights. sw-amj/wai
