On Thursday, October 7, the Polish constitutional court has decided that when the country joined the EU in 2004, it gave away some rights that should be Polish according to the current interpretation of the Polish constitution. Thus, the Warsaw court has proclaimed that EU law is not above the Polish law, jeopardizing the country’s membership in the union. It does not mean that the country has left the EU yet, but it is another significant step against the EU our north-eastern neighbours have made in the last few months. According to Reuters, disputes over the supremacy of EU law threaten Polish membership in the 27-nation bloc and the stability of the EU itself. The court hearing has been requested by the country’s Prime Minister Mateusz Morawiecki (PiS), after the EU Court of Justice ruled in March that judicial reform promoted by PiS could jeopardize the independence of the country’s judiciary branch of government. The Polish constitutional court has postponed its hearing four times, but now, they finally released their decision. This decision will probably lead to the PiS judicial reforms taking effect in the coming weeks. While the Polish government claims that the reform’s innovations are intended to increase the efficiency of the courts and rid them of the remnants of the past communist regime, critics see them as an effort by PiS politicians to dominate the Polish judiciary. That could be seen as an attempt to destabilize Polish democracy.
