Poland's Constitutional Tribunal on Thursday ruled against a set of government reforms that would change the functioning of the court. The decision is the latest development in a months-long constitutional crisis that has concerned other EU members and the European Commission. The ruling conservative government says it will not implement the court's decision, despite criticism from civil society groups that it is attempting to control the court's functioning and stack it with sympathetic justices. But in their decision, the judges said they could not rule on a law based on that law itself.
