On 29 May 2018, Gerald Knaus and Piotr Buras, both Europe's Futures fellows, published a joint report on the rule of law in Poland. Rarely has anything its authors have written had as immediate an impact as this. They made a concrete recommendation: that the European Commission take Poland to the Court of Justice of the European Union (CJEU) to challenge its Law on the Supreme Court, which violated the core principles of the legal order of the European Union. On 2 July 2018, the European Commission started the procedure which led to Poland being taken to the CJEU in September of that year. The court issued an interim decision to stop implementation of the law. The Polish government withdrew its changes. It was a victory for the rule of law.
