General Assembly of the European Network of Councils for the Judiciary (ENCJ) gathered in Lisbon between 30 May-1 June 2018 and 6th part of its decleration is about Turkish judiciary as follows:

“6. The situation in Turkey is also very disturbing. In December 2016 the ENCJ suspended the observer status of the High Council for Judges and Prosecutors for non-compliance with European Standards and the ENCJ Statutes. The ENCJ has more recently learned with great regret that one of the former members of the High Council for Judges and Prosecutors has passed away in detention. The ENCJ wishes to express, once again, its solidarity with the dismissed judges and prosecutors of Turkey and calls upon the relevant Turkish authorities to ensure speedy, open, fair and impartial judicial process for the detained judges and prosecutors. The first reports of the trials against judges and prosecutors give little reason to believe that justice is being valued.”
