ACA Europe – Association of the Councils of State and Supreme Administrative Jurisdictions of the European Union

Aims and Methods

ACA Europe aims to promote the sharing of opinions and experience between its members. The association focuses on the jurisdiction, work and methods of the courts, as well as on European law. ACA Europe holds seminars and conducts studies for this purpose. Judges have the opportunity to complete a two-week guest residency at another European court. Besides a web-based exchange forum, it also maintains JuriFast, a publicly accessible database containing rulings by its members. The working languages are English and French.


The members of ACA Europe are the supreme administrative courts in all member states of the European Union, Norway and Switzerland, as well as the Court of Justice of the European Union. Montenegro, Serbia and Turkey have observer status.


The Presidency of ACA Europe alternates between the members of ACA Europe every two years. Piet Hein Donner, Vice President of the Dutch Council of State, is currently President of ACA Europe. The President of the Federal Administrative Court, Prof. Dr. Dr. h.c. Klaus Rennert, is scheduled to take charge of the Presidency of ACA Europe from 2018. Six seminars - three of which will be held in Germany -, are planned for the two years of German presidency.
