The Association of European Administrative Judges (AEAJ) was founded in 2000. Its membership comprises:

• National associations, representing administrative judges from the Member States of the European Union and the Council of Europe.
• Individual members, being administrative judges from those countries in which such associations do not exist.

The basis of the Association lies in different initiatives, followed by a meeting in October 1998 at the Academy of European Law (ERA) in Trier, which was devoted to comparative studies on the respective characteristics of administrative law in the respective Member States of the EU. A draft was agreed upon laying out the foundations and aims of the future European Association of Administrative Judges. The aim laid down was to encourage the legal protection of the individual against public violence as well as the lawfulness of administrative actions and thus contribute to strengthening freedom and justice in Europe. In April 1999, draft Statutes for the AEAJ were completed.

On 25 March 2000, the representatives of Germany, Finland, France, Greece, Italy and Austria founded the AEAJ as an international apex organisation under German law.

To date, national associations of administrative judges from 19 European countries have joined the Association. In addition, there are individual members from 15 other European countries.

The AEAJ’s objectives as laid out in art 1(1) of its Statutes.
