The only representative international organization bringing together top authorities of the administrative courts in the member states of the European Union is the Assocication of the Counsils of State and Supreme Administrative Jurisdictions of the European Union (ACA-Europe). The Association was created in Stockholm in 1998 but the idea of mutual cooperation between the member states dates back to the 1960s.
After the phase of getting to know the Association (starting in June 2003, the SAC retained the status of an observer), the Court became its full member on 15 June 2004. Thanks to that, the Czech judiciary is now involved in the information exchange system used for the correct application of European Union Law for administrative justice in the Czech Republic. This goal is achieved through participation in expert seminars and colloquia, as well as through access to the database JuriFast, which contains the most important decisions of national courts in Europe in which the highest administrative courts applied EU law.
