The first Association was formally constituted in Rome in October 1990. Today, there are 32 associations altogether, representing all the Member States (except Cyprus), plus Croatia, San Marino, Switzerland, and Turkey. AGON, the bulletin of the Associations, was first published in April 1993. It was replaced by eucrim in 2006. The Associations meanwhile function as a network and serve as a forum in the field of European criminal law and the protection of the financial interests of the European Union. They are made up of representatives from the legal and judicial professions (academics and practitioners) as well as other law enforcement agencies (police, inspection departments, etc.). Their mission is based on a series of guiding principles established in the early nineties and highlighting their structure, functions, role, objectives, and activities. Twenty years later, in the light of experience gained and the new environment provided by the Lisbon Treaty, it is appropriate to reflect upon the future role of the Associations in the EU legal space. To this effect, new guidelines were agreed upon among the Associations’ delegates in May 2011 concerning the structure, role, and priorities of the Associations.
