The EEA Agreement guarantees the free movement of persons, goods, services and capital, provides fair competition and abolishes discrimination on grounds of nationality in all 30 EEA States - the 27 EU States and 3 of the EFTA States. The successful operation of the EEA depends upon a two-pillar system of supervision involving the EC Commission and the EFTA Surveillance Authority. A two-pillar structure has also been established in respect of judicial control; the EFTA Court operates in parallel to the Court of Justice of the European Communities. The EFTA Court, which celebrates its 20th anniversary in 2014, has jurisdiction with regard to EFTA States which are parties to the EEA Agreement (at present Iceland, Liechtenstein and Norway). The jurisdiction of the EFTA Court mainly corresponds to the jurisdiction of the Court of Justice of the European Communities over EC States. It consists of three Judges, one nominated by each of the EFTA States party to the EEA Agreement. The essays in this collection, assembled to celebrate the 20 year landmark, and written by members of the Court and external experts, review the successes and shortcomings of the Court, its interface with EU law, and the prospects for its future development.
