Swearing-in Ceremony of the Members of the Court of Justice of the European Communities

On October 7, 1958, the members of the Court of Justice of the European Communities, under the presidency of Andreas Matthias Donner, President of the Court of Justice of the European Communities, held their first public session and were sworn in at the Cercle municipal de la Ville de Luxembourg. From that day, the Court of Justice of the European Communities began to function as a “single Court” for the three European Communities, namely the European Coal and Steel Community (ECSC), the European Atomic Energy Community (EAEC), and the European Economic Community (EEC). It was established in 1952 as the Court of Justice of the ECSC; however, with the entry into force of the Treaties of Rome, which established the EAEC and the EEC (signed on March 25, 1957, and entered into force on January 1, 1958), the Court became the unified judicial body for all three Communities on October 7, 1958. The Court remains to this day the supreme Court of the EU responsible for the coherence and unity of the Community legal order.
