Det er på grundlag af Nice-traktaten, som trådte i kraft den 1. februar 2003, og som bestemte oprettelsen af retsinstanser inden for særlige områder, at Rådet for Den Europæiske Union i 2004 besluttede at oprette EU-Personaleretten, hvis opgave er at afgøre tvister mellem De Europæiske Fællesskaber og disses ansatte.
It was on the basis of the Treaty of Nice, which entered into force on 1 February 2003 and provided for the creation of judicial panels in certain specific areas, that the Council of the European Union decided in 2004 to create the Civil Service Tribunal, whose task it is to rule on disputes between the European Communities and their staff.
