Acquis communautaire definition

Acquis communautaire is a French term which means ‘that which the Community has acquired’/‘that which the Community has achieved’. It is the concept of the «acquis communautaire» which permits the EU to maintain its cohesion and to proceed with its objective of deepening, despite its increasing number of members resulting from its successive enlargements. All that has been achieved with respect to European integration up until the date a new member state accedes to the Union, constitutes an indivisible whole, the acquis communautaire, that each new member state is obliged to accept and effectively implement (Çaushi, 2013).
Acquis communautaire means all that the EC/EU has developed, EU Treaties, EU measures, case law and others.
Acquis communautaire means the assets commonly acquired within the EU.
