The Luxembourg Agreement, which entered into force on 29 January 1966, intended to put an end to an institutional crisis that arose in the European Communities in June 1965, which led France to meet all Council of Ministers meetings was going to boycott. The cause of the crisis was the decision that on January 1, 1966, in a number of policy areas, the requirement for unanimity in decision-making would be replaced by qualified majority voting. France could not live with it. The Luxembourg Agreement (which was not a treaty but a crisis crisis policy) stated that:
The Luxembourg agreement thus actually established the difference between opinion between the Member States. It was an agreement to disagree. However, until July 1, 1987 (with the entry into force of the European Act), it disturbed the decision-making process in the European Communities because all Member States applied: almost always there was a Member State that believed that there were very important interests.
The Treaty of Amsterdam also gained a place in the law of the European Union, as former Article 23 (2) of the Treaty on European Union allows Member States to appeal to the European Council if they consider that a majority decision on the second pillar (Common Foreign and Security Policy) seriously harms the national interest.
