Treaty of Nice

The Treaty of Nice was signed on 26 February 2001. The main focus of the Nice Treaty is the reform of the EU's internal operating mechanisms in order to allow an enlarged Union of around 27 members to operate efficiently. During the longest summit ever in EU history, the Heads of State of Government of the 15 Member States finally reached agreement on the size and composition of the Commission, the reweighting of votes in the Council, quelified-majority voting, the distribution of seats in the European Parliament and enhanced cooperation. The Treaty was also published in the Official Journal of the European Communities (OJ C 80 10.3.2001).
