A conference of government representatives of the member states of the EU. It is convened to deliberate on amendments to the Treaty of Rome. There is no time limit to IGCs, but they usually take between one and two years in order to reach a viable consensus, since every change to the Treaty of Rome can only come into effect if agreed by consensus and ratified by every member state. The most important IGCs since the Treaty of Rome prepared the Single European Act (1985–6), the Maastricht Treaty (1991–2), the Treaty of Amsterdam (1996–7) the Treaty of Nice (1999–2000), and the Treaty establishing a Constitution for Europe (2003–4).
