Abstract
Intergovernmental conference (IGC) within the European integration context is a vehicle for institutional change. Based on the majority decision in the Council, the representatives of member states' governments convene to debate proposals for amendments to the founding treaties of the European Union (EU) and make decision on the agreed changes, which are then subject to the ratification process in the member countries according to their constitutional requirements.
This procedure was used for almost all treaty revisions until the Treaty of Lisbon in 2007 changed the rules. Ordinary revision procedure was introduced that assumes a role of the Convention to draft changes to the treaties, while keeping the IGC as a next step in the process.
A simplified revision procedure was introduced for making adjustments to the internal policies and actions of the EU according to the Treaty on the Functioning of the EU, thus replacing the IGC by a unanimous decision of the European Council. This article presents the IGC in historical context of the evolution of the European integration process showing the dynamics of the development of the approaches of relevant actors, both the member states and the EU institutions, to the institution building.
The three cases of the IGCs producing the Merger Treaty of 1965, the Single European Act in 1986, and the Amsterdam Treaty in 1997 represent distinct steps in shaping the perception of the role of the IGC as an institution in the political process within the European Communities and the EU.
