Decision-Making at the Summit
Various provisions of the Treaty on European Union (“TEU”) and of the EC Treaty specifically require action to be taken, at the definitive stage or at some preparatory or intermediate stage of decision-making, by the European Council, or by the Council of the European Union meeting in the composition of Heads of State or Government (“the HSG Council”); and there is one instance of an appointing power exercisable by an intergovernmental conference at the level of Heads of State or Government (“an HSG Conference”). Reserving a role for the political leaders of the Union in the adoption of particular decisions was an innovation of the TEU, more especially in the Title of the EC Treaty on economic and monetary policy, and further instances have been added by the Treaty of Amsterdam (“TA”) and the Treaty of Nice (“TN”).
