EU governments began an Intergovernmental
conference (IGC) on 4 October 2003 to revise the draft
Constitutional Treaty, adopted by the European Convention on 10
July. Heads of State and Government of the EU-25 failed to
agree on the Council voting system during the IGC session of
12-13 December 2003. The European Council on 17-18 June 2004,
however, brought the IGC to a conclusion.
