Single European Act (SEA)
The first Intergovernmental Conference opened under Italy's chairmanship on 9 September 1985, culminating in the adoption of the Single European Acton 28 February 1986 in Brussels.
The Single European Act brought amendments to the Treaties establishing the European Communities and established European political cooperation. Once the Single European Act (SEA) entered into force, the title 'European Parliament'(which the Assembly had used since 1962) was made official. The SEA also increased the EP's legislative powers with the introduction of the cooperation and assent procedures.
