Single European Act
The Single European Act (SEA) was the first major revision of the 1957 Treaty of Rome. The Act set the European Community an objective of establishing a single market by 31 December 1992, and codified European Political Cooperation, the forerunner of the European Union's Common Foreign and Security Policy. It was signed at Luxembourg on 17 February 1986, and at The Hague on 28 February 1986. It came into effect on 1 July 1987, under the Delors Commission.
A core element of the SEA was to create a single market within the European Community by 1992, when – it was hoped – the legislative reforms seen necessary would have been completed. To make the objectives possible, the SEA reformed the legislative process both by introducing the cooperation procedure and by extending Qualified Majority Voting to new areas. Measures were also taken to shorten the legislative process.
The SEA was intended to remove barriers and to increase harmonisation and competitiveness among its countries.
