Single European Act

The SEA, which entered into force in July 1987, was the first significant
revision of the Treaty of Rome. The SEA provides the legal and procedural
support for achievement of the single European Market by 1992. The SEA
revised the EEC Treaty and, where not already provided for in the Treaty,
majority decisions were introduced for numerous votes facing the Council of
Ministers, particularly those affecting establishment of the single
European Market and the European financial common market. The role of the
European Parliament was strengthened; decisions on fiscal matters remained
subject to unanimity.
