The current Constitution of France was adopted on October 4, 1958, and has been amended 17 times, most recently on October 2, 2000. It is typically called the Constitution of the Fifth Republic, and replaced that of the Fourth Republic dating from October 27, 1946. Charles de Gaulle was its main instigator.
It provides for the election of the President and the Parliament, the selection of the Government, and the powers of each and the relations between them. It ensures judicial authority and creates a High Court of Justice, a Constitutional Council, and an Economic and Social Council. It was designed to create a politically strong President.
It enables the ratification of international treaties and those associated with the European Union. It is unclear whether the wording (especially the reserves of reciprocity) are compatible with European Union law.
The Constitution also sets out methods for its own amendment either by referendum or through a Parliamentary process with Presidential consent.
