The Conseil d'État is the highest administrative court in France with final jurisdiction over cases involving misuse of administrative power. Executive action is subject to its review, as is the conduct of the bureaucracy, and it may make recommendations on administrative reform. It must also be consulted in advance concerning certain types of legislation initiated by government for submission to parliament, while the government may seek advisory opinions. Individual citizens have access to the Conseil d'État, ensuring a degree of personal accountability for administrative acts and providing a check on the use or abuse of discretionary powers. Acts may be annulled where the administration has exceeded its powers or has not complied with formal procedures. Under the Fifth Republic the Conseil d'État has consciously acted to extend its judicial control to keep pace with the expansion of executive power: a reversal of its role under previous republics where it was more concerned to strengthen a weak executive. The Conseil d'État is among the leading grands corps, with its members serving the state at all levels and in the highest offices.
