The Constitutional Council (Conseil Constitutionnel)
The Constitutional Council (Conseil Constitutionnel) is the French constitutional court, established by the 1958 Constitution of the Fifth Republic. Originally conceived as a political body to regulate the boundary between parliamentary legislation and executive regulatory power, it has undergone a remarkable transformation into a genuine constitutional court with broad jurisdiction over fundamental rights. This evolution — from a political regulator to a judicial guardian — represents one of the most significant developments in modern French constitutional law.
Composition and Organisation
The composition of the Constitutional Council is governed by Articles 56 to 63 of the Constitution. The Council comprises nine members appointed for non-renewable nine-year terms. Three members are appointed by the President of the Republic, three by the President of the National Assembly, and three by the President of the Senate. One-third of the membership is renewed every three years, ensuring institutional continuity and staggered political influence over appointments. Former Presidents of the Republic are ex officio life members, though this provision has fallen into disuse as former presidents have increasingly declined to sit.
The President of the Council is appointed by the President of the Republic from among the members (or former presidents sitting ex officio). The President casts the deciding vote in case of a tie. Appointing authorities are not bound by formal eligibility criteria, though in practice they select distinguished jurists, law professors, senior civil servants, and occasionally former politicians. The non-renewable term is a critical independence safeguard: members who cannot be reappointed have no incentive to curry favour with the appointing authority. Members must refrain from partisan political activity during their tenure, and the incompatibility regime prevents simultaneous membership in the government, Parliament, or the European Parliament.
Referral Procedures: A Priori Review
For the first fifty years of its existence, the Council exercised only a priori abstract review of legislation. Under Articles 61 and 61-1 of the Constitution, legislation adopted by Parliament is referred to the Council before promulgation. Originally, only four political authorities could refer bills: the President of the Republic, the Prime Minister, the President of the National Assembly, and the President of the Senate. The 1974 constitutional amendment dramatically expanded access by allowing any group of sixty deputies or sixty senators to refer legislation. This transformed the Council into a genuine forum for opposition challenge, and the number of referrals increased from single digits to dozens annually.
The a priori review procedure operates under tight time constraints: the Council has one month to decide (reduced to eight days when the government declares urgency). The review is abstract — the Council examines the text as adopted, without reference to specific factual circumstances of application. If the Council declares a provision unconstitutional, it cannot be promulgated. The Council may also issue reservations of interpretation (réserves d’interprétation), declaring a provision constitutional only as interpreted in a particular manner. These reservations bind all courts and administrative authorities.
The Question Prioritaire de Constitutionnalité
The 2008 constitutional reform, effective from 1 March 2010, introduced a posteriori constitutional review through the question prioritaire de constitutionnalité (QPC). This mechanism allows any litigant in proceedings before a French court to challenge the constitutionality of an already-enacted statute that infringes fundamental rights guaranteed by the Constitution. The QPC represents the most significant expansion of constitutional justice in France since 1958, aligning France with the European mainstream of individualized constitutional review.
The QPC procedure operates as follows. The litigant raises the constitutional question before the ordinary or administrative court hearing the case. The court conducts a preliminary filter: the question must be serious or novel and must not have been previously decided by the Constitutional Council. The Court of Cassation or the Conseil d’État (depending on the jurisdiction) then conducts a second filter and transmits the question to the Constitutional Council if it meets the statutory criteria. The Council then decides within three months. If the Council declares the provision unconstitutional, it is abrogated either immediately or upon a deferred date set by the Council.
The QPC has dramatically increased the Council’s caseload and its visibility. Hundreds of QPC decisions have been rendered, addressing fundamental rights across criminal law, labour law, tax law, social security, and immigration. The procedure has enabled individuals to challenge laws that infringe their constitutional rights years after enactment, fundamentally changing the dynamics of French constitutional litigation.
The Scope of Constitutional Review
The Council’s review extends beyond the text of the 1958 Constitution. Since its landmark Freedom of Association decision of 16 July 1971, the Council has applied the bloc de constitutionnalité — a set of constitutional norms including the Constitution itself, the Declaration of the Rights of Man and of the Citizen (1789), the Preamble of the 1946 Constitution (which incorporates fundamental principles recognized by the laws of the Republic), and the Charter for the Environment (2005). The Council also recognizes constitutional objectives (objectifs de valeur constitutionnelle) such as the clarity of the law, the protection of public order, and the accessibility of legislation.
The Council’s decisions are concise, syllogistic, and devoid of dissenting opinions. Unlike the German Federal Constitutional Court or the U.S. Supreme Court, the Council does not publish separate opinions. This reflects the French conception of constitutional justice as a unified, impersonal expression of the law. The absence of dissents has been criticized as reducing transparency, but it remains a distinctive feature of French constitutional adjudication.
Evolution from Political Body to Constitutional Court
The Council’s transformation from a political regulator to a constitutional court occurred through three critical developments. The first was the 1971 decision extending the bloc de constitutionnalité to include fundamental rights, providing substantive standards for review. The second was the 1974 amendment expanding referral rights to parliamentary minorities, turning the Council into an opposition forum. The third was the 2008 QPC reform, making the Council accessible to ordinary citizens. Each development incrementally judicialized the Council’s functioning while reducing its original political character.
Contemporary scholarship generally classifies the Council as a constitutional court, though its hybrid origins continue to shape its identity. It combines features of the Kelsenian centralized model of constitutional review (exclusive jurisdiction, abstract review) with elements of the diffuse model (concrete review through the QPC). The Council’s composition — mixing jurists with former politicians — and its collegial, non-dissenting decision-making style distinguish it from other European constitutional courts.
Landmark Decisions
Among the Council’s most significant decisions are: the 1971 Freedom of Association decision (71-44 DC), which incorporated fundamental rights into the constitutional block; the 1981 Nationalization decision (81-132 DC), which established the Council’s review of economic legislation; the 1993 Immigration decision (93-325 DC), applying proportionality review to restrictions on fundamental rights; the 1999 Treaty of Amsterdam decision (97-394 DC), addressing the relationship between European law and the Constitution; and numerous QPC decisions including the 2010 Garde à Vue decision (2010-14/22 QPC), which required fundamental reforms to police custody procedures. These decisions demonstrate the Council’s centrality to French public law and its continuing evolution as a guardian of constitutional rights.
