Arrêt Arrighi (1936): Theory of Loi-Écran

The Arrêt Arrighi, decided by the Conseil d’État on 6 November 1936, is the foundational decision on the théorie de la loi-écran (statute-screen theory). The case established that administrative courts could not review the constitutionality of a statute or of administrative acts that merely implement a statute. This doctrine defined the relationship between statute and constitution in French law before the establishment of the Constitutional Council in 1958 and remains a significant historical precedent for understanding the evolution of French constitutional review.

Facts

The plaintiff, Arrighi, challenged a decree adopted by the French government pursuant to the law of 8 June 1936, which granted the government full powers to implement the Matignon Agreements through legislative decrees (décrets-lois). The plaintiff argued that the decree exceeded the authority delegated by Parliament. The Matignon Agreements, negotiated by the Popular Front government of Léon Blum, introduced major social reforms including the 40-hour work week, paid vacation, and collective bargaining rights. The case arose during a period of intense political and social transformation.

The law of 8 June 1936 was itself a loi de pleins pouvoirs (full powers law), a legislative technique by which Parliament delegated broad authority to the government to issue decrees having the force of law. This technique was frequently used during the Third and Fourth Republics to address urgent economic and social matters. Arrighi contended that the government’s decree exceeded the scope of the delegation and violated constitutional principles.

Legal Issue

The central question was whether the Conseil d’État could review the constitutionality of a decree issued pursuant to a statute, or more fundamentally, whether it could review the constitutionality of the statute itself. French constitutional law in 1936 did not provide for any form of judicial review of legislation. The loi (statute) was considered the supreme expression of the general will (volonté générale), and no court had the power to declare it unconstitutional. The case presented the Conseil d’État with an opportunity to establish constitutional review.

Decision

The Conseil d’État held that it could not review the decree because the statute that authorized it stood as an écran (screen) between the decree and the constitution. As long as the decree merely implemented the statute, the court could not examine its constitutionality without indirectly reviewing the statute itself. Since the Conseil d’État had no jurisdiction to review statutes, the challenge failed. The decision established that a statute shields implementing administrative acts from constitutional challenge.

The Conseil reasoned that the French legal system did not confer on any court the power to refuse to apply a statute on constitutional grounds. The separation of powers, as understood in French tradition, prohibited courts from sitting in judgment on the legislature. This position reflected the revolutionary legacy of the Law of 16-24 August 1790 and the conception of prééminence de la loi (supremacy of statute) that characterised French public law until 1958.

The Loi-Écran Doctrine

The théorie de la loi-écran operates as follows: when an administrative act is challenged before an administrative court, and the act merely applies a statute, the court must examine the legality of the administrative act against the statute, not against the constitution. If the statute is clear and the administrative act conforms to it, the court cannot invalidate the act on constitutional grounds, because doing so would require the court to disapply the statute — a power it does not possess.

The doctrine had two corollaries. First, if the administrative act was not mandated by statute but was adopted in the exercise of the government’s independent regulatory power (pouvoir réglementaire autonome), the Conseil d’État could review it directly against constitutional principles. Second, if the statute was unclear or ambiguous, the Conseil d’État could interpret it in light of constitutional principles without directly reviewing its validity. These exceptions created important but limited avenues for constitutional argument in administrative cases.

Evolution and Decline

The loi-écran doctrine dominated French administrative law for over fifty years. However, three developments progressively undermined it. First, the 1958 Constitution established the Constitutional Council (Conseil constitutionnel) with jurisdiction over certain categories of legislative acts, though initially only through a priori review. Second, the 1971 Associations decision expanded the bloc de constitutionnalité to include the preamble of the 1958 Constitution and the Declaration of the Rights of Man and of the Citizen, creating a richer set of constitutional norms. Third, and most decisively, European integration and the ratification of the European Convention on Human Rights created external standards against which French courts could review even unambiguous statutes.

The Arrêt Nicolo (1989) dealt a severe blow to the doctrine by accepting that EU law could override subsequent French statutes. The Conseil d’État held that EU treaties took precedence over French statutes, even those enacted after the treaties. This decision effectively pierced the loi-écran for EU law purposes. Subsequently, the Conseil d’État accepted that the European Convention on Human Rights could also serve as a standard for reviewing statutes.

The constitutional reform of 2008 introduced the question prioritaire de constitutionnalité (QPC), which allows litigants to challenge the constitutionality of already-promulgated statutes before any court. Under the QPC procedure, if a statute appears to violate constitutional rights, the matter is referred to the Constitutional Council for a binding determination. This mechanism has largely rendered the loi-écran doctrine obsolete, though it remains technically applicable to constitutional arguments that fall outside the QPC framework.

Legacy

Arrêt Arrighi is remembered primarily for articulating the loi-écran theory that defined the limits of French judicial review for over half a century. The case illustrates the French conception of the separation of powers, under which courts traditionally deferred to parliamentary sovereignty. The gradual erosion of this doctrine — first through the establishment of the Constitutional Council, then through European legal integration, and finally through the QPC — represents one of the most significant transformations in modern French public law.

The decision also reflects the broader tension between democratic legitimacy and constitutional supremacy that characterises constitutional law in many jurisdictions. The French experience with the loi-écran doctrine offers a cautionary tale about the limits of parliamentary sovereignty when fundamental rights are at stake, and it demonstrates the importance of establishing effective mechanisms for constitutional review.
