French Legal Positivism
The Exegetical School and the Origins of French Positivism
French legal positivism emerged from the École de l’Exégèse, which dominated French legal thought throughout the nineteenth century. The exegetes, including Charles Demolombe, Aubry and Rau, and Charles Toullier, approached the Code civil of 1804 as a complete and self-sufficient legal system requiring no supplementation by morality, custom, or judicial creativity.
The exegetical method held that the sole task of the jurist was to discover and apply the will of the legislator as expressed in the statutory text. Demolombe’s famous dictum — “la loi est la loi” (the law is the law) — captured the positivist conviction that legal validity depends solely on the formal source of the norm, not its content.
The exegetes developed a distinctive methodology. Interpretation was limited to grammatical and logical analysis of statutory language. The travaux préparatoires (legislative history) were consulted to confirm the legislator’s intention but not to supplement or qualify the text. Gaps in the law were to be filled by recourse to analogy within the Code, not by reference to external principles of justice.
Carré de Malberg and State Positivism
Raymond Carré de Malberg (1861–1935) is the most significant figure in French legal positivism. His two principal works, La contribution à la théorie générale de l’État (1920) and La loi, expression de la volonté générale (1931), developed a theory of law grounded in the sovereignty of the state.
Carré de Malberg rejected the natural law tradition and the German historical school, arguing that law is a product of state will and that legal validity derives from the sovereign’s command. The state, for Carré de Malberg, possesses original and unlimited power to create law, limited only by the procedural rules of the constitution.
The influence of Carré de Malberg on French public law has been profound. His concept of souveraineté nationale (national sovereignty) provided the theoretical foundation for the Third Republic’s legal system and informed the drafting of the Constitution of 1958. The Conseil constitutionnel in Décision n° 71-44 DC (1971) implicitly drew on Carré de Malberg’s framework in identifying the principes fondamentaux reconnus par les lois de la République as constitutional norms.
Carré de Malberg’s positivism was not absolute. He recognised that in certain circumstances — particularly in the interpretation of administrative law — the judge must exercise creative functions. However, he maintained that such creativity is always subject to the ultimate sovereignty of the legislator and can be overridden by explicit statutory provision.
Esmein and the Constitutional Tradition
Adhémar Esmein (1848–1913) was the founding figure of French constitutional law scholarship and a proponent of legal positivism in the public law domain. His Éléments de droit constitutionnel français et comparé (1896) established the methodological foundations of French constitutional law.
Esmein’s positivism was more moderate than Carré de Malberg’s. He accepted that constitutional law is grounded in political reality and that the interpretation of constitutional texts must take account of historical context and institutional practice. However, Esmein insisted that constitutional interpretation must be guided by legal, not political, criteria and that the constitutional judge applies existing rules rather than creating new norms.
Esmein’s influence is evident in the methodology of the Conseil constitutionnel. The Council’s early decisions were notably positivist in character, grounding constitutional review in the text of the Constitution and the Déclaration des droits de l’homme et du citoyen of 1789, rather than in extratextual principles.
Les Faiseurs de Systèmes (The System-Builders)
The late nineteenth and early twentieth centuries saw the emergence of les faiseurs de systèmes (system-builders) in French legal science. These jurists, including François Gény, Raymond Saleilles, and Paul Roubier, sought to systematise French law into a coherent doctrinal structure.
The system-builders departed from the strict exegetical method. Gény, in his Science et technique en droit privé positif (1914), argued that the jurist must go beyond the text of the law to identify the underlying principles and techniques that give the legal system its coherence. Gény introduced the concept of libre recherche scientifique (free scientific research) as a method for filling gaps in the law.
Saleilles, the leading figure of the École de la libre recherche, advocated for a functional approach to legal interpretation. In his De la déclaration de volonté (1901), Saleilles argued that the judge must interpret legal texts in light of their social purpose and the practical consequences of alternative interpretations.
Roubier developed a systematic theory of théorie générale du droit (general theory of law) that integrated the insights of the system-builders while maintaining a positivist foundation. His Théorie générale du droit (1946) identified the concepts of subjective right, legal personality, and legal act as the fundamental building blocks of the legal system.
Conceptualism (Conceptualisme Juridique)
French legal conceptualism, closely related to positivism, treats legal concepts as autonomous categories with their own logical structure. The conceptualist approach, associated with the work of Jean Dabin and Charles Eisenmann, holds that legal reasoning consists of the logical manipulation of concepts derived from the legal system.
Conceptualism reached its fullest development in the private law doctrine of the École de la conception. The conceptualists argued that legal concepts — property, contract, tort, obligation — have an inherent logic that determines their application to new situations. Legal rules are deductions from these concepts, not policy choices.
The Cour de cassation’s judgments reflect conceptualist methodology. The court’s reasoning typically proceeds from abstract concepts to concrete conclusions, without explicit consideration of policy or consequences. In Cass. civ. 1re, 28 janvier 2020, the court resolved a novel question of contract law by reasoning from the concept of cause (consideration) without discussing the economic implications of its ruling.
Conceptualism has been criticised for its formalism and its detachment from social reality. The realist critique, associated with the American legal realists and the French sociologie juridique, argues that conceptualist reasoning masks the policy choices that judges inevitably make.
Realist Critique and the Réaction Contre le Conceptualisme
The reaction against conceptualism emerged in the mid-twentieth century. The Mouvement du Droit Libre, influenced by Rudolf von Jhering’s jurisprudence of interests, argued that legal decisions are determined by the judge’s sense of justice rather than by the logical application of concepts.
In France, the sociological jurisprudence of Léon Duguit and Georges Gurvitch challenged positivist and conceptualist orthodoxy. Duguit, in his Traité de droit constitutionnel (1911), argued that law is a product of social solidarity, not state command, and that the state is bound by legal rules just as individuals are.
Gurvitch’s L’idée du droit social (1932) developed a pluralist theory of law that recognised normative orders — including professional, religious, and customary orders — alongside state law. Gurvitch’s critique exposed the limitation of state positivism in accounting for the normative complexity of modern societies.
The realist critique has been influential in contemporary French legal theory. The École de la sociologie juridique, associated with Jean Carbonnier and André-Jean Arnaud, emphasises the empirical study of law in action rather than the formal analysis of legal texts.
Contemporary Positivism
French legal positivism in the twenty-first century has evolved beyond the strict formalism of the exegetical school. Contemporary positivism, represented by jurists such as Michel Troper, Denys de Béchillon, and Olivier Jouanjan, incorporates insights from legal realism, systems theory, and constitutional theory.
Troper’s théorie réaliste de l’interprétation (realist theory of interpretation) argues that interpretation is an act of will rather than cognition. The interpreter — whether judge, administrator, or citizen — creates the meaning of the legal text through the act of interpretation, within the constraints imposed by the legal system’s interpretive conventions.
De Béchillon’s work on autorité et hiérarchie (authority and hierarchy) explores the relationship between legal validity and the structure of legal systems. His positivism emphasises the role of recognition rules and chains of validity in grounding the normativity of law.
Jouanjan has developed a théorie de la connaissance juridique (theory of legal knowledge) that integrates positivism with hermeneutics. His work recognises the interpretive character of legal knowledge while maintaining the distinction between legal and moral reasoning.
Contemporary French positivism has also engaged with the challenges posed by European legal integration. The supremacy of EU law, the direct effect of directives, and the jurisdiction of the European Court of Human Rights have required French positivism to account for the fragmentation of legal authority beyond the nation-state.
Conclusion
French legal positivism has evolved from the strict textualism of the exegetical school, through the state positivism of Carré de Malberg and the system-building of Gény and Saleilles, to the sophisticated contemporary theories of Troper, de Béchillon, and Jouanjan. Despite criticisms from sociological and realist perspectives, positivism remains the dominant methodological approach in French legal scholarship and judicial reasoning.
