Comprehensive Study Notes on General Constitutional Law and the Theory of the State

Foundations of Public Law and Constitutional Law

Conceptual Foundations of Public Law:
- Etymological Origin and Purpose: Public law derives from the Latin res publica, meaning "the public thing" or matters pertaining to the general interest and the governance of the polity (polis or city).
- The Summa Divisio: Originating in Roman law, the summa divisio represents the foundational partition encompassing all legal disciplines, separating law into private law and public law:
  - Private Law: Governs horizontal relationships established between private individuals on an equal footing.
  - Public Law: Fundamentally aims to satisfy the general interest and common utility. It constitutes a vertical legal order anchored in a relationship of command and authority. It regulates the relationships between the State and private individuals, governs the interaction between the State and its territorial domain, and organizes the operational framework of public authority.
Definition and Scope of Constitutional Law:
- Verbatim Scope: Constitutional law is the juridical discipline that establishes the principles and rules relative to the organization and functioning of public powers.
- Substantive Locus: It is housed primarily within the Constitution and pertains directly to the governance of the political community.
- Historical Omnipresence: Constitutional law is intrinsically tied to the existence of any organized political community. It is not exclusive to modern liberal societies; constitutional arrangements have existed across all historical epochs, dating back to Greek antiquity.
- Institutional Framework: It determines the functioning of public powers and applies comprehensively to the institutional mechanisms through which political power is established, exercised, and transmitted within the State.
Inherent Peculiarities and Nature of Constitutional Law:
- A Political and Ideological Discipline:
  - The discipline derives from the Greek concept of polis (the city) and is deeply imbued with political concepts.
  - Its principles and rules serve as the direct juridical translation of the dominant political philosophy within a society at a given historical juncture (e.g., within a liberal society, constitutional law is founded upon liberal philosophical principles).
- Imperfect Juridical Sanctions:
  - Unlike civil or tax law, constitutional law is characterized by highly imperfect legal sanctions and is frequently devoid of direct judicial penalties.
  - Violations of constitutional rules are not systematically adjudicated by a judge; sanctions are predominantly political rather than strictly judicial.
  - Illustrative Historical Example: The deployment and operation of the French Defense Council (Conseil de défense) during the COVID-19 health crisis between 2020 and 2022 demonstrated an executive management structure functioning outside traditional judicial constitutional oversight.
- Absence of Comprehensive Codification:
  - Constitutional law is not unified within a single "Constitutional Code."
  - The Constitution is a fundamental text that establishes broad, general rules rather than granular operational details; consequently, not all constitutional law is formally inscribed in the written document.
- The Primacy of Institutional and Governmental Practice:
  - The primary interpreters of the Constitution are those tasked with its direct execution: the government.
  - Governmental practice illuminates and clarifies the understanding of written constitutional texts, and constitutional norms may directly emerge from repeated institutional custom.
- The "Spirit of the Constitution" and Hermeneutics:
  - Mastering constitutional law requires looking beyond literal technical texts and strict juridical syllogisms to grasp the "spirit of the Constitution."
  - Comprehensive constitutional analysis requires an interdisciplinary foundation encompassing written texts, interpretative doctrines, institutional practices, historical contexts, political science, and general culture.
Core Pillars of Constitutional Study:
- The State: The primary entity whose public powers and authority are structured by constitutional norms.
- The Constitution: The supreme normative reference point governing the legal and political hierarchy.
- Political Regimes: The structural forms through which political powers operate (e.g., the contemporary French Fifth Republic, organized as a parliamentary regime).

The Classical Attributes of the State: Sovereignty

Constitutive Dimensions of Statehood: In public law and political philosophy, the State is universally defined by three decisive cumulative elements: a sovereign power, a demarcated territory, and a resident population.
Sovereignty as an Independent Power:
- Definition of Independence: Sovereignty represents an exclusive authority possessed solely by the State. Independence denotes the condition wherein an entity is entirely free from external subjection, possessing the capacity of self-determination without answering to any terrestrial superior.
- Historical Emergence in the French Monarchy:
  - The modern State is a historical construct that emerged at a specific juncture and is mortal. It arose in France at the close of the 13th century, particularly during the reign of King Philip the Fair (Philippe le Bel).
  - The French crown developed the theory of sovereignty to assert royal independence against three major competing jurisdictional rivals: the great feudal lords (les grands seigneurs), the Holy Roman Emperor, and the Pope (the ecclesiastical power).
  - Modern constitutional concepts of the State are directly inherited from these monarchical origins.
- Theoretical Formulation by Jean Bodin:
  - In 1576, the French jurist Jean Bodin systematized the theory of sovereignty in his seminal work, Les Six Livres de la République (The Six Books of the Republic).
  - Bodin defined sovereignty as an independent and absolute power: the sovereign monarch obeys no external earthly power and answers only to himself.
  - This conceptual framework was subsequently transposed from the physical person of the monarch to the abstract legal entity of the State.
- Application in Modern Public International Law:
  - A sovereign State is bound internationally only by virtue of its own sovereign will and autonomous consent.
  - Article 52 of the Vienna Convention on the Law of Treaties (May 23, 1969): Codifies that a treaty procured by the threat or use of force in violation of the principles of international law is fundamentally void, affirming that coercion destroys the sovereign consent necessary for legal validity.
Sovereignty as an Absolute Power:
- The Bodinian Definition: Bodin defined sovereignty as "the absolute and perpetual power of a republic" (la puissance absolue et perpétuelle d'une république).
- Nuances of the Term "Absolute":
  - Absolutus literally signifies "without ties" (sans lien), but it does not mean "without limits" (sans limite).
  - Under the Ancien Régime, the monarch's absolute power remained bound by divine law, natural law (precepts universally acknowledged by all human societies), and the fundamental laws of the kingdom (lois fondamentales du royaume, which governed royal succession).
  - Power is absolute in the sense that the sovereign possesses the prerogative to liberate himself from ordinary positive law in force, exercising unconstrained discretionary supremacy.
- Indivisibility and Absence of Degrees:
  - Sovereignty does not admit varying degrees; an entity cannot be "more or less" sovereign. Sovereignty is whole, unified, and indivisible.
- The Five Incompressible Sovereign Prerogatives (Marques de Souveraineté):
  1. The power to legislate (make the law), which includes the sovereign power to mint and issue monetary currency.
  2. The power to declare war and negotiate peace.
  3. The power to appoint public agents and officials.
  4. The power to judge in the last resort (adjudicative supremacy, embodied in the supreme power of cassation).
  5. The prerogative of mercy (the right of pardon, historically royal and currently presidential).
  - Fiscal Prerogative: The power to levy taxes is inextricably linked to these incompressible prerogatives, which cannot be stripped from a State without extinguishing its sovereign identity.
The Dual Facets and Contemporary Challenges to Sovereignty:
- Two Faces of the Same Coin: Sovereignty manifests outwardly as external independence (no terrestrial superior) and inwardly as internal supremacy (absolute, monopolistic authority over domestic jurisdiction).
- Supranational Integration vs. Sovereignty:
  - The European Construction: Member States of the European Union have consented to limit their sovereignty by delegating significant legislative, judicial, and monetary competencies to supranational institutions.
  - Limitation versus Abandonment: Because these limitations were instituted freely through international treaties, States retain the theoretical competence to unilaterally reclaim delegated powers. Juridically, this constitutes a self-imposed limitation rather than a definitive transfer or irreversible abandonment of sovereignty.
  - Doctrinal Schism: Contemporary constitutional debate remains polarized between the Europeanist current (favoring progressive integration and pooling of competencies) and the Sovereignist current (advocating strict retention of uncompromised national sovereignty).

The Classical Attributes of the State: Territory and Population

The Territorial Dimension of the State:
- Territory as the Material Base of Power:
  - Territory represents the physical and geographical space over which state authority is anchored, bounded by legally recognized frontiers.
  - Natural Frontiers: The historical consolidation of the French kingdom pursued physical frontiers (oceans, seas, mountain chains like the Pyrenees).
  - Imperative of Territory: A State cannot exist without a defined territory. However, geographical scale is legally irrelevant to statehood; micro-states possess authentic sovereign statehood regardless of restricted physical surface.
  - Monaco: Formally recognized as an independent sovereign State by the Franco-Monegasque Treaty signed on October 24, 2022.
  - Other Micro-States: The Principality of Andorra and the Vatican City State fulfill statehood criteria despite their minimal geographical footprints.
- Territory as a Frame of Competence:
  - State authority is strictly delineated by the principle of territoriality: domestic legislation applies universally across the national territory and ceases at its international borders.
  - The French Penal Code adheres to territoriality by penalizing offenses committed within the geographical borders of France.
  - Exceptional Extraterritoriality: Exceptional circumstances exist (such as the judicial confiscation of assets located abroad), but territoriality remains the governing jurisdictional principle.
The Demographic Dimension of the State:
- The Population as an Organized Collectivity:
  - Population is not an inert mass, but a structured human collectivity united by communal bonds residing upon the territory.
  - Demographic Management and Sedentariness: The State requires demographic measurement tools to enumerate its population. Sedentariness is an indispensable requirement of statehood; a purely nomadic population lacks permanent territorial fixation, preventing the formation of a State.
  - Demographic Extremes: A negligible population does not impede statehood. For example, Vatican City had a population of $825$ persons in 2019 and a surface area of less than $0.5\,\text{km}^2$ . Its population is fluid and transient, characterized by temporary citizenship that defies typical public law categorizations, yet it remains recognized as a State.
- The Concept of the Nation: Doctrinal Dichotomy:
  - The Objective Conception (German School - Johann Gottlieb Fichte): Conceives the nation as a biological, linguistic, and determinist community forged by blood ties, shared ancestry, common language, and inherited traditions.
  - The Subjective Conception (French School - Ernest Renan):
    - Articulated in Renan's foundational text, Qu'est-ce qu'une nation ? (What is a Nation?).
    - Defines the nation as a spiritual principle and a voluntaristic "will to live together" (vouloir vivre ensemble), famously described as a "daily plebiscite" (un plébiscite de tous les jours).
    - Doctrinal Nuance: This dichotomy is not absolute; even Renan acknowledges that a shared historical heritage is an objective component anchoring the subjective desire for union.
- Juridical Presence of "Nation" and "People":
  - Both terms are formal constitutional categories. Sovereignty resides in the people, who constitute an active, legally sovereign entity.
- Multinational and Multiethnic States:
  - Certain States encompass multiple distinct peoples or nations differentiated by language, ethnicity, historical narratives, culture, music, dress, and religion.
  - Such diverse configurations typically demand federalization to ensure stable coexistence on a shared territory.
  - Historical Case Study - Czechoslovakia (1918–1992): Constitutionally recognized two distinct national entities under Article 2, Paragraph 1 of its Constitution before undergoing peaceful partition.
  - Historical Case Study - Yugoslavia (1929–2006): Comprised a mosaic of distinct populations (Slovenes, Croats, Serbs, Bosniaks, Montenegrins, Macedonians, and Kosovars) historically dominated by Serbia. Deep religious divides (Orthodox Christianity, Roman Catholicism, Islam) and linguistic fractures prevented long-term cohesion, culminating in state dissolution.

The Unitary State: Principles, Centralization, and Variants

Foundational Characteristics of the Unitary State:
- Structural Unity: Characterized by administrative uniformity, an indivisible political power center, and the principle that domestic laws apply uniformly across the entire geographical territory.
- Political Unity:
  - Operates under a single constituent power and a single legislative authority.
  - Historical Realization in France: Political unity was initiated by the French monarchy and intensified by the French Revolution of 1789, which proclaimed the Nation "one and indivisible."
  - Constitutional Integrity: Article 5 of the 1958 French Constitution establishes the President of the Republic as the guarantor of national independence and territorial integrity. Constitutional revisions threatening territorial integrity are strictly prohibited.
  - The Indivisibility of the French People: Unlike the United States Constitution (1787), which accommodates distinct states within a federation, French constitutional dogma acknowledges only one singular people. In its decision of May 9, 1991 (Loi portant statut de la collectivité territoriale de Corse), the Constitutional Council struck down the legislative reference to a "Corsican people as a component of the French people" as unconstitutional.
- National and Linguistic Unity:
  - Ordinance of Villers-Cotterêts (1539): Promulgated by King Francis I, this statute mandated that all legal acts and administrative procedures be composed in the French language rather than Latin or regional dialects. It constitutes the oldest legal text in France that remains continuously in force.
  - Constitutional Codification: Article 2 of the 1958 Constitution explicitly states that "the language of the Republic is French."
  - Constitutional Council Decision of June 15, 1999: Declared the European Charter for Regional or Minority Languages contrary to the Constitution because its clauses granting recognized public usage of regional idioms infringed upon the constitutional indivisibility of the Republic and linguistic uniformity.
- Juridical Unity:
  - Unification entailed suppressing the Ancien Régime mosaic of provincial customs in favor of unified royal codification:
    - Edict of Moulins (1566): Regulated the legal system governing public waterways and canals.
    - Code Michau (Ordinance of January 15, 1629): Advanced legal and commercial harmonization.
    - Civil Ordinance of 1667 (Code Louis): Standardized uniform rules of civil procedure.
  - This legal unification reached completion through the revolutionary era, the Consulate, and the Napoleonic codifications.
Administrative Modalities within the Unitary State:
- Centralization:
  - A system in which political and administrative decision-making authority is monopolized by a single central headquarters (e.g., Paris), with zero autonomous local power.
  - Historical Evolution: Began under the monarchy via royal commissioners and intendants de province. Accelerated drastically during the Revolution, which championed absolute administrative equality across all territories, culminating in the division of France into standardized départements in 1790.
  - Napoleonic Consolidation: Under the Consulate (1799–1804), the landmark Law of 28 Pluviôse Year VIII (February 17, 1800) established the prefectural corps (préfets). Positioned at the apex of departmental hierarchies, appointed directly by the First Consul and completely subservient to the central government, prefects directed sub-prefects and appointed municipal mayors.
- Deconcentration:
  - An administrative technique designed to relieve central congestion: "deciding from afar rather than deciding everything from Paris."
  - Involves conferring decision-making authority upon central state agents deployed locally across territorial subdivisions.
  - Examples include Prefects, departmental state directorates (directions départementales de l'État), and the National Police, all operating under the strict hierarchical supervision and direct control of central ministries.
- Decentralization:
  - The structural counterpart to centralization, decentralization transfers distinct legal competencies from the central State to autonomous local territorial collectivities (collectivités territoriales: communes, departments, regions) endowed with distinct legal personality, budgetary resources, and elected governing councils.
  - Historical Trajectory in France:
    - Municipal Law of April 5, 1884: Mandated the election of mayors by universal suffrage through municipal councils, establishing modern municipal democracy.
    - Act I of Decentralization (Defferre Laws of March 2 and July 22, 1982): Transferred broad state competencies to local authorities and abolished the Prefect's a priori administrative tutelage, replacing it with a posteriori administrative and judicial control.
    - Constitutional Revision of March 28, 2003: Modified Article 1 of the Constitution to state: "The organization of the Republic is decentralized."
  - Critical Evaluation: Described as a "half-tone decentralization" (décentralisation en demi-teinte) or a "regime of supervised freedom." Local collectivities in France possess no legislative, judicial, or autonomous fiscal power; their administrative freedom is closely managed by the central State, often without adequate financial transfers to match allocated responsibilities.
- Regionalization (The Regional State):
  - An intermediate variant of the unitary State characterized by broad legislative, executive, and fiscal autonomy accorded to regional tiers, while stopping short of federalism.
  - The Italian Model:
    - Unified in 1860 from disparate kingdoms (e.g., Naples and Sicily), Italy established a unitary Republic through the Constitution of December 27, 1947.
    - Distinguishes between $15$ ordinary status regions (regioni a statuto ordinario) and $5$ special status regions (regioni a statuto speciale) endowed with heightened autonomy.
    - Each region possesses legislative powers exercised by an elected Regional Council (Consiglio Regionale) and executive power exercised by a Regional Junta (Giunta Regionale).
  - The Spanish Model:
    - The Spanish Constitution of 1978 balances the "indissoluble unity of the Spanish Nation" with the guaranteed right to autonomy for national minorities and regions (Article 2).
    - Structures the territory into $17$ Autonomous Communities (Comunidades Autónomas), each endowed with a unicameral regional parliament, a regional president, and an administrative government.
    - Judicial Subordination: Regional judiciaries remain structurally tied to the unified national judicial apparatus.
    - The 2017 Catalan Secession Crisis: Catalonia organized an illegal independence referendum followed by a unilateral declaration of independence. In response, Madrid invoked Article 155 of the Spanish Constitution, suspending regional autonomy to restore constitutional legality.

The Federal State: Structure and Competence Distribution

Nature and Genesis of the Federal State:
- The Federal Concept: A composite State (État composé) formed by the union of distinct federated entities that pool their sovereignty into a single federal government while retaining internal autonomy.
- Modes of Federal Emergence:
  - By Association (Centripetal): Independent States freely associate through a federal pact to create a shared political architecture. Examples: the Swiss Cantons, the United States of America, and Germany.
  - By Dissociation (Centrifugal): A unitary State internally decentralizes and reorganizes into a federal structure to manage internal diversity or geographic scale. Examples: Belgium, Russia, and Brazil.
- Distinction between Federation and Confederation:
  - Confederation: A treaty-based association of sovereign States that preserve their full independence and international legal personality, coordinating primarily over common markets and mutual defense.
  - The American Historical Trajectory: Following the 1776 Declaration of Independence, the $13$ former British colonies initially organized as a confederation under the Articles of Confederation before adopting the federal United States Constitution in 1787.
The Institutional Superposition of Authorities:
- A two-tiered governance structure characterized by dual constitutional orders, dual court systems, and dual executives and legislatures across both the federal and state levels:
- Federated Tier (The 50 US States):
  - Constitutional Autonomy: Each federated state possesses its own written constitution (e.g., the Fundamental Orders of Connecticut, the 1776 Virginia Constitution; the State of Louisiana has revised its constitution $10$ times).
  - Institutions: An executive branch headed by a Governor (an office from which $16$ US Presidents historically emerged), a bicameral legislature (comprising a State Senate and House of Representatives), and an independent state judiciary culminating in a State Supreme Court.
- Federal Tier (The United States Federal Government):
  - Constitutions and Branches: Operates under the federal Constitution of 1787, featuring an executive headed by the President, a bicameral Congress (the House of Representatives representing the population proportionally, and the Senate composed strictly of $2$ Senators per state), and a federal judiciary capped by the Supreme Court of the United States.
- Belgian Exception: Uniquely among modern federations, Belgium's federated entities lack distinct, autonomous written constitutions.
Constitutional Limitations on Federated Autonomy:
- Prohibition of Monarchical Forms: Federated entities are barred from adopting monarchical systems; the United States Constitution explicitly guarantees a republican form of government to every state.
- Withdrawn Sovereign Powers:
  - Military Defense: Exclusively reserved to the federal authority.
  - Diplomacy and Foreign Affairs: Federated states cannot conclude sovereign international treaties with foreign nations (in Germany, Länder may enter limited international agreements solely within their domestic competencies and subject to federal consent).
  - Monetary Sovereignty: The exclusive authority to issue currency belongs to the federal tier (entrusted to the Federal Reserve in the United States).
Mechanisms for Distributing Competencies:
- The Three Distribution Models:
  - Exclusive Federal Competence: The federal constitution explicitly enumerates exclusive central competencies (defense, foreign policy, monetary policy, federal justice, foreign commerce, citizenship). Any competence not explicitly assigned to the federal tier resides by default with the federated states (general competence of principle for states vs. enumerated attribution for the federal center).
  - Concurrent Competencies: Federated states retain authority to legislate over specific matters provided the federal government has not yet intervened with federal legislation.
  - Supportive Competencies: Federated entities exercise administrative competencies designed to execute and apply broad federal laws.
- The Theory of Implied Powers (Implied Powers):
  - Arbitration of jurisdictional conflicts between federal and state tiers falls to the federal supreme or constitutional court.
  - The United States Supreme Court expanded federal legislative competence via the doctrine of implied powers, affirming that Congress may enact legislation outside its enumerated powers if doing so is necessary to execute competencies already constitutionally conferred.

The Concept, Functions, and Forms of the Constitution

Foundational Functions of Constitutions:
- Limitation of Governmental Power:
  - Modern liberal constitutionalism emerged during the 18th century to eradicate monarchical despotism and arbitrary rule.
  - Benjamin Constant: Formulated in the 19th century that "all constitutions are acts of defiance" (toutes les constitutions sont des actes de défiance), shielding citizens against the despotism of single rulers or tyrannical legislative majorities.
  - Mechanisms of Moderation: Power is divided among independent organs to prevent its abusive concentration, operationalized through the tripartite separation of powers (legislative, executive, and judicial).
- The Constitutional Guarantee of Fundamental Rights:
  - Article 16 of the Declaration of the Rights of Man and of the Citizen (August 26, 1789): "Any society in which the guarantee of rights is not assured, nor the separation of powers determined, has no Constitution."
  - Evolution of Constitutional Declarations:
    - 1776: The American Declaration of Independence inaugurated explicit catalogs of fundamental rights functioning as constitutional complements.
    - 1789: The French Declaration of the Rights of Man prioritized first-generation individual liberties (private property, personal security, freedom of opinion, freedom of expression).
    - 1791 and 1793: The French revolutionary constitutions embedded explicit declarations of rights, though the Montagnard Constitution of 1793 was suspended immediately following its adoption.
    - Preamble of the 1946 Constitution (Fourth Republic): Introduced second-generation economic, social, and cultural rights (such as the right to work), which were absent in 1789. This text remains fully applicable in contemporary French constitutional law via its integration into the constitutional block (bloc de constitutionnalité).
Constitutional Forms: Written versus Unwritten:
- Written Constitutions:
  - Formulated explicitly to replace unwritten monarchical discretion with binding textual boundaries. The earliest modern written constitutions emerged in the United States (1787) and France (1789/1791).
  - 19th Century Proliferation: Accelerating across Europe, exemplified by the French Constitution of 1848, promulgated on January 31, 1850 (bearing structural affinities to the Charter of 1814).
  - 20th Century Authoritarian Uses: Even non-liberal regimes adopted written constitutions containing extensive bills of rights (e.g., the 1936 Constitution of the USSR, the 1975 Constitution of the People's Republic of China, the 1980 Chilean Constitution under Pinochet, and the Constitution of North Korea).
- Unwritten and Customary Constitutional Frameworks:
  - Absolute Rarity: No modern State operates under a purely unwritten constitution.
  - Ancien Régime France: A historical example of an entirely unwritten customary constitution, organized around time-honored practices regarded as legally binding (opinio juris), including male primogeniture and the principle of the indisponibility of the Crown (barring monarchs from altering the succession order).
  - The United Kingdom: Features a hybrid constitutional system formed by historic statutory documents alongside unwritten constitutional conventions:
    - Written Instruments: The Magna Carta (1215), signed by King John Lackland to curtail royal extraction; the Bill of Rights (1689), establishing individual rights such as personal security.
    - Unwritten Conventions: Structural norms established by institutional habit (e.g., the Prime Minister must formally petition the Monarch to dissolve the House of Commons, with the Monarch officially proclaiming the dissolution).

Elaboration and Revision: The Constituent Power

The Originating Constituent Power (Pouvoir Constituant Originaire):
- Definition: The legal power to establish an entirely new constitution for a State, typically exercised following a revolution, coup d'état, major systemic crisis, state formation, or liberation from foreign military occupation.
- Theoretical Foundations by Emmanuel-Joseph Sieyès:
  - In his 1789 pamphlet, Qu'est-ce que le tiers état ? (What is the Third Estate?), Abbé Sieyès established that the authority to frame a constitution belongs unconditionally to the sovereign Nation.
  - Because the sovereign answers only to itself, the originating constituent power is legally absolute, sovereign, and unbound by pre-existing procedural conditions.
- Modalities of Elaboration Across Political Regimes:
  - Monarchical Regimes: The Monarch exercises originating constituent authority directly, granting a constitution (charte octroyée) to the subjects without popular ratification.
  - Caesarist Regimes: The executive ruler (e.g., Napoleon I during the First Empire or Napoleon III during the Second Empire) drafts the constitutional text and bypasses deliberation by submitting it directly to popular plebiscite.
  - Representative Regimes: An elected assembly drafts and enacts the constitutional document on behalf of the people without a referendum (e.g., the constitutional laws of 1875 establishing the French Third Republic, framed exclusively by the National Assembly).
  - Democratic Regimes: The constitutional draft is formulated by an elected constituent assembly or committee and submitted directly to the citizenry for ratification via referendum (e.g., the French Constitution of 1848, and the Constitution of 1946, which required a second referendum after the initial draft was rejected by voters).
- Self-Imposed Constraints: The originating constituent power is fundamentally illimitable, constrained only by boundaries it imposes upon itself (e.g., the French Constitutional Law of June 3, 1958, which established substantive drafting conditions for the 1958 Constitution).
The Derived Constituent Power (Pouvoir Constituant Dérivé):
- Definition and Justification: The legally organized power tasked with amending an existing, valid constitution in response to societal transformation.
- Constitutional Affirmations: Title 7, Article 1 of the French Constitution of 1791 recognized the Nation's imprescriptible right to alter its constitution. Similarly, the Declaration of Rights of 1793 asserted: "A people has always the right to review, reform and change its Constitution. One generation cannot subject future generations to its laws."
- Rigid versus Flexible Constitutions:
  - Rigid Constitutions: Revisions demand complex, demanding procedural steps that differ from ordinary lawmaking:
    - France: Governed by Article 89 of the 1958 Constitution, which requires identical adoption by both parliamentary houses followed by either a referendum or an approval by a three-fifths majority of the Congress.
    - United States: Amending the Constitution requires ratification by three-fourths ( $\frac{38}{50}$ ) of the individual states.
  - Flexible Constitutions: Constitutional norms can be modified through the exact same legislative procedure used for ordinary laws (e.g., the United Kingdom, grounded in parliamentary sovereignty).
- Substantive Limits on Constitutional Revision:
  - Article 89 of the French Constitution of 1958: Prohibits constitutional amendments that compromise national territorial integrity or alter the "republican form of government" (a restriction dating back to the constitutional revision of 1875).
  - German Basic Law of 1949: The "eternity clause" (Ewigkeitsklausel) under Article 79(3) strictly bans amendments affecting fundamental rights or the federal structure.
  - Theoretical Vulnerability of Limits: These substantive limits can be legally bypassed by a two-stage revision: the derived constituent power can first repeal the article that imposes the substantive restriction, subsequently permitting the prohibited amendment.

The Jurisdictional Guarantee of the Constitution

The Imperative for Judicial Review:
- Constitutions represent fragile "paper barriers" easily circumvented by governing authorities. Without an external judicial mechanism to assess whether statutes comply with the supreme charter, constitutional supremacy remains purely theoretical.
Historical Evolution of Constitutional Control:
- The French Historical Resistance (Légicentrisme):
  - Rejection of Judicial Oversight: Under the influence of Jean-Jacques Rousseau, French revolutionary thought viewed the statute (la loi) as the sacred expression of the general will (l'expression de la volonté générale). Submitting parliamentary laws to judicial invalidation was condemned as an anti-democratic usurpation, pejoratively termed a "government of judges" (gouvernement des juges).
  - Abbé Sieyès' Unsuccessful Proposal: Sieyès repeatedly advocated for a jurie constitutionnaire (a specialized body to verify legislative conformity with the constitution), but his projects were rejected in 1791 and 1795.
  - Kersaint's Proposal: Deputy Armand de Kersaint similarly proposed a tribunal des censeurs in 1791, which was rejected.
  - Gradual Evolution: France transitioned toward judicial review in the mid-20th century: the Fourth Republic established a weak Constitutional Committee (Comité constitutionnel) in 1946; the Fifth Republic created the Constitutional Council (Conseil constitutionnel) in 1958, whose authority was later expanded by the 1974 constitutional reform (broadening parliamentary referral to $60$ deputies or $60$ senators) and the 2008 introduction of the priority preliminary ruling on constitutionality (QPC).
- The American Genesis: Marbury v. Madison (1803):
  - The United States Constitution of 1787 contained no textual provision granting the Supreme Court the authority to invalidate federal statutes.
  - The Precedent of February 24, 1803: In Marbury v. Madison, Chief Justice John Marshall established the judicial review of legislative acts. Marshall held that the Constitution is either a superior paramount law unchangeable by ordinary means, or it is on a level with ordinary legislative acts; if the former is true, an act contrary to the Constitution is void, and it is emphatically the province of the judicial department to say what the law is.
Functions of Constitutional Review:
- Guaranteeing Constitutional Supremacy:
  - The Kelsenian Pyramid: In the 1920s, Austrian legal theorist Hans Kelsen developed the normativist theory of law (Stufenbaulehre), establishing that legal norms are arranged in a strict hierarchy with the Constitution at the apex of the domestic legal order. Constitutional review enforces this hierarchy by invalidating inferior statutes that contradict higher norms.
- Protecting the Rule of Law (État de droit):
  - The Rule of Law requires that the State submit to its own legal norms, preventing arbitrary executive and legislative action while safeguarding fundamental rights.
Modalities of Constitutional Review: Action versus Exception:
- Review by Way of Action (Contrôle par voie d'action):
  - Nature: An abstract review initiated directly against a statute outside the context of a concrete legal dispute; often described as putting "the law on trial."
  - Access: Triggered by designated political authorities (e.g., in France: the President of the Republic, the Prime Minister, the President of the National Assembly, the President of the Senate, or $60$ deputies/senators) or directly by citizens (e.g., Germany, Spain, Italy) or local governments.
  - Timing: Can occur a priori (prior to legal promulgation, preventing an unconstitutional statute from taking effect) or a posteriori (following enactment, resulting in legal abrogation).
  - Structural Model: Constitutes a concentrated review (contrôle concentré) entrusted to a single specialized constitutional body (e.g., the French Constitutional Council).
  - Legal Effects: Rulings apply universally with erga omnes authority (binding against all parties across the legal order).
- Review by Way of Exception (Contrôle par voie d'exception):
  - Nature: A concrete, incidental review raised by a litigant during ordinary judicial proceedings as an affirmative defense, claiming that a governing statute violates the Constitution.
  - Timing and Forum: Operates strictly a posteriori within a diffuse review (contrôle diffus) framework, where ordinary judges possess jurisdiction to assess statutory constitutionality within their specific cases (e.g., the United States).
  - Legal Effects: If the judge finds the statute unconstitutional, the statute is not abrogated; rather, it is set aside (écartée) strictly for that individual dispute (relative effect between the parties).
- The French Hybrid Innovation (The QPC):
  - Implemented in 2010 pursuant to the 2008 constitutional revision, the Priority Preliminary Ruling on Constitutionality (Question prioritaire de constitutionnalité - QPC) permits individuals in a lawsuit to challenge an existing statute on constitutional grounds.
  - The ordinary judge does not rule on the statute's constitutionality directly; instead, the question is referred upward to the relevant supreme court (the Council of State for administrative courts or the Court of Cassation for judicial courts), which filters and transmits serious questions to the Constitutional Council for final concentrated review.

Political Regimes and the Separation of Powers

The Theory of the Separation of Powers:
- Typological Criterion: In constitutional doctrine, political regimes are classified based on their implementation of the separation of powers. Legitimate constitutional regimes structure their institutions around separated powers, whereas regimes that concentrate power are classified as autocratic.
- Philosophical Roots in Political Liberalism:
  - Rooted in the philosophical premise that political power is intrinsically dangerous and prone to abuse by human nature.
  - To preserve civil liberty, authority must be divided among distinct institutions, ensuring that "power checks power."
The Problem of Power: Thomas Hobbes:
- Biographical Context: Thomas Hobbes ( $1588$ - $1679$ ) was the first major modern thinker to conceptualize political power through the lens of human conflict.
- The State of Nature and Leviathan:
  - In Leviathan, Hobbes posits that the natural state of humanity is a "state of war of all against all" (bellum omnium contra omnes).
  - In this prepolitical condition, absolute human freedom inevitably causes mutual harm, leaving life "solitary, poor, nasty, brutish, and short."
  - Driven by the primal dread of violent death and the urge for self-preservation, human beings enter a covenant to surrender their natural freedom to an absolute sovereign: the State, personified as the biblical monster Leviathan.
  - Significance: Hobbes conceptualizes the initial monopolization of force, divesting individuals of the right to private justice and vesting total authority in the State to maintain public order.
The Moderation of Power: John Locke:
- Philosophical Counter-Perspective: Writing in direct opposition to Hobbesian absolutism, English philosopher John Locke published his Two Treatises of Government (Traité du gouvernement civil) in 1690.
- The Social Compact and Property:
  - Locke argues that the social contract is formed not to install an absolute ruler, but specifically to protect natural individual rights against governmental overreach.
  - The preeminent individual right in Locke's philosophy is the right to property, which serves as a core condition of human freedom.
- The Tripartite Distribution of Powers:
  - To prevent governmental tyranny and secure individual property, Locke proposed dispersing political authority across three distinct state powers:
    1. The Legislative Power: Entrusted with enacting general, uniform laws for the commonwealth.
    2. The Executive Power: Charged with executing and administering domestic legislation.
    3. The Federative Power: Responsible for managing external state security and international relations (treaties, alliances, war, and peace).
  - This Lockean division established the intellectual foundation for the separation of powers, subsequently adapted and expanded by Montesquieu to include the judicial power.
