The Council of State (Conseil d'État) was established during the period of the French Revolution, specifically in the revolutionary government structure set forth by the Constitution of the Year VIII (1799). This council functioned as a high administrative body, responsible for overseeing the application of laws and offering advice on matters of state. Under the leadership of Napoleon Bonaparte, who seized power through the Coup of 18 Brumaire (9 November 1799), the Council of State emerged as an essential element of the executive branch. Its members (known as councillors) were appointed by the First Consul (Napoleon himself initially) and were typically drawn from the ranks of experienced judges, legislators, and administrators. These councillors provided expert opinions on legal and administrative issues presented to them by the government. The Council of State played a crucial role in shaping the legal framework of France post-Revolution by drafting laws and decrees. For instance, it was instrumental in the formulation of the Napoleonic Code (Code Civil), which integrated various revolutionary principles into a unified civil law system. These codes affected numerous legal aspects, including property rights, family law, and the judicial process. One of the Council's notable functions was to act as the highest administrative court in France. As a judicial body, it addressed disputes between individuals and the state, ensuring the proper application of laws and safeguarding citizens' rights from potential governmental abuses. The Council of State's judicial decisions set important precedents for administrative law in France. The Council of State also had the authority to annul administrative acts that violated legal norms. This included the power to evaluate the legality of ordinances and regulations issued by local authorities and public administrations. By reviewing and nullifying unlawful acts, the Council helped maintain the rule of law during the flux of the revolutionary and Napoleonic eras. Although initially created to serve the revolutionary government, the structure and influence of the Council of State persisted well beyond the French Revolution. Its establishment marked a significant shift in the administrative and judicial apparatus of France, laying the groundwork for subsequent developments in public administration and law. The institution itself has continued to evolve, still functioning as a cornerstone of the French administrative judiciary system today.
