French legal principles are based on the Civil Law system, which emphasizes written codes and statutes. The primary source of law is the Code Civil, established in 1804, which outlines fundamental rights and obligations. This system prioritizes clarity and accessibility, allowing citizens to understand their legal rights. Another key aspect is the principle of separation of powers, which divides government responsibilities among the legislative, executive, and judicial branches. This ensures that no single entity holds excessive power, promoting fairness and justice within the legal framework. Additionally, the French Constitution serves as the supreme law, guiding the legal system's operation.
