Greek Constitutional Law is the body of law that governs the structure and function of the Greek government. It is primarily based on the Constitution of Greece, which was adopted in 1975 and outlines the rights of citizens, the organization of state institutions, and the principles of democracy. The Constitution establishes the separation of powers among the executive, legislative, and judicial branches. It also guarantees fundamental rights and freedoms, ensuring that all citizens are treated equally under the law. Amendments to the Constitution require a supermajority in the Hellenic Parliament, reflecting the importance of stability in the legal framework.
