The Greek legal system belongs to the family of Roman systems. Its basic elements reflect the influence of both the German and French law. Greece is also a member State of the EU (since 1981), therefore EU law covers a large part of internal law.
According to the Constitution of 1975/86/01, Greece is a presidential parliamentary multi-party republic of western type, based on the principles of human dignity, popular sovereignty, distinction of powers, and rule of law. The Constitution protects a large catalogue of fundamental rights (civil liberties, political rights, social rights, and rights of “3rd generation”). All courts have the power to control the constitutionality of laws (non existence of a Constitutional Court). All ratified international conventions as well as all generally recognized rules of international law prevail over domestic laws.
