Constitutional Council (France)
The Government of France consists of an executive branch (President of the Republic, Prime Minister, ministers, and their services and affiliated organizations), a legislative branch (both houses of Parliament), and a judicial branch. The judicial branch is, unlike for instance the federal judiciary of the United States under the Supreme Court, not organized into a single hierarchy (administrative courts fall under the Council of State, civil and criminal courts under the Court of Cassation), and some of its entities also have advisory functions. For historical reasons there has long been a hostility to having anything resembling a "Supreme Court"—that is, a powerful court able to quash legislation. Whether the Council is a court is a subject of academic discussion, but some scholars consider it the supreme court of France.
Administrative courts in Greece
Greece, as a civil law country has administrative courts. The establishment of those courts can be found in article 94 of the Constitution of the Hellenic Republic 1975, as revised in 2001. The administrative courts are composed from districts Courts of First Instance, district Courts of Appeal and a Supreme Administrative Court that is called the "Council of State". The Council of State is also the Court of first and last instance in some important cases. The Greek administrative courts have jurisdiction upon litigations between the State and the civilians. The most important of them are tax cases, social security cases, tort liability of the State cases, illegal immigration cases etc.
