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.
Politics of Greece
The Court of Cassation is the supreme civil and penal court, whereas the Council of State is the supreme administrative court. The Chamber of Accounts has an exclusive jurisdiction over certain administrative areas (for example it judges disputes arising from the legislation regulating the pensions of civil servants) and its decisions are irrevocable. This means that they are not judged at second instance by the Council of State.
