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.
Federal government of the United States
Separate from, but not entirely independent of, this federal court system are the court systems of each state, each dealing with, in addition to federal law when not deemed preempted, a state's own laws, and having its own court rules and procedures. Although state governments and the federal government are legally "dual sovereigns", the Supreme Court of the United States is in many cases the appellate court from the State Supreme Courts (e.g., absent the Court countenancing the applicability of the "doctrine of adequate and independent State grounds"). The Supreme Courts of each state are by this doctrine the final authority on the interpretation of the applicable state's laws and Constitution. Many state constitution provisions are equal in breadth to those of the U.S. Constitution, but are considered "parallel" (thus, where, for example, the right to privacy pursuant to a state constitution is broader than the federal right to privacy, and the asserted ground is explicitly held to be "independent", the question can be finally decided in a State Supreme Court—the U.S. Supreme Court will decline to take jurisdiction).
