Constitutional court
The list below consists countries with separate constitutional courts. Yet some other countries do not have separate constitutional courts, but instead delegate constitutional judicial authority to their ordinary court system, with the final decision-making power resting in the supreme court. Nonetheless, such courts are sometimes also called "constitutional courts". For example, the Supreme Court of the United States has been called the world's oldest constitutional court because it was one of the earliest courts in the world to strike down a law as unconstitutional (Marbury v. Madison), even though it is not a separate constitutional court.
