Which court is the highest authority on constitutional interpretation in the United States?

• A. The U.S. Court of Appeals.
• B. The District Court.
• C. The State Supreme Court.
• D. The U.S. Supreme Court.

Answer: (D)

The fundamental idea is that the Constitution’s meaning is finally decided by the highest court in the land. The U.S. Supreme Court sits at the top of the judicial system and has the final say on constitutional questions. This authority comes from the Constitution itself (Article III) and was solidified in practice by the principle of judicial review established in Marbury v. Madison, which allows the Court to strike down laws or government actions that violate the Constitution. Because its interpretations bind every other court, all federal and state courts must follow Supreme Court rulings on constitutional matters. State courts’ interpretations of their own constitutions aren’t the ultimate authority for U.S. constitutional questions, since the Supreme Court’s rulings prevail on the federal Constitution.
