If a law is challenged as unconstitutional, which court would review it?

• A. District Court
• B. Supreme Court
• C. Tax Court
• D. Court of Appeals

Answer: (B)

The final interpreter of the Constitution is the Supreme Court. When a law is challenged as unconstitutional, the case typically starts in a trial-level court and can move up through the appellate system, but the Supreme Court is the highest authority with the power to rule on constitutional questions and set nationwide precedent. The Court of Appeals may review lower court rulings on these issues, and certiorari lets the Supreme Court decide whether to hear the matter at all. The District Court and the Tax Court handle different types of cases and do not provide the ultimate constitutional ruling. So, the Supreme Court is the best answer because it is the ultimate arbiter of constitutional validity.
