What is the highest court in the United States judicial system?

The highest court in the United States judicial system is the Supreme Court. This court holds the ultimate authority in interpreting the Constitution and federal law, making it the final appellate court. It has the power to review decisions made by lower courts, including federal and state appeals courts, and its rulings set binding precedents across the entire country.

The Supreme Court's role is crucial in maintaining the rule of law and ensuring uniformity in the legal system. Its decisions address significant issues that impact American society and governance. This court also has the power of judicial review, which was established in the landmark case Marbury v. Madison, allowing it to declare laws and executive actions unconstitutional if they contradict the Constitution.

Regarding the other options, the District Court functions as a trial court rather than a court of final appeal, and the Court of Appeals primarily reviews cases decided by the District Courts. The term "Judicial Review Court" does not refer to any specific court in the U.S. judicial system. This distinction reinforces why the Supreme Court is recognized as the highest authority in matters of legal interpretation and the final arbiter of disputes arising under the law.
