What is the highest court in the United States?

The highest court in the United States is the Supreme Court. This court holds the ultimate authority over all federal and state court matters regarding the interpretation of the U.S. Constitution, federal laws, and treaties. It serves as the final arbiter in legal disputes, ensuring uniformity and adherence to constitutional principles across all states. The Supreme Court's decisions cannot be appealed and establish binding precedent that lower courts must follow, making it the cornerstone of the judicial system in the country.

The other courts listed, such as the District Court, the Court of Appeals, and the Circuit Court, occupy lower levels in the judicial hierarchy. District Courts are the trial courts where cases are initially heard, while Courts of Appeals review decisions made by District Courts. Circuit Courts can refer to various levels of court depending on the state, but they, too, do not have the same authority as the Supreme Court to set nationwide legal precedents.
