Which court has the final decision-making authority on appeals?

The Supreme Court has the final decision-making authority on appeals within its jurisdiction. It serves as the highest court in the United States, and its rulings set a binding precedent for lower courts. This means that when the Supreme Court decides a case, that decision must be followed by all lower courts, ensuring uniformity and finality in the interpretation of law across the country.

The Supreme Court typically hears cases that involve significant constitutional questions, federal law interpretations, or conflicts among lower courts. Its ability to choose which cases to hear, often through the writ of certiorari, allows it to filter cases based on their importance and the broader implications of the rulings, emphasizing its role as the ultimate arbiter of legal disputes.

In contrast, the other options, such as District Courts, State Courts, and Circuit Courts, do deal with appeals but do not hold the same final authority. Their decisions can be appealed to higher courts, ultimately reaching the Supreme Court, which confirms its status as the final decision-maker in the judicial system.
