Final answer:
The American judicial system includes both federal and state courts with the U.S. Supreme Court at the top. Federal district courts serve as trial courts, the courts of appeal review cases from district courts, and the Supreme Court is the final arbiter of federal legal matters. All levels of court are governed by the principle of precedent, and federal judges have lifetime tenure.
Step-by-step explanation:
Structure of the American Judicial System
The American judicial system is a dual court system that includes both federal and state courts, with the U.S. Supreme Court at the pinnacle. Federal courts adhere to a three-tiered structure comprising federal district courts, courts of appeal, and the Supreme Court.
Federal District Courts
The federal district courts are the trial courts of the federal system. This is where cases begin, and extensive processes involving witnesses, evidence, and arguments take place. Each state has at least one district court.
Courts of Appeal
Above the district courts are the U.S. courts of appeal, also known as the circuit courts. These appellate courts review the decisions of the district courts. If a party loses a case in the district court, they can appeal to the circuit court.
The Supreme Court
The U.S. Supreme Court is at the top of the federal hierarchy. It is the final arbiter of appeals from the circuit courts and state supreme courts when a substantial federal question is involved. However, due to the high volume of appeals, the Supreme Court hears only a fraction of the cases, selecting those that have a significant impact on the law and public policy.
Each level of court is guided by the principle of precedent, ensuring consistency and stability in the legal system. Judges and justices are appointed by the president and confirmed by the Senate, enjoying lifetime tenure, which allows for independence in their decision-making.
