The U.S. Court System
U.S. District Courts, U.S. Courts of Appeals, and the U.S. Supreme Court
There are three levels of courts in the federal court system in which a federal case can be heard: a U.S. District Court, a U.S. Court of Appeals, and the U.S. Supreme Court. A case is first heard in the district court and then can be appealed to a court of appeals, also known as an appellate court. After that, a case can be appealed to the U.S. Supreme Court.
Only a fraction of cases are ever heard by the Supreme Court; the judges on the appellate courts and district courts make the final decisions on most matters. This gives the judges of the “lower courts” — district courts and appellate courts — tremendous influence over how laws will be interpreted.
Judges in the federal courts are appointed for life by the President. This allows the President to have a major impact on how laws will be analyzed and implemented by the courts.
