US federal courts

The federal judiciary of the United States is one of the three co-equal branches of the federal government of the United States organized under the United States Constitution and laws of the federal government. Article III of the Constitution requires the establishment of a Supreme Court and permits the Congress to create other federal courts, and place limitations on their jurisdiction. Article III federal judges are appointed by the President with the consent of the Senate to serve until they resign, are impeached and convicted, retire, or die.

The federal courts are composed of three levels of courts. The Supreme Court of the United States is the court of last resort. It is generally an appellate court that operates under discretionary review, which means that the Court can choose which cases to hear, by granting writs of certiorari. There is therefore generally no basic right of appeal that extends automatically all the way to the Supreme Court. In a few situations (like lawsuits between state governments or some cases between the federal government and a state) it sits as a court of original jurisdiction.

The United States courts of appeals are the intermediate federal appellate courts. They operate under a system of mandatory review which means they must hear all appeals of right from the lower courts. In some cases, Congress has diverted appellate jurisdiction to specialized courts, such as the Foreign Intelligence Surveillance Court of Review.
