The country is divided into 94 federal judicial districts, and in each district there is a United States district court. Each district court includes magistrate judges and a bankruptcy court.

These 94 districts are placed into 12 regional circuits, and each circuit has a court of appeals. The Federal Circuit Court of Appeals has nationwide jurisdiction and hears appeals in specialized cases. A party that is not satisfied with a final decision by a district court can appeal to the court of appeals and ask that the decision be reviewed.
End of the Line!
A party who loses a case in the court of appeals can ask the United States Supreme Court in Washington, D.C. to hear the appeal. Unlike a court of appeals, the Supreme Court hears only a very small percentage of the cases it is asked to review. The United States Supreme Court has the power to pick and choose what cases it will hear.
