Answer:
First level is the federal district courts. Most lawsuits brought in the federal system start in the district court (although some go directly from state courts to the U.S. Supreme Court). The case must be brought in the district court that is related to the defendant or where the incident occurred.
The second level is the federal courts of appeals. As the name suggests, those who believe that the district court has misapplied the law or abused its discretion in the handling of their case appeal to these courts. The appeals courts within a circuit attempt to apply the law consistently within their circuit. They are bound only by the Congress and by U.S. Supreme Court, not the holding of the other circuits.
The third level is the U.S. Supreme Court. Some types of cases may be brought directly in the Supreme Court, but most travel from the federal district court through a circuit court of appeals, to the Supreme Court. The Supreme Court has four primary roles: determining if acts of the U.S. Congress are constitutional; reviewing state laws and court decisions for conflicts with the Constitution and acts of Congress; adjudicating conflicts between the states; and resolving conflicts between the federal circuit courts of appeals.
