Appellate court in the US

What is the function of the appellate court in the United States?

The primary function of the U.S. courts of appeals is to hear and dispose of the vast majority of cases appealed from the district courts.

United States Courts of Appeals

The 94 U.S. judicial districts are organized into 12 regional circuits, each of which has a United States court of appeals. A court of appeals hears appeals from the district courts located within its circuit, as well as appeals from decisions of federal administrative agencies.

In addition, the Court of Appeals for the Federal Circuit has nationwide jurisdiction to hear appeals in specialized cases, such as those involving patent laws and cases decided by the Court of International Trade and the Court of Federal Claims.
