In the United States, the term "circuit court" can refer to either the U.S. Circuit Court of Appeals or a state court with duties and jurisdiction that vary by state. Not every state has circuit courts.
Circuit courts originated at a time when most people lived in scattered communities across the country. A traveling judge would hold trials in each county within a designated territory called a circuit. This eliminated the need for each town to have its own court, judge and jail.
U.S Circuit Courts of Appeal
The United States is divided into 13 circuits represented by a U.S Circuit Court of Appeal. With the exception of defendants found not guilty, a dissatisfied party can appeal judgments made by a U.S District court in the Court of Appeal for his district. The Court of Appeals reviews the trial record for legal mistakes and determines if a judgment should be overturned.
