13.3 The federal court system  (Page 2/15)

The circuit courts    started out as the trial courts for most federal criminal cases and for some civil suits, including those initiated by the United States and those involving citizens of different states. But early on, they did not have their own judges; the local district judge and two Supreme Court justices formed each circuit court panel. (That is how the name “circuit” arose—judges in the early circuit courts traveled from town to town to hear cases, following prescribed paths or circuits to arrive at destinations where they were needed.

While we often focus primarily on the district and circuit courts of the federal system, other federal trial courts exist that have more specialized jurisdictions, such as the Court of International Trade, Court of Federal Claims, and U.S. Tax Court. Specialized federal appeals courts include the Court of Appeals for the Armed Forces and the Court of Appeals for Veterans Claims. Cases from any of these courts may also be appealed to the Supreme Court, although that result is very rare.

On the U.S. Supreme Court , there are nine justices—one chief justice and eight associate justices. Circuit courts each contain three justices, whereas federal district courts have just one judge each. As the national court of last resort for all other courts in the system, the Supreme Court plays a vital role in setting the standards of interpretation that the lower courts follow. The Supreme Court’s decisions are binding across the nation and establish the precedent by which future cases are resolved in all the system’s tiers.

The U.S. court system operates on the principle of stare decisis    (Latin for stand by things decided ), which means that today’s decisions are based largely on rulings from the past, and tomorrow’s rulings rely on what is decided today. Stare decisis is especially important in the U.S. common law system, in which the consistency of precedent ensures greater certainty and stability in law and constitutional interpretation, and it also contributes to the solidity and legitimacy of the court system itself. As former Supreme Court justice Benjamin Cardozo summarized it years ago, “Adherence to precedent must then be the rule rather than the exception if litigants are to have faith in the even-handed administration of justice in the courts.”
