This description refers to Court of international trade.
The Court possesses limited subject matter jurisdiction, meaning that it may hear only cases involving particular international trade and customs law questions. Most cases are heard by a single judge. If a case challenges the constitutionality of a U.S. law or has important implications regarding the administration or interpretation of the customs laws, then it may be heard by a three-judge panel. Many Judges of the Court of International Trade also regularly sit by designation on three-judge panels of the United States Court of Appeals for the Second Circuit.
