District fédéral
The Judiciary Act of 1789 had created, in addition to the Supreme Court authorised by the Constitution, two lower levels of courts. Federal district courts, each with a district judge, composed the lowest level. Their district boundaries generally matched state lines. Every federal district also fell within the circuit of one of the three second-level courts, the circuit courts. Two Supreme Court justices and one district judge composed each circuit court bench; they traveled to each district to hear cases twice a year, at locations and times specified by statute.
