The nisi prius courts are such as are held for the trial of issues of fact before a jury and one presiding judge. In America the phrase is familiarly used to denote the forum (whatever may be its statutory name) in which the cause was tried to a jury, as distinguished from the appellate court. See 3 BI. Comm. 58.
