COUNTY COURT.) (W. V. B.) In American law jurisdiction to try crimes and civil cases must be distinguished from venue or the place where the trial may be had. Jurisdiction as between the various States is governed by common law principles of the conflict of laws. The right to en force the judgment of one State in another State depends upon whether the former had jurisdiction of the subject matter and the parties, a fact which is always open to question by the courts of the latter State. But there being jurisdiction, the determina tion of the courts of the State in which the action is brought is conclusive upon the question whether the venue was properly laid. Constitutional or statutory provisions commonly govern the
venue of different causes of action as between particular counties and the Federal judicial districts. Actions such as trespass to land are ordinarily triable only in the State where the cause of action arose. Most actions may be tried in any State that has jurisdiction of the parties.
