Louisiana Revised Statutes Tit. 51, § 131. Venue; subpoenas

Any suit, action or proceeding under this Part in the name of the state against a corporation, shall be brought in the parish where it is domiciled, or if it has no domicile in this state, then in any parish in which it may be found or transacts business. Subpoenas for witnesses who are required to attend in any case, civil or criminal, may run into any other parish, but in civil cases no subpoena shall issue for witnesses living out of the parish in which the court is held at a greater distance than one hundred miles from the place of holding court without the permission of the trial court upon proper application and cause shown.
