La. Stat. tit. 15 § 117
Upon being discharged for legal cause, the discharged grand jury or any of the discharged members may make applications for review directly to the supreme court. Such application must be made within two days from the date that the district judge ordered a discharge for legal cause, and shall be taken up by the supreme court, by preference, immediately over all other matters.
If, after the discharge by the district judge is ordered, application is made by the discharged grand jury or any of the discharged members as prescribed by law said grand jury or the members making application shall serve as before; and should the supreme court affirm the order of discharge or deny the application of the grand jury or any of its members, the validity of indictments shall in no wise be affected because they were brought in by the grand jury between the time that the district judge ordered a discharge for legal cause of the grand jury or any of its members and the time that the supreme court affirmed that order or denied the application.
Within two days after the order of the district judge discharging for legal cause, the grand jury or any of its members, is affirmed by the supreme court, or becomes final, the district judge shall make the necessary appointments to fill vacancies caused thereby as prescribed by law.
