Louisiana Revised Statutes Tit. 18, § 674. Procedure

A. The proper official shall institute suit in the district court of the officeholder's designated domicile to obtain a judgment declaring the office vacant within ten days after the issuance of his opinion, if his opinion is that the officeholder no longer meets the residence or domicile requirements of his office. The matter shall be tried by preference over all other matters and, if the court shall find that the officeholder no longer meets the residence or domicile requirements of his office, a judgment shall be rendered declaring the office vacant, and the vacancy may be filled as provided by law.

B. A hearing on the petition for declaration of vacancy shall be held not more than twenty days after service upon the officeholder whose removal is sought. Judgment shall be rendered in the matter within ten days after trial. Either party may appeal the judgment suspensively within five days after the signing of the judgment, by obtaining an order of appeal and posting bond for a sum fixed by the court to secure the payment of costs. The trial judge shall fix the return day at a time not to exceed five days after the granting of the order of appeal. An application to the supreme court for a writ of certiorari may be made only within three days after the signing of judgment by the court of appeal. Each appellate court to which the action is brought shall place the matter on its preferential docket, shall hear it without delay, and shall render a decision within ten days after oral argument. The granting of an order of suspensive appeal or writ of certiorari suspends the effect of the judgment during the pendency of such proceedings.
