La. Public Officers and Employees § 42:80
When an action is brought against a person for usurping or intruding into or unlawfully holding or attempting to retain possession of a public office, the person who brings the action must set forth in the complaint the name of the person rightfully entitled to the office, with a statement of his right thereto.
In this case or in case the suit is brought by a claimant to the office on proof that the defendant is in bad faith holding or attempting to retain possession of a public office and in such bad faith has received fees or emoluments belonging to the office, the court may in its decree require the defendant to refund them and render judgment against him for the amount thereof as in other civil suits.
