La. Stat. tit. 33 § 2426
The commission, each member of the commission, and the director may administer oaths, subpoena witnesses, and compel the production of books and papers pertinent to any investigation or hearing authorized by this Part. Any person who fails to appear in response to a subpoena or to answer any question or produce any books or papers pertinent to any such investigation or hearing or who knowingly gives false testimony therein shall be subject to the penalties provided in R.S. 33:2432. In case of contumacy or refusal to obey a subpoena issued to any person, any district court within the jurisdiction of which the inquiry is carried on, or within the jurisdiction of which the person guilty of contumacy or refusal to obey is found, or resides, or transacts business, upon application by the commission, shall have jurisdiction to issue to the person an order requiring him to appear before the commission, its member, agent or agency and to produce evidence, if so ordered, or there to give testimony touching the matter under consideration or in question; and any failure to obey the order of court may be punished by the court as a contempt.
If any officer or employee in the city service or any officer or employee of the state or political subdivision of the state wilfully refuses or fails to appear before any court or judge, or any legislative committee, or any officer, board, or body authorized to conduct any hearing or inquiry, or if the employee or officer having appeared, refuses to testify or answer any question relating to the affairs or government of the city or the conduct of any city officer or employee on the ground that his testimony or answers would tend to incriminate him, or refuses to waive immunity from prosecution on account of any matter about which he is asked to testify at any such hearing or inquiry, he shall forfeit his position and shall not be eligible for appointment to any position in the classified service of the city for a period of two years.
