La. Stat. tit. 38 § 1609
Any commissioner of a drainage district may be removed for cause by the police jury appointing the commissioner, upon petition of landowners owning a majority of the acreage in the district. The police jury shall without delay appoint a commissioner to fill the unexpired term of the one so removed, and the appointment shall be made in the manner provided in R.S. 38:1608. Failure or refusal of a commissioner to perform any or all of the duties prescribed by this Part, or his ceasing to possess the qualifications prescribed in R.S. 38:1607, or incompetency, dishonesty, or favoritism on the part of a commissioner, shall be good cause for removal. A commissioner shall always have the right to have the court pass upon the legality of his removal.
