Miss. Code § 21-23-3
In all municipalities having a population of ten thousand (10,000) or more, according to the latest available federal census, there shall be a municipal judge and a prosecuting attorney, who shall be appointed by the governing authorities of the municipality at the time provided for the appointment of other officers. The municipal governing authorities may appoint one (1) additional municipal judge, who shall exercise the same authority and prerogatives of the office, regardless of the presence or absence of the other municipal judge. Except as otherwise provided in Section 21-23-5, a municipal judge shall be a qualified elector of the county in which the municipality is located and shall be an attorney at law. Such municipal judges and prosecuting attorney shall receive a salary, to be paid by the municipality, and to be fixed by the governing authorities of the municipality.
In any proceeding in which a conflict of interest arises for the prosecuting attorney, or any other reason dictates that he recuse himself, the mayor of the municipality may appoint a special prosecuting attorney for that particular proceeding. Such special prosecuting attorney shall be compensated for his services in the same manner and amount as allowed under Section 21-23-7 for appointed counsel for indigent persons.
Provided, however, the governing authorities of any municipality having a population in excess of ten thousand (10,000) persons according to the latest available federal census and situated in a county having an area in excess of nine hundred thirty-five (935) square miles and having a county court may, in their discretion, follow the provisions as set out in Section 21-23-5 for municipalities having a population of less than ten thousand (10,000).
