(A) Local Option. Each city having a population exceeding ten thousand but not exceeding four hundred thousand, each parish, and each parish governed jointly with one or more cities under a plan of government, having a population exceeding ten thousand, according to the latest official decennial federal census, may elect to be governed by this Part by a majority vote of its electors voting at an election held for that purpose. The election shall be ordered and held by the city, the parish, or the city-parish, as the case may be, upon (a) the adoption of an ordinance by the governing authority calling the election; or (b) the presentation to the governing authority of a petition calling for such an election signed by electors equal in number to five percent of the registered voters of the city, the parish, or the city-parish, as the case may be.
(B) Acceptance. If a majority of the electors vote to adopt this Part, its provisions shall apply permanently to the city, the parish, or the city-parish, as the case may be, and shall govern it as if this Part had originally applied to it. In such case, all officers and employees of the city, the parish, or the city-parish, as the case may be, who have acquired civil service status under a civil service system established by legislative act, city charter, or otherwise, shall retain that status and thereafter shall be subject to and be governed by this Part and the rules and regulations adopted under it.
(C) Rejection. If a majority of the electors vote against the adoption of this Part, the question of its adoption shall not be resubmitted to the voters of the political subdivision within one year thereafter.
