Miss. Code § 21-9-5
As soon as the returns of any election held hereunder for the adoption of the council-manager plan have been certified, and if a majority of the votes cast at such election were in favor of the council-manager form of government, the mayor of such city shall immediately certify to the secretary of state that such city, by special election, has adopted the council-manager form of government provided for herein, which certificate shall be recorded in a book kept for that purpose by the secretary of state. Such form of government shall then become effective on the third Tuesday after said adoption.
In case it shall appear by said election returns that a majority of the votes cast at such election were in favor of the existing form of government, then the mayor and councilmen or aldermen shall dismiss the petition, in which case no similar petition or ordinance shall be filed for a period of two years from the date of such order dismissing the petition, but nothing short of such election shall preclude the filing of such petition and the holding of another election at any time.
