Miss. Code § 21-29-205
Whenever the said fund shall be created, and a system of disability and relief for firemen and/or policemen inaugurated in any municipality, at any time upon the petition of not less than twenty percent (20%) of the qualified electors of said municipality addressed to the said officers composing the governing board of said municipality, requesting an election to determine whether said municipality shall continue to operate under the provisions of this article, the said governing board of said municipality shall order an election to determine said question. Notice of the election shall be given and conduct of the election shall be had as is provided in Section 21-29-203. If at said election a majority of the qualified electors of said municipality shall vote against the continuance of operation of said municipality under the provisions of this article, the said governing board of said municipality shall at the next regular meeting thereof held after said election order the abolition and discontinuance of said system. The said fund and the said system, however, shall continue as to members of the paid fire department and/or police department of said municipality already in service and entitled to participation in said fund. The said system shall be worked out in said municipality to its end as to said members of the paid fire department and/or police department, but no new members entering the service of the fire and/or police department of said municipality shall be taken into or embraced within said system. If at said election a majority of the qualified electors of said municipality shall not vote for a discontinuance of said system in said municipality, no other election in said regard shall be held therein within a period of one (1) year thereafter. No new members may be joined by the fund after July 1, 1987, and all new employees of the police department and/or fire department of any municipality having such funds shall become members of the Public Employees' Retirement System of Mississippi after July 1, 1987.
