Miss. Code § 21-5-3
Every city operating under the commission form of government shall be governed by a council, consisting of the mayor and two (2) councilmen (or commissioners), each of whom shall have the right to vote on all questions coming before the council. The terms of office of the governing authorities in every such city, in office at the beginning of the term of office of the mayor and councilmen first elected under the provisions of this chapter shall then immediately cease and terminate. The terms of office of all other officers then in force in such city, whether elected or appointed, shall cease and terminate as soon as the council shall, by resolution, so declare.
The corporate name of every such city shall be "The City of (name of city)," under which name the council shall exercise and perform all the corporate powers, duties and obligations conferred or imposed on it or the members thereof.
Any city having a population of one hundred thousand (100,000) inhabitants according to the last decennial census and at that time governed by the commission form of government, may at any time, upon an election held as hereinafter provided, increase by two (2) the number of councilmen governing such city; provided that in no event shall the number of councilmen (not including the mayor) be increased to exceed ten (10) members. It shall be the duty of the council to call a special election on the question of the increase in the number of councilmen and upon receipt of a petition signed by at least ten percent (10%) of the qualified electors of such city, praying that an election be held to determine whether or not such city should increase by two (2) the number of councilmen under the commission form, and such special election shall be held in such city not less than thirty (30) days, nor more than sixty (60) days, from the date of making such order; but if a general election is to be held in such city within sixty (60) days from the making of such order, then the question of the increase in number of councilmen shall be submitted at such general election, rather than at a special election. Notice of such election shall be given as required by law, and the same shall be held and conducted as other elections in such city. At such election the propositions to be voted on shall be "FOR THE PRESENT NUMBER OF COUNCILMEN" and "FOR AN INCREASE BY TWO (2) IN THE NUMBER OF COUNCILMEN," and such propositions shall be printed on the ballot and the elector shall vote by placing a cross (X) or check mark (TICK) opposite his choice on the proposition. The results of such election shall be certified to the governing authorities of the city by the persons holding such election, and at their next regular meeting the governing authorities shall adjudicate on the minutes of the city whether or not the majority of the votes cast at such election were cast in favor of increasing by two (2) the number of councilmen. If a majority of the votes were so cast in favor of increasing by two (2) the number of councilmen in the commission form of government, then an order shall be entered providing for the election of the two (2) additional councilmen at an election to be held on the first Tuesday after the first Monday of June next thereafter. The mayor of the city shall immediately certify to the secretary of state that such city has by election determined to be governed by two (2) additional councilmen in the commission form of government and such certificate shall be recorded in a book kept for that purpose by the secretary of state. If a majority of the votes cast at such election be in favor of retaining the existing number of councilmen, the council shall so adjudicate by an order upon their minutes, and another election submitting the question of the increasing by two (2) the number of councilmen in the commission form of government shall not be held for a period of at least four (4) years thereafter.
