Any city may at any time, upon an election held as hereinafter provided, change the form of government of such city and adopt a commission form of government. It shall be the duty of the governing authorities of any such city to call a special election on the question of the adoption of the commission form of government upon receipt of a petition signed by at least ten per cent of the qualified electors of such city, praying that an election be held to determine whether or not such city shall abandon its existing form of government and adopt the commission form. Such special election shall be held in such city not less than thirty days, nor more than sixty days, from the date of making such order, but if a general election is to be held in such city within sixty days from the making of such order, then the question of the adoption of the commission form of government 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 FORM OF GOVERNMENT,” and “FOR THE COMMISSION FORM OF GOVERNMENT.” Such propositions shall be printed on the ballot and the elector shall vote by placing a cross (X) or check mark (✓) 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 the commission form of government. If a majority of the votes were so cast in favor of the commission form of government, then an order shall be entered providing for the election of officers provided for by this chapter at an election to be held on the first Tuesday after the first Monday of June next thereafter. The mayor or chief executive officer of the city shall immediately certify to the secretary of state that such city has by election adopted 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 the existing form of government, the governing authorities shall so adjudicate by an order upon their minutes, and another election submitting the question of the adoption of the commission form of government shall not be held for a period of at least four years thereafter.
