Each municipal corporation in this state whose annual ad valorem tax rate is otherwise limited by the Constitution or any amendment thereto less than one and one-fourth per centum (1 1/4 %) of the value of the property situated therein as assessed for state taxation during the preceding year shall have, in addition to the power to levy and collect such ad valorem tax each year at the rate authorized immediately prior to the adoption of this amendment, the further power to levy and collect each year an additional tax or taxes to such extent that the total ad valorem tax rate of such municipal corporation shall not exceed one and one-fourth per centum (1 1/4 %) in any one year on the property situated therein based on the valuation of such property as assessed for state taxation during the preceding year; provided, that before any such additional tax may be so levied and collected a majority of the qualified electors of any such municipal corporation voting at an election called for that purpose shall vote in favor of the levy thereof; provided further, that the total ad valorem tax or taxes to be levied and collected by any such municipal corporation shall not exceed one and one-fourth per centum (1 1/4 %) in any one year; and provided further, that the adoption of this amendment shall in no wise affect, limit, modify, abridge or impair the power, authority or right of any such municipal corporation to levy and collect the special school taxes now or hereafter vested or conferred upon them, or any of them, under the Constitution or any amendment thereto, which said special school taxes shall be in excess of said one and one-fourth per centum (1 1/4 %) herein provided for. Each election held under the provisions hereof shall be ordered, held, canvassed and may be contested in the same manner as is or may be provided by the law applicable to municipal corporations for elections to authorize the issuance of municipal bonds. The ballots used at such elections shall specify the purpose for which the proposed additional rate of taxation shall be authorized and shall contain the words "For ... % additional rate of taxation"; and "Against ... % additional rate of taxation"; the additional rate of taxation proposed to be shown in the blank space provided therefor. The voter shall record his choice, whether for or against the additional rate shown, by placing a cross mark before or after the words expressing his choice. The proceeds of any such additional tax so authorized at any such election shall be used only for the purpose for which the same shall be authorized at such election. Elections to authorize the levy of such additional tax may be held as often as ordered by the governing body of the municipality, but when a proposition is submitted to the electors to levy such additional tax for a specific purpose and such proposition is defeated then no second election for the same purpose shall be held in one year thereafter.
