At any election at which any ordinance or charter amendment is to be submitted to the voters the form of the notice shall be in accordance with applicable state law. The city secretary shall cause to be published one time, at least fourteen days before any such election, the arguments for or against such ordinances or charter amendments which may have been filed with the city secretary not less than twenty days before such election. Such arguments shall be signed by the person, persons, or officers of organizations who shall deposit with the city secretary at the time of filing a sum of money sufficient to cover the proportionate cost of publishing for the space taken by the arguments. The text of every ordinance or charter amendment shall also be displayed at the polling place in such election; but the validity of an ordinance or charter amendment approved by the voters shall not be questioned because of errors or irregularities in publication or display.
