§ 90. Reconsideration of ordinance protested by petition; submission of ordinances to voters.

If within the period of five days after the passage of any ordinance a petition signed by sufficient qualified voters of said city, being in number at least fifteen percent of the votes cast for all the candidates for the office of mayor at the last preceding regular municipal election, shall be filed protesting against such ordinance, or any part thereof, taking effect, such ordinance, or such part thereof so protested against, shall thereupon and thereby be suspended from taking effect, and the city council shall immediately again consider the same, and if it be not repealed or so amended as to meet the requirements of the said protest, the city council shall submit the same for ratification or rejection to the qualified voters of the city at the next regular municipal election which shall be held not more than thirty days after such petition is filed, or at a special election to be called thereafter by the city council for that purpose to be held in not less than sixty days nor more than ninety days after such petition is filed, and such ordinance, or part thereof so protested, shall not take effect unless a majority of the votes cast at such election thereon shall be for the ratification thereof. If such petition shall only be signed by sufficient qualified voters to equal in number at least five percent but not sufficient to equal in number at least fifteen percent of the votes cast for the candidate for said office of mayor at the last preceding municipal election, the city council shall submit such ordinance, or such part thereof so protested, for ratification or rejection at the next ensuing regular municipal election which is to be held more than thirty days after such petition is filed. The city council may, on its own motion, without any petition being required therefor, submit at a regular or special municipal election any ordinance passed by it in the same manner and with the same force and effect as hereinbefore provided. No ordinance, or part of an ordinance, rejected at any election shall be enacted or passed by the city council within the period of twelve months thereafter.
