Council action on a petition for any proposed ordinance, referendum, or charter amendment shall be by ordinance. No city officer may consider the subject matter of a petition when determining the legal sufficiency thereof, except as required to assure compliance with applicable provisions of this charter, general laws of the state, or ordinance of council. Any petition and any signatures upon the part-petitions thereof found to be sufficient as provided herein shall be presumed to be in all respects sufficient, unless not later than forty-five days before the election, it shall be otherwise proven.
