(a)   All ordinance bills shall be prepared by the City Attorney.  No ordinance bill shall be prepared for presentation to Council unless ordered by a majority vote of Council, or requested in writing by the Mayor, or prepared by the City Attorney on his own initiative.
   (b)   All ordinances, resolutions and contract documents shall, before presentation to Council, have been approved as to the form and legality by the City Attorney or his authorized representative, and shall have been examined and approved for administration by the Mayor or his authorized representative, where there are substantive matters of administration involved.  All such instruments shall have first been referred to the head of the department under whose jurisdiction the administration of the subject matter of the ordinance, resolution or contract document would devolve and be approved by such department head; provided, that if approval is not given, then the same shall be returned to the Mayor with a written memorandum of the reasons why such approval is withheld.  In the event the questioned instrument is not redrafted to meet a department head objection, or objection is not withdrawn and approval in writing given, then the Mayor shall so advise Council and give the reasons advanced by the department for withholding approval.
   (c)   Ordinances, resolutions and other matters or subjects requiring action by Council must be introduced and sponsored by a member of Council; except, that the Mayor or City Attorney may present ordinances, resolutions and other matters or subjects to Council and any Councilman may assume sponsorship thereof by moving that such ordinances, resolutions, matters or subjects be adopted; otherwise, they shall not be considered.
   (d)   No ordinance shall be put on its final passage on the same day on which it was introduced.
   (e)   An ordinance shall not be materially amended at the same meeting at which finally passed.  If materially amended after publication the ordinance shall be republished and considered as though publication had not taken place.
