(A) Attorney. It shall be the duty of the City Attorney to prepare such ordinances as may be required by the City Council.
(B) Introduced. When a proposed ordinance is introduced, it shall be read one time by title only and referred to the proper committee unless the City Council shall otherwise specifically direct.
(C) Vote required; yeas and nays record.
(1) The passage of all ordinances for whatever purpose, and of any resolution or motion: to create any liability against a city; or for the expenditure or appropriation of its money, shall require the concurrence of a majority of all members then holding office on the City Council, including the Mayor, unless otherwise expressly provided by the code or any other act governing the passage of any ordinance, resolution or motion; provided that, where the Council consists of an odd number of Alderpersons, the vote of the majority of the Alderpersons shall be sufficient to pass an ordinance.
(2) The yeas and nays shall be taken upon the question of the passage of the designated ordinances, resolutions or motions and recorded in the journal of the City Council.
(3) In addition, the corporate authorities at any meeting may by unanimous consent to take a single vote by yeas or nays on the several questions of the passage on any two or more of the designated ordinances, orders, resolutions or motions placed together for voting purposes in a single group.
(4) The single vote shall be entered separately in the journal under the designation “omnibus vote”, and in such event the Clerk may enter the words “omnibus vote” or “consent agenda” in the journal in each case in lieu of entering names of the members of City Council voting “yea” and of those voting “nay” on the passage of each of the designated ordinances, orders, resolutions and motions included in such omnibus group or consent agenda. The taking of such single or omnibus vote and such entries of the words “omnibus vote” or “consent agenda” in the journal shall be a sufficient compliance with the requirements of this section to all intents and purposes and with like effect as if the vote in each case had been separately by yeas and nays on the question of the passage of each ordinance, order, resolution and motion included in such omnibus group, and separately recorded in the journal. Likewise, the yeas and nays shall be taken upon the question of the passage of any other resolution or motion at the request of any Alderperson and shall be recorded in the journal.

(D) Ordinances; approval, veto.
(1) All resolutions and motions which create any liability against a city; or that provide for the expenditure or appropriation of its money; or to sell any city property, and all ordinances, passed by the City Council shall be deposited with the City Clerk. If the Mayor approved of them, he or she shall sign them. Those ordinances, resolutions and motions which the Mayor disapproves shall be returned to the City Council, with his or her written objections, at the next regular meeting of the City Council occurring not less than five days after their passage.
(2) The Mayor may disapprove of any one or more sums appropriated in any ordinance, resolution or motion making an appropriation, and, if so, the remainder shall be effective; however, the Mayor may disapprove entirely of an ordinance, resolution or motion making an appropriation. If the Mayor fails to return any ordinance or any specified resolution or motion with his or her written objections, within the designated time, it shall become effective despite the absence of the Mayor’s signature.
