(a) All votes upon the passage of ordinances and resolutions, upon motions to suspend the rules, and upon motions to reconsider shall be by roll call vote. Any two members may demand a roll call vote upon any question to be voted upon by the council and when such demand is made the clerk shall call the roll.
(b) The council may by a majority vote of the members present adopt any method for tabulating the vote, including a random or alphabetical order of calling the roll.
(c) During a roll call vote on any question, it shall be out of order for any member to offer remarks as the member is voting other than a short and concise explanation of his vote. After a roll call vote, it shall be out of order for any member to offer any remarks on the question that had been voted upon.
(d) Members shall vote on all questions before the council except in situations where there is a conflict of interest or for other good cause. If a member fails to vote upon any matter, any other member may raise the question and insist that the member either vote or state the reason for not voting and be excused.
(e) Any member may change a vote before the result is announced, and afterwards by leave of the council provided that the change will not affect the result. In no case shall a member absent when the question is put be allowed to vote after the result is announced. (Ord. 79-97 § 2 (part), 1979).
