§ 3.4. Quorum; votes.
(a)
A majority of the members of the council shall constitute a quorum to do business.
(b)
No member shall be excused from voting except upon matters involving the consideration of the member's official conduct or financial interest. In all other cases a failure to vote by a member who is present or who, having been present has withdrawn from the meeting without being excused, shall be deemed an affirmative vote and shall be so recorded. A member who has withdrawn from a meeting without being excused shall be counted as present for purposes of determining whether or not a quorum is present. The mayor shall be excused from voting only upon the same matters as a member.
