Any member of a board, committee or commission of the Village may demand an "aye" or "nay" vote on any matter, and such vote shall be entered in the proceedings. Every member shall vote when a question is put unless the member has a conflict of interest, in which case the member shall make a statement on the record which explains the conflict to the satisfaction of the presiding officer, who may then excuse the member from voting. If the presiding officer has a conflict of interest, the presiding officer shall make such a statement on the record to the satisfaction of the members, who may then, by majority vote, excuse the presiding officer for the conflict of interest. A majority vote of all members of the board, committee or commission in favor of any proposed resolution shall be necessary for passage or approval, unless a larger number is required by statute. Except as otherwise provided, a majority vote of those present shall prevail in other cases.
