The Mayor shall preserve order and decorum and shall decide questions of order subject to appeal to the Council. The Mayor may make motions, second motions or speak on any question, provided however, that in order to do so upon demand of any one Council member, the Mayor may vacate the Chair and designate the Mayor Pro Tem, if the Mayor Pro Tem is present, or if the Mayor Pro Tem is not present, a Council member to preside temporarily. The Mayor may vote on any matter before the Council.
