The first meeting of a newly elected council shall be held on the first Monday following the certification of election of a majority of its members by the canvassing authority. The town clerk shall preside until the selection of a council president. The council shall determine the time and place of its regular meetings, but it must meet at least once each month. The president or a majority of the council may call a special meeting, but only by unanimous consent may the council meet sooner than forty-eight hours after each member has been notified of a special meeting. Four members of the council shall constitute a quorum.
