No matters shall be considered by Council which have not been properly placed upon the agenda, but provided that Council may amend the agenda and place new matters thereon by a two- thirds vote of Council members present at the commencement of the meeting at which such matter is to be considered, and further provided that nothing herein shall operate to prohibit the free discussion of business by Council nor simple orders directing preliminary work. Any matter denied consideration because of a lack of favorable vote by a two-thirds majority of those members present shall be placed on the agenda for the next Council meeting. This shall be the procedure followed at special and regular meetings of Council.
(1970 Code Sec. 2-17)
