All legislative action of Council shall be by resolution or ordinance introduced in written or printed form, each of which shall contain no more than one subject, which subject shall be clearly expressed in its title.
   An affirmative vote of at least 4 members of Council shall be required for the enactment of every resolution or ordinance, unless a larger number be required by the provisions of this Charter.
   Every resolution or ordinance shall be read at 3 different Council meetings, unless Council votes to suspend the rule of requiring separate readings, which reading or readings shall be by title only unless otherwise directed by a majority vote of Council. Such suspension of the rule shall require the affirmative vote of at least 6 members of Council if all members are present, or the affirmative vote of at least 5 members if one or more members are absent.
