The terms of two councilmen shall expire each year, except that in each third year, counting from 1963, the terms of the Mayor and of two Councilmen shall expire. When appointments are made to fill vacancies in the manner provided by Section 2.13(a) of this Charter, appointees shall qualify for and assume the duties of office within ten days after appointment, unless such time be extended for not more than sixty days by the Council. A person serving as a council member may not serve for more than two consecutive, full terms without a break in service for at least one full year. No member of the council shall serve more than four consecutive terms, as the mayor and a council member, without a break in service for at least one full year. Years of service of an appointee filling a vacated seat does not count toward the total term limit. (Amended 10/6/2020 election)
