 When the new city plan of government was adopted, the mayor at the time, DeLesseps Story Morrison, was exempt from term limits due to a grandfather clause.Under the original Metropolitan Charter adopted in 1962, the mayor of Nashville was limited to three consecutive four-year terms, which was subsequently reduced to two consecutive four-year terms in 1991.Councilors were likewise limited to two consecutive four-year terms, but subsequent court rulings have determined the offices of district councilor and at-large councilor to be separate offices even though all councilors serve together in one unicameral body, which has meant that at large councilors have continued in office as district members, and (more frequently) district councilors have been elected to subsequent terms as at large councilors.
