Illinois Statutes Chapter 65. Municipalities §-17 5/3.1-10-17. Term limits

(a) The imposition of term limits by referendum, ordinance, or otherwise must be prospective. Elective office held prior to the effective date of any term limit imposed by a municipality shall not prohibit a person otherwise eligible from running for or holding elective office in that municipality. Term limits imposed in a manner inconsistent with this Section remain valid prospectively, but are invalid as they apply to service prior to the enactment of the term limits.

(b) The imposition of term limits by referendum, ordinance, or otherwise shall only apply to terms for the same office or that category of municipal office. Term limits imposed in a manner inconsistent with this subsection are invalid as they apply to service in other categories of municipal offices.

(c) A home rule unit may not regulate term limits in a manner inconsistent with this Section. This Section is a limitation under subsection (i) of Section 6 of Article VII of the Illinois Constitution on the concurrent exercise by home rule units of powers and functions exercised by the State.

(d) This Section applies to all term limits imposed by a municipality by referendum, ordinance, or otherwise passed on or after November 8, 2016.
