How vacancies are filled in Illinois


If there is a vacancy in the Illinois General Assembly, the state constitution mandates that the seat must be filled by appointment when allowed by law. The appointment must be made within 30 days after the vacancy. If a vacancy occurs in the Senate with more than twenty-eight months remaining in the term, the appointment is interim until the next general election, when a special election must be held. All other House and Senate vacancies are to be filled by an appointment from the same political party that last held the seat.[1] If the vacated seat was held by an independent (no party affiliation), the governor is to appoint an independent successor within 30 days.[2]

The vacancy must be filled by the respective party organizations covering the legislative district.[3] The respective committeemen and committeewomen representing the legislative district must vote on a replacement.[4] The person selected for the seat serves for the remainder of the unfilled term.[5]
