(10 ILCS 5/25-1) (from Ch. 46, par. 25-1) Sec. 25-1. Except as otherwise provided in Section 25-2, resignations of elective offices shall be made to the officer, court or county board authorized by law to fill a vacancy in such office by appointment, or to order an election to fill such vacancy. (Source: P.A. 88-419.)

(10 ILCS 5/25-2) (from Ch. 46, par. 25-2) Sec. 25-2. Events on which an elective office becomes vacant. Every elective office shall become vacant on the happening of any of the following events before the expiration of the term of such office: (1) The death of the incumbent. (2) His or her resignation. (3) His or her becoming a person under legal

disability.

(4) His or her ceasing to be an inhabitant of the

State; or if the office is local, his or her ceasing to be an inhabitant of the district, county, town, or precinct for which he or she was elected; provided, that the provisions of this paragraph shall not apply to township officers whose township boundaries are changed in accordance with Section 10-20 of the Township Code, to a township officer after disconnection as set forth in Section 15-17 of the Township Code, nor to township or multi-township assessors elected under Sections 2-5 through 2-15 of the Property Tax Code.

(5) His or her conviction of an infamous crime, or of

any offense involving a violation of official oath.

(6) His or her removal from office. (7) His or her refusal or neglect to take his or her

oath of office, or to give or renew his or her official bond, or to deposit or file such oath or bond within the time prescribed by law.

(8) The decision of a competent tribunal declaring

his or her election void.

No elective office, except as herein otherwise provided, shall become vacant until the successor of the incumbent of such office has been appointed or elected, as the case may be, and qualified. An unconditional resignation, effective at a future date, may not be withdrawn after it is received by the officer authorized to fill the vacancy. Such resignation shall create a vacancy in office for the purpose of determining the time period which would require an election. The resigning office holder may continue to hold such office until the date or event specified in such resignation, but no later than the date at which his or her successor is elected and qualified. An admission of guilt of a criminal offense that would, upon conviction, disqualify the holder of an elective office from holding that office, in the form of a written agreement with State or federal prosecutors to plead guilty to a felony, bribery, perjury, or other infamous crime under State or federal law, shall constitute a resignation from that office, effective at the time the plea agreement is made. For purposes of this Section, a conviction for an offense that disqualifies the holder of an elective office from holding that office shall occur on the date of the return of a guilty verdict or, in the case of a trial by the court, the entry of a finding of guilt. This Section does not apply to any elected or appointed officers or officials of any municipality having a population under 500,000. (Source: P.A. 94-529, eff. 8-10-05; 95-646, eff. 1-1-08.)

(a) Whenever it is alleged that a vacancy in any office exists, the officer, body, or county board who has authority to fill the vacancy by appointment, or to order an election to fill such vacancy, shall have power to determine whether or not the facts occasioning such vacancy exist. (b) On or before the 100th day previous to the day of election for which judicial candidates are to be nominated: (1) The Chief Justice of the Supreme Court shall

certify to the State Board of Elections the names of all judges who have died, resigned, retired or forfeited their office since the last general election and whose vacancies will be filled at the next general election.

(4) The State Board of Elections shall determine

whether the General Assembly has created new judgeships which are to be filled at the next general election.

If one of the events described in subsection (a) of Section 2A-9 of this Code occurs between the 100th day and the 92nd day previous to the day of election for which judicial candidates are to be nominated, the appropriate aforementioned officer shall promptly certify the vacancy to the State Board of Elections. (c) Except with regard to new judgeships which have been created by the General Assembly, the State Board of Elections may rely upon the certifications from the Supreme Court, the Illinois Courts Commission and the Secretary of State to determine (1) when vacancies in judicial office exist and (2) the judicial positions for which elections are to be held.

(e) Appointments made under this Section shall be in writing and shall be signed by members of the legislative or representative committee whose total votes are sufficient to make the appointments or by the Governor, as the case may be. Such appointments shall be filed with the Secretary of State and with the Clerk of the House of Representatives or the Secretary of the Senate, whichever is appropriate. (f) An appointment made under this Section shall be for the remainder of the term, except that, if the appointment is to fill a vacancy in the office of State Senator and the vacancy occurs with more than 28 months remaining in the term, the term of the appointment shall expire at the time of the next general election at which time a Senator shall be elected for a new term commencing on the determination of the results of the election and ending on the second Wednesday of January in the second odd-numbered year next occurring.
