How Illinois Judges Are Selected, Elected, and Retained

Illinois uses a merit-based retention system layered on top of partisan electoral contests to staff its judiciary — a structure that distinguishes it from states that rely exclusively on gubernatorial appointment or nonpartisan elections. Judges at every level of the Illinois court system, from circuit courts to the Illinois Supreme Court, enter the bench through competitive elections and remain there only if voters approve their continuation in office. The Illinois Constitution of 1970 governs the entire framework, and the Illinois Supreme Court administers the rules that regulate candidate eligibility, campaign conduct, and retention procedures.

Definition and scope

Illinois judicial selection operates under Article VI of the Illinois Constitution of 1970, which establishes a three-tier court structure: the Supreme Court (7 justices), the Appellate Court (currently 54 authorized judges across 5 districts), and the circuit courts (at least 507 authorized circuit judgeships distributed across 24 circuits). Each tier uses the same basic mechanism — initial partisan election followed by nonpartisan retention votes — but the geographic scope and term lengths differ by level.

This page covers Illinois state court judicial selection exclusively. It does not address federal judicial appointments within Illinois, which fall under Article II of the U.S. Constitution and the Senate confirmation process applicable to the Northern, Central, and Southern Districts of Illinois. Tribal court appointments, administrative law judges appointed by Illinois executive agencies, and associate judges selected by circuit court judges are adjacent categories with distinct processes not fully detailed here. For the broader regulatory landscape governing Illinois courts, the Regulatory Context for Illinois U.S. Legal System page provides foundational framing.

The Illinois Courts Commission and the Illinois Judicial Inquiry Board (705 ILCS 55) provide oversight of judicial conduct but are not part of the selection mechanism itself.

How it works

Illinois judicial selection follows a structured sequence with four distinct phases:

Initial candidacy declaration. An attorney seeking a circuit court judgeship must declare candidacy in the partisan primary for either the Democratic or Republican ticket, or collect signatures to appear on the general election ballot as an independent or third-party candidate. Illinois Supreme Court Rules and the Illinois Election Code (10 ILCS 5) govern petition requirements, filing deadlines, and candidate eligibility. Candidates must be licensed to practice law in Illinois.
Partisan general election. Successful primary candidates compete in a contested partisan general election. Voters in the judicial subcircuit or district elect the judge by simple majority. Circuit court judges serve 6-year initial terms; Appellate Court judges serve 10-year initial terms; Supreme Court justices serve 10-year initial terms (Illinois Constitution, Art. VI, §§ 10–12).
Retention election. At the end of each term, a sitting judge who wishes to continue must appear on a nonpartisan retention ballot — no opponent, no party label. Retention requires a 60 percent affirmative vote of those voting on the question, a threshold set by Article VI, Section 12 of the Illinois Constitution. This supermajority requirement is more demanding than the simple majority used in states such as Iowa or California.
Vacancy appointment. When a vacancy arises mid-term — through death, resignation, or removal — the Illinois Supreme Court fills Supreme Court vacancies, and the circuit judges of the relevant circuit fill circuit court vacancies, by appointment. The appointed judge serves until the next general election at which the position appears on the ballot.

Associate judges, a subordinate category within circuit courts, are selected exclusively by vote of the circuit judges — not by the general electorate — and serve 4-year terms under Article VI, Section 8.

The Illinois Courts website (illinoiscourts.gov) publishes the current roster of judges, their circuit assignments, and upcoming retention election calendars.

Common scenarios

Uncontested retention. The vast majority of Illinois judges face uncontested retention ballots and receive affirmative votes well above the 60 percent threshold. The Illinois Judges Association and the Illinois State Bar Association (ISBA) publish judicial performance evaluations that inform voter decisions on retention ballots, though these evaluations carry no binding legal weight.

Failed retention. Retention failures are uncommon but not without precedent. In 2014, three Illinois Supreme Court justices faced serious retention challenges following campaign finance controversies, though all three ultimately retained their seats. When a judge fails to reach 60 percent approval, the seat is treated as a vacancy and filled through appointment.

Subcircuit elections. Cook County uses a subcircuit system dividing the county into 15 geographic subcircuits for circuit court elections, a structure created through a 1991 constitutional amendment. This affects candidate residency requirements and the geographic scope of each election.

Mid-term vacancies. A circuit court vacancy arising more than 28 months before the next general election permits the circuit's judges to appoint a replacement who then faces a partisan general election to complete the unexpired term. A vacancy arising within 28 months allows appointment through the remainder of the term without a general election contest (10 ILCS 5/25-10).

For context on how these judges function within the court structure, Illinois Appellate Court Process and Illinois Supreme Court Role describe the distinct jurisdiction each bench exercises.

Decision boundaries

The Illinois judicial selection framework has identifiable limits that define where its authority ends and other mechanisms begin.

Geographic scope. The selection process described here applies to Illinois state court judges only. Federal district court judges in Chicago and across Illinois are appointed by the President of the United States with Senate confirmation under 28 U.S.C. § 44 and are not subject to Illinois retention elections.

Judicial discipline vs. selection. Removal of a sitting judge before term expiration is not a function of the electoral process. The Illinois Judicial Inquiry Board investigates complaints and may recommend removal proceedings before the Illinois Courts Commission (705 ILCS 55/§§1–19). Electoral defeat or retention failure is distinct from disciplinary removal and carries no findings of misconduct.

Campaign finance. Illinois judicial candidates are subject to campaign contribution limits set by the Illinois Campaign Financing Act (10 ILCS 5/9-8.10) as administered by the Illinois State Board of Elections. These limits differ from those applicable to legislative or executive candidates.

Bar admission requirement. Candidacy requires Illinois bar admission — active licensure in good standing as administered by the Illinois Supreme Court under Illinois Supreme Court Rule 711 and the broader Illinois Attorney Licensing and Bar framework. Out-of-state attorneys without Illinois admission cannot seek Illinois judicial office.

Not covered. This page does not address the selection of administrative law judges appointed within Illinois executive agencies, nor the internal merit selection processes some bar associations have proposed as alternatives to partisan elections. The Illinois Administrative Law Overview page covers the administrative hearing officer structure separately.
