Overview
The 2012 Illinois Supreme Court election was a pivotal judicial contest held during the general election on November 6, 2012. It determined who would fill the Third District seat vacated by the retirement of Justice Robert R. Thomas after more than a decade on the bench.
This election was part of Illinois’s unique system of electing supreme court justices through a combination of retention votes and contested elections. The Third District covers central Illinois and includes counties such as Kankakee, Will, and LaSalle.
- Justice Robert R. Thomas retired in January 2013 after serving since 2001, creating the vacancy filled in the 2012 election.
- Mary Jane Theis, then serving on the Illinois First District Appellate Court, ran as the Democratic-backed candidate for the seat.
- Jesse Reyes, an appellate judge from the First District, ran as the Republican candidate, making it a rare contested supreme court race.
- The election was decided by popular vote across the Third District, with Theis winning approximately 54.3% to 45.7%.
- This was one of the few contested Illinois Supreme Court elections in recent decades, highlighting growing judicial politicization.
How It Works
Judicial elections in Illinois follow a hybrid model combining initial appointments, retention votes, and occasionally contested elections. The 2012 race was unusual because it involved a direct election between two qualified candidates rather than a simple yes/no retention vote.
- Term: Supreme Court justices in Illinois serve 10-year terms. After initial appointment or election, they face retention votes to remain on the bench. A successful retention allows continuation for another full term.
- Selection method: Justices are elected from one of five geographic districts, with the Third District encompassing 40 counties in central Illinois.
- Eligibility: Candidates must be licensed attorneys with at least 10 years of experience and reside within the district they seek to represent.
- Partisan influence: Though judicial races are officially nonpartisan, candidates often receive party endorsements and campaign funding aligned with political affiliations.
- Ballot access: Candidates must file petitions with the Illinois State Board of Elections by mid-June to appear on the November ballot.
- Funding and ads: The 2012 race saw over $2 million spent on advertising, mostly from interest groups supporting or opposing each candidate.
- Voter turnout: The election coincided with the presidential race, boosting participation; statewide turnout reached 72.3%.
Comparison at a Glance
Illinois uses a different judicial selection model than most states. The table below compares key features of Illinois’s system with national norms.
| Feature | Illinois | National Average |
|---|---|---|
| Election Type | Partisan elections with retention votes | Merit selection or nonpartisan elections |
| Term Length | 10 years | 6–8 years |
| Selection Method | Initial election or appointment, then retention | Mix of appointment and election |
| Number of Justices | 7 | 7–9 (varies by state) |
| Contested Elections (2000–2020) | 5 | 12+ (in states with elections) |
The data shows Illinois has fewer contested supreme court elections than other states with elected judiciaries, such as Texas or Pennsylvania. However, when races do occur, they attract significant spending and media attention, as seen in 2012. The hybrid system aims to balance accountability and judicial independence but often results in politicized campaigns.
Why It Matters
The 2012 election had lasting implications for Illinois jurisprudence, particularly in areas like civil rights, criminal sentencing, and administrative law. Justice Theis’s victory preserved a progressive majority on the court during a period of significant legal change.
- Long-term impact: Theis later became Chief Justice in 2022, shaping court procedures and opinions for years after the 2012 win.
- Precedent setting: The court under Theis upheld key rulings on gun control, public pensions, and reproductive rights.
- Public trust: Contested elections raise concerns about judicial impartiality, especially when funded by special interest groups.
- Spending trends: The $2 million spent in 2012 set a precedent for future judicial races, with 2020 and 2022 races exceeding $3 million.
- Geographic equity: The district-based system ensures regional representation but can lead to disparities in campaign resources.
- Model critique: Critics argue Illinois should shift to a merit-based appointment system to reduce political influence.
Ultimately, the 2012 Illinois Supreme Court election exemplifies the complex intersection of law, politics, and public accountability in state-level judiciaries. It remains a reference point for debates over judicial independence and electoral reform.
