What the Illinois State’s Attorney Does
The Illinois State’s Attorney is the chief prosecuting attorney for each of the state’s 102 counties. In this role, the State’s Attorney decides whether to file criminal charges, oversees plea negotiations, and represents the state in court. The office investigates allegations, reviews evidence from law enforcement, and determines which cases proceed to prosecution. The position is elected, and officeholders serve set terms that vary by county, typically four years. Because prosecutorial decisions directly affect public safety and due process, the role is central to how justice is administered across Illinois communities.
County-Level Authority and Structure
Each county has its own State’s Attorney office, with jurisdiction limited to that county’s territory and, in many cases, adjacent municipal or circuit court matters. Offices range significantly in size and resources, from small rural counties with a handful of staff to large urban offices with dozens of prosecutors and support personnel. Responsibilities include filing charging instruments, conducting or supervising trials, and managing diversion or alternative prosecution programs. The office also works closely with law enforcement agencies, victim advocates, and court personnel to move cases through the system.
Typical Functions of an Office
- Reviewing police reports and deciding whether to press charges.
- Filing misdemeanor and felony prosecutions in local and circuit courts.
- Negotiating plea agreements and recommending sentences.
- Presenting cases to grand juries when required.
- Coordinating with victim services and witness protection programs.
How the State’s Attorney Is Elected
Illinois State’s Attorneys are elected in partisan or nonpartisan elections, depending on local rules, typically in even-numbered years during the primary and general election cycles. Filing deadlines and signature requirements are set by state election law and county election authorities. Because terms begin at different times by county, elections occur on staggered schedules. Voters can check their county’s board of election website for specific dates and candidate information.
Key Legal and Ethical Duties
State’s Attorneys must comply with state statutes, rules of professional conduct, and constitutional obligations, including open-file discovery and Brady obligations to disclose exculpatory evidence. Decision-making is guided by prosecutorial discretion, public safety priorities, and the need to pursue justice fairly. Many offices have formal policies on use of discretion, charging thresholds, and handling sensitive cases such as domestic violence and juvenile matters.
