On September 18, 2023, Illinois became the first state in the United States to fully eliminate cash bail when the pretrial detention provisions of the SAFE-T Act took effect. The change had an immediate and measurable impact on Cook County Jail, one of the largest single-site jails in the country.
What the SAFE-T Act Changed
Illinois's Pretrial Fairness Act (the pretrial portion of the broader SAFE-T Act, Public Act 101-0652) abolished the cash bail system statewide. Under the old system, a person charged with a crime was assigned a bail amount; if they could not pay — even a small fraction of it — they remained in jail until trial. Under the new system, a judge may order pretrial detention only if the prosecution proves the person poses a specific danger or flight risk. Everyone else is released on conditions.
The Impact on Cook County Jail's Population
Before the law took effect, Cook County Jail consistently held more than 7,000 people on any given day. Within months of the September 2023 implementation, the population dropped to roughly 5,000–5,500 — a reduction of nearly 30%. Sheriff Tom Dart and the Cook County court system reported that the overwhelming majority of people released under the new system were appearing for their court dates.
Opposition and Legal Challenge
The law faced significant opposition from some prosecutors and sheriffs. A coalition of 64 Illinois counties sued, arguing the pretrial provisions violated the state constitution. The Illinois Supreme Court rejected that challenge in July 2023 — before the law even took effect — ruling the legislature had the authority to restructure pretrial detention.
National Significance
Illinois's elimination of cash bail is closely watched by reformers and opponents alike in other states. New Jersey (2017) and Washington DC (decades-long low bail use) provided partial models, but no state had gone as far as a full statutory ban. Early data from Illinois challenges the argument that cash bail is necessary to ensure appearance at trial.
What It Means for People Awaiting Trial at Cook County Jail Today
Anyone held at Cook County Jail today is there because a judge made a specific finding of danger or flight risk under the detention standards of the Pretrial Fairness Act — not simply because they couldn't afford bail. Defense attorneys can request a detention review hearing to challenge that finding. The Cook County Public Defender's Office handles these hearings for people who qualify.
