Advanced Transparency in the Use of Solitary Confinement 

2025 IMPACT

Public Act 103-1074 requires the Illinois Department of Corrections (IDOC) to collect and publish data quarterly and annually on the use of solitary confinement in its facilities. There are no limits in Illinois law on how long a person can be held in solitary confinement, despite its well-documented harms on the health and well-being of people who are incarcerated. This transparency measure will bring to light who is subjected to solitary confinement, why, and for how long. It will also provide information on access to health care in solitary, grievances appealing solitary, and available alternatives to solitary confinement. With these reports, legislators can identify opportunities to prioritize rehabilitation over punishment in future policymaking.
