Not Guilty by Reason of Insanity (NGRI)
Not Guilty by Reason of Insanity (NGRI) is a legal status applied when a judge finds that an individual charged with a criminal offense was not able to appreciate the criminality of their actions due to their mental state at the time of the offense. This section explains the legal framework, clinical reporting, and pathways of treatment that follow an NGRI acquittal as outlined under Illinois law 730 ILCS 5/5-2-4.
Legal Context
In Illinois, the commitment of an individual found NGRI is not automatic. After an NGRI acquittal, Illinois law requires an evaluation and commitment hearing and sets limits on the length of court jurisdiction and IDHS supervision.
Clinical Context
The treatment goal for individuals found NGRI is to mitigate risk and support reintegration into the community through symptom stabilization, risk assessment, and continued care planning.
Commitment Pathways
Following an NGRI acquittal, a judge may order one of three commitment pathways depending on the individual’s clinical needs, level of risk, and treatment recommendations.
Right to Petition
Individuals found NGRI have the right to petition the court for a treatment plan review, conditional release, or discharge from IDHS custody.
Guardianship
If an individual found NGRI has or needs a guardian, the treatment team helps identify the appropriate type of guardianship and ensures the guardian is informed throughout the process.

About this Flowchart
This flowchart illustrates the NGRI process under 730 ILCS 5/5-2-4, beginning with an NGRI verdict and moving through evaluation, the commitment hearing, and into one of three legal pathways.
- Pathway 1 is an absolute discharge with no further IDHS involvement.
- Pathway 2 covers conditional release for individuals who need outpatient treatment and monitoring, including recurring hearings and a 5-year conditional release review.
- Pathway 3 covers secure inpatient treatment for individuals who require a higher level of care, with ongoing reporting, hearings, and the possibility of stepping down to conditional release.
All pathways are subject to the Thiem Date, which sets the maximum period of court jurisdiction and IDHS supervision.
