How Illinois Handles Emergency Admission
Illinois doesn’t use a nickname like “5150.” Its emergency psychiatric process — emergency admission by certification — lives in Article VI of 405 ILCS 5. It pairs a written petition with a clinician’s certificate, then moves quickly to a court hearing.
What Are the Criteria?
A person may be subject to involuntary admission when they have a mental illness and, because of it, are reasonably expected to physically harm themselves or others, are unable to provide for their basic physical needs so as to guard against serious harm, or are expected to suffer serious mental or emotional deterioration without treatment. (The exact statutory wording is set out in the Code’s definitions section.)
Who Can Initiate It?
A peace officer may take a person into custody and transport them to a facility. The petition itself can be executed by any person 18 or older, and must be accompanied by a certificate from a physician, qualified examiner, or clinical psychologist based on an examination.
How Long Before a Hearing?
After an emergency admission, the facility must file the petition and first certificate with the court within 24 hours (excluding weekends and holidays). The court then sets a hearing within 5 days (excluding weekends and holidays) of receiving the petition. The person is examined within 24 hours of admission. In practice this means the pre-hearing hold runs up to roughly five court days.
What Happens at the Hearing?
At the hearing, a judge decides whether the person meets the standard for involuntary admission. The person has the right to an attorney and to present evidence. If the court orders treatment, that order is time-limited and subject to review and renewal — it is not indefinite.
