GBMI

Also written as: GBMI — Guilty but Mentally Ill

Guilty but Mentally Ill verdict acknowledging criminal responsibility while recognizing mental illness requiring treatment.

Full Definition

GBMI (Guilty but Mentally Ill) is a compromise verdict available in some jurisdictions that allows juries to find defendants criminally responsible while acknowledging their mental illness. Unlike NGRI verdicts, GBMI defendants are sentenced to prison terms but are supposed to receive psychiatric treatment during incarceration. This verdict was created partly in response to public concern about defendants 'getting off' due to insanity defenses. Critics argue that GBMI verdicts often result in inadequate treatment and may be used inappropriately when defendants don't meet insanity criteria but clearly suffer from mental illness. The availability and specific provisions of GBMI vary significantly across jurisdictions.
