GBMI verdict

Pronunciation: G-B-M-I

Also written as: GBMI — Guilty But Mentally Ill

Guilty but mentally ill verdict allowing conviction with mandatory psychiatric treatment, alternative to NGRI in some jurisdictions.

Full Definition

A Guilty But Mentally Ill (GBMI) verdict is a legal finding available in some jurisdictions as an alternative to the traditional guilty or not guilty by reason of insanity verdicts. GBMI allows juries to find defendants criminally responsible while acknowledging that mental illness was present at the time of the offense. Defendants found GBMI serve their sentence in prison but are entitled to psychiatric treatment during incarceration. This verdict requires proof that the defendant committed the charged offense and was mentally ill at the time, but retains criminal responsibility. Critics argue GBMI verdicts may deny appropriate treatment and fail to address the relationship between mental illness and criminal behavior. The availability and criteria for GBMI verdicts vary significantly among jurisdictions that recognize this option.

Usage

Usage note: Spell out 'Guilty But Mentally Ill' on first reference; availability varies by jurisdiction.
