Guilty but Mentally Ill Law and Legal Definition

Guilty but Mentally Ill or GBMI is a verdict available in some jurisdictions in cases involving an insanity defense. In such cases, the defendant eventhough found guilty is committed to a mental hospital rather than imprisoned, if an examination shows a need for psychiatric treatment. The GBMI verdict is available as an alternative to, rather than in lieu of, a not guilty by reason of insanity verdict. In the U.S. Michigan was the first state to create a GBMI verdict.
