McElrath v. Georgia

Damian McElrath was charged in Georgia with malice murder, felony murder, and aggravated assault after stabbing his mother, Diane McElrath, during a psychotic episode in 2012. A jury found him not guilty by reason of insanity on malice murder but guilty but mentally ill on felony murder and aggravated assault. The Georgia Supreme Court held the verdicts were repugnant and ordered a new trial on all charges. The U.S. Supreme Court, in a unanimous opinion by Justice Ketanji Brown Jackson, held that the malice murder acquittal was an acquittal for double jeopardy purposes, regardless of any inconsistency, and could not be retried.

The U.S. Supreme Court reversed the Georgia Supreme Court, holding that the not-guilty-by-reason-of-insanity verdict on malice murder was an acquittal and retrial on that charge is barred by the Double Jeopardy Clause.

Whether the Double Jeopardy Clause permits retrial of a charge for which a jury returned a verdict of not guilty by reason of insanity when that verdict is inconsistent with guilty verdicts on other charges under Georgia law.

The decision reinforced constitutional protection against double jeopardy, limited states’ ability to overturn inconsistent jury acquittals, and provided clarity for defendants acquitted by reason of insanity. It may affect how Georgia and other states handle repugnant verdicts involving mental illness defenses.
