McElrath v. Georgia
The Supreme Court unanimously ruled that Georgia cannot retry Damian McElrath for murder, because the jury's 'not guilty by reason of insanity' verdict was a constitutional acquittal — final and unreviewable — regardless of whether it conflicted with the jury's other verdicts that day.
The decision makes clear that states cannot use their own procedural rules to erase an acquittal and give prosecutors a second chance at conviction, even when the jury's verdicts appear internally contradictory.
How it got here: Georgia trial and appellate courts rejected McElrath's double-jeopardy argument; the Georgia Supreme Court affirmed; McElrath asked the U.S. Supreme Court to step in and the Court agreed to hear it.
The Case in Depth
What happened
In 2012, Damian McElrath, an 18-year-old with schizophrenia, stabbed his adoptive mother to death, believing she had been poisoning him. Georgia charged him with malice murder, felony murder, and aggravated assault. At trial he raised an insanity defense. The jury returned a split verdict: not guilty by reason of insanity on malice murder, but guilty but mentally ill on the other two counts. Georgia's Supreme Court found the verdicts contradictory, wiped them all out under a state "repugnancy doctrine," and authorized a retrial on all charges.
The question before the Court
Can a state retry someone for murder after a jury found him not guilty by reason of insanity on that charge, simply because that verdict contradicted the jury's other findings in the same trial?
The Court's answer
No — Georgia cannot retry McElrath for malice murder. The jury's verdict of "not guilty by reason of insanity" on that charge was an acquittal under the Constitution's Double Jeopardy Clause, which bars the government from retrying someone after failing to secure a conviction. Whether an acquittal has occurred is a question of federal constitutional law, not state law — so Georgia could not use its own procedural "repugnancy doctrine" to declare the jury's verdict a nullity and restart the prosecution.
The Court also rejected Georgia's argument that the jury's seemingly contradictory findings gave courts valid grounds to look behind the acquittal and set it aside. Once a jury determines the prosecution has not proven its case, that verdict is final — courts may not speculate about why a jury acquitted, even when specific jury findings appear to explain the inconsistency.

Why it matters
Criminal defendants who receive any form of not-guilty verdict — including a not-guilty-by-reason-of-insanity finding — are protected from retrial on that charge. States cannot invoke local procedural doctrines to recharacterize an acquittal as legally void and restart the prosecution. This protection holds even when the same jury returned contradictory verdicts on related charges in the same trial.
What changes now
The Supreme Court's ruling bars Georgia from retrying McElrath on the malice-murder charge. The case returns to Georgia's courts, where they may address as a matter of state law what becomes of McElrath's vacated felony-murder conviction — the charge on which he had been sentenced to life imprisonment. The Double Jeopardy Clause question as to the felony-murder count was not before the Court and remains open on remand.
What this does not decide
The ruling does not address what happens when a trial judge refuses to accept inconsistent verdicts and sends the jury back to deliberate before any verdict is formally entered. Justice Alito's concurrence explicitly flags this: the decision says nothing about whether a not-guilty verdict that a trial judge declines to accept would also constitute a binding acquittal.
Concurrences and dissents
Concurrence — Justice Alito
Justice Alito joined the majority opinion in full but wrote separately to make clear he sees the holding as narrow. In his view, the case turns on the fact that the trial judge actually accepted and entered the not-guilty verdict — making it an unambiguous acquittal subject to appellate review. He emphasized that the decision says nothing about whether a trial judge who refuses to accept inconsistent verdicts and sends the jury back would similarly be blocked by double jeopardy, a question he viewed as still open.
How the Court got there
The legal reasoning, step by step
- The Court began with the Double Jeopardy Clause of the Fifth Amendment, which bars the government from trying someone twice for the same offense. The key threshold question was what counts as an 'acquittal' — the Court's answer: any ruling by which a factfinder concludes that the prosecution's proof was not enough to establish criminal guilt, regardless of what the ruling is called.
- The Court applied a substance-over-labels rule: whether an acquittal occurred for Double Jeopardy purposes is a matter of federal constitutional law, not state law. A state's own characterization of a verdict — including declaring it void — does not bind the federal constitutional analysis. Courts look to what the verdict actually did, not what a state court later calls it.
- The jury's 'not guilty by reason of insanity' verdict on the malice-murder count was, in substance, a determination that the prosecution failed to prove McElrath was criminally responsible. Under Georgia law, an insanity verdict specifically means the defendant 'shall not be found guilty.' That is a classic acquittal, and Georgia itself conceded the verdict would have been valid if it had been the only count.
- Georgia argued its 'repugnancy doctrine' — which lets courts void mutually contradictory verdicts — meant no valid verdict was ever entered, so no acquittal ever existed. The Court rejected this: a state cannot use its own procedural rules to nullify what is, in substance, a constitutional acquittal. Federal double jeopardy law recognizes the acquittal regardless of the state's label.
- Georgia also argued that the jury's specific findings about the defendant's different mental states at the time of the crime gave courts enough information to identify and correct the inconsistency — unlike a general verdict where the jury's reasoning is opaque. The Court rejected this too: once an acquittal has been rendered, courts are forbidden from speculating about why the jury decided as it did, even when specific findings appear to offer a factual explanation. Allowing courts to peer behind a not-guilty verdict based on specific findings would let judges override the jury's unreviewable power to acquit.
