From the opinions
“The jury’s verdict that McElrath was not guilty of malice murder by reason of insanity constituted an acquittal for double jeopardy purposes.”
What's next
The case returns to Georgia courts, which must apply the Supreme Court’s decision. Georgia cannot pursue a second prosecution of McElrath for the acquitted malice-murder charge.
Why it matters
For example, a defendant acquitted by reason of insanity on one count cannot be tried again on that count because of a conflicting verdict on another count.
