People v. Chiu

Chiu (defendant) participated in a gang-related brawl during which his associate Che killed Treadway; the jury was instructed it could convict Chiu of first-degree murder either through direct aiding and abetting of the murder, or under the natural and probable consequences doctrine (that Treadway's death was a foreseeable consequence of the assault Chiu helped commit), and found Chiu guilty of first-degree murder. The court of appeal reversed based on the jury instructions, and the state appealed.
