State v. J. C. N.-V., 380 P.3d 248

A 13-year-old (Youth) was alleged to have participated intimately in a violent murder; the State petitioned to waive juvenile court jurisdiction so Youth could be tried as an adult for aggravated murder.
The juvenile court found Youth had "sufficient sophistication and maturity to appreciate the nature and quality of the conduct involved" and waived him to adult court; the Court of Appeals (en banc) affirmed.
Lower-court findings emphasized Youth’s admissions, purposeful participation, post-offense concealment, and coherent police interview; experts offered conflicting evaluations of Youth’s maturity and brain development.
State relied on a psychologist who concluded Youth was average for his age and understood his conduct was wrong; Youth presented neuroscientific and psychological evidence about adolescent immaturity and susceptibility to peer influence.
The central legal question concerned the meaning of ORS 419C.349(3) (incorporated into ORS 419C.352): whether the statute requires only criminal-capacity knowledge (physical nature and wrongfulness) or a more adult-like intellectual and emotional appreciation of the conduct.

Issue	Plaintiff's Argument (State)	Defendant's Argument (Youth)	Held
Meaning of ORS 419C.349(3): "sufficient sophistication and maturity to appreciate the nature and quality of the conduct"	Requires only basic criminal capacity: knowledge of the physical act and that it is wrong; a low threshold met by most normally-abled adolescents	Requires a higher, adult-like intellectual and emotional appreciation (deeper understanding of wrongfulness, consequences, empathy) beyond mere knowledge	Court held the statute requires a more demanding, adult-like appreciation (intellectual and emotional), not just criminal-capacity knowledge
Application to this waiver decision	Juvenile court’s findings that Youth knew the plan, participated, and feared punishment satisfy the statutory requirement	Those findings show only knowledge of the act and consequences, not adult-like appreciation; expert evidence of adolescent immaturity undermines waiver	The court reversed: juvenile court’s findings were insufficient under the correct standard and remanded for reconsideration under the proper test
