Summary
The Nebraska Supreme Court affirmed the Court of Appeals' reversal of a juvenile adjudication for first degree sexual assault. The court held that the State failed to prove beyond a reasonable doubt that the alleged victim's mental impairment was sufficiently severe to make him incapable of resisting or appraising the nature of the sexual conduct, and that the juvenile knew or should have known of that incapacity. The court also held that expert testimony is not required in every lack-of-capacity sexual assault case involving mental illness or impairment.

Questions Presented
- What standard of review applies to an insufficiency-of-the-evidence challenge in a juvenile adjudication?
- Whether lack of consent is an element of sexual assault under Neb. Rev. Stat. § 28-319(1)(b) when the victim is incapable of resisting or appraising the nature of the conduct.
- What severity of mental impairment must the State prove to establish lack-of-capacity sexual assault under § 28-319(1)(b)?
- Whether expert testimony is required in every prosecution for lack-of-capacity sexual assault based on mental illness or impairment.
- Whether the evidence proved beyond a reasonable doubt that D.F. lacked the capacity to consent and that K.M. knew or should have known of that incapacity.
Holdings
- Juvenile cases are reviewed de novo on the record, and the appellate court reaches its conclusions independently of the juvenile court's findings; the court disapproved In re Interest of McManaman to the extent it imported the adult criminal substantial-evidence standard into juvenile matters.
- A victim's lack of consent is not a separate element of sexual assault under § 28-319(1)(b) when the victim is incapable of resisting or appraising the nature of the conduct; however, the State must prove beyond a reasonable doubt that the victim lacked the capacity to consent and that the defendant knew or should have known of that incapacity.
- To prove lack-of-capacity sexual assault based on mental impairment under § 28-319(1)(b), the State must prove beyond a reasonable doubt that the impairment was so severe that the victim was mentally incapable of resisting or mentally incapable of appraising the nature of the sexual conduct.
- Expert testimony concerning a victim's mental incapacity may be probative and may be required in some factual situations, but it is not required in every case of lack-of-capacity sexual assault based on mental illness or impairment.
- The State failed to prove beyond a reasonable doubt that D.F. was incapable of resisting or appraising the nature of the sexual conduct, or that K.M. knew or should have known of such incapacity.
Key quotations
“We find this de novo standard of review to be most applicable to juvenile matters. As a result, we take this opportunity to disapprove of our holding in In re Interest of McManaman as it relates to importing into a juvenile matter the standard of review used in adult criminal proceedings.” (642-643)
“Thus, we hold that to prove a lack-of-capacity sexual assault on the basis of a mental impairment, under § 28-319(1)(b), the State must prove beyond a reasonable doubt that the victim’s impairment was so severe that he or she was “mentally . . . incapable of resisting” or “mentally . . . incapable of . . . appraising the nature of” the sexual conduct with the alleged perpetrator.” (646)
“As a result, we conclude that while expert testimony as to a victim’s mental incapacity may be probative, expert testimony is not required in every case of lack-of-capacity sexual assault based on the victim’s mental illness or impairment.” (648)
“The State bears the burden, when proving sexual assault based on the victim’s lack of capacity, that the victim actually lacked the capacity to consent. It has not done so here.” (649)
Factual background
K.M., age 13, was accused of sexually penetrating D.F., age 12, who had reportedly been diagnosed with Asperger syndrome. During a police interview, K.M. admitted that his penis may have penetrated D.F.'s anus and stated that D.F. had autism and did not know right from wrong. The State presented no testimony from D.F. and no specific evidence explaining D.F.'s diagnosis, the severity of his impairment, or its effect on his ability to resist or understand the sexual conduct. The juvenile court adjudicated K.M., but the Court of Appeals and Nebraska Supreme Court concluded that the evidence did not establish the victim's lack of capacity beyond a reasonable doubt.
Procedural history
The Separate Juvenile Court of Douglas County adjudicated K.M. under Neb. Rev. Stat. § 43-247(2), finding beyond a reasonable doubt that he committed conduct constituting first degree sexual assault under § 28-319(1)(b). The Nebraska Court of Appeals reversed for insufficient evidence that K.M. knew or should have known that the alleged victim was mentally or physically incapable of resisting or appraising the nature of the conduct. The Nebraska Supreme Court affirmed the Court of Appeals' reversal.
