966 N.W.2d 641
Iowa2021Background
- Child victim S.V. reported contemporaneous sexual abuse by her grandfather Michael Montgomery and by a teenager in the household, L.V.; L.V. later admitted and was charged in delinquency proceedings.
- Montgomery made statements to police acknowledging instances where S.V. placed his hand on her groin; there was no physical or DNA evidence tying him to abuse.
- Before trial Montgomery sought to admit evidence (including expert testimony) that L.V. abused S.V. to (a) show an alternate source of the child’s sexual knowledge, (b) support a theory of contamination/misattribution of memories, and (c) impeach motive/bias; the district court excluded that evidence under Iowa Rule of Evidence 5.412 (rape shield).
- At trial the jury heard S.V.’s account of abuse by Montgomery but not about L.V.’s abuse; the jury acquitted on lascivious-acts charges (which require sexual gratification) but convicted on second-degree sexual abuse (which, per precedent, does not require sexual gratification).
- Montgomery sought a jury instruction requiring proof of sexual gratification and urged overruling State v. Pearson; the Iowa Supreme Court declined to overrule Pearson, but held the rape-shield exclusion of evidence about L.V. violated Montgomery’s constitutional rights and ordered a new trial.
Issues
| Issue | Plaintiff's Argument (State) | Defendant's Argument (Montgomery) | Held |
|---|---|---|---|
| Whether Pearson should be overruled to require sexual-gratification as an element of "sex act"/sexual abuse | Pearson is binding precedent; statute and practice justify the existing "sexual in nature" standard | Pearson is unworkable; sexual gratification should be an element to avoid convictions for non-sexual contact | Court declined to overrule Pearson; sexual abuse may be proven by "sexual in nature" contact without proof of sexual gratification |
| Whether the jury verdict (acquittal on lascivious acts but conviction on sexual abuse) is inconsistent | Not inconsistent because lascivious acts requires gratification and sexual abuse does not; offenses are not legal equivalents | Inconsistency requires reversal if both crimes require same mental element | Verdict not legally or logically inconsistent under Pearson; no reversal on that ground |
| Whether the trial court erred by refusing a supplemental instruction defining "sexual in nature" to require gratification | Instruction given tracked statute and Pearson; supplemental instruction would contradict Pearson | Jury should be told gratification is required to determine "sexual in nature" | Court properly refused the supplemental instruction because it would conflict with Pearson |
| Whether exclusion under Iowa R. Evid. 5.412 of evidence that L.V. also abused S.V. violated Montgomery's constitutional rights | Rule 5.412 bars prior-sexual-conduct evidence unless exception applies; probative value did not outweigh prejudice | Evidence was admissible under exceptions and Constitution to show alternate source of sexual knowledge, contamination, and bias/motive; expert and cross-examination were necessary | Exclusion violated the constitutional-rights exception to Rule 5.412; evidence should have been admitted; error was not harmless—new trial ordered |
