clear-proof requirement in Iowa

2026Clear proof cannot be established by mere speculation or hearsay but “[t]estimony of credible witnesses can satisfy the clear-proof requirement.” Thoren, 970 N.W.3d at 262 (alteration in original) (quoting State v. Putman, 848 N.W.2d 1, 9 (Iowa 2014)).

2025Mere speculation or hearsay is not enough, but “[t]estimony of credible witnesses can satisfy the clear-proof requirement.” Finally, the court must consider whether the evidence’s “probative value is substantially outweighed by the danger of unfair prejudice to the defendant.” State v. Thoren, 970 N.W.2d 611 , 626 (Iowa 2022) (alteration in original) (citations omitted) (first quoting State v. Putman, 848 N.W.2d 1, 9 (Iowa 2014); and then quoting State v. Sullivan, 679 N.W.2d 19, 25 (Iowa 2004)).

2026See State v. Jones, 464 N.W.2d 241, 243 (Iowa 1990) (“Because the victim’s testimony constituted clear proof of the prior instances of sexual abuse, the district court did not abuse its discretion when it refused to exclude the testimony.”).

2017Each of the cases originates with State v. Jones, 464 N.W.2d 241, 243 (Iowa 1990), in which the court stated a victim’s testimony about “prior instances of sexual abuse” can satisfy the clear proof requirement if the testimony is “sufficiency credible and detailed.” To hold otherwise would allow a not credible witness, as is the case here, bolster her credibility by bootstrapping a prior alleged incident of abuse to the offense conduct at issue.

2014In State v. Johnson, we observed that, in addition to the relevancy requirement, “[p]roof of the other offenses must be clear” before explaining the trial court still must balance evidence’s probative value against its prejudicial effect. 224 N.W.2d 617, 620, 621 (Iowa 1974); see also Rodriguez, 636 N.W.2d at 240 (“Since our decision in [State v.] Wade, [ 467 N.W.2d 283 (Iowa 1991)], we have stated that there must be ‘clear proof’ that the defendant committed the prior bad acts.”); State v. Brown, 569 N.W.2d 113, 117 (Iowa 1997) (noting that “[i]n at least some cases we have added as a final c

2019The clear proof standard is satisfied if the evidence is sufficient “to ‘prevent the jury from engaging in speculation or drawing inferences based on mere suspicion.’” Id. (quoting State v. Taylor, 689 N.W.2d 116, 130 (Iowa 2004)).

2023So, while a number of the contested statements cannot 6Timely Mission challenges relevance in its reply brief, but “we have long held that an issue cannot be asserted for the first time in a reply brief.” Young v. Gregg, 480 N.W.2d 75, 78 (Iowa 1992). 22 meet the clear-proof requirement, Beck’s testimony about what she saw herself can.

2023We move, then, to the four-part test to determine “whether the evidence’s ‘probative value is substantially outweighed by the danger of unfair prejudice to the defendant.’” Id. (citation omitted).

2023But first, we note that “Iowa recognizes a special exception in sex abuse cases which permits use of prior acts ‘to show a passion or propensity for illicit sexual relations with the particular person concerned in the crime on trial.’” State v. Schaffer, 524 N.W.2d 453, 456 (Iowa Ct. App. 1994) (quoting State v. Spaulding, 313 N.W.2d 878 , 880–81 (Iowa 1981) (collecting cases recognizing the special exception).

2022The fourth element, causation, requires a heightened clear-proof standard which “ensures the other factors really mattered to the end result.” Id.; see also In re Est. of Davenport, 346 N.W.2d 530, 532 (Iowa 1984) (“It is not sufficient that persuasion alone was asserted against the testator.

2021See Putnam, 848 N.W.2d at 9 (noting that clear proof does not require the bad acts to be established beyond a reasonable doubt or corroborated by other evidence); State v. Zeliadt, 541 N.W.2d 558, 561 (Iowa Ct. App. 1995) (finding testimony from a single witness clear proof of the prior act).

2017See State v. Richards, 879 N.W.2d 140, 152 (Iowa 2016) (stating a victim’s testimony is enough to establish “clear proof” and the testimony need not be corroborated).
