Matthew Cox was convicted pursuant to Iowa Code sections 709.1, 709.3(2), and 709.4(2)(6) (2005) of one count of sex abuse in the second degree and one count of sex abuse in the third degree for sexually abusing his younger cousin. The State presented evidence of Cox’s prior sexual abuse of two other cousins. Cox appealed, asserting the district court erred by admitting the instances of sexual abuse against other victims pursuant to Iowa Code section 701.11 (2007). Admission of prior bad acts solely to show a general propensity instead of a legitimate issue violates the due process clause of the Iowa Constitution. Because Cox’s prior bad acts with different victims are not relevant to a legitimate issue, section 701.11 is unconstitutional as applied to the facts of this case and we reverse.
I. Background Facts and Prior Proceedings.
Fourteen-year old J.M. accused her cousin Matthew Cox of fondling her on several occasions beginning when she was between four and six years old in about 1996-1998 and raping her beginning when she was a pre-teen in about 2003. According to J.M., most of these incidents took place at her grandmother’s house, where Cox lived. The State charged Cox with sexual abuse in the second degree for acts between January 1, 2003, and October 31, 2005, and later added a charge of sexual abuse in the third degree for acts after J.M. turned twelve.
At trial, T.C. and A.L., two of Cox’s other cousins, testified to prior sexual contact with Cox. T.C., a female, described two occasions when Cox forcibly fondled her, once at her grandmother’s house when she was ten, in about 1998, and once in a car when she was thirteen, in about 2001. A.L., a male and J.M.’s half-brother, described a pattern of abuse that began with inappropriate touching and forced oral sex when he was around age six, in about 1992, and escalated to incidents during which Cox forcibly performed anal intercourse with him. A.L. testified some of these alleged acts took place at his grandmother’s house.
Charges had been filed jointly based on Cox’s alleged abuse of A.L., but these charges were severed from those relating to J.M. prior to trial. 1 Cox then filed a motion in limine seeking to exclude prior-bad-acts evidence under Iowa Rules of Evidence 5.404(6) and 5.403. The State asserted such evidence was admissible under Iowa Code section 701.11. Cox argued that section 701.11 only applies to evidence of other sexual abuse with the same victim and application of section 701.11 here would be unconstitutional under the Iowa Constitution.
The State argued the prior acts of sexual abuse should be admitted under section 701.11 because of “common threads” in the testimony: all of the alleged victims were cousins of the defendant, all were abused as children or young adults, and all testi *760 fied to some abuse at the grandmother’s house. The State also argued the evidence showed the “defendant’s MO” and “a pattern of behavior,” making it admissible even under rule 5.404(6).
Ruling in favor of the State, the court concluded the evidence was admissible under section 701.11 because “the Legislature found it necessary in sexual abuse cases to make an exception. [The statute] doesn’t limit it to other sexual abuse against the same victim.” The court found the evidence relevant and also found the probative value of the evidence outweighed the prejudicial effect because of the arguments put forth by the State, including “the similarities,” and because the testimony “bolsters [J.M.’s] credibility as to ... her recitation as to the events as occurred.”
The district court ordered the State to lay the foundation for these witnesses outside the presence of the jury and again determined the testimony was admissible. The court gave a limiting jury instruction that “[e]vidence of another offense for which a defendant is not on trial does not mean that the defendant is guilty of the charges for which he is on trial.” The jury returned a guilty verdict, and Cox appealed.
II. Scope of Review.
We review a district court’s evi-dentiary rulings regarding the admission of prior bad acts for abuse of discretion.
State v. Parker,
III. Merits.
A. Prior Bad Acts Evidence. Cox asserts the district court erred by admitting evidence of his prior acts of sexual abuse under Iowa Code section 701.11. Cox argues if section 701.11 is read to allow prior bad acts against individuals other than the victim, it violates the due process clause of the Iowa Constitution. '
Under Iowa Rule of Evidence 5.404(6), “[e]vidence of other crimes, wrongs, or acts is not admissible to prove the character of a person in order to show that the person acted in conformity therewith.” Iowa R. Evid. 5.404(6). Therefore, such evidence “is not admissible to demonstrate the defendant has a criminal disposition and was thus more likely to have committed the crime in question.”
State v. Reynolds,
“is founded not on a belief that the evidence is irrelevant, but rather on a fear that juries will tend to give it excessive weight, and on a fundamental sense that no one should be convicted of a crime based on his or her previous misdeeds.”
State v. Sullivan,
However, prior bad acts are admissible if offered for the purpose of establishing “motive, opportunity, intent, preparation, plan, knowledge, identity, or absence of mistake or accident.” Iowa R. Evid. 5.404(6). “The purposes listed in [rule
*761
5.404(6) ] are not exclusive.”
State v. Plaster,
Iowa Code section 701.11 applies specifically to prior acts of sexual abuse and provides:
In a criminal prosecution in which a defendant has been charged with sexual abuse, evidence of the defendant’s commission of another sexual abuse is admissible and may be considered for its bearing on any matter for which the evidence is relevant. This evidence, though relevant, may be excluded if the probative value of the evidence is substantially outweighed by the danger of unfair prejudice, confusion of the issues, or misleading the jury, or by considerations of undue delay, waste of time, or needless presentation of cumulative evidence. This evidence is not admissible unless the state presents clear proof of the commission of the prior act of sexual abuse.
Iowa Code § 701.11(1). Section 701.11 appears to allow introduction of prior sexual abuse without limiting such evidence to the specific categories in Iowa Rule of Evidence 5.404(6): “motive, opportunity, intent, preparation, plan, knowledge, identity, or absence of mistake or accident.”
B. Constitutionality of Iowa Code Section 701.11. Cox argues Iowa Code section 701.11 violates the due process clause of the Iowa Constitution by allowing a defendant to be tried and convicted based on a general propensity instead of the charged offense.
2
Article I, section 9 of the Iowa Constitution guarantees that “no person shall be deprived of life, liberty, or property without due process of law.” Iowa Const. art. I, § 9. Although in the past we have interpreted the United States and Iowa Constitutions “in a similar fashion,”
State v. Seering,
In
State v. Reyes,
The holding in Reyes was limited to prior incidents involving the same victim. Id. at 102 n. 1. Reyes expressly declined to address situations involving a different victim. As stated in a footnote, “[w]e express no view regarding the constitutionality of Iowa Code section 701.11 where the prior acts of sexual abuse involve persons other than the current alleged victim.” Id. Today, we address the issue purposefully left unanswered in Reyes: whether admitting a defendant’s other acts of sexual abuse with a different victim violates due process. We hold the Iowa Constitution prohibits admission of prior bad acts evidence involving a different victim when admitted solely for the purpose of demonstrating propensity. Instead, the evidence must be relevant to a “legitimate issue.”
The United States Supreme Court has not reached, and instead has expressly reserved, the question of whether a state law admitting propensity evidence violates the Federal Due Process Clause.
Estelle v. McGuire,
Courts that follow the common-law tradition almost unanimously have come to disallow resort by the prosecution to any kind of evidence of a defendant’s evil character to establish a probability of his guilt.... The inquiry is not rejected because character is irrelevant; on the contrary, it is said to weigh too much with the jury and to so overper-suade them as to prejudge one with a bad general record and deny him a fair opportunity to defend against a particular charge.
Michelson v. United States,
The Federal Rules of Evidence previously referred to prior bad acts only in section 404(b), a provision similar to Iowa Rule of Evidence 5.404(6), which prohibited introduction of prior bad acts except in certain circumstances. Fed.R.Evid. 404(b). In 1994, Congress expanded the scope of admissible evidence by enacting Federal Rules of Evidence 413 and 414. *763 Similar to Iowa Code section 701.11, Federal Rule of Evidence 413(a) provides:
In a criminal case in which the defendant is accused of an offense of sexual assault, evidence of the defendant’s commission of another offense or offenses of sexual assault is admissible, and may be considered for its bearing on any matter to which it is relevant.
Fed.R.Evid. 413(a). Rule 414 applies to child molestation cases and permits evidence of the, defendant’s commission of other offenses of child molestation. Fed. R.Evid. 414(a). ■ The United States Supreme Court has not addressed the constitutionality of these rules.
3
However, federal courts have generally upheld the admission of evidence under rules 413 and 414.
See, e.g., United States v. Castillo,
In
United States v. Enjady,
Similarly, in
United States v. LeMay,
State courts have also confronted statutes similar to Iowa Code section 701.11. Most courts have followed the federal courts’ lead and held the balancing tests in the state equivalents of Federal Rule of Evidence 403 maintain the constitutionality of statutes admitting evidence of prior sexual offenses.
See, e.g., People v. Falsetta,
The Supreme Court of Missouri, however, has declared a law similar to Iowa Code section 701.11 unconstitutional.
See State v. Ellison,
When we evaluate the constitutionality of rules of evidence based on due process considerations, “the traditional approach-has been to invalidate an evidentiary rule only if it ‘violates those “fundamental conceptions of justice which lie at the base of our civil and political institutions,” which define “the community’s sense of fair play and decency.” ’ ”
Reyes,
The general rule prohibiting propensity evidence was firmly established in Iowa courts at common law.
See State v. Vance,
[pjroof of them only tended to prejudice the defendants with the jurors.... However depraved in character, and however full of crime [the defendants’] past lives may have been, the defendants were entitled to be tried upon competent evidence, and only for the offense charged.
Boyd v. United States,
Although historical practice generally excluded propensity evidence, “[t]he historical practice with respect to the admissibility of prior sexual acts is ambiguous at best.”
Reyes,
This court traced the history of a “lewd disposition” exception in Iowa in
State v. Cott,
[EJvidence tending to prove a lewd disposition of the defendant charged with lascivious acts with a minor was originally considered relevant only insofar as it showed his intent solely toward the prosecuting witness. Almost imperceptibly, the lewd disposition exception was overextended to permit evidence of the defendant’s acts with other victims. First, in [State v. Schlak,253 Iowa 113 , 116,111 N.W.2d 289 , 291 (1961)], it crept in as a synonym for motive. Then, in [State v. Maestas,224 N.W.2d 248 , 250-51 (Iowa 1974) ], it was used as an alternative rationale to the common scheme exception. However, proving lewd disposition has never been the sole purpose for which this court has approved the admission of testimony concerning- prior acts with persons other than the prosecutrix.
Id.
(emphasis added). Instead of relying solely on' a “lewd disposition” exception, when faced with prior sexual offenses towards one other than the victim, this court has typically required the challenged evidence to be “ ‘relevant and material to some legitimate issue other than a general propensity to , commit wrongful acts.’ ”
State v. Casady,
This court did allow admission of a prior sexual offense against an individual other than the particular victim without tying it to a legitimate issue other than general propensity in
State v. Spaulding,
313
*766
N.W.2d 878, 881 (1981). In
Spaulding,,
the court held testimony by the victim’s sister regarding an incident of sexual abuse could be admitted.
Id.
This court referenced a quotation from a renowned treatise stating: “ ‘[Cjertain unnatural sex crimes are in themselves so unusual and distinctive that any previous such acts by the accused with anyone are strongly probative of like acts upon the occasion involved in the charge.’ ”
Spaulding,
Notably, after
Spaulding,
this court continued to identify a legitimate and independent issue on which to base admission of prior sexual offenses towards one other than the particular victim.
See Bayles,
Case law recognizes deep concerns over admission of propensity evidence, including prior sexual abuse against a victim other than the one involved in the charged conduct; however, we must determine whether those concerns are rooted in constitutional protections or simply an example of the court’s supervisory authority over evi-dentiary rules. As noted above, an eviden-tiary rule violates due process if it “ ‘violates those “fundamental conceptions of justice which he at the base of our civil and political institutions,” which define “the community’s sense of fair play and decency.” ’ ”
Reyes,
In
Enjady,
the Tenth Circuit summarized the due process arguments against Federal Rule of Evidence 413:
5
(1) the ban against propensity evidence has been honored by the courts for a long period of time, (2) such evidence creates a presumption of guilt undermining the prosecution’s burden, and (3) the evidence licenses the jury to punish a defendant for past acts which erodes the fundamental presumption of innocence.
Enjady,
While this Court has never held that the use of prior convictions to show nothing more than a disposition to commit crime would violate the Due Process Clause of the Fourteenth Amendment, our decisions exercising supervisory power over criminal trials in federal courts, as well as decisions by courts of appeals and of state courts, suggest that evidence of prior crimes introduced for no purpose other than to show criminal disposition would violate the Due Process Clause. Evidence of prior convictions has been forbidden because it jeopardizes the presumption of innocence of the crime currently charged.
Spencer v. Texas,
“‘there are few principles of-American criminal jurisprudence more universally accepted than the rule that evidence which tends to show that the accused committed another crime independent of that for which he is on trial, even one of the same type, is inadmissible.’ ”
Hurst v. State,
Iowa courts similarly ground the rejection of propensity evidence on “fundamental” concerns of fairness and the presumption of innocence. The policy against admissibility of general propensity evidence stems from “ ‘a fundamental sense that no one should be convicted of a crime based on his or her previous misdeeds.’ ”
Sullivan,
This court has also applied the reasoning that general propensity evidence is fundamentally unfair in the context of pri- or sexual abuse involving a different victim. In Cott, this court based its rejection of the “lewd disposition exception” on concerns of “unfairness.” As the court explained:
A focus on the criminal or aberrant disposition of the defendant with regard to various victims is exactly the sort of prejudice which the general rule seeks to avoid. By creating an exception of this kind, we would seriously erode the impact of the general rule, proscribing evidence of prior criminal conduct, in the context of sex crimes. The resultant unfairness to those accused of sex crimes is self-evident.
Cott,
Unlike the other purposes for other-crimes evidence, the sex-crime exception flaunts the general prohibition of evidence whose only purpose is to invite the inference that a defendant who com *768 mitted a previous crime is disposed toward committing crimes, and therefore is more likely to have committed the one at bar.
1 Kenneth S. Broun, McCormick on Evidence § 190, at 764 (6th ed. 2006) [hereinafter McCormick on Evidence ].
Based on ■ Iowa’s history and the legal reasoning for prohibiting admission of propensity evidence but of fundamental conceptions of fairness, we hold the Iowa Constitution prohibits admission of prior bad acts evidence based solely on general propensity. Such evidence may, however, be admitted as proof for any legitimate issues for which prior bad acts are relevant and necessary, including those listed in rule 5.404(6) and developed through Iowa case law. For example, after this court held in
Mitchell I
that evidence of prior sexual abuse of two other victims could not be admitted to demonstrate witness credibility because it was “ ‘ “merely a synonym for propensity,” ’ ”
see Mitchell I,
Our holding today is consistent with
Reyes.
Prior bad acts evidencé involving the same victim “has relevance on the underlying criminal charge because it shows the nature of the relationship between the alleged perpetrator and the victim.” Re
yes,
Unlike the federal courts that have considered this issue, we do not believe evidence of prior -bad acts can be admitted for the sole purpose of showing general propensity even if a trial judge considers the balancing test found in Iowa Code section 701.11.
See, e.g., LeMay,
Iowa Code section 701.11 violates the due process clause of the Iowa Constitution as applied in this case because it permits admission of prior bad acts against an individual other than the victim in the case to demonstrate general propensity.
See War Eagle Vill. Apartments v. Plummer,
C. Applicability to Cox. Here, the evidence of prior sexual abuse was improperly admitted into evidence as propensity evidence. However, we must decide whether it could be admitted for a “legitimate issue.” If a legitimate issue can be identified, we then consider whether the evidence is unfairly prejudicial compared with the probative value of the legitimate. issue. We address these ■ issues because we do not reverse when evidence was improperly admitted based on one particular reason if the evidence could be • admitted for other reasons on retrial. ■
DeVoss v. State,
Before the trial court, the State suggested the evidence would be admissible to show “proof of motive, opportunity, intent, preparation, plan and some of the other purposes for which prior bad acts are admissible.” Therefore, to determine whether these prior bad acts were admissible, we must consider whether they were relevant to one of these legitimate issues other than propensity.
1. Opportunity, preparation. Before the district court, the State listed the exceptions found in rule 5.404(6) and “some other purposes for which prior bad acts are "admissible.” It does not appear that opportunity and preparation were legitimate issues in "this particular case. The testimony of A.L. and T.C. does not establish opportunity or preparation for the offense allegedly committed against J.M. because A.L. and T.C. testified regarding separate incidents at separate times.
2. Common scheme or plan. The State argued to the trial court that because the victims of the charged and uncharged conduct were all cousins, and some of the abuse took place at the same location and stage in their lives, it demonstrated a common scheme or plan. The State argued that although this was not a “signature crime,” it shows a “pattern of behavior.”
The test for a common scheme or plan is not simply a pattern of prior bad acts. “Common scheme or plan means more than the commission of two similar crimes by the same person.”.
State v. Wright,
In
Cott,
this court addressed whether sexual abuse of someone other than the victim of the charged crime could be considered a common scheme or system of criminal activity. The court rejected that argument because “[t]he fact that defendant committed crimes of the same nature against the two girls is insufficient to bring the testimony within that exception.”
Cott,
Here there has been no suggestion of a common scheme or plan that would necessitate the admissibility of A.L.’s and T.C.’s testimony to complete the story of the crime against J.M. The evidence demonstrates Cox essentially committed crimes of availability against his cousins, which demonstrates nothing more than propensity. J.M., T.C., and A.L. all testified to a pattern of abuse they suffered as children and young adults, but none of the incidents of abuse against T.C. or A.L. are alleged to have occurred on the same day or connected to an incident of abuse against J.M. None of the testimony by T.C. or A.L. was necessary to “complete the story” of the crimes against J.M. or to provide the “ ‘immediate context of happenings near in time and place.’ ”
Id.
(quoting
Wright,
3.
Modus operandi.
Although the State stated before the district court that the additional evidence was “not exactly, I guess, what we would refer to as a signature crime,” we consider the modus operandi exception. “Modus operandi is ‘ “a distinct pattern or method of procedure thought to be characteristic of an individual criminal ] and habitually followed by him.” ’ ”
Plaster,
We have also used modus operandi to admit evidence for the legitimate issue of countering a defense of consent in a sexual assault case.
Plaster,
4.
Motive, intent.
There are numerous ways in which prior sexual abuse of one other than the victim may become relevant to motive or intent; however, there is no argument that they are present in this case. For example, prior bad acts may be relevant to demonstrate motive or intent when a defendant claims touching was accidental.
Cf. State v. Elston,
D. Harmless Error. Because we hold the testimony of A.L. and T.C. was improperly admitted at trial, we consider whether the error was harmless. To establish harmless error when a defendant’s constitutional rights have been violated, the State must prove beyond a reasonable doubt that the error complained of did not contribute to the verdict obtained.
State v. Walls,
Although it does not appear the testimony of A.L. and T.C. was relevant to any “legitimate issue” and therefore was not appropriately admitted, we express no opinion regarding whether the evidence may become relevant to a legitimate issue and be admissible on retrial. In
Mitchell I,
this court held that evidence of prior sex
*772
abuse of individuals other than the victim of the charged crime could not be admitted under the theory that it bolstered the witness’s credibility or a lewd disposition exception.
Mitchell I,
IV. Conclusion.
Admitting evidence of a defendant’s sexual abuse of other victims under Iowa Code section 701.11 based only on its value as general propensity evidence violates the due process clause of the Iowa Constitution. Therefore, it was improper for individuals other than the victim J.M. to testify regarding prior acts of sexual abuse where there was no legitimate issue other than propensity to which they were relevant.
JUDGMENT REVERSED AND CASE REMANDED.
Notes
. Cox was tried separately for offenses against A.L. and convicted of sexual abuse in the second degree.
. The State argues this constitutional claim is not preserved because it was not raised below in the district court. We disagree. Before the district court, defense trial counsel argued that: (1) the State was seeking to admit the prior bad acts evidence as propensity evidence to suggest "he did it to others; therefore, he did it here;” (2) Iowa Code section 701.11 should be interpreted to only apply to allegations of prior sex abuse against the same victim; and (3) section 701.11 violates due process because it is overly broad and vague. We hold that counsel's arguments were sufficient to preserve this issue for appellate review.
. Federal Rules 413 and 414 were controversial when enacted:
[T]he members of two committees, consisting of 40 persons in all, and appointed by the Judicial Conference of the United States to examine Fed.R.Evid. 413 before its passage, all but unanimously urged that Congress not adopt the rule because of deep concerns about its fundamental fairness.
United States v. Mound,
. One clause provides that “no person shall be prosecuted criminally for felony or misdemeanor otherwise than by indictment or information.” Mo. Const, art. 1, § 17. The other provides that “in criminal prosecutions the accused shall have the right ... to demand the nature and cause of the accusation.” Mo. Const, art. 1, § 18(a).
. Scholars and commentators have argued that admitting propensity evidence in sexual abuse or assault cases deprives a defendant of his constitutional right to a fair trial. See, e.g., William E. Marcantel, Protecting the Predator or the Prey? The Missouri Supreme Court’s Refusal to Allow Past Sexual Misconduct as Propensity Evidence, 74 Mo. L. Rev. 211, 230-33 (2009) (arguing the U.S. Supreme Court should follow the Missouri court's reasoning in rejecting propensity evidence); Jason L.
