Notes of Advisory Committee on Proposed Rules

Subdivision (a). This subdivision deals with the basic question whether character evidence should be admitted. Once the admissibility of character evidence in some form is established under this rule, reference must then be made to Rule 405, which follows, in order to determine the appropriate method of proof. If the character is that of a witness, see Rules 608 and 610 for methods of proof.

Character questions arise in two fundamentally different ways. (1) Character may itself be an element of a crime, claim, or defense. A situation of this kind is commonly referred to as "character in issue." Illustrations are: the chastity of the victim under a statute specifying her chastity as an element of the crime of seduction, or the competency of the driver in an action for negligently entrusting a motor vehicle to an incompetent driver. No problem of the general relevancy of character evidence is involved, and the present rule therefore has no provision on the subject. The only question relates to allowable methods of proof, as to which see Rule 405, immediately following. (2) Character evidence is susceptible of being used for the purpose of suggesting an inference that the person acted on the occasion in question consistently with his character. This use of character is often described as "circumstantial." Illustrations are: evidence of a violent disposition to prove that the person was the aggressor in an affray, or evidence of honesty in disproof of a charge of theft. This circumstantial use of character evidence raises questions of relevancy as well as questions of allowable methods of proof.

In most jurisdictions today, the circumstantial use of character is rejected but with important exceptions: (1) an accused may introduce pertinent evidence of good character (often misleadingly described as "putting his character in issue"), in which event the prosecution may rebut with evidence of bad character; (2) an accused may introduce pertinent evidence of the character of the victim, as in support of a claim of self-defense to a charge of homicide or consent in a case of rape, and the prosecution may introduce similar evidence in rebuttal of the character evidence, or, in a homicide case, to rebut a claim that deceased was the first aggressor, however proved; and (3) the character of a witness may be gone into as bearing on his credibility. McCormick §§155–161. This pattern is incorporated in the rule. While its basis lies more in history and experience than in logic as underlying justification can fairly be found in terms of the relative presence and absence of prejudice in the various situations. Falknor, Extrinsic Policies Affecting Admissibility, 10 Rutger, L.Rev. 574, 584 (1956); McCormick §157. In any event, the criminal rule is so deeply imbedded in our jurisprudence as to assume almost constitutional proportions and to override doubts of the basic relevancy of the evidence.

The limitation to pertinent traits of character, rather than character generally, in paragraphs (1) and (2) is in accordance with the prevailing view. McCormick §158, p. 334. A similar provision in Rule 608, to which reference is made in paragraph (3), limits character evidence respecting witnesses to the trait of truthfulness or untruthfulness.

The argument is made that circumstantial use of character ought to be allowed in civil cases to the same extent as in criminal cases, i.e. evidence of good (nonprejudicial) character would be admissible in the first instance, subject to rebuttal by evidence of bad character. Falknor, Extrinsic Policies Affecting Admissibility, 10 Rutgers L.Rev. 574, 581–583 (1956); Tentative Recommendation and a Study Relating to the Uniform Rules of Evidence (Art. VI. Extrinsic Policies Affecting Admissibility), Cal. Law Revision Comm'n, Rep., Rec. & Studies, 657–658 (1964). Uniform Rule 47 goes farther, in that it assumes that character evidence in general satisfies the conditions of relevancy, except as provided in Uniform Rule 48. The difficulty with expanding the use of character evidence in civil cases is set forth by the California Law Revision Commission in its ultimate rejection of Uniform Rule 47, Id., 615:

"Character evidence is of slight probative value and may be very prejudicial. It tends to distract the trier of fact from the main question of what actually happened on the particular occasion. It subtly permits the trier of fact to reward the good man to punish the bad man because of their respective characters despite what the evidence in the case shows actually happened."

Much of the force of the position of those favoring greater use of character evidence in civil cases is dissipated by their support of Uniform Rule 48 which excludes the evidence in negligence cases, where it could be expected to achieve its maximum usefulness. Moreover, expanding concepts of "character," which seem of necessity to extend into such areas as psychiatric evaluation and psychological testing, coupled with expanded admissibility, would open up such vistas of mental examinations as caused the Court concern in Schlagenhauf v. Holder, 379 U.S. 104, 85 S.Ct. 234, 13 L.Ed.2d 152 (1964). It is believed that those espousing change have not met the burden of persuasion.

Subdivision (b) deals with a specialized but important application of the general rule excluding circumstantial use of character evidence. Consistently with that rule, evidence of other crimes, wrongs, or acts is not admissible to prove character as a basis for suggesting the inference that conduct on a particular occasion was in conformity with it. However, the evidence may be offered for another purpose, such as proof of motive, opportunity, and so on, which does not fall within the prohibition. In this situation the rule does not require that the evidence be excluded. No mechanical solution is offered. The determination must be made whether the danger of undue prejudice outweighs the probative value of the evidence in view of the availability of other means of proof and other factors appropriate for making decisions of this kind under Rule 403. Slough and Knightly, Other Vices, Other Crimes, 41 Iowa L.Rev. 325 (1956).

Notes of Committee on the Judiciary, House Report No. 93–650

The second sentence of Rule 404(b) as submitted to the Congress began with the words "This subdivision does not exclude the evidence when offered". The Committee amended this language to read "It may, however, be admissible", the words used in the 1971 Advisory Committee draft, on the ground that this formulation properly placed greater emphasis on admissibility than did the final Court version.

Notes of Committee on the Judiciary, Senate Report No. 93–1277

This rule provides that evidence of other crimes, wrongs, or acts is not admissible to prove character but may be admissible for other specified purposes such as proof of motive.

Although your committee sees no necessity in amending the rule itself, it anticipates that the use of the discretionary word "may" with respect to the admissibility of evidence of crimes, wrongs, or acts is not intended to confer any arbitrary discretion on the trial judge. Rather, it is anticipated that with respect to permissible uses for such evidence, the trial judge may exclude it only on the basis of those considerations set forth in Rule 403, i.e. prejudice, confusion or waste of time.

Notes of Advisory Committee on Rules—1987 Amendment

The amendments are technical. No substantive change is intended.

Notes of Advisory Committee on Rules—1991 Amendment

Rule 404(b) has emerged as one of the most cited Rules in the Rules of Evidence. And in many criminal cases evidence of an accused's extrinsic acts is viewed as an important asset in the prosecution's case against an accused. Although there are a few reported decisions on use of such evidence by the defense, see, e.g., United States v. McClure, 546 F.2nd 670 (5th Cir. 1990) (acts of informant offered in entrapment defense), the overwhelming number of cases involve introduction of that evidence by the prosecution.

The amendment to Rule 404(b) adds a pretrial notice requirement in criminal cases and is intended to reduce surprise and promote early resolution on the issue of admissibility. The notice requirement thus places Rule 404(b) in the mainstream with notice and disclosure provisions in other rules of evidence. See, e.g., Rule 412 (written motion of intent to offer evidence under rule), Rule 609 (written notice of intent to offer conviction older than 10 years), Rule 803(24) and 804(b)(5) (notice of intent to use residual hearsay exceptions).

The Rule expects that counsel for both the defense and the prosecution will submit the necessary request and information in a reasonable and timely fashion. Other than requiring pretrial notice, no specific time limits are stated in recognition that what constitutes a reasonable request or disclosure will depend largely on the circumstances of each case. Compare Fla. Stat. Ann §90.404(2)(b) (notice must be given at least 10 days before trial) with Tex.R.Evid. 404(b) (no time limit).

Likewise, no specific form of notice is required. The Committee considered and rejected a requirement that the notice satisfy the particularity requirements normally required of language used in a charging instrument. Cf. Fla. Stat. Ann §90.404(2)(b) (written disclosure must describe uncharged misconduct with particularity required of an indictment or information). Instead, the Committee opted for a generalized notice provision which requires the prosecution to apprise the defense of the general nature of the evidence of extrinsic acts. The Committee does not intend that the amendment will supercede other rules of admissibility or disclosure, such as the Jencks Act, 18 U.S.C. §3500, et seq. nor require the prosecution to disclose directly or indirectly the names and addresses of its witnesses, something it is currently not required to do under Federal Rule of Criminal Procedure 16.

The amendment requires the prosecution to provide notice, regardless of how it intends to use the extrinsic act evidence at trial, i.e., during its case-in-chief, for impeachment, or for possible rebuttal. The court in its discretion may, under the facts, decide that the particular request or notice was not reasonable, either because of the lack of timeliness or completeness. Because the notice requirement serves as condition precedent to admissibility of 404(b) evidence, the offered evidence is inadmissible if the court decides that the notice requirement has not been met.

Nothing in the amendment precludes the court from requiring the government to provide it with an opportunity to rule in limine on 404(b) evidence before it is offered or even mentioned during trial. When ruling in limine, the court may require the government to disclose to it the specifics of such evidence which the court must consider in determining admissibility.

The amendment does not extend to evidence of acts which are "intrinsic" to the charged offense, see United States v. Williams, 900 F.2d 823 (5th Cir. 1990) (noting distinction between 404(b) evidence and intrinsic offense evidence). Nor is the amendment intended to redefine what evidence would otherwise be admissible under Rule 404(b). Finally, the Committee does not intend through the amendment to affect the role of the court and the jury in considering such evidence. See United States v. Huddleston, 485 U.S. 681, 108 S.Ct 1496 (1988).

Committee Notes on Rules—2000 Amendment

Rule 404(a)(1) has been amended to provide that when the accused attacks the character of an alleged victim under subdivision (a)(2) of this Rule, the door is opened to an attack on the same character trait of the accused. Current law does not allow the government to introduce negative character evidence as to the accused unless the accused introduces evidence of good character. See, e.g., United States v. Fountain, 768 F.2d 790 (7th Cir. 1985) (when the accused offers proof of self-defense, this permits proof of the alleged victim's character trait for peacefulness, but it does not permit proof of the accused's character trait for violence).

The amendment makes clear that the accused cannot attack the alleged victim's character and yet remain shielded from the disclosure of equally relevant evidence concerning the same character trait of the accused. For example, in a murder case with a claim of self-defense, the accused, to bolster this defense, might offer evidence of the alleged victim's violent disposition. If the government has evidence that the accused has a violent character, but is not allowed to offer this evidence as part of its rebuttal, the jury has only part of the information it needs for an informed assessment of the probabilities as to who was the initial aggressor. This may be the case even if evidence of the accused's prior violent acts is admitted under Rule 404(b), because such evidence can be admitted only for limited purposes and not to show action in conformity with the accused's character on a specific occasion. Thus, the amendment is designed to permit a more balanced presentation of character evidence when an accused chooses to attack the character of the alleged victim.

The amendment does not affect the admissibility of evidence of specific acts of uncharged misconduct offered for a purpose other than proving character under Rule 404(b). Nor does it affect the standards for proof of character by evidence of other sexual behavior or sexual offenses under Rules 412–415. By its placement in Rule 404(a)(1), the amendment covers only proof of character by way of reputation or opinion.

The amendment does not permit proof of the accused's character if the accused merely uses character evidence for a purpose other than to prove the alleged victim's propensity to act in a certain way. See United States v. Burks, 470 F.2d 432, 434–5 (D.C.Cir. 1972) (evidence of the alleged victim's violent character, when known by the accused, was admissible "on the issue of whether or not the defendant reasonably feared he was in danger of imminent great bodily harm"). Finally, the amendment does not permit proof of the accused's character when the accused attacks the alleged victim's character as a witness under Rule 608 or 609.

The term "alleged" is inserted before each reference to "victim" in the Rule, in order to provide consistency with Evidence Rule 412.

GAP Report—Proposed Amendment to Rule 404(a). The Committee made the following changes to the published draft of the proposed amendment to Evidence Rule 404(a):

1. The term "a pertinent trait of character" was changed to "the same trait of character," in order to limit the scope of the government's rebuttal. The Committee Note was revised to accord with this change in the text.

2. The word "alleged" was added before each reference in the Rule to a "victim" in order to provide consistency with Evidence Rule 412. The Committee Note was amended to accord with this change in the text.

3. The Committee Note was amended to clarify that rebuttal is not permitted under this Rule if the accused proffers evidence of the alleged victim's character for a purpose other than to prove the alleged victim's propensity to act in a certain manner.

Committee Notes on Rules—2006 Amendment

The Rule has been amended to clarify that in a civil case evidence of a person's character is never admissible to prove that the person acted in conformity with the character trait. The amendment resolves the dispute in the case law over whether the exceptions in subdivisions (a)(1) and (2) permit the circumstantial use of character evidence in civil cases. Compare Carson v. Polley, 689 F.2d 562, 576 (5th Cir. 1982) ("when a central issue in a case is close to one of a criminal nature, the exceptions to the Rule 404(a) ban on character evidence may be invoked"), with SEC v. Towers Financial Corp., 966 F.Supp. 203 (S.D.N.Y. 1997) (relying on the terms "accused" and "prosecution" in Rule 404(a) to conclude that the exceptions in subdivisions (a)(1) and (2) are inapplicable in civil cases). The amendment is consistent with the original intent of the Rule, which was to prohibit the circumstantial use of character evidence in civil cases, even where closely related to criminal charges. See Ginter v. Northwestern Mut. Life Ins. Co., 576 F.Supp. 627, 629–30 (D. Ky.1984) ("It seems beyond peradventure of doubt that the drafters of F.R.Evi. 404(a) explicitly intended that all character evidence, except where 'character is at issue' was to be excluded" in civil cases).

The circumstantial use of character evidence is generally discouraged because it carries serious risks of prejudice, confusion and delay. See Michelson v. United States, 335 U.S. 469, 476 (1948) ("The overriding policy of excluding such evidence, despite its admitted probative value, is the practical experience that its disallowance tends to prevent confusion of issues, unfair surprise and undue prejudice."). In criminal cases, the so-called "mercy rule" permits a criminal defendant to introduce evidence of pertinent character traits of the defendant and the victim. But that is because the accused, whose liberty is at stake, may need "a counterweight against the strong investigative and prosecutorial resources of the government." C. Mueller & L. Kirkpatrick, Evidence: Practice Under the Rules, pp. 264–5 (2d ed. 1999). See also Richard Uviller, Evidence of Character to Prove Conduct: Illusion, Illogic, and Injustice in the Courtroom, 130 U.Pa.L.Rev. 845, 855 (1982) (the rule prohibiting circumstantial use of character evidence "was relaxed to allow the criminal defendant with so much at stake and so little available in the way of conventional proof to have special dispensation to tell the factfinder just what sort of person he really is"). Those concerns do not apply to parties in civil cases.

The amendment also clarifies that evidence otherwise admissible under Rule 404(a)(2) may nonetheless be excluded in a criminal case involving sexual misconduct. In such a case, the admissibility of evidence of the victim's sexual behavior and predisposition is governed by the more stringent provisions of Rule 412.

Nothing in the amendment is intended to affect the scope of Rule 404(b). While Rule 404(b) refers to the "accused," the "prosecution," and a "criminal case," it does so only in the context of a notice requirement. The admissibility standards of Rule 404(b) remain fully applicable to both civil and criminal cases.

Changes Made After Publication and Comments. No changes were made to the text of the proposed amendment as released for public comment. A paragraph was added to the Committee Note to state that the amendment does not affect the use of Rule 404(b) in civil cases.

Committee Notes on Rules—2011 Amendment

The language of Rule 404 has been amended as part of the restyling of the Evidence Rules to make them more easily understood and to make style and terminology consistent throughout the rules. These changes are intended to be stylistic only. There is no intent to change any result in any ruling on evidence admissibility.

Committee Notes on Rules—2020 Amendment

Rule 404(b) has been amended principally to impose additional notice requirements on the prosecution in a criminal case. In addition, clarifications have been made to the text and headings.

The notice provision has been changed in a number of respects:

• The prosecution must not only identify the evidence that it intends to offer pursuant to the rule but also articulate a non-propensity purpose for which the evidence is offered and the basis for concluding that the evidence is relevant in light of this purpose. The earlier requirement that the prosecution provide notice of only the "general nature" of the evidence was understood by some courts to permit the government to satisfy the notice obligation without describing the specific act that the evidence would tend to prove, and without explaining the relevance of the evidence for a non-propensity purpose. This amendment makes clear what notice is required.

• The pretrial notice must be in writing—which requirement is satisfied by notice in electronic form. See Rule 101(b)(6). Requiring the notice to be in writing provides certainty and reduces arguments about whether notice was actually provided.

• Notice must be provided before trial in such time as to allow the defendant a fair opportunity to meet the evidence, unless the court excuses that requirement upon a showing of good cause. See Rules 609(b), 807, and 902(11). Advance notice of Rule 404(b) evidence is important so that the parties and the court have adequate opportunity to assess the evidence, the purpose for which it is offered, and whether the requirements of Rule 403 have been satisfied—even in cases in which a final determination as to the admissibility of the evidence must await trial. When notice is provided during trial after a finding of good cause, the court may need to consider protective measures to assure that the opponent is not prejudiced. See, e.g., United States v. Lopez-Gutierrez, 83 F.3d 1235 (10th Cir. 1996) (notice given at trial due to good cause; the trial court properly made the witness available to the defendant before the bad act evidence was introduced); United States v. Perez-Tosta, 36 F.3d 1552 (11th Cir. 1994) (defendant was granted five days to prepare after notice was given, upon good cause, just before voir dire).

• The good cause exception applies not only to the timing of the notice as a whole but also to the timing of the obligations to articulate a non-propensity purpose and the reasoning supporting that purpose. A good cause exception for the timing of the articulation requirements is necessary because in some cases an additional permissible purpose for the evidence may not become clear until just before, or even during, trial.

• Finally, the amendment eliminates the requirement that the defendant must make a request before notice is provided. That requirement is not found in any other notice provision in the Federal Rules of Evidence. It has resulted mostly in boilerplate demands on the one hand, and a trap for the unwary on the other. Moreover, many local rules require the government to provide notice of Rule 404(b) material without regard to whether it has been requested. And in many cases, notice is provided when the government moves in limine for an advance ruling on the admissibility of Rule 404(b) evidence. The request requirement has thus outlived any usefulness it may once have had.

As to the textual clarifications, the word "other" is restored to the location it held before restyling in 2011, to confirm that Rule 404(b) applies to crimes, wrongs and acts "other" than those at issue in the case; and the headings are changed accordingly. No substantive change is intended.
