Federal Rules

(a) Reputation or Opinion Evidence. A witness’s credibility may be attacked or supported by testimony about the witness’s reputation for having a character for truthfulness or untruthfulness, or by testimony in the form of an opinion about that character. But evidence of truthful character is admissible only after the witness’s character for truthfulness has been attacked.

(b) Specific Instances of Conduct. Except for a criminal conviction under Rule 609, extrinsic evidence is not admissible to prove specific instances of a witness’s conduct in order to attack or support the witness’s character for truthfulness. But the court may, on cross-examination, allow them to be inquired into if they are probative of the character for truthfulness or untruthfulness of:

(1) the witness; or

(2) another witness whose character the witness being cross-examined has testified about.

By testifying on another matter, a witness does not waive any privilege against self-incrimination for testimony that relates only to the witness’s character for truthfulness.

Notes of Advisory Committee on Proposed Rules

Subdivision (a). In Rule 404(a) the general position is taken that character evidence is not admissible for the purpose of proving that the person acted in conformity therewith, subject, however, to several exceptions, one of which is character evidence of a witness as bearing upon his credibility. The present rule develops that exception.

In accordance with the bulk of judicial authority, the inquiry is strictly limited to character for veracity, rather than allowing evidence as to character generally. The result is to sharpen relevancy, to reduce surprise, waste of time, and confusion, and to make the lot of the witness somewhat less unattractive. McCormick §44.

The use of opinion and reputation evidence as means of proving the character of witnesses is consistent with Rule 405(a). While the modern practice has purported to exclude opinion witnesses who testify to reputation seem in fact often to be giving their opinions, disguised somewhat misleadingly as reputation. See McCormick §44. And even under the modern practice, a common relaxation has allowed inquiry as to whether the witnesses would believe the principal witness under oath. United States v. Walker, 313 F.2d 236 (6th Cir. 1963), and cases cited therein; McCormick §44, pp. 94–95, n. 3.

Character evidence in support of credibility is admissible under the rule only after the witness’ character has first been attacked, as has been the case at common law. Maguire, Weinstein, et al., Cases on Evidence 295 (5th ed. 1965); McCormick §49, p. 105; 4 Wigmore §1104. The enormous needless consumption of time which a contrary practice would entail justifies the limitation. Opinion or reputation that the witness is untruthful specifically qualifies as an attack under the rule, and evidence or misconduct, including conviction of crime, and of corruption also fall within this category. Evidence of bias or interest does not. McCormick §49; 4 Wigmore §§1106, 1107. Whether evidence in the form of contradiction is an attack upon the character of the witness must depend §§1108, 1109.

As to the use of specific instances on direct by an opinion witness, see the Advisory Committee's Note to Rule 405, supra.

Subdivision (b). In conformity with Rule 405, which forecloses use of evidence of specific incidents as proof in chief of character unless character is an issue in the case, the present rule generally bars evidence of specific instances of conduct of a witness for the purpose of attacking or supporting his credibility. There are, however, two exceptions: (1) specific instances are provable when they have been the subject of criminal conviction, and (2) specific instances may be inquired into on cross-examination of the principal witness or of a witness giving an opinion of his character for truthfulness.

(1) Conviction of crime as a technique of impeachment is treated in detail in Rule 609, and here is merely recognized as an exception to the general rule excluding evidence of specific incidents for impeachment purposes.

(2) Particular instances of conduct, though not the subject of criminal conviction, may be inquired into on cross-examination of the principal witness himself or of a witness who testifies concerning his character for truthfulness. Effective cross-examination demands that some allowance be made for going into matters of this kind, but the possibilities of abuse are substantial. Consequently safeguards are erected in the form of specific requirements that the instances inquired into be probative of truthfulness or its opposite and not remote in time. Also, the overriding protection of Rule 403 requires that probative value not be outweighed by danger of unfair prejudice, confusion of issues, or misleading the jury, and that of Rule 611 bars harassment and undue embarrassment.

The final sentence constitutes a rejection of the doctrine of such cases as People v. Sorge, 301 N.Y. 198, 93 N.E.2d 637 (1950), that any past criminal act relevant to credibility may be inquired into on cross-examination, in apparent disregard of the privilege against self-incrimination. While it is clear that an ordinary witness cannot make a partial disclosure of incriminating matter and then invoke the privilege on cross-examination, no tenable contention can be made that merely by testifying he waives his right to foreclose inquiry on cross-examination into criminal activities for the purpose of attacking his credibility. So to hold would reduce the privilege to a nullity. While it is true that an accused, unlike an ordinary witness, has an option whether to testify, if the option can be exercised only at the price of opening up inquiry as to any and all criminal acts committed during his lifetime, the right to testify could scarcely be said to possess much vitality. In Griffin v. California, 380 U.S. 609, 85 S.Ct. 1229, 14 L.Ed.2d 106 (1965), the Court held that allowing comment on the election of an accused not to testify exacted a constitutionally impermissible price, and so here. While no specific provision in terms confers constitutional status on the right of an accused to take the stand in his own defense, the existence of the right is so completely recognized that a denial of it or substantial infringement upon it would surely be of due process dimensions. See Ferguson v. Georgia, 365 U.S. 570, 81 S.Ct. 756, 5 L.Ed.2d 783 (1961); McCormick §131; 8 Wigmore §2276 (McNaughton Rev. 1961). In any event, wholly aside from constitutional considerations, the provision represents a sound policy.

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

Rule 608(a) as submitted by the Court permitted attack to be made upon the character for truthfulness or untruthfulness of a witness either by reputation or opinion testimony. For the same reasons underlying its decision to eliminate the admissibility of opinion testimony in Rule 405(a), the Committee amended Rule 608(a) to delete the reference to opinion testimony.

The second sentence of Rule 608(b) as submitted by the Court permitted specific instances of misconduct of a witness to be inquired into on cross-examination for the purpose of attacking his credibility, if probative of truthfulness or untruthfulness, “and not remote in time”. Such cross-examination could be of the witness himself or of another witness who testifies as to “his” character for truthfulness or untruthfulness.

The Committee amended the Rule to emphasize the discretionary power of the court in permitting such testimony and deleted the reference to remoteness in time as being unnecessary and confusing (remoteness from time of trial or remoteness from the incident involved?). As recast, the Committee amendment also makes clear the antecedent of “his” in the original Court proposal.

Notes of Conference Committee, House Report No. 93–1597

The Senate amendment adds the words “opinion or” to conform the first sentence of the rule with the remainder of the rule.

The Conference adopts the Senate amendment.

Notes of Advisory Committee on Rules—1987 Amendment

The amendments are technical. No substantive change is intended.

Notes of Advisory Committee on Rules—1988 Amendment

The amendment is technical. No substantive change is intended.

Committee Notes on Rules—2003 Amendment

The Rule has been amended to clarify that the absolute prohibition on extrinsic evidence applies only when the sole reason for proffering that evidence is to attack or support the witness’ character for truthfulness. See United States v. Abel, 469 U.S. 45 (1984); United States v. Fusco, 748 F.2d 996 (5th Cir. 1984) (Rule 608(b) limits the use of evidence “designed to show that the witness has done things, unrelated to the suit being tried, that make him more or less believable per se”); Ohio R.Evid. 608(b). On occasion the Rule's use of the overbroad term “credibility” has been read “to bar extrinsic evidence for bias, competency and contradiction impeachment since they too deal with credibility.” American Bar Association Section of Litigation, Emerging Problems Under the Federal Rules of Evidence at 161 (3d ed. 1998). The amendment conforms the language of the Rule to its original intent, which was to impose an absolute bar on extrinsic evidence only if the sole purpose for offering the evidence was to prove the witness’ character for veracity. See Advisory Committee Note to Rule 608(b) (stating that the Rule is “[i]n conformity with Rule 405, which forecloses use of evidence of specific incidents as proof in chief of character unless character is in issue in the case . . .”).

By limiting the application of the Rule to proof of a witness’ character for truthfulness, the amendment leaves the admissibility of extrinsic evidence offered for other grounds of impeachment (such as contradiction, prior inconsistent statement, bias and mental capacity) to Rules 402 and 403. See, e.g., United States v. Winchenbach, 197 F.3d 548 (1st Cir. 1999) (admissibility of a prior inconsistent statement offered for impeachment is governed by Rules 402 and 403, not Rule 608(b)); United States v. Tarantino, 846 F.2d 1384 (D.C. Cir. 1988) (admissibility of extrinsic evidence offered to contradict a witness is governed by Rules 402 and 403); United States v. Lindemann, 85 F.3d 1232 (7th Cir. 1996) (admissibility of extrinsic evidence of bias is governed by Rules 402 and 403).

It should be noted that the extrinsic evidence prohibition of Rule 608(b) bars any reference to the consequences that a witness might have suffered as a result of an alleged bad act. For example, Rule 608(b) prohibits counsel from mentioning that a witness was suspended or disciplined for the conduct that is the subject of impeachment, when that conduct is offered only to prove the character of the witness. See United States v. Davis, 183 F.3d 231, 257 n.12 (3d Cir. 1999) (emphasizing that in attacking the defendant's character for truthfulness “the government cannot make reference to Davis's forty-four day suspension or that Internal Affairs found that he lied about” an incident because “[s]uch evidence would not only be hearsay to the extent it contains assertion of fact, it would be inadmissible extrinsic evidence under Rule 608(b)”). See also Stephen A. Saltzburg, Impeaching the Witness: Prior Bad Acts and Extrinsic Evidence, 7 Crim. Just. 28, 31 (Winter 1993) (“counsel should not be permitted to circumvent the no-extrinsic-evidence provision by tucking a third person's opinion about prior acts into a question asked of the witness who has denied the act.”).

For purposes of consistency the term “credibility” has been replaced by the term “character for truthfulness” in the last sentence of subdivision (b). The term “credibility” is also used in subdivision (a). But the Committee found it unnecessary to substitute “character for truthfulness” for “credibility” in Rule 608(a), because subdivision (a)(1) already serves to limit impeachment to proof of such character.

Rules 609(a) and 610 also use the term “credibility” when the intent of those Rules is to regulate impeachment of a witness’ character for truthfulness. No inference should be derived from the fact that the Committee proposed an amendment to Rule 608(b) but not to Rules 609 and 610.

Changes Made After Publication and Comments. The last sentence of Rule 608(b) was changed to substitute the term “character for truthfulness” for the existing term “credibility.” This change was made in accordance with public comment suggesting that it would be helpful to provide uniform terminology throughout Rule 608(b). A stylistic change was also made to the last sentence of Rule 608(b).

Committee Notes on Rules—2011 Amendment

The language of Rule 608 has been amended as part of the general 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.

The Committee is aware that the Rule’s limitation of bad-act impeachment to “cross-examination” is trumped by Rule 607, which allows a party to impeach witnesses on direct examination. Courts have not relied on the term “on cross-examination” to limit impeachment that would otherwise be permissible under Rules 607 and 608. The Committee therefore concluded that no change to the language of the Rule was necessary in the context of a restyling project.
