In accordance with the bulk of judicial authority, the inquiry is strictly limited to character for truth and veracity rather than allowing evidence as to character generally. The result is to sharpen relevancy, to reduce surprise and confusion, and to make the lot of the witness somewhat less unattractive. See McCormick (2d ed.) § 44 and the Reporter's Comment accompanying Rule 404(a). "Attacking a witness' character is often but a feeble and ineffective contribution to the proof of the issue; and its drawbacks appear in their most emphasized form where the broader method of attack is allowed." 3 Wigmore § 923, at 728.
Character evidence in support of credibility is admissible only after the witness' character has first been attacked. See Rule 607(b). This is also in accord with the common law rule. McCormick (2d ed.) § 49, at 105; 4 Wigmore § 1104. Opinion or reputation testimony to the effect that the witness is untruthful specifically qualifies as an attack as would evidence of conviction of crime. Whether character evidence should be admitted to meet other forms of attack is, as the Reporter's Comment to Rule 607(b) suggests, best left to the discretion of the trial judge who has Rule 403 for guidance.
Rule 607(a) permits either party to impeach a witness. This rule, however, limits inquiry into specific acts when testing the knowledge of character witnesses to cross-examination. The rationale behind the limitation is to bar the direct examiner from the inquiry when "impeachment" of one's own witness becomes a disguise for using specific acts to prove character rather than the required reputation or opinion evidence. Because a party does have a choice as to character witnesses the need to impeach such witness by inquiring into specific acts should not arise. This rule follows Alaska R. Civ. P. 43(g) (11) [a], superseded by this rule.
The second sentence of this subdivision bars the use of evidence of specific incidents to impeach or support the credibility of a witness, unless otherwise provided in a rule of court or legislative enactment. See, e.g., Rule 609 (prior conviction), Rule 613 (inconsistent statement and bias). This follows Alaska R. Civ. P. 43(g) (11), superseded by this rule, and a trend in some jurisdictions to prohibit impeachment by "bad acts" other than criminal convictions. This is consistent with Rule 405 which forecloses use of evidence of specific incidents as proof of character unless character is an issue in the case. See also Uniform Rule 22(d); Kansas Rule 60-422, for similar provisions.
This subdivision departs from the Federal Rule which permits evidence of specific instances of conduct, if probative of the trait of truthfulness or untruthfulness, to support or attack a witness' credibility. The Federal Rule was adopted with little debate or attention although it expresses what was previously a minority view among the federal circuits. By eliminating this type of evidence, the need to protect witnesses against waiving their privilege against self-incrimination when examined with respect to matters relating to credibility is also eliminated.
