The giving of testimony, whether by an accused or by any other witness, does not operate as a waiver of the witness's privilege against self-incrimination when examined with respect to matters which relate only to character for truthfulness.
Tenn. R. Evid. 608
Advisory Commission Comments.
Part (a) admits opinion as well as community reputation to prove character. Presently Tennessee restricts proof to reputation evidence. Ford v. Ford, 26 Tenn. 91, 100-01 (1846). The proposed change is minimal, however, because Tennessee has allowed a character witness on the credibility issue to opine that the fact witness should or should not be believed. Ford v. Ford, 26 Tenn. 92, 102 (1846).
Part (b) reflects the Supreme Court's view of impeachment by prior bad acts. State v. Morgan, 541 S.W.2d 385 (Tenn. 1976), incorporated F.R.Evid. 608(b) into Tennessee case law. The proposed rule is even more specific than the federal version. It requires a jury-out hearing on probative value and basis for cross-examination, relatively recent misconduct, and notice plus analytical weighing of probative value versus unfair prejudice.
To the extent that State v. Caruthers, 676 S.W.2d 936 (Tenn. 1984), can be construed as allowing cross-examination about a prior act of rape to impeach, the proposal would change that result.
If the witness makes a sweeping claim of good conduct on direct examination, that claim may open the door to cross-examination without pretrial notice and with a lower standard of probativeness, as rebuttal of the broad claim would itself tend to show untruthfulness. Also, there may be instances where the prosecution would not discover the accused's bad acts until after the trial begins, making pretrial notice impossible; in such cases immediate notice and a hearing on the issue before the accused testifies should satisfy the spirit of the rule.
Note that the accused's failure to take the stand in face of an adverse ruling on admissibility of a prior bad act does not waive the right to assign error on appeal.
Part (c) conforms juvenile bad acts admissibility to the principles used with juvenile adjudications. See Rule 609(d).
Advisory Commission Comments [1991].
This is a technical amendment.
Advisory Commission Comments [2005].
Substituting "character for truthfulness" in place of "credibility" at the beginning and end of Rule 608(b) clarifies that contradiction impeachment by extrinsic evidence is permissible.
