Rule 608 A Witness’s Character for Truthfulness or Untruthfulness
Article VI. Witnesses
Rule Text
(a) Reputation 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. 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. The court may, on cross-examination, allow a party to inquire into specific instances of a witness’s conduct if they are probative of the character for truthfulness or untruthfulness of:
(1) The witness; or
(2) Another witness about whose character the witness being cross-examined has testified.
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.
