Q

Character Evidence: Impeachment Purposes

A

Character evidence is admissible for impeachment purposes relevant to the witness’s character for truthfulness, in the form of reputation or opinion testimony.

In CA, credibility may be attacked by reputation or opinion evidence only as to the witness’s character for honesty or veracity.

The credibility of a witness may not be bolstered, evidence of truthful character is only admissible after witness’s character for truthfulness has been attacked. Impeachment without attacking truthfulness does not constitute an attack.

In CA, a criminal defendant can bolster his testimony for honesty and veracity
without any attempt at impeachment by the prosecution.

On cross-examination, a witness may be asked about specific instances of conduct if it is probative of the truthfulness of the witness or another witness about whose character the witness being cross-examined has testified.
