IMPEACHMENT Flashcards
GENERAL CONCEPTS
- Impeachment refers to discrediting a witness.
- When evidence is admissible only to impeach, it is not being offered as substantive evidence (to prove some fact at issue in the case) but to show that witness can’t be trusted.
Accrediting or Bolstering Generally Prohibited
- Generally, party is not permitted to bolster/accredit testimony of their witness (ex. by introducing a prior statement by witness that is consistent w/ their testimony) until witness has been impeached.
Exceptions to Rule Against Bolstering
- In certain cases, party may offer evidence that witness
made a timely complaint/a prior statement of ID (usually,
identifying D as perpetrator of charged crime) even if this tends to bolster their in-court testimony. - Prior ID may also serve as substantive evidence that ID was correct (see the Hearsay module).
Any Party May Impeach
- Witness may be impeached by any party, including party who called them.
Tip
- When a question involves party impeaching their own witness, be sure to avoid the following wrong answer choices reflecting CL, which prohibited impeaching your own witness unless the witness:
(1) Is an adverse party/identified w/ adverse party;
(2) Is hostile & affirmatively uncooperative;
(3) Is one whom party is required by law to call; or
(4) Gives surprise testimony that is affirmatively harmful to party calling them.
IMPEACHMENT METHODS
- Witness may be impeached either by
(1) cross (eliciting facts from witness that discredit their own testimony) or
(2) extrinsic evidence (calling other witnesses/ introducing docs that prove impeaching facts). - Certain grounds for impeachment require foundation be laid during cross b/f extrinsic evidence can be introduced.
- Other grounds allow impeachment to be accomplished only by cross & not by extrinsic evidence. (Note: The term “cross-examination” is used for convenience b/c it is usually an adverse witness who is impeached. But remember that a party may impeach their own witness, which would be on direct/redirect examination.)
- In the discussion that follows:
- Impeachment methods 1-4 (prior inconsistent statements; bias; sensory deficiencies; contradiction) involve impeaching a witness w/ facts that are specific to the current case; and
- Impeachment methods 5-7 (opinion/reputation evidence of untruthfulness; prior convictions; bad acts) involve impeaching witness w/ their general bad character for truthfulness
Prior Inconsistent Statements
MED
- Party may show, by cross/extrinsic evidence, that witness has, on another occasion, made statements inconsistent w/ their current testimony.
- To prove statement by extrinsic evidence, a proper foundation must be laid & statement must be relevant to some issue in the case.
Tip
- Most inconsistent statements are clearly contradictory
(ex. witness testifies that light was red, but previously told someone that light was green). - A prior statement that omits a fact asserted during the current testimony may constitute an inconsistency
if it would have been natural for witness to include fact in statement if they believed it to be true. On its own, witness’s present lack of memory of a fact is generally not inconsistent w/ a prior statement relating that fact (however, ct may find an inconsistency where witness’s memory loss appears to be feigned). On the other hand, if witness remembers fact on the stand, but didn’t remember fact in prior statement, the earlier
lack of memory is generally considered inconsistent.
When Admissible as Substantive Evidence
- Usually, prior inconsistent statements are hearsay,
admissible only for impeachment purposes. - If, however, testifying witness’s prior inconsistent statement was made under oath at a prior proceeding, it is admissible nonhearsay & may be admitted as substantive evidence of the facts stated (see the Hearsay module).
- The rationale is that statement is reliable b/c of oath, & b/c witness is now subject to cross about statement.
Foundation for Extrinsic Evidence
- Extrinsic evidence can be introduced to prove a prior inconsistent statement only if, at some point:
(1) Witness is given opportunity to explain/deny statement; and
(2) Adverse party is given opportunity to examine witness about statement; and
(3) is relevant to material issue (one other than witness’s credibility)
Tip
- Opportunity to explain/deny can be given before/after intro of extrinsic evidence.
Exceptions to Foundation Requirement
- Foundation requirement above (giving witness opportunity to explain/deny; allowing adverse party to examine them) does not apply:
- If prior inconsistent statement is OP’s statement
- An inconsistent statement by a hearsay declarant can be used to impeach hearsay declarant despite lack of a foundation.
- Ct may dispense w/ foundation requirement where justice requires (ex. when witness has left stand & is unavailable when their inconsistent statement is discovered).
Bias or Interest
MED
Evidence that a witness is biased/has an interest in outcome of case tends to show that witness has motive to lie.
Foundation for Extrinsic Evidence
- Much is left to ct’s discretion.
- Majority rule: B/f witness can be impeached by extrinsic evidence of bias/interest, they must first be asked about facts that show bias/interest on cross.
- Ct has discretion to permit extrinsic evidence even if witness admits bias.
Tip
Watch for facts indicating that foundation requirement for extrinsic evidence of bias/interest has been fulfilled. Evidence that is otherwise inadmissible (like arrests/liability insurance) may be introduced if relevant to bias, provided proper foundation is laid.
