Impeachment Flashcards
what is impeachment?
when evidence is admitted for the purpose of showing that a witness can’t be trusted (to discredit them)
what is bolstering?
accrediting a witness’s testimony before it has been impeached
**NOTE = GENERALLY PROHIBITED
what are the two exceptions to the prohibition against bolstering?
party may offer “bolstering” evidence of…
1) a witness’s timely complaint (ie – sexual assault cases), or
2) a prior statement of identification (ie– identifying defendant as perpetrator of a charged crime)
true or false: a prior identification may serve as substantive evidence that the identification was correct.
TRUE
who may a witness be impeached by?
ANY PARTY (even the party who called them)
generally, via what two processes may a witness be impeached?
either by…
1) cross exam (or direct if its a party’s own witness), or
2) extrinsic evidence (calling other witnesses/producing docs to support impeaching facts)
which methods of impeachment involve impeaching a witness with facts that are SPECIFIC to the current case? (4)
impeachment by…
1) prior inconsistent statement
2) showing bias
3) showing sensory deficiencies
4) contradiction
what methods of impeachment involve impeaching a witness with their GENERAL character for UNTRUTHFULNESS? (3)
impeachment by…
1) opinion or reputation evidence for untruthfulness
2) prior convictions
3) prior bad acts
what is impeachment by prior inconsistent statement?
a party, by cross exam or extrinsic evidence, shows that the witness has, on another occasion, made statements inconsistent with their present testimony
what is required to prove a prior inconsistent statement by extrinsic evidence?
1) a proper foundation must be laid, and
2) the statement must be relevant to some issue in the case
under what circumstances may a prior statement that OMITS a fact asserted during the testimony be considered an INCONSISTENT statement?
when if would have been NATURAL for the witness to INCLUDE the fact in the statement if they believed it to be true
true or false: on its own, a witness’s present lack of memory of a fact is generally enough to be treated as an inconsistency with a prior statement relating that fact.
FALSE (generally NOT treated as an inconsistency absent any more facts)
when may a court find there’s been an inconsistency even where the witness has a present lack of memory of a fact?
when it appears that the witness’s memory loss is being faked
if a witness remembers a fact on the stand but DIDN’T remember the fact in an earlier statement, what will the court treat the prior lack of memory as?
a prior inconsistent statement
what is the one exception where a prior inconsistent statement is admissible for its TRUTH? (not simply impeachment)
when that prior inconsistent statement was made UNDER OATH
what is required for laying a proper foundation for extrinsic evidence to prove a prior inconsistent statement? (2 rqmts)
if at some point…
1) the witness is given an opportunity to explain or deny the statement (either before or after introduction of evidence), AND
2) the adverse party is given an opportunity to examine the witness about the statement (to explain, etc)
when does the foundation requirement for extrinsic evidence of prior inconsistent statements NOT apply? (3 situations)
when the prior inconsistent statement is…
1) made by an OPPOSING party,
2) made by a hearsay declarant and is being used to impeach that hearsay declarant, and
3) when justice so requires (ie– witness has left stand and is unavailable)
what is impeachment by showing bias/interest?
admitting evidence that a witness is biased or has an interest in the outcome of case to show they have a motive to lie
what is required to happen before a witness can be impeached by extrinsic evidence of bias?
they must first be asked about the facts that show bias or interest on cross examination (lays foundation)
true or false: a court still has discretion to permit extrinsic evidence even if the witness admits the bias.
TRUE
