General Concept of Impeachment
• The proponent of a witness OR the opposing party may try to show flaws in the witness and his/her testimony
• The credibility of a witness may be attached by any party, including the party calling the
witness
5 types of impeachment
(1) Bias
• Relationship, etc.
(2) Impaired capacity
• Maybe drunk, etc.
(3) Bad character
• Prior bad acts
• Convictions
• Reputation or opinion
(4) Prior inconsistent statements
(5) Contradiction
Methods of impeachment
o Bias
o Impaired capacity
o Character evidence
o Prior inconsistent statements
o Contradiction
• Extrinsic only
Impeachment – Bias
Generally trying to show the witness is swayed in his testimony for some reason
United States v. Abel
o Abel indicted for robbery w/ 2 accomplices.
o Person on witness stand – bias?
- Want to cross-examine to show bias
• Aryan Brotherhood – prison gang
• Lie for each other on the witness stand - try to bring out part of organization sworn to lie on witness stand and are
biased against all
o Extreme: Most of the time have to do with relationship with one another, or interest in the lawsuit or the property
Impeachment – Sensory or Mental Capacity
Impeachment – Bad Character
See handout on character for truth and veracity.
(Witness on witness stand and trying to impeach with untruth – trying to show that they are a liar)
• A second witness testifies to the opinion or reputation of the first witness for untruthfulness
• Prosecutor could then call 1- character witnesses who say X is truthful, but practically speaking don’t want to
Impeachment – bad character contd.
o Cross specific instances of conduct
o Extrinsic evidence forbidden
- Must accept witnesses answer – cannot contradict by calling another witness – no trials within trials
o Examiner must have good faith basis for asking such questions about prior bad acts
- Cannot just make up a story
o Admitted at discretion of judge
Video Clip #1
o Defendant on witness stand – trying to impeach him
o Discharged from the army for psychiatric reasons
- Might come in to show whatever his perception of what happened may be altered by a mental capacity
o Beat up an officer with a shovel
- Prior act of violence – cannot bring in even under character evidence
o Arrested for assaulting an aid
- Prior act of violence – don’t come in
o Punch attorney in face
- Prior act of violence – don’t come in
o Isn’t it true you lied to a congressional aide?
- Not okay – cannot cross examine witness himself about own prior bad acts. Only reputation or opinion of the witness by someone else.
Video Clip #2
o Going to bias
- Maybe get a better deal for testifying?
o For acts of dishonesty
Prior Convictions - General Theory
Someone convicted of a crime would have no issue lying on a witness stand, despite being under oath. Oath means less to them.
Prior Convictions - General Rule
Prior Convictions - Break Down
• Civilian witness on stand – court must balance whether the conviction’s probative value for impeachment purposes is “substantially outweighed” by the danger of unfair prejudice
• Defendant on witness stand – court must balance whether the conviction’s probative value for impeachment purposes is “outweighed” by the danger of unfair prejudice
Crime involving dishonesty means:
Time limit for convictions
Time limit: 10 year rule. If prior conviction is older than 10 years, generally not going to come in.
Step by Step Approach to Priors (SEE HANDOUT)
Step 1: Is conviction or date of release from confinement from that conviction within 10 years?
• Judge can make exception
• If yes, go to step 2. If no, you’re done.
Step 2: Is the conviction
o Ex. said let me borrow that – knew you weren’t borrowing it, but stealing it – elevate to crime of dishonesty
o Rap sheet will not have enough info to figure this out – could say petty theft even though it was a theft with false statements – used false statements in course of the theft
Step 3: Is the conviction for a crime where the prosecution must prove false statement or dishonesty as an element?
Step 4: Is the witness also the accused in a criminal case? (is it a witness or the defendant?)
• If No – go to step 5
• If Yes – go to step 6
Step 5: Is the conviction’s probative value “substantially outweighed” by the danger of unfair prejudice?
• Judge has to decide is it substantially outweighed?
• If yes – conviction not admissible
• If no – conviction is admissible
• Ex. defendant on trial for robbery, witness takes stand and has prior robbery in her history – not going to be as concerned that jury will hear of witness’ robbery and
somehow equate that to convict defendant?
• Ex. involuntary manslaughter – could be an accident – do you allow impeach?
• **If D on witness stand – do not answer with substantially answer – that is for a witness.
Step 6: Is the conviction’s probative value outweighed (not substantially outweighed) by its prejudicial effect? (for defendant)
Robbery is a crime of violence, not necessarily a crime of dishonesty
Impeachment – Prior Inconsistent Statement - General Theory
Witness cannot keep story straight, says one thing on witness stand but said another thing prior to testifying. Witness cannot be believed because stories are inconsistent.
Impeachment – Prior Inconsistent Statement - Procedure
Extrinsic Evidence of a Prior Inconsistent Statement. Extrinsic evidence of a witness’s prior inconsistent statement is admissible only if the witness is given an opportunity to explain or deny the statement and an adverse party is given an opportunity to examine the witness about it, or if justice so requires. This subdivision (b) does not apply to an opposing party’s statement under Rule 801(d)(2).
Impeachment – Prior Inconsistent Statement - Example
o If witness A is on the witness stand, you attack the witness A directly with the prior inconsistent statement.
• Confront witness: isn’t it true you told the officer/whoever that the red car ran the green light
o If witness A admits making the statement, you are done. Got inconsistent statement in. Can use in argument.
o If the witness A denies making the statement you may call Witness B, the one who received the contradicting statement originally. Witness B will testify as to the contradicting statement.
• If you choose NOT to attack witness A while on the witness stand, you must NOT excuse witness A from the proceedings
o Can ask witness B: isn’t it true that witness A said this to you. Okay as long as witness A can come back/be recalled to explain inconsistency. Must have opportunity to explain the inconsistent statement.
o The opposing party may recall witness A to the stand to explain the inconsistencies
Harris v. New York
Cops interviewed defendant in course of investigating crime and violated Miranda rights. For case in chief, cannot bring in b/c in violation of Miranda. Defendant gets on witness stand and lies – makes statements completely contradictory to what told the cops. Prosecution confronts – isn’t it true you told the cops A, B, C. Defendant objected. Court rule: can use them for impeachment, to argue that defendant is a liar on the witness stand, but not to say prior statements were in fact true. Won’t let defendant benefit from procedural windfall. Need to give jury a limiting instruction – can only use to determine whether defendant’s testimony truthful or not, not for underlying elements.
Jenkins v. Anderson
Miranda rights only apply if you are subject to custodial interrogation. If they don’t give you Miranda rights or you aren’t subject to custodial interrogation and you don’t say anything in situation where you should have, that could be a problem. Using defendant’s pre-Miranda silence to impeach him on witness stand.
United States v. Havens
Search and seizure. Something obtained through illegal search and seizure. Cannot lie about whether in possession of something on the witness stand – it will come in to impeach you.
Contradiction
You have opposing evidence. Witness A on witness stand says the blue car ran the green light. Witness B says red car ran the green light. Can use to impeach the first witness. If separate witness, can argue truth of matter as well. People see it differently.
Impeachment – Rehabilitation
• General theory: Try to repair credibility after witness has been attacked
• General rule: Must have attack on character of witness before you can rehabilitate the
situation
Types of rehabilitation
(1) Let witness explain
(2) Evidence of good character of truthfulness – opinion or reputation
(3) Prior consistent statements (only if credibility is attacked – look into the rules for that)
