Evidence Flashcards
Logical relevance rule
Evidence is logically relevant if it tends to be material to a disputed fact.
Legal relevance (balancing test)
Relevant evidence may be excluded if its probative value is substantially outweighed by the danger of unfair prejudice, confusion of issues, misleading the jury, or wasting time. (FRE 403; CEC 352)
CA Prop 8 (always list at top under Preliminary matters heading if prompted for CEC)
- If case is criminal: i. Under Proposition 8 of the California Constitution (hereafter Prop. 8), any evidence that is relevant may be admitted in a criminal case. However, Prop. 8 makes an exception for balancing under California Evidence Code (hereafter CEC) 352, which gives a court discretion in excluding relevant evidence if its probative value is substantially outweighed by a risk of unfair prejudice, confusion of issues, or misleading the jury.
- If case is civil: This case is civil so Prop. 8 will not be applied to the evidence.
Public policy exclusions
- Subsequent remedial measures
- Liability insurance
- Offers to pay medical expenses
- Settlement offers
- Offer to plead guilty
- Expressions of sympathy (CEC)
**None of these are admissible to prove culpable conduct
*Purpose for all of these is to encourage behaviors for greater good of society
Personal knowledge of witness rule (competency)
Witness must have personal knowledge of the matter about which he is to testify and must declare that he will testify truthfully.
Objections to form of questioning
- Narrative (what happened?)
- Unresponsive (witness answer is unresponsive or constitutes an answer to a question other than the one that was asked, or goes beyond the scope of the original question, it is considered nonresponsive and should not be admitted into evidence.)
- Compound (two q’s in one)
- Argumentative (q is combative)
- Leading (q phrased to suggest answer, isn’t it true?)
- Assumes facts not in evidence (when did you make your will? when no evidence witness made a will)
Present recollection refreshed rule
Allows any item to be used to refresh a witness’ memory. Once shown the item, the witness must then testify entirely from his refreshed memory (witness cannot read from the refreshing document).
Opinion testimony: Lay opinion
A lay opinion is admissible if it is based on the perception of the witness, it is helpful to the trier of fact, and NOT based on specialized or technical knowledge (witness must be qualified as expert before giving opinion of that nature).
**(e.g., estimating driving speed, value of property, identity of person, physical condition, familiarity of handwriting, etc.)
Opinion testimony: expert testimony
*Shorthand rule: Admissible if relevant and reliable.
Admissible if all are met:
(1) specialized knowledge will help trier of fact in understanding evidence
(2) witness is qualified as an expert by knowledge, skill, experience, training or education
(3) testimony based on sufficient facts or data
(4) testimony is product of reliable principles and methods.
**Daubert and Kelly not applied if expert testimony is NOT scientific.
FRE: Daubert std of reliability requires substance of expert’s testimony be
- Peer reviewed, published in sci journals, tested, known for low error rate, subject to reasonable level of acceptance
CEC: Kelly/Frye std of reliability requires
- Proponent must prove sci theory/technique has been generally accepted as valid and reliable in relevant sci field
(5) witness applied principles reliably to facts of case.

3 forms of character evidence to prove someone’s character
- Reputation
- Opinion
- Specific acts
CE in Civil court: character evidence rule
Character evidence is generally inadmissible to prove conduct in conformity with that character trait on a particular occasion.
CE in Civil court: character at issue exception
Character evidence IS admissible where character is “at issue” and is an essential element of the case. (e.g., defamation bc person’s character matters when assessing reputational damage)
CE in Civil court: FRE exception sexual assault or child molestation
Character evidence can be admitted in cases based on SA, DV, or child molestation (CEC does NOT have this exception).
CE in Civil court: rape shield provisions (generally disallow evidence of V’s past sex conduct)
- FRE: P must put her reputation in issue for reputation evidence to be admitted. Reputation, opinion and specific acts may be admitted if the probative value substantially outweighs the danger of unfair prejudice (higher standard than typical balancing test).
- CEC: D cannot offer evidence of P’s prior sexual conduct unless to prove prior sexual conduct with D.
CE crim. court rule
Where character evidence is admissible, the character trait must always be pertinent to the case, but rules of admission differ depending on whose character it is.
CE crim. court, D’s character general rule
Only D can “open the door” to evidence of a pertinent character trait (reputation or opinion evidence), but once opened, the prosecution may:
- Call a witness to rebut D’s claim of good character (R or O)
- Cross exam the D’s character witness (R, O OR SA)
*Prosecution can ask about specific bad acts but cannot introduce extrinsic evidence to prove it
CE crim. court, D’s character general rule exceptions
- FRE only: If D offers evidence of V’s character, prosecution can offer evidence that D has the same character trait (e.g., violent).
- CEC only: When D offers evidence of V’s violent character, V can offer evidence of D’s violent character.
- CEC only: evidence of D’s prior commission of elder abuse, SA or DV (including child molestation) is admissible in a criminal case in which D is accused of committing similar act.
CE crim. court, V’s character general rule for FRE and CA
*FRE: Only D can “open the door” to evidence of V’s pertinent character trait (reputation or opinion evidence), but once opened, the prosecution may:
- Introduce rebuttal evidence of V’s character (R or O) OR
- Attack D’s character for same trait
*CA: crim. D may introduce evidence of V’s character when it is relevant to the defense asserted. Unlike in federal court, evidence of specific acts, in addition to opinion and reputation evidence, may be used in California for this purpose.
CE crim court V’s character FRE only exception: V first aggressor
If D claims or offers evidence that V was first aggressor, then prosecution can offer reputation or opinion evidence only for V’s peacefulness.
CE crim court V’s character, Rape and SA case special rules
Rape shield provisions generally disallow evidence of a rape or SA victim’s past sexual conduct.
- R & O evidence always inadmissible.
- Specific acts admissible only to prove limited issue of prior acts of consensual sex with D or con. required
*CEC only: D can offer V’s prior sexual conduct to show he reasonably believed she consented, but not to show that she did consent.
Criminal court evidence, specific bad act general rule
Except for the limited cross exam discussed above, the prosecution cannot introduce evidence of specific acts to prove character. However, evidence of prior bad acts may be admissible for another purpose (see below).
Other purpose for character evidence allowed in crim and civil cases
(MIMIC)
- Motive to commit crime
- Intent to commit act
- Mistake (evidence that D committed similar misconduct in past negates possibility of mistake)
- Identity of perpetrator (specific pattern of behavior)
- Common plan or scheme
