Evidence Flashcards
Relevance
Relevance
To be admissible, evidence must be both logically and legally relevant. Relevant evidence is admissible unless another rule provides otherwise.
Logical Relevance
Evidence is logically relevant if it has any tendency to prove or disprove a material fact. (In CA, the material fact must be in dispute).
Legal Relevance
Evidence is legally relevant if it’s not excluded under FRE 403/CEC 352.
Relevance
FRE 403/CEC 352
Under FRE 403/CEC 352, the court may exclude evidence if its probative value is substantially outweighed by a danger of:
1. unfair prejudice,
2. confusing the issues,
3. misleading the jury,
4. undue delay,
5. wasting time, or
6. being needlessly cumulative.
Relevance

Physical & Documentary Evidence
Authentication of Evidence (General Rule)
All evidence must be authenticated before being admitted, i.e., a party must prove that the item is what the party purports it to be.
Physical & Documentary Evidence
Authentication of Evidence (Physical Evidence)
Physical evidence may be authenticated through (a) W testimony, or (b) a substantially unbroken chain of custody.
Physical & Documentary Evidence
Authentication of Evidence (Voice Recordings)
Voice recordings may be authenticated by anyone who has (1) heard the person speak, and (2) identified the recorded person as the speaker.
Physical & Documentary Evidence
Best Evidence Rule
- To prove the contents of the writing, a party must provide the original dodument (or reliable duplicate/photocopy).
- In CA, this rule is called the Secondary Evidence Rule.
- Under the FRE, handwritten duplicates are not admissible. In CA, handwritten duplicates are admissible.
Character Evidence
Character Evidence (General Rule)
- Generally, character evidence is not admissible to show propensity (that a person acted in conformity with a character trait on a particular occasion).
- However, character evidence is admissible:
(a) for non-propensity purpose, or
(b) when the character is “at issue” and an essetial element of the case.
Character rules can overlap with impeachment rules when a witness is on the stand. If the purpose for the character evidence is to prove that a W is untruthful -> impeachment rules, if it is for any other purpose -> character evidence rule.
Character Evidence
Character Evidence (Criminal Case)
- Defendant’s Character: In criminal cases, the prosecution is not allowed to present character evidence of the D to prove propensity, unless the D first “opens the door” and presents evidence of that character trait.
- Victim’s Character (Non Sex-Offense): Except in sex-offense cases, a D may offer evidence of the victim’s character to prove the D’s innocence.
- Victim’s Character (Sex Offense): For sex-offense cases, evidence to prove a victim’s sexual behaivior is generally not admissible.
- Victim’s Character (Homicide): Under the FRE, in a homicide case, a D may offer evidence of the victim’s character for violence to establish self-defense.
Character Evidence
Methods of Proving Character
When character evidence is admissible, it may be proven by:
(A) opinion or reputation in the community, in all instances; or
(B) specific acts, only (a) on cross-examination, or (b) if the character is “at issue.”
Prior Bad Acts
Prior Bad Acts
- Evidence of prior bad acts is not admissible to show propensity (that a person acted in conformity with a character trait on a particular occasion).
- However, it may be admissible for other purposes suc as proving motive, identity, mistake, intent, common scheme, or knowledge.
MIMICK
Impeachment
Prior Inconsistent Statements
- Prior inconsistent statements are admissible to impeach a W’s trial testimony.
- Extrinsic evidence is admissible only if either:
(a) (i) the W is first given an opportunity to explain the statement, and (ii) the adverse party is given an opportunity to examine the W about it; or
(b) justice so requires (e.g. W becomes unavailable).
Impeachment
Prior Convictions (FRE)
- Under the FRE, prior felony or misdemeanor convictions involving dishonesty are always admissible to impeach a W.
- All other misdemeanors are NOT admissible to impeach.
- Felonies that DO NOT involve dishonesty are admissible to impeach, subject to the court’s balancing.
Impeachment
Prior Convictions (CA)
- In CA, prior felony convictions involving moral turpitude are admissible to impeach. Felonies that DO NOT not involve moral turpitude are NOT admissible.
- Moral turpitude includes crimes involving lying, violence, sex crime, and extreme reckless.
- In a criminal case, misdemeanor convictions are admissible for crimes involving moral turpitude.
Impeachment
Specific Acts (“Bad Acts”)
- Under the FRE, W’s specific acts (prior bad acts) are admissible to impeach the W’s character for truthfulness by questioning him on cross-examination. No extrinsic evidence is allowed.
- In CA, prior bad acts are generally NOT admissible. However, they are admissible if the act(s) involve moral turpitude.
Witness Examination
Lay Witness
- A lay W may only testify to matters of which he has personal knowledge.
- A lay W may only offer an opinion if it is:
1. rationally based on the W’s perception, and
2. helpful to the factfinder.
Witness Examination
Expert Witness
Expert testimoby is permitted when:
1. the W is qualified as an expert,
2. the testimony is helpful to the factfinder,
3. the testimony is based on sufficient facts or data,
4. the testimony is based on reliable principles and methods, and
5. the expert has reasonably applied the principles and methods to the facts to the case.
Witness Examination/Presentation of Evidence
