Relevance
- To be admissible, evidence must be both logically and legally relevant. Relevant evidence is admissible unless another rule provides otherwise.
- 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).
- Evidence is legally relevant if its probative value is not substantially outweighed by a danger of unfair prejudice, confusing the issues, or wasting time.

California Proposition 8
Under California Proposition 8 (Prop 8), all relevant evidence is admissible in a criminal trial, subject to a few special exemptions.
“Here, this is a criminal case, so despite any objections discussed below, evidence still may be admissible under Prop 8. / But this is a civil case, so Prop 8 does not apply.”
Policy Exclusion
Subsequent Remedial Measures
- Because of public policy, evidence of subsequent remedial measures is not admissible to show culpability or negligence.

Physical & Documentary Evidence
Authentication of Evidence (General Rule)
All evidence, other than testimony, 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

Best Evidence Rule
- To prove the contents of the writing, a party must provide the original document (or reliable duplicate/photocopy).
- Under the FRE, handwritten duplicates are not admissible. In CA, handwritten duplicates are admissible.
- In CA, this rule is called the Secondary Evidence Rule. The SER is an exception to Prop 8.
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 purposes, or
(b) when the character is “at issue” (e.g. defamation, child custody cases).
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)
- In criminal cases, a D may introduce evidence of their own good character or the V’s bad character. Only if a D “opens the door” and presents evidence of the D’s or the V’s character, the prosecution may offer evidence of the D’s character for that character trait.
- Only if a D “opens the door” and presents evidence of the V’s (bad) character, the prosecution may offer evidence of the V’s good character.
- Limits on prosecution from offering CE is an exception to Prop 8.
Character Evidence
Methods of Proving Character (Criminal Cases)
- Where character evidence is allowable, only reputation and opinion evidence are allowed on both direct and cross.
- Specific acts may be asked about on cross, but no extrinsic evidence is permitted.
- In CA, all forms of evidence are admissible on both direct and cross to prove the V’s character.
Character Evidence
Prior Bad Acts
- Evidence of prior bad acts or crimes is not admissible to show propensity.
- However, it may be admissible for some other purpose, such as to show: intent, preparation, identity, knowledge, absence of mistake or accident, motive, opportunity, or plan.

- Prior inconsistent statements are admissible to impeach a W’s credibility.
- Extrinsic evidence is admissible only if:
(1) the W is given an opportunity to explain or deny, and
(2) the adverse party is given an opportunity to examine the W about it.
The limitation on extrinsic evidence is not applicable to statements by a party opponent.

Prior Convictions (FRE)
Under the FRE,
* Prior felony or misdemeanor convictions involving dishonesty are always admissible to impeach a W, and the judge has no discretion to exclude it unless it is more than 10 years old.

Specific Acts (“Bad Acts”)
- Under the FRE, W’s specific acts (prior bad acts) that are probative of truthfulness are admissible on cross by questioning him, but extrinsic evidence is never admissible.
- In CA, prior bad acts are only admissible in criminal cases under Prop 8 if the acts involve moral turpitude (extrinsic evidence is permitted).
