EVIDENCE RULE STATEMENTS Flashcards
California - Proposition 8
In California, Proposition 8, applicable exclusively to criminal proceedings, states that relevant evidence shall not be excluded unless, pursuant to CEC 352, the probative value of the evidence is substantially outweighed by the danger of unfair prejudice, confusing the issues, or misleading the jury.
Logical Relevance
Evidence is relevant if it tends to make any fact of consequence more or less probable that it would be without the evidence.
In California, it must also be relevant as to a disputed fact.
Legal Relevance
Courts may exclude relevant evidence if its probative value is substantially outweighed by the risk of unfair prejudice, confusing the issues, misleading the jury, wasting time, or needlessly presenting cumulative evidence.

The character or trait may be proved by relevant specific instances of conduct, opinion evidence, and reputation evidence.
Criminal Cases - Evidence of Defendant’s Character
