EVIDENCE Flashcards
Relevance (Logical & Legal Relevance)
To be admissible, evidence must be relevant. Evidence must be both logically AND legally relevant.
Logical Relevance: Evidence is LOGICALLY relevant if: (1) it has any tendency to make a fact more or less probable than it would be without the evidence; AND (2) the fact is of consequence in determining the action (in CA the fact of consequence must be in dispute).
Evidence is LEGALLY relevant if it’s NOT excluded: (1) on other policy grounds; AND (2) under FRE 403/CEC 352.
Under FRE 403/CEC 352, the court may exclude relevant evidence if its probative value is substantially outweighed by a danger of: (a) unfair prejudice; (b) confusing the issues; (c) misleading the jury; (d) undue delay; (e) wasting time; OR (f) being needlessly cumulative.
California Proposition 8
Under Proposition 8 of the California Constitution, all relevant evidence is ADMISSIBLE in a criminal trial.
In addition, Proposition 8 does not affect the following:
(1) exclusionary rules based upon the U.S. Constitution;
(2) the secondary/best evidence rule;
(3) hearsay exclusions;
(4) privilege exclusions;
(5) evidence barred under rape-shield statutes;
(6) limits on prosecution from offering specific character evidence (prior to defendant “opening the door”).
However, such evidence is still subject to CEC 352 balancing (whether the probative value is substantially outweighed by the risk of unfair prejudice, confusion of issues, misleading to the jury, or being needlessly cumulative).
Authentication of Evidence Physical and Documentary Evidence–General Rule
All evidence MUST be authenticated before being admitted into evidence. A party must prove that the item it seeks to admit is actually what the party purports it to be, UNLESS the parties stipulate otherwise.
Authentication of Evidence–Physical Evidence
Physical evidence may be authenticated through:
(a) witness testimony; OR
(b) by evidence that shows it has been held in a substantially unbroken chain of custody.
Best Evidence Rule
- Under the Best Evidence Rule, a party must provide the original document (or a reliable duplicate) when a witness (a) testifies to the contents of a writing; OR (b) testifies to knowledge gained solely from a writing.
- Under the FRE, handwritten duplicates are NOT admissible. In CA, handwritten duplicates ARE admissible.
Character Evidence–In General
Generally, evidence of a person’s character is NOT admissible to show propensity (that on a particular occasion the person acted in conformity with the character trait). HOWEVER, character evidence is generally admissible for any non-propensity purpose, such as when character is an ultimate issue in a case (i.e. defamation) or to impeach.
• Notwithstanding the above, character evidence may be offered as circumstantial evidence to prove propensity in certain limited circumstances (see other cards).
Character Evidence–Defendant’s Character in Criminal Cases (General Rule)
In criminal cases, a defendant may always introduce evidence of his own character. The prosecution is NOT allowed to present evidence of the defendant’s character to prove propensity UNLESS the defendant first presents evidence of his own character (the defendant “opens the door”).
▪ In CA, the prosecution can initiate a showing of defendant’s acts of domestic violence or elder abuse.
Character Evidence–Victim’s Character in Criminal Case
Except in cases involving rape, a defendant may offer evidence of the victim’s character to prove the defendant’s innocence. If the defendant presents such evidence, the prosecution may present evidence of the: (a) victim’s good character for the same trait; or (b) defendant’s same bad character trait (in CA it is limited only to violent character trait).
Character Evidence–Homicide Case
Under the FRE, in a Homicide Case the prosecution may offer evidence of the victim’s character for peacefulness ONLY IF the defendant claims the victim was the aggressor (self-defense). In CA, no such rule exists.
Character Evidence–Sex-Offense Cases
For Sex-Offense Cases involving alleged sexual misconduct, evidence offered to prove a victim’s sexual behavior or predisposition is generally NOT admissible. However, certain exceptions to this rule exist.
In a criminal case, the court may admit: (a) evidence of specific instances of a victim’s sexual behavior if offered to prove that the defendant was not involved in the sex crime; (b) evidence of sexual relations between the defendant and victim if offered (i) by the defendant to prove consent, or (ii) by the prosecutor for any reason; and (c) evidence whose exclusion would violate the defendant’s constitutional rights.
Character Evidence–Civil Cases
Character evidence CANNOT be introduced in a civil case to prove propensity, unless the exception for sex-offense cases applies (child molsetation and sexual assault).
In CA Civil Cases, there is no exception for sex-offense cases.
Character Evidence–Methods of Proving DEFENDANT’S Character
o Under the FRE, when character evidence is
admissible, it may be proven in the following ways: (1) on direct examination by opinion testimony or testimony of reputation in the community; OR (2) on cross examination of the character witness by opinion, reputation, or specific acts.
o In CA, the DEFENDANTS’s character may only be proven by opinion or reputation.
Character Evidence–Methods of Proving VICTIM’S Character
A VICTIM’s character may be proven by opinion, reputation, or specific acts.
Prior Bad Acts
Evidence of prior bad acts (crimes, wrongs, or acts) is NOT admissible to show propensity (that on a particular occasion the person acted in conformity with a character trait).
• However, evidence of prior bad acts may be admissible for other relevant non-propensity purposes, such as proving Motive, Identity, Absence of Mistake or Accident, Intent, a Common Plan or Scheme, Opportunity, or Preparation. (MIMIC)
Lay Witness Testimony–In General
A lay witness is any person who gives testimony in a case that is NOT called as an expert. A lay witness’s testimony is admissible if he is competent to testify.
To be competent, the witness must: (1) take an oath to tell the truth; AND (2) have the capacity to perceive, recall, and communicate. Additionally, a witness may only testify to matters of which he has personal knowledge.
o Under the FRE, competency is presumed except for the presiding judge and jurors.
o In CA, in addition to the above competency factors, the witness must also understand the legal duty to tell the truth. Also, the presiding judge and jurors may testify if there is no objection.
