Evidence Flashcards
*Relevance
In order for evidence to be admissible in a court of law, evidence must be both logically and legally relevant.
*Logical Relevance
“Evidence is relevant if it is material to a disputed fact.”
*Legal Relevance
Evidence may be excluded if its probative value is substantially outweighed by danger of unfair prejudice, confusing issues, misleading jury, undue delay, wasting time or being needlessly cumulative.
*California Prop 8
Prop 8 applies to all criminal trials in CA. It is the Victim’s Bill of Rights and provides that all relevant evidence is admissible, subject to balancing, as well as several exceptions. These exceptions include 1) the exclusionary rule; 2) the secondary/best evidence rule; 3) hearsay exclusions; 4) rape shield rules; 5) privilege exclusions; 6) limits on prosecutor offering specific evidence prior to defendant opening the door.
*CA 352 Balancing
When there is a substantial likelihood that the evidence is more prejudicial than probative the court must conduct a balancing test when determining admission, where analysis is similar to the analysis required for legal relevance.
*Policy Exclusions:
- Evidence of insurance against liability is not admissible to show negligence or ability to pay a substantial judgment.
- Evidence of a settlement offer or offers to compromise are not admissible to prove liability for or invalidity of a claim that is disputed as to validity or amount (In CA, discussions and writing during mediation proceedings also not admissible).
- Offers to pay Medical Bills – not admissible to prove liability, even if there is no disputed claim. Under the FRE, related statements of fact are admissible, in CA, they are not.
- Subsequent remedial measures are inadmissible to prove liability but may be used to show ownership or control if disputed (FRE Only – can’t be admitted to prove defective design in a strict products liability case).
Withdrawal of Pleas
A withdrawal of a guilty plea is inadmissible.
Competence and Personal Knowledge
Non-expert witnesses must be competent and have personal knowledge of a matter to testify about the matter. Witnesses cannot be physically or mentally impaired and cannot be too young to understand the oath and the need to testify truthfully. Competence is presumed in the CA evidence code.
*Authentication
A party must prove the item it seeks to admit is actually what the party purports it to be. Evidence can authenticated via witness testimony or evidence of holding in a substantially unbroken chain of custody.
Vocal Recognition
A voice may be identiied by the opinion o anyone who has heard the voice at any time, even the same day or during curent trial proceedings
Signature Recognition
A jury can verify the authenticity off fa signature with an appropriate example to compare.
*Best Evidence Rule
A party must provide the original document when testifying to contents of a writing. A photocopy is an acceptable substitute. Oral testimony is allowable only after showing original is not available for some reason other than misconduct. In CA called the Secondary Evidence Rule. CA accepts duplicates and hand-written evidence of the contents of an original document.
Character Evidence
Evidence of a person’s character is not admissible to show propensity, but may be admissible for other purposes, such as when character is at issue (defamation, etc), or for impeachment purposes.
Defendant’s Character
In criminal cases, a defendant has a right to provide evidence of their own character, but once they do, they have “opened the door” to cross examination regarding character by the prosecution
Victim’s Character
A defendant may provide evidence of the victim’s character to prove the defendant’s innocense, except in cases which involve rape. Prosecution may counter this by showing victim’s good character for the same trait, or the defendant’s bad character for the same trait. This applies only to violent traits in CA.
Method of admission
FRE - When character evidence is admissible, it can be proven by opinion or reputation testimony, or, if done during cross, specific acts.
CA - The defendant’s character can only be proven by opinion or reputation. The victim’s character can be proven by opinion, reputation or specific acts
404(b) Prior Bad Acts
Evidence of any other crime, wrong, or act is not admissible to prove a perston’s character in order to show that on a particular occasion, a person behaved in accordance with that character. However, the evidence may be admissible for other purposes, such as proving motive, opportunity, intent, preparation, planning, knowlege, identity, absence of mistake, or lack of accident (MOPPIKIAL)
Prior Convictions
Felony or misdemeanor convictions involving dishonesty are always available to impeach. Felonies not for dishonesty have a 10-year limit from the latter of convition or release from confinement. Requires probative value/prejuicial evvect determination, an proper notice.
CA- Admission requires CEC 352 balancing for moral turpitue crimes, and misemeanors are admissible under Prop 8
Prior Inconsistent Statement
These statements are admissible to imeach. Extrinsic evidence is admissible only if relevant to a material issue, and proper foundation is laid.
CA - A prior inconsistent statement is amissible as non-hearsy when oered only to imeach a witness, and wehther or not under oath
Witness Competence
FRE - All witnesses are assumed to be competent.
CA - All witnesses must unerstand that they have a duty to tell the truth
*Lay Witness
A lay witness is any person that is not an expert. They must take an oath to tell the truth, and have capacity to perceive, recall and communicate. They may offer an opinion if it is rationally based on the witness’ perception and it is helpful to the jury. Lay witness testimony cannot be based on specialized or scientific knowledge.
*Expert Witnesses
Expert testimony is appropriate only when the subject matter is one where scientific, technical, or other specialized knowledge would assist the trier of fact. The witness must believe the opinion, which must be supported by fact and based on reliable principles.
Expert witnesses In CA, Kelley/Frye Standard
The opinion must be based on principles generally accepted by experts in the field
Expert witnesses In CA, Daubert/Kumho Standard
Reliability is determined by publication, peer review, error rate, results are tested and have an ability to retest, and reasonable level of acceptance in the community.
