Evidence Flashcards
Relevance
High
- 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 ([CA] the fact of consequence must be in dispute).
- Legal Relevance: Evidence is legally relevant if it’s NOT excluded: (1) on other policy grounds; AND (2) 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 substantially outweighs the probative value.
California Proposition 8
High
- Under Proposition 8 of the California Constitution, all relevant evidence is ADMISSIBLE in a criminal trial.
- However, such evidence is still subject to balancing: exclusion if the risk of unfair prejudice, confusion of issues, misleading to the jury, or being needlessly cumulative substantially outweighs the probative value.
- 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”).
Subsequent Remedial Measures
Medium
- Evidence of subsequent remedial measures is NOT admissible to show culpability or negligence. [FRE] Evidence of subsequent remedial measures is also NOT admissible in strict products liability cases to prove a defect in a product/design or a need for a warning/instruction.
- However, the court may admit such evidence for other purposes, such as: (i) impeachment; or (ii) to prove a disputed issue as to ownership, control, or feasibility/impossibility of precautionary measures.
- Types of subsequent remedial measures include changes to company rules, installation of safety devices, and postincident discipline or termination of an employee.
Evidence of Liability Insurance
Medium
- Evidence of liability insurance is NOT admissible to prove culpability - that a person acted negligently or wrongfully. However, the court may admit such evidence for another purpose, such as proving bias/prejudice of a witness, or proving agency, ownership, or control.
Offers to Pay Medical Bills
Medium
- Evidence of paying or promising/offering to pay medical expenses or bills is NOT admissible to prove liability (even if there is no disputed claim).
- [FRE] Any related statements or factual admissions (other than the offer to pay) ARE ADMISSIBLE.
- [CA] Related factual statements are NOT admissible.
Offers to Settle
Medium
- Offers to compromise, and statements made during settlement negotiations are NOT admissible to: (a) prove the validity or amount of a disputed claim (the claim must be filed or threatened); OR (b) to impeach by a prior inconsistent statement or contradiction.
- However, the court may admit such evidence for another purpose, such as proving bias/prejudice of a witness, negating a contention of undue delay, or proving obstruction in a criminal matter.
- [CA] Excludes written/oral statements made during mediation proceedings.
Statements of Sympathy
Low
- [CA] Statements of sympathy made to a person or their family are NOT admissible in a civil case as evidence of an admission of liability. Any accompanying statements of fault are admissible.
- [FRE] No such exclusion exists.
Authentication of Evidence: General Rule
High
- 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
High
- 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.
Authentication of Evidence: Voice Recordings
Medium
- Voice recordings may be authenticated by anyone who has (1) heard the person speak (either first hand or electronically); AND (2) identified the recorded person as the speaker.
Best Evidence Rule
High
- 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.
- [CA] This rule is called the Secondary Evidence Rule.
- [FRE] Handwritten duplicates are NOT admissible. [CA] Handwritten duplicates ARE admissible.
Character Evidence
High
- 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.
- BUT character evidence may be offered as circumstantial evidence to prove propensity in certain limited circumstances:
- Defendant’s Character: 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”). [CA] Prosecution can initiate a showing of defendant’s acts of domestic violence or elder abuse.
- Victim’s Character: In criminal cases, 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 ([CA] limited only to violent character trait).
- [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). [CA] No such rule exists.
- 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 to show that the defendant was or was not the source of physical evidence, such as semen or bruises; (b) evidence of sexual relations between the defendant and victim if offered by the defendant to prove consent; or (c) evidence whose exclusion would violate the defendant’s constitutional rights. In a civil case, evidence of the victim’s past sexual conduct or predisposition is admissible only if its probative value substantially outweighs the danger of harm to the victim and unfair prejudice to any party.
- Civil Cases: Character evidence CANNOT be introduced in a civil case to prove propensity, unless the exception for sex-offense cases applies (see above). [CA] There is no exception for sex-offense cases.
- Methods of Proving Character: [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. [CA] The method of proving character is the generally the same as the FRE. There is an exception when the defendant opens the door by offering evidence of the victim’s bad character. In that case, opinion, reputation, and specific acts are admissible in a criminal case on both direct and cross examination to prove the victim’s conduct generally.
Prior Bad Acts
High
- 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.
Habit and Routine Practice
Low
- Evidence of a person’s habit or an organization’s routine practice may be admitted to prove that on a particular occasion the party acted in accordance with the habit or routine practice. The court may admit this evidence regardless of whether it is corroborated or if there was an eyewitness.
- A habit is a regular response to a repeated situation (i.e. going down a stairway two stairs at a time), and usually has four key elements: (1) specificity; (2) repetition; (3) duration; AND (4) is semi-automatic or reflexive. Usually, courts limit habit evidence to behaviors that are semiautomatic or reflexive.
Impeachment: Prior Inconsistent Statements
Medium
- Prior inconsistent statements are admissible to impeach a witness’s trial testimony. A party DOES NOT need to show or disclose the contents of the prior statement when examining a witness on it, but must (on request) show it or disclose its contents to the adverse party’s attorney.
- Extrinsic evidence is admissible only if: (1) relevant to a material issue at trial (one other than the witness’s credibility); AND (2) a proper foundation is shown – (i) the witness is first given an opportunity to explain or deny the statement, and (ii) the adverse party is given an opportunity to examine the witness about it. HOWEVER, the above limitation on extrinsic evidence is not applicable to statements by a party opponent.
- [CA] Extrinsic evidence must be excluded UNLESS: (a) the witness was examined on the subject to give him an opportunity to explain or deny the statement; (b) the witness has not been excused from giving further testimony; OR (c) the interests of justice so require it.
- [CA] A Prior Inconsistent Statement is admissible as nonhearsay when offered only to impeach a witness. If the Prior Inconsistent Statement is offered to prove the truth of the statement, it will be deemed hearsay. However, such evidence is still admissible because a prior inconsistent statement is an exception to the hearsay rule under the California Evidence Code. (Note, a prior inconsistent statement could also be admissible under another hearsay exception, such as if it were a statement by a party opponent).
Impeachment: Prior Convictions
Medium
- [FRE] Evidence of prior convictions may be admitted to attack a witness’s character for truthfulness in certain instances.
- Prior felony or misdemeanor convictions involving dishonesty (a dishonest act or false statement) are ALWAYS admissible to impeach a witness (the judge has no discretion to exclude it). All other misdemeanors are NOT admissible to impeach. A felony is a crime that (in the convicting jurisdiction) was punishable by: (a) death; OR (b) imprisonment for more than one year.
- Felonies that DO NOT involve dishonesty are admissible in the following cases: (1) in a civil or criminal case where the witness is not a criminal defendant (subject to the FRE 403 exclusions); and (2) in a criminal case where the witness is a defendant, but only if the probative value outweighs its prejudicial effect.
- Notwithstanding the above, if 10-years have passed since the later of the witness’s conviction or release from confinement, evidence of the conviction is admissible only if: (1) its probative value substantially outweighs its prejudicial effect and; and (2) proper notice was given.
- [CA] Prior felony convictions involving moral turpitude are ADMISSIBLE to impeach, subject to CEC 352 balancing. Felonies that do not involve moral turpitude are NOT ADMISSIBLE. In a criminal case, misdemeanors are ADMISSIBLE under Proposition 8 for crimes involving moral turpitude (subject to CEC 352 balancing). Otherwise, misdemeanor convictions are NOT ADMISSIBLE. Moral Turpitude is a broad standard, and includes crimes involving lying, violence, sex crimes, and extreme recklessness.
Impeachment: Specific Instances of Conduct
Medium
- [FRE] A witness’s credibility may be attacked on cross-examination by questioning him with specific instances of conduct (i.e. prior bad acts) ONLY IF the conduct is probative of the witness’s character for truthfulness or untruthfulness. However, extrinsic evidence is NEVER admissible to attack or support such instances of a witness’s credibility. Even if a witness lies or denies a specific instance of conduct, he CANNOT be contradicted by extrinsic evidence, such as documentary evidence or by testimony of another witness to show that the witness is lying.
- [CA] Prior bad acts (specific instances of conduct) are generally NOT ADMISSIBLE. However, prior bad acts are admissible under Proposition 8 only if the act(s) involve moral turpitude. In such instances, the use of extrinsic evidence is permitted on cross-examination.
Impeachment: Bias
Low
- A witness’s bias, interest, motive, or partiality is ALWAYS relevant for impeachment. The Supreme Court has held that proof of bias is relevant because the finder of fact (and weigher of credibility) is entitled to assess all evidence which might bear on the accuracy and truth of a witness’s testimony.
- Extrinsic Evidence: Most jurisdictions require that the witness be questioned about the bias before extrinsic evidence of the bias is admissible.
Lay Witness Testimony & Opinions
High
- 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. [FRE] Competency is presumed except for the presiding judge and jurors. [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.
- A lay witness may only offer an opinion if it is: (1) rationally based on the witness’s perception; AND (2) helpful to clearly understand the witness’s testimony or to determine a fact in issue (legal conclusions are not helpful). [FRE] The opinion cannot based on scientific, technical, or other specialized knowledge.
Expert Witness Testimony
High
- Expert testimony is permitted when: (1) the witness is qualified as an expert (by knowledge, skill, experience, training, or education); (2) the testimony is helpful to the trier of fact (if an average layperson/jury could not figure the issue out for themselves); (3) the testimony is based on sufficient facts or data (e.g. documentary evidence, personal knowledge, examination); (4) the testimony is based on reliable principles and methods; AND (5) the expert has reasonably applied the principles and methods to the facts of the case.
- FRE Daubert/Kumho standard: (1) testability; (2) publication and peer review; (3) error rate; (4) standards and controls; AND (5) whether it is generally accepted in the field.
- CA’s Kelley/Frye standard: reliability is based on whether a methodology is generally accepted in the field.
Scope of Cross-Examination
Low
- The scope of cross-examination is limited to: (1) the subject matter of the direct examination; AND (2) matters affecting the witness’s credibility.
Refreshing Recollection
Medium
- Refreshing a witness’s recollection using a document is permitted when (1) the witness once had personal knowledge of the matter, (2) but is unable to recall the matter while testifying [in CA the refreshing may be done prior to or during trial]. When refreshing recollection, the witness will be able to read the document into the record. However, only the opposing party may offer the document into evidence if it is otherwise inadmissible (but it may be admitted by the offering party if admissible under another ground, such as a recorded recollection). The opposing party is also entitled to have the document produced at the hearing/trial, to inspect it, and to cross-examine the witness about it.
