Evidence Flashcards
Relevance
Evidence must be relevant to be admissible. Relevant if:
- Probative of (making more or less likely)
- A material fact
FRE 403
- A judge may use their discretion to exclude evidence if the probative value is significantly outweighed by danger of:
- Unfair prejudice
- Confusion of the evidence
- Misleading the jury
- Undue delay/waste of time, or
- Needless presentation of cumulative evidence
Public policy exclusions
- Subsequent remedial measures
- Settlement offers or negotiations
- Offers to pay medical expenses
- Plea negotiations
- Liability insurance
- Sexual conduct
Subsequent remedial measures
- Evidence that D took precaution after injury occurred
-
Inadmissible to show:
- Liability
- Fault
- Defect in product
-
Admissible to show:
- Impeachment
- Feasibility of repair
- Ownership/control (if in dispute)
Settlement offers/negotiations
- Evidence that D took precaution after injury occurred
-
Inadmissible to show:
- Liability
- Validity of claim
- Amount of a claim
- Impeachment by prior inconsistent statement
-
Admissible to show:
- Impeachment by bias
Offers to pay medical expenses
-
Inadmissible to show:
- Liability for injuries
- BUT: Statements or conduct accompanying the offer may be admissible
Plea negotiations
- Not admissible (too prejudicial)
-
Includes:
- Withdrawn guilty please
- Nolo contendere please
- Offers to plead guilty
- Statements made while negotiating a plea
Past sexual conduct of the victim
-
Criminal cases: generally not admissible in cases involving sexual misconduct. Exceptions:
- Show that D was/was not the source of physical evidence (bruises, semen)
- Show V’s past sexual conduct with D to show consent
- Other circumstances in which exclusion would violate D’s due process
-
Civil cases: generally not admissible, unless probative value substantially outweighs harm to V/prejudice to a party
- Evidence of reputation is admissible only if V brings it up.
Past sexual conduct of defendant
In either a criminal or civil case in which a defendant is accused of committing an act of sexual assault/child molestation, evidence that the defendant committed any other sexual assault or child molestation is admissible to prove any relevant matter.
Note: c.f. character evidence/specific bad acts.
Character evidence (civil case)
Inadmissible to prove conduct in conformity with that character trait
- Except if character is an essential element of the claim or defense (e.g., defamation)
- Except if proving past sexual assault in a sexual assault case
But prior bad acts may be admissible for non-character purpose
Character evidence (criminal case)
-
Character of defendant inadmissible to prove propensity
- Except D may “open the door” by introduce reputation or opinion evidence of her good character
- Prosecution may rebut D’s evidence with character evidence about the same trait
-
Character of victim (V): D may introduce reputation or opinion to prove a defense
- Prosecution may rebut with reputation, opinion or specific acts evidence
- Prior sexual conduct of V is admissible to show that someone else is the source of physical evidence OR to prior relationship → consent
Prior bad acts
“MIMIC” evidence resembles character evidence but is admissible to show purposes other than propensity:
- Motive
- Intent
- Absence of Mistake
- Identity (or signature modus operandi)
- Common plan
Causes of action/defenses where character is at issue
- Defamation (defend by truth of defamatory statement)
- Negligent hiring
- Negligent entrustment
- Child custody (fitness to parent)
- Self defense (reasonable belief of deadly harm)
- Entrapment (D did not have predisposition to commit crime; rebuttable by P)
Habit evidence
A semi-automatic response to a specific and frequent situation. May resemble character evidence, but is admissible:
- For an organization, a habit is a routine practice of the org.
- Look for multiple past occurrences, language like “always,” “every day,” “frequently,” “instinctively”
Impeachment by prior conviction
Consider both timing and type.
-
Timing:
- Within 10 years: admissible
- > 10 years: probative value must significantly outweigh prejudice and proponent must give adverse party advance notice
-
Type (subject to 10 year restriction):
- Crimes involving dishonesty: admissible
- Other misdemeanor: not admissible
-
Other felony (punishable by > 1 year in prison):
- Of a witness: admissible
- Of criminal D: only admissible if P shows that probative value outweighs prejudice to D
Note: For any “admissible,” note that 403 balancing will always apply.
Methods of impeachment of a witness
- Dishonest character or prior criminal conviction
- Prior inconsistent statements
- Bias
- Sensory deficiency
Requirements for tangible evidence
Tangible evidence: documents and physical objects (c.f. testimony evidence)
- Authentication
- Best evidence rule
- Parol evidence rule
Authentication
Establishing that the item is genuine and what the proponent claims it to be. Generally requires W’s firsthand knowledge or familiarity
-
Physical objects includes weapons, injury, models, photos, X-rays, incident scene, demos. Authenticate by
- Testimony
- Distinctive characteristics, or
- Chain of custody
-
Documents: authenticate by
- Stipulation
- Testimony, or
- Handwriting verification by comparing to another genuine item or by lay opinion
- Self-authenticating documents include certified/public/official records, periodicals, ancient documents (20+ years old)
- Oral statements: authenticate identity of the speaker by testimony
Best evidence rule
When attempting to prove the contents of a writing, recording, or photograph, the original document or a reliable duplicate must be produced.
-
Exceptions: The original is not required if it is unobtainable, lost or destroyed, opposing party refuses to produce it, or it regards a collateral matter.
- Exception does not apply if lost or destroyed by the proponent in bad faith
- Copies of public records must be certified
- Alternative proof: allowed for public records, voluminous records and party admission
Note: does not apply if merely proving the existence of a document.
Parol evidence rule
Bars extrinsic evidence of prior or contemporaneous statements that contradict the written agreement (if integrated agreement).
- Integrated writing: intended as final expression of the parties’ agreement; partial okay
- Extrinsic evidence allowed to attack validity or explain terms
Refreshed recollections
-
Present recollection refreshed:
- Testifying witness can refresh memory by looking at any evidence
- Document itself is offered into evidence)
-
Past recollection recorded:
- Testifying witness once had personal knowledge of…
- But now cannot recall well enough (refreshing attempted and fails)
- Was made or adopted by W when the matter was fresh in memory, and
- Accurately reflects W’s knowledge
- Testimony admissible by hearsay exception
- Document not admitted unless adversary introduces to evidence file
- Testifying witness once had personal knowledge of…
Opinion testimony
-
By a lay witness: generally not allowed, unless:
- To prove common sense impressions e.g., appearance, intoxication, speed, handwriting
- If based on W’s perception and helpful to clarify understanding of the issue
-
Expert: allowed if scientific, technical, or specialized testimony will help the trier of fact, and:
- Qualified by knowledge, skill, training, experience, or education
- Based on sufficient facts or data personally observed or made aware of (need not be admissible)
- Product of reliable methods reasonably relied on by experts in the field
- Applied the methods and principles reliably to the facts and
- Reasonably certain in her opinion (probably true, no guessing).
- May embrace ultimate issue but not criminal defendant’s mental state
Reliability factors (expert testimony)
- Generally accepted in relevant scientific community,
- Peer reviewed (capable of retesting),
- Published,
- Low error rate
Evidentiary privileges
- Spousal
- Immunity
- Marital communications
- Attorney-Client
- Physician-Patient
- Psychotherapist-Patient
