Evidence Flashcards
Relevant evidence
Has any tendency to make the existence of any fact of consequence to the determination of the action more probable or less probable than it would be w/o the evidence. Components of relevance:
-(1) Material
-(2) Probative
General rule of admissibility:
-Irrelevant evidence is always inadmissible
-Relevant evidence is admissible unless (1) kept out by some evidence rule (e.g. hearsay), or (2) court uses Rule 403 discretion to exclude it.
Rule 403 discretion
Judge has discretion to exclude [relevant] evidence if its probative value is substantially outweighed by the danger of any of the following considerations:
-Unfair prejudice
-Confusion of issues (evidence creates some side issue)
-Misleading jury (jury gives it undue weight in deliberations)
-Undue delay
-Waste of time
-Cumulative
Prior similar occurrences
Generally inadmissible (usually under 403), but some exceptions:
-P’s accident history –> may be admissible to show something other than carelessness. Prior false claims to prove present claim is false; prior accidents involving same body part when causation at issue.
-Similar accidents caused by same event or conditions (other accidents involving the D): admissible to prove existence of dangerous condition; causation; notice to D [of dangerous condition] if those events occurred before the accident in question.
-Absence of similar accidents: evidence of the absence of complaints is admissible to show D’s lack of knowledge of the danger.
-Previous similar acts admissible to prove intent: party’s similar conduct admissible to show their intent in current case.
-Sales of comparable property: admissible to establish property’s value.
-Rebut claim of impossibility: similar occurrences admissible to rebut claim that occurrence at issue was not possible.
-Habit or business routine of an org: admissible as circumstantial evidence that person/org acted in accordance with habit on occasion.
-Habit: regular response to specific set of circumstances.
-Industry custom evidence: admissible as evidence of appropriate standard of care (how D should have acted).
Public policy exclusions to admissibility of evidence
-Liability insurance: inadmissible to prove negligence/wrongful conduct. But admissible to prove ownership or control, if disputed; to impeach a witness.
-Subsequent remedial measures: inadmissible to prove negligence, culpable conduct, defect, or need for warning or instruction. May be admissible for other relevant purpose, like to prove ownership or control, if disputed; to rebut a claim that the precaution was not feasible/that the product couldn’t be made safer; or to prove that the opposing party has destroyed evidence.
-Civil settlements and settlement negotiations: settlements, offers, and conduct or statements in negotiations (incl. statements made during negotiations) inadmissible to: prove validity or amount of claim; impeach by prior inconsistent statement or contradiction (but impeachment with bias permitted).
-Disputed claim required: evidence excluded only if claim/indication of claim disputed as to validity OR amount. So need an actual claim and a dispute b/w the parties.
-Limited exception: conduct or statements in civil negotiation with government/regulatory authority admissible in criminal case.
-Plea discussions. The following are inadmissible: offers to plead guilty; withdrawn guilty pleas; no-contest pleas; statements in plea discussions. But D can waive these as long as knowing and voluntary.
-Payments of and offers to pay medical expenses / offers of compromise: inadmissible to prove liability, but accompanying admissions of fact are admissible (e.g. I’d like to give you $1k for your medical bill. I’m sorry I ran the red light” –> second sentence is admissible). Don’t need a disputed claim.
-But offers to settle are NOT admissible. E.g. “I’ll pay your medical bills if you drop the case”–> more restrictive rule applies, so this is inadmissible.
-Statements made in connection with an offer to pay medical expenses, unlike statements made in connection with a settlement offer, are admissible.
Character evidence (definition)
Evidence that refers to a person’s general propensity or disposition (e.g. honesty, peacefulness, violence). Purposes for offering character evidence:
-Prove person’s character when directly in issue (rare)
-Prove how person probably acted (conduct in conformity/propensity evidence) (common)
-Impeachment (character evidence about party’s truthfulness).
Methods of proving character:
-Specific acts
-Opinion testimony
-Reputation testimony
D’s character in criminal case
-Prosecution can’t initiate, but D can raise evidence of good character to prove evidence. If D does, opens the door to prosecution rebuttal. But D’s simply testifying does NOT open the door to general character evidence.
-D can prove by reputation and/or opinion testimony concerning pertinent trait; but CANNOT bring in specific instances of conduct and cannot be about an impertinent trait.
Prosecution’s options once D has opened the door:
-X D’s character witnesses: “Have you heard?’; “Did you know?” –> can test CW’s knowledge about specific instances of past misconduct that relates to the character trait at issue.
-Call own character witnesses –> but can’t follow up with external evidence to counter the witnesses’ answers.
D’s character in civil case
Generally inadmissible to prove conduct in conformity (regardless of which party is trying to bring in the evidence), i.e. it cannot be offered to prove how a person probably acted during the events of the current case.
-If not being offered for propensity, can go in.
Admissible (reputation, opinion, specific act evidence) only when directly in issue. Rare and generally limited to:
-Defamation cases, where truth is a defense
-Negligent hiring or entrustment cases, where the person hired or entrusted’s character is an element and has to be proved.
-Fraud causes (D’s character)
-Child custody cases, where the parent’s character is an issue to see what’s in the best interest of the child in terms of custody arrangement.
Victim’s character in criminal case
Initiated by D: D can offer reputation and/or opinion testimony concerning victim’s character for relevant trait (usually propensity to violence to support D’s self-defense claim).
Pros rebuttal: after D introduces evidence about victim, pros can rebut with reputation and/or opinion testimony concerning:
-Victim’s good character for same trait
-D’s bad character for same trait
Victim’s character in homicide case
Initiated by P: in (1) homicide case (2) if D claims self-defense, evidence of ANY KIND that victim was first aggressor opens door to evidence of victim’s good character for peacefulness.
Victim’s character in sexual assault cases
Victim’s past sexual behavior generally inadmissible, except:
-In criminal cases to prove different of injury or physical evidence or to show consent b/w victim and D.
-In civil cases when probative value substantially outweighs unfair prejudice (displaces Rule 403; cooked in favor of excluding evidence).
Other misconduct for non-character purpose
Person’s other misconduct generally inadmissible if offered solely to prove conduct in conformity/propensity. But only admissible if D is actually contesting the non-character issue.
-Possibly admissible if offered for some independently relevant purpose (NOT character or propensity to commit crime).
-Common non-character purposes: motive; intent; mistake (absence of); identity (e.g. D has a signature way/MO of committing a crime and you can link previous signature to current crime); common plan or scheme.
Under Federal Rule 404(b), independently relevant uncharged misconduct by the defendant will be admissible, without a preliminary ruling, as long as there is sufficient evidence to support a jury finding that the defendant committed the prior act.
-But prior misconduct evidence is inadmissible if the danger of unfair prejudice substantially outweighs the probative value.
-If P offering this kind of evidence, must give D timely notice in advance of trial.
D’s similar misconduct in sex crime cases
D’s other similar acts are admissible for any relevant purpose (even to show propensity to engage in sex crimes) in criminal or civil case involving alleged sexual assault or child molestation.
Authentication
As a general rule, a writing or any secondary evidence of its content will not be received in evidence unless the writing is authenticated [by proof that the writing is what the proponent claims it is].
-Proof must be sufficient to support jury finding of genuineness.
Methods of authentication:
-Opponent’s admission
-Eyewitness testimony of someone with knowledge
-Handwriting verifications, e.g. lay opinion on handwriting (if lay witness has pre-existing knowledge).
-Expert opinion on handwriting
-Jury comparison of handwriting
Ancient documents
Document can be authenticated if:
-At least 20 years old,
-In non-suspicious condition, and
-Found in place where such a writing would likely be kept.
Corresponding hearsay exception applies to documents older than 1998.
Reply letter doctrine
Document can be authenticated by evidence it was written in response to communication sent to alleged author.
Authentication of photographs and videos
Must be identified by witness as fair and accurate representation of facts depicted.
-Generally, photographer/filmer need not testify.
Unattended camera: photograph/camera admissible if camera was properly operating and photograph/video came from that camera.
X-rays
Unlike photos, an x-ray cannot be authenticated by testimony of a witness that it is a correct representation of the facts. It must be shown that the process used was accurate: the machine was in working order and the operator was qualified to operate it. Last, custodial chain must be established to show the x-ray was not tempered with.
Authentication of oral statements
Admissible only if said by a particular person, need to authenticate the speaker:
-Voice ID: voice can be identified by any person who has heard the voice at any time (even after litigation has begun and for the sole purpose of testifying).
Telephone conversations: statements authenticated in following ways:
-Party to call recognized speaker’s voice.
-Speaker had knowledge of certain facts.
-Speaker answered phone number and identified themselves or their residence.
-Speaker who answered business’s phone talked about business matters.
Self-authenticating documents
-Domestic public docs with seal
-Official publications
-Certified copies of public records or private files on record at public office
-Newspapers and periodicals
-Trade inscriptions and labels
-Acknowledged (notarized) docs
-Commercial paper
-Business records and electronically generated records w/ certification and notice
Best Evidence Rule
To prove content of a writing, recording, or photograph (including videos), the original must be produced if the terms of the writing are material.
-Secondary evidence admissible only if proponent has good excuse for not producing original.
When best evidence rule applies (2 main situations):
-Where writing is legally operative or dispositive
-Where witness’s knowledge results from having seen the writing/video/etc. E.g. only proof of break in was security guard seeing burglar on security camera and trying to testify on it –> objectionable, need original.
Original: writing itself, or any counterpart intended to have same effect; negatives of photos or prints of those; print out of original from computer.
Duplicate: exact copy made by mechanical means (note: handwritten copies are NOT duplicates). Admissible to same extent as original, unless either:
-Circumstances make it unfair to admit duplicate (e.g. it’s a bad copy), or
-Genuine issue raised as to authenticity of original
When does the rule NOT apply?
-When a witness has personal knowledge of the facts in the writing.
-A party may introduce other evidence of the doc’s content (e.g. via testimony) when a party against whom the original would be offered had control of the original, was put on notice that the original would be a subject of proof at trial, AND failed to produce the original at trial.
Jury’s role in evaluating best evidence:
-Whether the original ever existed
-Whether a writing produced at trial is or is not an original
-Whether the evidence offered correctly reflects the contents of the original
Admissibility of secondary evidence of content
If the proponent cannot produce the original or an admissible duplicate, they may offer secondary evidence of its content, such as handwritten copies, notes, or oral testimony if a satisfactory explanation is given for the non-production of the original. Satisfactory explanations/excuses:
-Original lost or destroyed (unless proponent destroyed in bad faith, e.g. shredding in the dark of night)
-Original cannot be obtained (e.g. in possession of a third party abroad).
-Original in possession of adversary who fails to produce it.
Exceptions to best evidence rule
-Summaries of voluminous records
-Certified copies of public records
-Collateral writings (of minor importance to the matter in controversy)
-Opponent testified or gave written admission about contents of writing
