Evidence Admissibility

Relevance

Authentication

Admissibility

direct vs circumstantial evid
Direct vs. Circumstantial Evid
  • Direct evidence: statement by witness of direct sensory observation
    • Proves existence of some fact without inference or presumption
  • Circumstantial evidence: evidence from which the proof of a material fact is inferred
    • Not based on witness’ personal knowledge
    • Additional reasoning required to reach proposition to which inference is directed
relevance fre rule 401
Relevance: FRE Rule 401

Definition of ‘‘Relevant Evidence’’

  • ‘‘Relevant evidence’’ means evidence having any tendency to make the existence of any fact that is of consequence to the determination of the action more probable or less probable than it would be without the evidence.
relevance fre rule 402
Relevance: FRE Rule 402

Relevant Evidence Generally Admissible; Irrelevant Evidence Inadmissible

  • All relevant evidence is admissible, except as otherwise provided by the Constitution of the United States, by Act of Congress, by these rules, or by other rules prescribed by the Supreme Court pursuant to statutory authority. Evidence which is not relevant is not admissible.
relevance rule 403
Relevance: Rule 403

Exclusion of Relevant Evidence on Grounds of Prejudice, Confusion, or Waste of Time

  • Although relevant, evidence may be excluded if its probative value is substantially outweighed by the danger of unfair prejudice, confusion of the issues, or misleading the jury, or by considerations of undue delay
  • Relevant evid excluded if prejudicial, balaincing probative value against harm likely
    • EX: emotional, time waste
relevance
Relevance
  • Trial court judges have wide lattitude
    • Subject to trial attorney exceptions & appeal
    • Object to admission as arguably irrelevant
    • Object to exclusion because arguably relevant
  • Relevance vs. Materiality
    • Relevance: evidence is relevant to a proposition or point
    • Materiality: proposition or point is material to an issue at trial, has legal significance to case
    • EX: electric lawn mowing, wet grass & bare feet-relevant to contributory negligence
      • Immaterial if issue at trial is thrown broken blade
    • FRE Now Merges Materiality into Relevance
relevance1
Relevance
  • Relevance is not inherent but contextual
  • Exists only in relation between item of evidence & matter requiring proof
    • Either in witness’ Experience or from Science
    • Applied logically to factual proposition
authentication
Authentication
  • FRE Rule 901. Requirement of Authentication or Identification
    • (a) General provision.—The requirement of authentication or identification as a condition precedent to admissibility is satisfied by evidence sufficient to support a finding that the matter in question is what its proponent claims.
    • A/K/A “Laying the Foundation”
  • Test: sufficient proof that a reasonable juror could find authentic
    • eVid inadmissible as not authentic if source of info or method or circumstances of preparation lacks trustworthiness
why authentication
Why Authentication?
  • Cannot accept proffered evid at face value
    • Exception for Self-Authentication
  • Initial proof of accuracy & not forgery
    • Judge rules, opposing counsel may move
    • Particularly important for exhibits & docs (e-)
    • But there is no guarantee against fabrication
    • Ultimately an outcome of adversarial trial process
  • Authentication defined:
    • Genre, verifying authorship, integrity, completeness, correctness, validity, faithfulness to original, meaningfulness, suitability for intended purpose
authentication how
Authentication How?
  • Accomplished in Pre-Trial Discovery
    • Request for Admission of genuineness
    • Stipulation
    • Production authenticates as to claimed status
    • Interrogatory
    • Deposition
    • FRCP 26(a) list not objected to
authentication how1
Authentication How?
  • Accomplished at trial
    • Request: marked for identification as Exhibit#
    • Witness sponsored
    • Offering as exhibit
    • Permitting adverse counsel to examine or object
    • Submitting to judge requesting to examine
    • Court ruling on admissibility
    • Permitted jury to hear it read, displayed or passed to
authentication how fre rule 901 b some exs
Authentication How? FRE Rule 901(b) Some EXs
  • Testimonial sponsor with knowledge
  • Chain of Custody
  • Handwriting (lay vs. expert opinion)
  • Distinctive characteristics (ltr-head)
  • Voice ID
  • Telephone calls
  • Public reports & records
  • Ancient Documents
  • Tape Recording
  • Photos, Videotapes, Xrays
  • Computer Output
chain of custody
Chain of Custody
  • Authentication, Foundation or Predicate
    • Addresses implication & risk that broken chain suggests opportunities for falsification, alteration, deterioration, mis-ID or tampering
    • Typically triggered by objection to admission where chain allegedly broken or uncertain
  • Most useful for fungible evid, lack distinctive characteristics
    • EX: counterfeit currency, car key, computer file
    • Not normally necessary if identifiable by distinctive
chain of custody1
Chain of Custody
  • Factors in chain of custody
    • Potential commingled items w/ similar appearance
    • Sponsor failed to ID uniquely &/or adequately record
  • Establishing Chain from Seizure to Production
    • Witness describes initial recovery of item(s)
    • Others describe handling, transfer & receipt
    • Precautions taken to preserve evid
    • Proof item not changed, substituted or tampered
    • Each, as link in unbroken chain, testify to chain’s integrity & item’s unchanged condition
      • Not all breaks require inadmissibility: seriousness & reasonability of safeguards
chain of custody edd
Chain of Custody: EDD
  • eData easily altered, files appear fungible
  • Chain of Custody eData Log is Crucial:
    • Every step documented throughout process
    • Proper copying, transporting & storage
    • Demonstrates that no alteration occurred
    • All media secured throughout
hearsay
Hearsay
  • Hearsay Rule: Oral or Written Hearsay is Inadmissible

    • ‘‘statement’’ is (1) an oral or written assertion or
    • (2) nonverbal conduct of a person, if it is intended by the person as an assertion.
    • Includes eData, some non-verbal
  • FRE 802. Hearsay Rule
    • Hearsay is not admissible except as provided by these rules or by other rules prescribed by the Supreme Court pursuant to statutory authority or by Act of Congress.
  • Prohibits witness from relating the word of another person w/o exceptional circumstances
hearsay rationale
Hearsay Rationale
  • Reasons: Reliability Generally Untestable
    • Unreliability of out of court declarant cannot be tested by confrontation & cross-exam
      • Perception
      • Memory
      • Sincerity
      • Narration
    • Confrontation Cl, 6th A.
      • In all criminal prosecutions, the accused shall enjoy the right … to be confronted with the witnesses against …
hearsay exceptions
Hearsay Exceptions
  • Major Exceptions:
    • Not Hearsay: not offered for truth of contents
      • EX: offered to prove only that something was said (defamation) such as effect on listener or reader
    • Excited Utterance
    • Dying Declaration
    • Business records
  • Reasons:
    • Specific to each exception, but generally heightened reliability & lower risks over general hearsay risks of memory, perception, sincerity & narration
burden of proof
Burden of Proof
  • Burdens: proof= production/going forward + persuasion
    • “tipping point” to adjudicate in favor of one or other party
  • Civil: Plaintiff
    • Preponderance
    • Sometimes: clear & convincing, greater weight
  • Criminal: Prosecution
    • Beyond Reasonable Doubt
  • Defendant: any/all defenses
  • Appeal: arbitrary, unreasonable, capricious
    • Evid admission/exclusion: abuse of discretion
    • Regulatory: unsupported by “substantial evid”

  • Formal Daubert hearings not always necessary
  • Kumho too difficult for judges to distinguish scientific from other technical disciplines
