Evidence Flashcards
relevance
evidence is relevant if it has any tendency to make material fact more probable or less probable than would be the case without the evidence
all evidence is admissible unless
some exclusionary rule applies OR the court makes a discretionary determination that the probative value of the evidence is substantially outweighed by pragmatic considerations such as: danger of unfair prejudice confusion of the issues misleading the jury undue delay waste of time unduly cumulative
plaintiffs accident history
generally inadmissible because it is character evidence but it is admissible if the event that caused the plaintiff’s injury is at issue
ex. did the car accident or an earlier accident cause the injury
defendant’s accident history
inadmissible because nothing more than character evidence BUT other accidents involving the same instrumentality or condition may be admitted for 3 potential purposes if the other accident occurred under substantially similar circumstances
- existence of a dangerous condition
- causation of the accident
- prior notice to the defendant
intent at issue
prior similar conduct of a person may be admissible to raise an inference of the persons intent
ex. can show instances of past discrimination
comparable sales on issue of value
selling price of other property of similar type in a same general location and close in time period at issue is some evidence of value of the property at issue
Habit
habit of a person or business is admissible as circumstantial evidence of how the person acted on the occasion at issue
a repetitve response to a particular set of circumstances with 2 defining characteristics
1. frequency of conduct
2. particularity
this is distinguished from character evidence which refers to a person’s general disposition or propensity, habit is more probative
industrial custom as standard of care
evidence as to how others in the same trade or industry have acted in the recent past may be admitted as some evidence as to how a party in instant litigation should have acted (as evidence of the appropriate standard of care)
liability insurance
evidence that a person has or does not have liability insurance is inadmissible for the purpose of showing fault or absence of fault.
Policy: to avoid risk that jury will base decision on availability of insurance instead of merit of case
EXCEPTION: evidence of insurance may be admissible for some other relevant purpose such as proof of ownership or control if disputed by the D or for the purpose of impeachment of a witness
subsequent remedial measures
post accident repairs, design changes, policy changes are inadmissible for the purpose of proving negligence culpable conduct product defect need for warning
Policy: to encourage post accident repairs
Exception: can be admissible for some other relevant purpose such as proof of ownership/control or feasibility of safer condition if disputed by the D
OHIO: in product liability based on strict liability, the manufacturers subsequent remedial measures are admissible to show the existence of a defect in the product at the time of the accident
settlement of disputed civil claims
settlement, offer to settle, and statements of fact made during settlement are inadmissible for the purpose of liability or impeaching a witness for prior inconsistent statements
policy: to encourage settlement
Exceptions: to impeach a witness for bias
statements of fact made during settlement negotiations in civil litigation with a government regulatory agency are admissible in a later criminal action.
in OHIO: government agency exception is not adopted
plea bargaining in criminal cases
inadmissible:offer to plead guilty, withdrawn guilty plea, plea of nolo contendere
admissible, guilty plea not withdrawn
Ohio: a conviction based on a plea of no contest can be used in two limited situations:
1. as an enhancement factor for a crime that is made more serious by statute, the D’s prior convistion and
2. in administrative proceedings in which a prior conviction by statute can serve as the basis for revocation of a license
offer to pay hospital or medical expenses
inadmissible to prove liability but the rule does not exclude other statements made in connection with an offer to pay hospital or medical expenses
character evidence
3 potential purposes for the admissibility of character evidence
- persons character is an essential element of the case, the substantive law requires proof of character
- character evidence to prove conduct in conformity with character at the time of the litigated event aka character as circumstantial evidence of conduct
- witness’s bad character for truthfulness to impeach credibility
criminal cases: character evidence
evidence of the D’s character is not admissible during the prosecutions case in chief
the D during the defense may introduce evidence of a relevant character trait by reputation or opinion to prove conduct in conformity thereby opening the door to rebuttal by the prosecution
prosecution rebuttal character in a criminal case
if the D has opened the door by calling character witnesses the prosecution may rebut:
- by cross examining D’s character witnesses with “have you heard” or did you know? questions about specific acts of the D that reflect adversely on the particular character trait that the D has introduced to impeach the character witness’s knowledge and or
- by calling its own reputation or opinion witness to contradict the D’s witness
the prosecution must have a good faith basis for the questions it asks
Victim’s character-Self defense
the criminal D may introduce evidence of a victims violent character to prove the victim’s conduct in conformity
proper method: character witness may testify to vicitms reputation for violence and may give opinion
prosecution rebuttal: evidence of victims good character with reputation or opinion in FRE may prove the D’s character for violence but in OHIO rebuttal is limited to evidence of the victims good character
homicide: if the D offers evidence of any kind that the victim was the first aggressor, prosecution may introduce evidence of victims good character for peacefulness
if the D at the time of the alleged self defense was aware of the victims violent reputation or prior specific acts such awareness may prove the D’s state of mind as fear which would help to prove that he acted reasonably
victims character: sexual misconduct case
under the rape shield law, evidence about the victim is ordinarily inadmissible:
1. opinion or reputation evidence about the victims sexual propensity or
2. evidence of specific sexual behaviors of the victim
exceptions in criminal cases
1. specific acts of sexual behavior of the victim to prove that someone other than the D was the source of semen of injury
2. victims sexual activity with the D if the defense of consent is asserted OR
3. where the exclusion would violate the D’s right of due process (love triangle defense to suggest that the victim has motive to falsify the claim of rape)
exceptions in civil cases:
the court may admit evidence of specific sexual behavior or sexual propensity of the victim if it is probative value substantially outweighs the danger of harm to the victim and unfair prejudice to any party
character evidence in civil cases
- character evidence generally inadmissible to prove a persons conduct on a particular occasion
- evidence of a persons character is admissible where such character is an essential element of a claim or defense (provable by reputation, opinion, and specific acts) but only in 3 situations
- tort action alleging negligence hiring or entrustment
- defamation
- child custody dispute
defendants other crimes for non character purposes
Generally: other crimes or bad acts are not admissible during the prosecution's case in chief if the only purpose is to suggest that because of D's bad character he is more likely to have committed the crime currently charged BUT defendants bas acts or other crimes may be admissible to show something specific about a charged crime such as MIMIC Motive Intent Mistake, absence of Identity Common plan of scheme
method of proof of MIMIC purpose crimes
- by conviction or
- by evidence that proves the crime occurred: conditional relevancy standard, the prosecution only need produce sufficient evidence from which a reasonable juror could conclude that the D committed the other crime
upon the D’s request prosecution must give pretrial notice of intent to introduce mimic evidence OHIO does not expressly require pretrial notice but the court indicates that the practice is preferred
MIMIC in civil cases: if relevant to a non character purpose MIMic evidence can be used in civil cases
other sexual misconduct to show propensity in Sex-crime prosecution or civil action
FRE: in a case alleging sexual assault or child molestation, prior spcific sexual misconduct of the D is admissible as part of the case in chief (civil or criminal) for any relevant purpose including the D’s propensity for sex crimes ONLY prior specific acts
Ohio: allows for evidence of the D’s prior crimes involving sexual misconduct only if the MIMC rule is satisfied or the prior sexual acts were directed toward the vicitm in the pending case
authentication of writings: methods
- witness’s personal knowledge
- proof of handwriting by lay opinion, expert comparison or jury comparison
- proof by circumstantial evidence
- ancient document rule: authenticity is inferred if the document is at least 20 years old, facially free of suspicion, found in a place of natural custody
- solicited reply doctrine:can be authenticated if it was received in response to a prior communication to the alleged author
self authenticating documents
burden of proof on the opponent to show lack of authenticity:
- official publication (anything by the gov.)
- certified copies of public or private records on file in a public office (deed, mortgage)
- newspapers or periodicals
- trade inscriptions and labels
- acknowledged document (certified by notary public)
- commercial paper (promissory note, signature presumed genuine)
authentification of photo
witness may testify on the basis of personal knowledge that the photo is a fair and accurate representation of the people or objects portrayed
Best evidence rule
a party who seeks to prove the contents of a writing must either produce the original writing or provide an acceptable excuse for its absence
if the court finds that the excuse is acceptable, the party may use secondary evidence such as oral testimony or a copy
this rule generally applies in 2 situations:
1. the writing is legally operative document in the present case and creates the rights and obligations at issue
2. witness is testifying to facts that she learned solely from reading about them in a writing
what qualifies as an original writing?
- whatever the parties intended as the original, any counterpart intended to have the same effect and any negative of film or print from the negative, computer print out
- duplicate: any counterpart produces by any mechanical means that accurately reproduced the original Rule on duplicates: admissible to the same extent as the original UNLESS it would be unfair or a genuine question is raised as to authenticity of the original
- handwritten copy is neither an original or a duplicate
excuses for non production of an original
- lost or cannot be found with due diligence
- destroyed without bad faith (flood, fire theft)
- cannot be obtained with legal process (outside of the cts supeona power)
the court must be persuaded by a preponderance of the evidence that excuse has been established, and secondary evidence is admissible
escapes in best evidence rule
- voluminous records can be presented through a summary or chart provided the original records would be admissible and they are available for inspection
- certified copies of public records
- collateral documents not important to the merits of the care
witness competency
testimonial qualifications
basics:
1. personal knowledge (saw something with own eyes, heard it with own ears)
2. oath or affirmation (demonstrate willingness to tell the truth)
Ohio: court must disqualify a witness who is of unsound mind or a child under 10 if such child appears incapable of perceiving or accurately relating the facts. proponent must demonstrate that the child can give and appreciate an oath
dead man statute
- witness is not ordinarily incompetent merely becuase she has an interest in the outcome of the litigation
- BUT some states have a dead man’s statute which provides in a civil case, an interest witness is incompetent to testify in support of her own interest against the estate of the decedent concerning communications or transactions between the interested witness and the decedent
Ohio has abolished the dead man statute
ohio dead man statute
abolished but to keep an evidentiary balance there is a unique hearsay exception which allows the decedent to speak from the grave
After an interested witness has testified against a decedent’s estate, the estate may introduce pre-death statements of the decdent if:
- statements concern same subkect matter
- Statements rebut interested witness testimony and
- decdent had personal knowledge of the subject matter
leading questions
form of question suggest the answer generally not allowed on direct examination generally allowed on Cross BUT can be allowed on direct if: 1. for preliminary introductory matters 2. youthful or forgetful witness 3. hostile witness 4. witness is opposing party or under the control of the opposing party
refreshing recollection
basic: witnesses may not read from prepared memorandum, must testify on the basis of current recollection BUT if the memory fails him, he can be shown a memo or any other tangible item to jog his memory
safeguards: the adversary has the right to
1. inspect the memory refresher
2. to use it on cross
3. to introduce it into evidence
past recollection recorded
foundation for reading the contents of the writing into evidence
- showing the writing to the witness fails to jog the memory
- witness had personal knowledge at a former time
- writing was either made by witness or adopted by the witness
- making or adopting occurred while the event was still fresh in the wtiness’s memory
- witness can vouch for the accuracy of the writing when made or adopted
opinion testimony: Lay witness
admissible if: 1. rationally based on witness's perception and 2. helpful to the jury in deciding a fact (judges discretion) examples: drunk/sober speed of vehicle sane/insane emotions of another person odors handwriting character
expert witness
qualification: education and or experience
proper subject matter: scientific, technical, or other specialized knowledge that will be helpful to the jury in deciding the fact
basis of opinion:
must be based on a reasonable degree of probability or reasonable certainty
can draw upon
1. personal knowledge
2. other evidence in the trial record made known to the expert by hypothetical question
3. facts outside the record (hearsay) if of a type reasonably relied on by experts in the field when forming opinions
Ohio: must be based exclusively on personal knowledge of facts and data that have been introduced into evidence
expert testimony relevance and reliability
must be relevant to the issue at hand and sufficiently reliable
the court serves as the gatekeeper and will use four principal factors to determine the reliabilty of principles and methodology used by the expert (TRAP)
Testing of principles and methodology
Rate of error
Acceptance by other experts in the same discipline
Peer review and publication
learned treatise in the aid of expert testimony
- on direct: relevant portions of treatise, periodical or pamphlet may be read into evidence as substantive evidence if est as a reliable authority
- on cross: read into evidence to impeach and contradict opponents expert
- BUR may not be introduced as an exhibit
ultimate issues and testimony
opinion testimony is objectionable just becuase it embraces an ultimate issue in the case but all other requirements for opinions testimony must be satisfied including that the opinion is helpful
