Witness Issues Flashcards
Competency of Witnesses - 2 Requirements
- Personal Knowledge
2. Oath or affirmation
Dead Man’s Statute
Generally, witness is not ordinarily incompetent merely because she has an interest (direct legal stake) in the outcome of the litigation.
BUT some states have “dead man statutes” that provide in a CIVIL action, an interested witness is incompetent to testify in support of her own interest against the estate concerning communications or transaction between the interested witness and the decedent.
Leading Questions
Generally ARE allowed on cross; generally NOT allowed on direct.
BUT 4 exceptions where leading questions are allowed on direct:
- preliminary/introductory matters
- Youthful or forgetful witness
- hostile witness
- adverse party/someone under control of adverse party
Refreshing Recollection
Generally, a witness may not read from prepared script, and must testify on basis of current recollection.
HOWEVER, if witness’s memory fails, he may be shown a memo or other tangible item to jog his memory.
The writing itself is NOT part of evidence, and after looking at it witness must then testify from present recollection.
ADVERSARY has the right to:
- inspect the memory-refresher
- use it on cross examination
- introduce it into evidence
Past Recollection Recorded (a HEARSAY exception)
May read contents of writing into evidence if meet foundation:
- showing the writing to witness fails to jog his memory
- the witness HAD personal knowledge at a former time
- writing was either MADE or adopted by the witness
- making/adoption occurred while the event was fresh in witness’s memory
- witness can vouch for accuracy of writing when made
proponent STILL CANNOT introduce the writing itself into evidence. But OPPONENT may.
When is Lay OPINION testimony admissible?
- the opinion is rationally based on the witness’s perception and
- the opinion is HELPFUL to the jury
Expert Witness Opinion Testimony - Qualification?
based on education and/or experience
Expert Witness Opinion Testimony - Proper Subject Matter?
Specialized knowledge that will be HELPFUL to the jury in deciding a fact.
Expert Witness Testimony - permissible Bases of Opinion?
must be based on “reasonable degree of PROBABILITY or REASONABLE CERTAINTY.”
May base opinion on any of 3 sources:
- Personal knowledge (e.g. treating doctor)
- other evidence admitted at trial made known to the expert by HYPOTHETICAL questions
- Facts OUTSIDE the record IF they are of the type reasonably relied on by experts in the particular field in forming opinions. (but CONTENTS of such out of court material should not be disclosed unless judge decides it would help them evaluate expert’s opinion)
Expert Witness Testimony - Relevance/Level of Reliability Required?
must be relevant (duh) and SUFFICIENTLY RELIABLE (1. reliable methods and principles AND 2. reliably applies those methods/principles to the facts)
4 reliability factors
- Testing of principles and methods
- Rate of error of the principles and methods used
- Acceptance of the methods by other experts in the same discipline.
- Peer review or publication of the methods/principles
Expert Witness - use of learned treatise
On DIRECT of own expert, may read into evidence relevant portions of treatise, etc. as SUBSTANTIVE EVIDENCE, if it is established as a reliable authority.
On CROSS - may read treatise into evidence to impeach or contradict the opponent’s expert. Again, as substantive evidence.
May NOT introduce treatise as exhibit.
Expert Witness Testimony - Ultimate Issue?
Opinion testimony (lay or expert) is NOT objectionable merely because it embraces an “ultimate issue.” BUT will be considered NOT HELPFUL, and therefore not admissible if it’s mere regurgitation of legal standard. e.g. “In my opinion D’s conduct showed a reckless disregard for the safety of others.”
BUT in criminal cases expert may not give direct opinion that the defendant did or did not have relevant MENTAL state.
e.g. can’t say “D’s insanity prevented him from understanding wrongfulness of act.” Can say “D has mental illness. Person with this mental illness cannot understand fact from fantasy.”
Cross Examination - proper subject matter?
A party has a RIGHT to cross examine any opposing witness who testifies at the trial.
Proper subject matter:
- Matters WITHIN THE SCOPE of direct examination AND
- Matters that test witness’s credibility.
Credibility - Bolstering One’s Own Witness
Bolstering witness’s credibility is not allowed until after his credibility has been attacked (aka rehabilitation)
EXCEPT:
Prior Identification of a person - if a witness who previously identified a person testifies at trial and is subject to cross examination, Witness may not only presently identify person but also add that they previously identified the same person.
Impeachment Methods (7)
Prior Inconsistent statements
Bias, Interest or Motive to Misrepresent
Sensory Deficiencies
Bad Reputation/Opinion about character for truthfulness
Criminal Convictions
Bad Acts (without conviction) that reflect adversely on witness’s character for truthfulness
Contradiction
