Witness Competency Flashcards
Threshold requirements for a witness to testify at trial
A witness must have personal knowledge of an issue in the case, be competent to testify, and be willing to take an oath or make an affirmation
These are merely threshold requirements; the witness testimony must also be relevant and otherwise admissible under the rules.
Rule 601 - Competency to Testify in General
Every person is competent to be a witness unless these rules provide otherwise. But in a civil case, state laws governs the witness’s competency regarding a claim or defense for which state law supplies the rule of decision.
Rule 602 - Need for Personal Knowledge
A witness may testify to a matter only if evidence is introduced sufficient to support a finding that the witness has personal knowledge of the matter. Evidence to prove personal knowledge may consist of the witness’s own testimony. This rule does not apply to a witness’s expert testimony under Rule 703.
Two broad categories of witnesses
(1) percipient (or fact) witnesses – a witness who has seen, heard, touched, felt, otherwise perceived with her senses, or has personal experience with, a factual matter relevant to the case.
(2) opinion witnesses – one who shares her opinion with the jury. Further divided into two categories: lay opinion witnesses and expert witnesses.
Personal knowledge requirement and conditional relevance
The requirement of personal knowledge under Rule 602 is an issue of conditional relevancy under Rule 104. The judge does not find that the witness has personal knowledge, but rather that a reasonable juror could find that the witness has personal knowledge
Generally satisfied with foundational question like “Did you see a car accident on July 5?”
Rule 603 - Oath or Affirmation to Testify Truthfully
Before testifying, a witness must give an oath or affirmation to testify truthfully. It must be in a form designed to impress that duty on the witness’s conscience.
Rule 605 - Judge’s Competency as a Witness
The presiding judge may not testify as a witness at the trial. A party need not object to preserve the issue.
Rule 606(a) - Juror’s Competency as a Witness - At the Trial
At the Trial. A juror may not testify as a witness before the other jurors at the trial. If a juror is called to testify, the court must give a party an opportunity to object outside the jury’s presence.
Rule 606(b) - Juror’s Competency as a Witness - During an Inquiry into the Validity of a Verdict or Indictment
(1) Prohibited Testimony or Other Evidence. During an inquiry into the validity of a verdict or indictment, a juror may not testify about any statement made or indictment that occurred during the jury’s deliberations; the effect of anything on that juror’s or another juror’s vote; or any juror’s mental processes concerning the verdict or indictment. The court may not receive a juror’s affidavit or evidence of a juror’s statement on these matters.
(2) Exceptions. A juror may testify about whether:
(A) extraneous prejudicial information was improperly brought to the jury’s attention;
(B) an outside influence was improperly brought to bear on any juror; or
(C) a mistake was made in entering the verdict on the verdict form
Rule 612(a) - Writing Used to Refresh a Witness’s Memory - Scope
Scope. This rule gives an adverse party certain options when a witness uses a writing to refresh memory:
(1) while testifying; or
(2) before testifying, if the court decides that justice requires the party to have those options.
Rule 612(b) - Writing Used to Refresh a Witness’s Memory - Adverse Party’s Options: Deleting Unrelated Matter
(b) Adverse Party’s Options: Deleting Unrelated Matter. Unless 18 U.S.C. § 3500 provides otherwise in a criminal case, an adverse party is entitled to have the writing produced at the hearing, to inspect it, to cross-examine the witness about it, and to introduce in evidence any portion that relates to the witness’s testimony. If the producing party claims that the writing includes unrelated matter, the court must examine the writing in camera, delete any unrelated portion, and order that the rest be delivered to the adverse party. Any portion deleted over objection must be preserved for the record.
Rule 612(c) - Writing Used to Refresh a Witness’s Memory - Failure to Produce or Deliver the Writing
o (c) Failure to Produce or Deliver the Writing. If a writing is not produced or is not delivered as ordered, the court may issue an appropriate order. But if the prosecution does not comply in a criminal case, the court must strike the witness’s testimony or—if justice so requires—declare a mistrial.
Two methods for refreshing
Leading question to prod the witness’s memory, or
Using the formal foundation for refreshing recollection
Steps for using the gently leading question in witness refreshing
- The witness mistakes a non-material fact on direct examination
- Noticing that the witness has done so, the attorney quickly corrects the witness with a leading question.
- If the attorney draws an objection, the attorney rephrases the question as a non-leading question and gives the witness the opportunity to try again.
The formal foundation for refreshing recollection
- The witness forgets an important fact
- The attorney rephrases the question in order to clarify that the witness has in fact forgotten.
- The attorney asks if anything will refresh the witness’s recollection.
- The witness says yes.
- The attorney marks the document or item as an exhibit for identification, shows it to opposing counsel, and then gives it to the witness. [Note, in some cases, having established that the witness has forgotten something, the attorney might skip steps 3 and 4 and go directly to step 5.]
- After the witness has finished examining the item or document, the attorney retrieves it from the witness and asks whether it has refreshed the witness’s recollection.
- If the witness replies affirmatively, the attorney re-asks the question from before
- The witness replies from memory
