Witness Competency, Personal Knowledge, and Examination

Key Takeaways Explain This Topic AI

FRE 601: every person is presumed competent to testify; FRE 602: a witness may testify only to matters of which she has PERSONAL KNOWLEDGE (proved by the witness's own testimony); FRE 603: witnesses must take an oath or affirmation.

FRE 605 bars the presiding judge from testifying; FRE 606 bars a juror from testifying before the empaneled jury and limits juror testimony to impeach a verdict (extraneous prejudicial information, outside influence, or clerical mistake — NOT mental processes; Pena-Rodriguez carves out racial bias).

FRE 611: the court controls the mode and order of examination; LEADING questions are generally improper on direct but allowed on cross, with hostile/adverse/identifying witnesses, and for preliminary matters.

FRE 612 (refreshing recollection): a witness may review any writing to refresh memory and then testifies from memory; the adverse party may inspect it and introduce relevant portions — distinguish from the FRE 803(5) recorded-recollection hearsay exception.

California: CEC 700-701 (competency — disqualified only if incapable of expressing oneself understandably or of understanding the duty to tell the truth); CEC 702 (personal knowledge); the abolished Dead Man's Statute is replaced by CEC 1261 hearsay treatment of a decedent's statements.

FRE 601 abolishes most common-law disqualifications: every person is competent to be a witness unless the rules provide otherwise (in federal diversity cases, state competency law governs an element or defense as to which state law supplies the rule of decision). Children and the mentally impaired are not categorically barred; the trier weighs their credibility. FRE 602 supplies the real gatekeeper: a witness may testify only if evidence is introduced sufficient to support a finding that she has PERSONAL KNOWLEDGE of the matter — and that proof may consist of the witness's own testimony.

Personal knowledge means perception through the senses; a witness who merely heard a rumor lacks it. FRE 603 requires an oath or affirmation to testify truthfully, in a form designed to impress that duty on the witness's conscience; no particular religious formula is required.

FRE 605 flatly prohibits the presiding judge from testifying as a witness at the trial; no objection is needed to preserve the issue. FRE 606(a) likewise bars a sitting juror from testifying before the other jurors. FRE 606(b) is heavily tested: when validity of a verdict or indictment is challenged, a juror may NOT testify about any statement made or incident that occurred during deliberations, the effect of anything on a juror's vote, or any juror's mental processes.

Three exceptions permit juror testimony: (1) extraneous prejudicial information was improperly brought to the jury's attention (a juror's independent internet research), (2) an outside influence was improperly brought to bear (a bribe or threat), or (3) a mistake was made entering the verdict on the form. Pena-Rodriguez v. Colorado (2017) adds a constitutional exception: a juror's statement showing reliance on RACIAL stereotypes or animus may be received to protect the Sixth Amendment right. Note that a juror's misunderstanding of instructions or intoxication is NOT a basis to impeach the verdict (Tanner v. United States).

FRE 611(a) gives the court reasonable control over the mode and order of examining witnesses and presenting evidence to make procedures effective, avoid wasting time, and protect witnesses. FRE 611(b) limits cross-examination to the subject matter of the direct and matters affecting credibility (the court may allow more). FRE 611(c) governs LEADING questions — those suggesting the answer. They are ordinarily improper on direct examination but PERMITTED on cross, on direct of a hostile witness or an adverse party (or a witness identified with an adverse party), and to develop preliminary or undisputed matters.

FRE 612 allows refreshing a witness's present recollection with ANY item (a writing, a photo, an object — it need not be admissible or even authored by the witness). The witness reviews it, sets it aside, and testifies FROM REFRESHED MEMORY; the item itself is not evidence. The adverse party is entitled to inspect it, cross-examine on it, and introduce relevant portions. Do not confuse this with FRE 803(5) past recollection recorded, where the witness's memory is NOT revived and a qualifying record is read into evidence (but not admitted as an exhibit by the offering party).

Several additional examination rules round out witness handling. FRE 615 (the 'rule on witnesses' or sequestration) requires the court, on a party's request, to order witnesses excluded so they cannot hear other testimony — but it carves out four categories that may remain: a party who is a natural person; an officer or employee designated as a party's representative (the corporate designee); a person whose presence is shown to be essential to presenting the party's claim or defense (an expert who must hear the testimony); and a person whose presence is authorized by statute, such as a crime victim.

The 2023 amendment clarifies that the order also bars excluded witnesses from being told about trial testimony and from accessing transcripts while excluded. FRE 604 requires an interpreter to be qualified and to take an oath to make a true translation, and a third party whose presence is necessary to facilitate privileged legal advice — including an interpreter — does not destroy the attorney-client privilege.

On cross-examination, FRE 611(b) confines questioning to the subject matter of the direct examination and to matters affecting the witness's credibility, though the court has discretion to permit inquiry into additional matters as if on direct; this 'restrictive' American rule contrasts with the 'wide-open' approach some states follow. Two recurring traps deserve emphasis.

First, refreshing recollection under FRE 612 must use a writing only to JOG memory; if counsel effectively reads the document to the witness who then parrots it, the court may treat the testimony as an improper backdoor for an unadmitted document, and the adverse party gains the right to inspect, cross-examine on, and introduce relevant portions of whatever was used.

Second, the no-impeachment rule of FRE 606(b) is narrow: jurors may testify to extraneous information, outside influence, or a clerical error in entering the verdict, and Pena-Rodriguez adds racial bias, but Tanner v. United States holds that juror drug or alcohol use, fatigue, and ordinary misunderstanding of instructions are internal matters that cannot impeach the verdict.

California parallels much of this: CEC 777 authorizes witness exclusion, CEC 765 directs the court to control interrogation to protect witnesses (with special solicitude for child witnesses under CEC 765(b)), and CEC 1150 limits impeachment of a verdict to objectively ascertainable overt acts or events, excluding evidence of the jurors' subjective mental processes — a limitation comparable to FRE 606(b) but framed around 'overt' conduct.

Refreshing Recollection (612) vs. Recorded Recollection (803(5))

Feature Refreshing (FRE 612) Recorded Recollection (FRE 803(5))
Memory revived? Yes — witness now remembers No — memory not revived
What is evidence? The witness's live testimony The contents of the record (read aloud)
Foundation Anything that jogs memory Witness once had knowledge; record made/adopted when fresh; accurate
Who may admit as exhibit Item is not evidence Adverse party may admit; proponent only reads it
Authentication of the item Not required Must show accuracy

California competency is governed by CEC 700-704. CEC 700 presumes every person competent. CEC 701 disqualifies a witness ONLY if she is (a) incapable of expressing herself so as to be understood (directly or through interpretation) or (b) incapable of understanding the duty to tell the truth. CEC 702 requires personal knowledge; CEC 710 requires the oath or affirmation.

Importantly, California has NO Dead Man's Statute that disqualifies an interested survivor from testifying about transactions with a decedent — instead, CEC 1261 admits a decedent's hearsay statements in an action against the estate (offered in good faith, on the declarant's personal knowledge), so the protection runs through hearsay rather than competency. On a CA essay, never disqualify a survivor witness on Dead Man grounds; analyze CEC 1261 hearsay instead.
