CFC Legal Standards & Expert Witness Testimony 5 — Questions and Answers
Question 1: An expert witness who holds a financial interest in the outcome of the case is most likely subject to:
- Automatic disqualification under all federal rules
- Impeachment for bias and potential exclusion if the interest is undisclosed (Correct answer)
- Criminal prosecution for perjury
- Increased compensation permitted under FRCP 26
Correct answer: Impeachment for bias and potential exclusion if the interest is undisclosed
A financial stake in the outcome constitutes bias that opposing counsel may use to impeach credibility; failure to disclose may also lead to sanctions or exclusion.
Question 2: Under the Confrontation Clause of the Sixth Amendment, a criminal defendant's right to confront expert witnesses means:
- All expert opinions must be delivered in writing and not orally
- The defendant has the right to cross-examine experts who testify against them (Correct answer)
- Defense experts must share their reports with prosecution before trial
- Laboratory analysts need not testify if their reports are certified
Correct answer: The defendant has the right to cross-examine experts who testify against them
The Confrontation Clause guarantees the right to cross-examine witnesses offering testimony against a criminal defendant, including expert witnesses.
Question 3: A forensic consultant is retained but later learns the same firm previously consulted for the opposing party in the same matter. This creates a:
- Waivable conflict that must be disclosed to both parties (Correct answer)
- Basis for automatic sanctions under FRCP 37
- Peer review obligation before testimony
- Permissible dual engagement with no disclosure required
Correct answer: Waivable conflict that must be disclosed to both parties
Prior engagement with the opposing party creates a conflict requiring disclosure; the conflict may be waivable if both parties provide informed consent.
Question 4: Which best describes the 'ultimate issue' rule as modified by FRE 704?
- Experts may never opine on the ultimate legal issue in a case
- Experts may opine on the ultimate issue except on mental state in criminal cases under FRE 704(b) (Correct answer)
- Experts must restrict opinions to technical facts, not legal conclusions
- The ultimate issue rule was eliminated entirely and experts may opine on all issues
Correct answer: Experts may opine on the ultimate issue except on mental state in criminal cases under FRE 704(b)
FRE 704 permits opinion on the ultimate issue generally, but FRE 704(b) prohibits experts from stating whether a criminal defendant did or did not have the requisite mental state.
Question 5: When preparing for deposition as an expert witness, which practice is most critical to maintain credibility?
- Memorizing the report verbatim to avoid any deviation
- Thoroughly reviewing all materials relied upon and being prepared to explain the methodology (Correct answer)
- Limiting answers to yes/no responses whenever possible
- Agreeing with opposing counsel's characterizations to appear cooperative
Correct answer: Thoroughly reviewing all materials relied upon and being prepared to explain the methodology
Credibility in deposition comes from thorough preparation, command of the underlying materials, and the ability to clearly explain one's methodology.
Question 6: Which scenario would most likely constitute improper ex parte communication by a court-appointed expert under FRE 706?
- Submitting a written report simultaneously to both parties and the court
- Privately meeting with one party's attorneys to discuss opinions before the hearing (Correct answer)
- Conducting independent research and documenting it in the report
- Testifying at trial and being cross-examined by both parties
Correct answer: Privately meeting with one party's attorneys to discuss opinions before the hearing
Court-appointed experts must maintain impartiality and may not engage in private, one-sided communications with a party, which would undermine the court's neutrality.
Question 7: A forensic expert's report contains a calculation error discovered after filing. Under professional standards, the expert should:
- Wait for opposing counsel to discover and raise the error during cross-examination
- Immediately notify retaining counsel, issue a corrected report, and disclose the correction (Correct answer)
- Withhold disclosure since the error may not affect the ultimate opinion
- Amend only the final conclusion without noting the underlying calculation change
Correct answer: Immediately notify retaining counsel, issue a corrected report, and disclose the correction
Professional integrity and candor to the tribunal require prompt disclosure of material errors and issuance of a corrected report.
