CFE Legal and Ethical Considerations in Forensics 3 — Questions and Answers
Question 1: A forensic examiner testifies that they are 'absolutely certain' of their conclusion. From an ethical standpoint, this statement is problematic because:
- It may sound too confident to a jury
- Forensic science rarely supports absolute certainty, and overstating conclusions is misleading (Correct answer)
- It violates attorney-client privilege
- Certainty is reserved only for DNA evidence
Correct answer: Forensic science rarely supports absolute certainty, and overstating conclusions is misleading
Ethical forensic testimony requires expressing conclusions with appropriate uncertainty; claiming absolute certainty overstates the science and can mislead the trier of fact.
Question 2: The concept of 'confirmation bias' in forensic examinations refers to:
- The tendency to seek or interpret evidence in a way that confirms pre-existing beliefs (Correct answer)
- A method of verifying digital signatures
- A legal standard for corroborating witness testimony
- The process of confirming chain of custody documentation
Correct answer: The tendency to seek or interpret evidence in a way that confirms pre-existing beliefs
Confirmation bias leads examiners to unconsciously favor evidence that supports a hypothesis they already hold, threatening objectivity and accuracy.
Question 3: Under the work-product doctrine, which of the following materials is typically protected from disclosure to opposing counsel?
- The forensic examiner's final report submitted to the court
- An attorney's mental impressions and legal strategies contained in notes (Correct answer)
- Physical evidence collected at a crime scene
- Publicly available scientific literature cited by the expert
Correct answer: An attorney's mental impressions and legal strategies contained in notes
The work-product doctrine protects an attorney's mental impressions, conclusions, and legal strategies prepared in anticipation of litigation.
Question 4: A forensic examiner who simultaneously serves as a consultant for the prosecution and receives payment from the defense in the same case faces what ethical issue?
- Fee splitting
- Conflict of interest (Correct answer)
- Unauthorized practice of law
- Breach of confidentiality
Correct answer: Conflict of interest
Serving opposing parties in the same case creates a direct conflict of interest that undermines the examiner's objectivity and violates professional ethics codes.
Question 5: Which of the following best describes the ethical obligation of a forensic examiner when they realize a mistake in a previously submitted report?
- Wait until cross-examination to reveal the error
- Immediately notify the retaining party and issue a corrected report (Correct answer)
- Only correct the error if it would change the ultimate conclusion
- Amend the report without notifying anyone
Correct answer: Immediately notify the retaining party and issue a corrected report
Examiners have an affirmative duty to promptly disclose and correct errors in submitted reports to ensure accuracy and maintain integrity.
Question 6: In federal criminal cases, Rule 16 of the Federal Rules of Criminal Procedure requires that expert witness disclosures include:
- The expert's financial compensation arrangement only
- A written summary of the opinion, the bases for it, and the expert's qualifications (Correct answer)
- Only the expert's CV and contact information
- The full case notes but not the methodology
Correct answer: A written summary of the opinion, the bases for it, and the expert's qualifications
Rule 16 mandates disclosure of a written summary covering the expert's opinions, the basis and reasons for those opinions, and the expert's qualifications.
Question 7: When a forensic examiner's findings would exonerate a defendant but the retaining prosecutor does not want those findings disclosed, the examiner's ethical duty is to:
- Suppress the findings at the prosecutor's direction
- Disclose the exculpatory findings, as Brady obligations require the prosecution to share them (Correct answer)
- Destroy the exculpatory evidence to protect the case
- Remain silent and let the attorneys resolve it
Correct answer: Disclose the exculpatory findings, as Brady obligations require the prosecution to share them
Brady v. Maryland requires prosecutors to disclose exculpatory evidence; a forensic examiner must report all findings and cannot participate in suppressing them.
