What happened in this matter?
Fabricated: Case Law | Defendants alleged numerous hallucinated (fabricated) citations appeared in El‑Ghannam's case‑specific report in this MDL; the court noted Bard had not identified any fully hallucinated citations in El‑Ghannam's General Report and found the AI challenge raised in reply untimely and insufficient to exclude the expert. Outcome: Challenge to the expert's report as AI-generated rejected (raised first in reply; mere suspicion is not enough); motion to exclude granted in part on other grounds (the expert may not opine on two causation points); no sanction. Defendants raised in reply that Dr. El‑Ghannam used ChatGPT and that his case‑specific report contained hallucinated (fabricated) citations, citing a different MDL filing where hallucinated sources were confirmed. The Court found the AI argument untimely, noted Bard had not identified any fully hallucinated citations in the General Report, and observed El‑Ghannam admitted limited ChatGPT use but testified he wrote and verified the report. The Court refused to exclude opinions on that basis and imposed no sanction.
