Case Brief Summary & Legal Analysis
tl;dr: A trial court excluded plaintiffs’ expert witness for alleged bias. The appellate court reversed, holding that an expert’s potential bias affects the weight of their testimony for the jury to decide, not its admissibility under the Daubert standard for expert evidence.
Legal Significance: This case reinforces that a trial court’s Daubert gatekeeping function is limited to assessing an expert’s qualifications and methodological reliability, not their credibility or potential bias, which are issues of weight reserved for the jury.

Case Facts & Court Holding
Key Facts & Case Background
In a medical malpractice and EMTALA action, the plaintiffs’ case relied on a single expert witness, Dr. Carlos E. Ramírez. Dr. Ramírez was an OB/GYN with 26 years of faculty experience, though his board certification had expired and he had ceased clinical practice after a cancer diagnosis. In recent years, he served as a consultant and expert witness in approximately 150 cases, primarily for plaintiffs, and co-lectured on medical malpractice with the plaintiffs’ attorney. During a mid-trial Daubert hearing, the defendants moved to exclude his testimony. The district court granted the motion, not because Dr. Ramírez lacked qualifications or because his methodology was scientifically unsound, but on the grounds that he was biased. The court reasoned that his work almost exclusively for plaintiffs, his for-profit lectures, and his withdrawal from clinical practice indicated he was not an impartial witness but rather a “hired gun.” Because the plaintiffs had no other expert to establish the standard of care or causation, the court granted judgment as a matter of law for the defendants.
