Utah Court of Appeals
Can Utah courts exclude expert testimony lacking factual support? Taylor v. University of Utah Explained
Summary
The Taylors sued medical providers alleging their daughter suffered permanent encephalopathy from baclofen withdrawal during pump replacement surgery. The district court excluded their causation expert’s testimony, finding it lacked sufficient factual basis under Rule 702.
Analysis
In Taylor v. University of Utah, the Utah Court of Appeals addressed when district courts may exclude expert testimony under Rule 702 of the Utah Rules of Evidence for lacking sufficient factual support.
Background and Facts
The Taylors’ daughter received intrathecal baclofen treatment for a neurological disorder through a pump and catheter system. After pump replacement surgery in 2013, the patient experienced increased spasticity suggesting baclofen withdrawal. Despite diagnostic testing showing no obvious problems, physicians replaced both the pump and catheter the next day. Weeks later, the patient developed psychotic behavior that the Taylors attributed to permanent encephalopathy caused by baclofen withdrawal during the brief period before pump replacement.
Key Legal Issues
The central issue was whether the Taylors’ causation expert’s testimony satisfied Rule 702’s threshold showing of reliability. The expert proposed to testify that baclofen withdrawal caused metabolic disturbance leading to permanent encephalopathy, but conceded she had never seen such permanent injury in her practice and could find no supporting medical literature.
Court’s Analysis and Holding
The Court of Appeals affirmed the district court’s exclusion of the expert testimony. Under Rule 702, expert opinions must be based on sufficient facts or data. Here, the expert’s logical deduction methodology lacked adequate factual support. The expert admitted no patients in her experience suffered permanent injury from baclofen withdrawal, and medical literature indicated withdrawal symptoms typically resolve within 48 hours of baclofen reinstatement. Without exposure to a nearly identical situation or supporting literature, the expert’s causation opinion failed Rule 702’s reliability requirements.
Practice Implications
This decision reinforces that expert testimony cannot rely solely on theoretical reasoning without factual grounding. Medical malpractice practitioners must ensure causation experts can demonstrate either relevant personal experience or published support for their opinions. The court’s gatekeeper role under Rule 702 requires rational skepticism toward expert testimony lacking adequate factual foundation.
