Case Brief Summary & Legal Analysis

General Brief
4 min read

tl;dr: An appellate court vacated a jury verdict because the trial court admitted expert medical testimony based on a controversial scientific test without first determining if the test’s underlying data was reasonably relied upon by experts in the field, as required by the Federal Rules of Evidence.

Legal Significance: This case solidifies the trial court’s gatekeeping function under Federal Rule of Evidence 703, mandating a preliminary inquiry into the reliability of the underlying data for expert testimony before it can be admitted, rather than leaving the issue solely for the jury to weigh.

Case Facts & Court Holding

Key Facts & Case Background

Plaintiff Barbara Head sued Lithonia Corporation for products liability after a reflector from a light fixture fell and struck her on the head. To prove causation and the extent of her injury, post-concussive syndrome, Head offered the expert testimony of her treating neurologist, Dr. Haugh. While standard neurological tests like an EEG and CAT-scan were normal, Dr. Haugh based his diagnosis primarily on the results of a topographical brain mapping test. During a videotaped deposition, Dr. Haugh admitted that this technique was controversial within the neurological community and that he was unaware of any official position on it from the American Academy of Neurology. Lithonia objected to the admission of the test results and the expert opinion based upon them, arguing that the plaintiff had not established a proper foundation for the reliability of topographical brain mapping as required by Federal Rule of Evidence 703. The district court overruled the objection without explanation or conducting any inquiry into the test’s scientific reliability. The jury returned a verdict for the plaintiff.
