Case Brief Summary & Legal Analysis
tl;dr: A court reversed the exclusion of expert testimony linking Bendectin to birth defects. It held that the expert’s novel reanalysis of existing data should be evaluated for reliability under FRE 702, not rejected under FRE 703 simply because it contradicted published conclusions.
Legal Significance: The case clarifies the distinct roles of FRE 703 (basis of testimony) and FRE 702 (reliability of methodology). It establishes that novel scientific methodologies, even those not generally accepted, are admissible if found reliable under a flexible standard, rejecting a rigid statistical significance requirement.

Case Facts & Court Holding
Key Facts & Case Background
The DeLucas sued Merrell Dow Pharmaceuticals, alleging the morning sickness drug Bendectin caused their daughter’s limb reduction birth defects. To prove causation, they relied solely on the expert testimony of Dr. Alan Done. Dr. Done reanalyzed data from numerous published epidemiological studies on Bendectin. While the authors of those studies had concluded there was no “statistically significant” link between Bendectin and birth defects (i.e., a p-value greater than .05), Dr. Done disagreed. Using a methodology that de-emphasized statistical significance in favor of analyzing relative risk and confidence intervals across multiple studies, he concluded that the collective data indicated Bendectin was a human teratogen. His analysis had not been peer-reviewed or published. Merrell Dow’s own experts relied on the same underlying epidemiological data to reach the opposite conclusion. The district court, finding Dr. Done’s opinion was not based on data reasonably relied upon by experts, excluded his testimony under Federal Rule of Evidence (FRE) 703 and granted summary judgment for Merrell Dow.
