In Freeman v. Fon’s Pest Management, Inc., the Louisiana Supreme Court found that the lower courts erred in granting the defendant’s motions in limine and striking the expert testimony of four of the plaintiff’s experts. The lawsuit alleged that the defendant used a pesticide which contained a chemical called fipronil to treat plaintiffs’ home for termites. Following the treatment, plaintiffs began to suffer headaches, nausea, dizziness, and confusion. To prove causation, plaintiffs retained four different experts – three toxicologists and one Certified Industrial Hygienist. In response, the defendant pest management company filed pre-trial motions to exclude the testimony of plaintiffs’ experts, claiming their testimony did not meet the standard for admissibility under Louisiana Code of Evidence article 702 and Daubert v. Merrell Dow Pharmaceuticals, Inc.
The district court granted the defendant’s motions in limine, striking plaintiff’s experts because it found: 1) none of the proposed experts had expertise regarding fipronil; 2) none of the four experts had written or contributed to any peer-reviewed articles regarding the effects of fipronil (or any pesticides) in humans; 3) none of the four experts attempted a dose reconstruction to determine the amount of exposure to fipronil allegedly suffered by the plaintiffs; 4) none of the experts reviewed any biological or air quality data to establish the plaintiffs were exposed to fipronil; and 5) no articles or studies reviewed by the experts proved any causal connection between fipronil and the plaintiff’s claimed injuries. In addition, the testimony of all four experts conflicted on the effects of fipronil exposure.
The court of appeal affirmed.
