Kent Higgins inhaled chlorine gas at the Holiday World Amusement Park when the ride he was on malfunctioned. Higgins suffered chronic asthma and reactive airways dysfunction syndrome, or RADS, as a result of the alleged negligence of the defendant, Koch Development, the owner of Holiday World Amusement Park.
Higgins, the plaintiff, hired a causation expert physician, but the doctor was barred. The issue was whether this expert could be substituted with his treating pulmonologist to act as his expert under the guidelines of Daubert v. Merrell Dow Pharmaceuticals, Inc., 509 U.S. 579 (1993).
The trial judge barred Higgins’s causation expert. He then offered up his treating pulmonologist to act as his expert on causation. The district court judge found that the treating physician was unqualified to opine on the effect chlorine gas has on the human pulmonary system. The basis of the barring was under the Daubert criteria and methodology, which was found to be too uncertain to determine its reliability.
