The Supreme Court’s celebrated 1993 decision in Daubert v. Merrell Dow Pharmaceuticals, Inc. adopted a new empirical validation test for the admissibility of scientific evidence. In criminal cases, defense counsel started challenging the prosecution’s forensic evidence identifying the accused as the perpetrator. In civil tort cases, defense counsel filed motions attacking the plaintiff’s evidence on general causation. When counsel won these motions, the opposition lacked sufficient evidence to go to trial. The hearing on the pretrial Daubert motion became the centerpiece of the litigation. This symposium was presented in two parts. In the first segment, a federal judge and two experienced attorneys conducted a Daubert hearing on a controversial type of expert testimony. During the second segment, our expert academic panel commented on scientific evidence and discussed the law, strategy, and tactics of Daubert hearings.
