Q: What happens if a Daubert challenge is successful?

Definition & Meaning

A Daubert challenge is a legal proceeding where a judge evaluates the validity and admissibility of expert testimony. During this hearing, the opposing party questions the expert's methods and reasoning, requiring the expert to show that their approach is scientifically sound and applicable to the case at hand. This process stems from the 1993 U.S. Supreme Court case, Daubert v. Merrell Dow Pharmaceuticals, Inc., which established criteria for admitting scientific expert testimony.

Example 1: In a personal injury lawsuit, the defense may file a Daubert challenge against the plaintiff's medical expert, arguing that the expert's methods for determining causation are not scientifically accepted.

Example 2: A criminal case involving forensic evidence may see the prosecution facing a Daubert challenge regarding the reliability of DNA testing methods used to link the defendant to the crime scene.

Relevant laws & statutes

The primary legal reference for Daubert challenges is the U.S. Supreme Court decision in Daubert v. Merrell Dow Pharmaceuticals, Inc., 509 U.S. 579 (1993). This ruling established the standard for admissibility of expert testimony in federal courts. The subsequent case of Kumho Tire v. Carmichael, 526 U.S. 137 (1999), extended these principles to non-scientific expert testimony.
