509 U.S. 579 (1993)
The landmark case of Daubert v. Merrell Dow Pharmaceuticals, Inc.
Does the Frye 'general acceptance' test define the admissibility of expert scientific testimony in federal trials, or should a different standard be applied under the Federal Rules of Evidence?
Under the Federal Rules of Evidence, especially Rule 702, expert testimony must be based on scientifically valid reasoning or methodology that is relevant to the facts at issue, regardless of general acceptance in the particular field.
The Supreme Court held that the Frye standard was superseded by the Federal Rules of Evidence, which require that trial judges assess the scientific validity and relevance of expert testimony. Judges are to serve as gatekeepers under Rule 702, ensuring both the reliability and relevance of expert testimony.
Daubert fundamentally changed the judicial approach to evidence by broadening the admissibility criteria under the Federal Rules, enhancing the trial judge's role as a gatekeeper. The decision has wide-reaching implications, providing a more nuanced framework for handling scientific evidence. Law students must understand this case to comprehend the evolving nature of evidentiary standards and the implications for federal litigation.
