The Daubert Standard is a rule of evidence regarding the admissibility of expert witness testimony, requiring that such testimony be both relevant and reliable.

The Daubert Standard was established by the U.S. Supreme Court in Daubert v. Merrell Dow Pharmaceuticals, Inc. (1993) to provide a framework for evaluating the reliability of expert testimony in federal courts. It shifted the focus from the earlier Frye standard, which merely required that expert techniques be generally accepted in the scientific community, and instead mandated a more rigorous examination of the reasoning and methodology underlying the testimony. Courts are now tasked with evaluating whether the expert's methods are scientifically valid and applicable to the facts of the case at hand.
Under the Daubert framework, judges act as 'gatekeepers' to ensure that any and all scientific testimony or evidence admitted is not only relevant but also reliable. In assessing reliability, courts are encouraged to consider several factors, including whether the theory or technique has been tested, whether it has been subjected to peer review and publication, the known or potential error rate, and the general acceptance within the scientific community.
The application of the Daubert Standard has broad implications for litigation, particularly in cases involving complex scientific and technical evidence. Judges are afforded considerable discretion in their gatekeeping role, which means outcomes can vary based on the specific facts, the expert's qualifications, and the court's interpretation of reliability. This discretion has led to a significant amount of litigation about the admissibility of expert testimony.
The Daubert Standard also places a heavier burden on parties seeking to introduce expert testimony, as they must demonstrate that their expert's methods and conclusions are not only scientifically valid but also relevant to the specific issues in the case. This requirement can greatly influence the strategies of attorneys in preparing their cases and selecting expert witnesses.
The Daubert Standard was developed in 1993 with the U.S. Supreme Court's decision in Daubert v. Merrell Dow Pharmaceuticals, which addressed the admissibility of expert scientific evidence in federal courts.
Established the Daubert Standard for evaluating the admissibility of expert testimony.
Clarified that the abuse of discretion standard applies when appellate courts review a trial court's Daubert ruling.
Extended the Daubert Standard to all types of expert testimony, not just scientific.
Illustrated the application of the Daubert Standard in the context of social science expert testimony.
Reaffirmed the trial court's role as a gatekeeper in assessing expert testimony under Daubert.
In a product liability case involving a medical device, the plaintiff presents an expert witness who claims the device is unsafe based on unpublished studies. The defense moves to exclude this testimony, arguing that the expert's methodology has not been peer-reviewed, failing the reliability standard established by Daubert.
Confusion: Students often think Daubert only applies to scientific evidence.
Clarification: In fact, Daubert applies to all forms of expert testimony, including technical and specialized knowledge.
Confusion: Some believe Daubert only focuses on the expert's qualifications.
Clarification: Daubert emphasizes both the reliability of the methods used and their relevance to the case, not just the expert's credentials.
When answering exam questions related to the Daubert Standard, clearly articulate both the relevance and reliability components, and apply the factors from the Daubert case to hypothetical scenarios.
