Which court case established that the Daubert standard applies to skill-based evidence?

The case that established the application of the Daubert standard to skill-based evidence is Kumho Tire v. Carmichael. This ruling clarified that the Daubert standards for admissibility of scientific evidence also extend to expert testimony based on specialized knowledge or skills, beyond just scientific analysis. Before this case, the Daubert standard primarily addressed scientific testimony. The Kumho Tire decision confirmed that judges have a responsibility to evaluate the reliability of all forms of expert evidence, including those from practical experience, ensuring that the testimony is not only reliable but also relevant to the case at hand.

In this context, Daubert v. Merrell Dow Pharmaceuticals, Inc. laid the groundwork for the standard of reliability in scientific testimonies but did not address skill-based evidence. Frye v. United States predates both Daubert and Kumho Tire, focusing on the "general acceptance" standard, which is narrower than the Daubert standard. Miranda v. Arizona, while significant in legal history, deals with the rights of the accused and does not pertain to evidentiary standards. Thus, Kumho Tire’s ruling plays a pivotal role in allowing for the inclusion of expert testimony from various fields while ensuring its reliability through the lens of the Daubert standard.
