How Daubert v. Merrell Dow Pharmaceuticals, Inc. applies in California: state-specific rules, key cases, and bar exam notes for Evidence.
California generally follows the Frye standard for admissibility of expert testimony rather than the Daubert standard. However, since the California Supreme Court's decision in Sargon Enterprises, Inc. v. University of Southern California, it has moved closer to adopting a more Daubert-like analysis.
The rule in California permits expert testimony if the methods used are generally accepted in the scientific community, with further scrutiny of the validity and relevance of the testimony as highlighted in Sargon.
This case established that expert opinion must have foundational reliability to be admissible, aligning California’s approach more closely with Daubert.
The court held that expert testimony must be based on generally accepted scientific principles, reiterating the need for foundational reliability.
In this case, the court emphasized the requirement for expert testimony to rest on reliable methodologies that the expert can substantiate.
California's approach emphasizes general acceptance and reliability of expert testimony but has incorporated more rigorous evaluations reminiscent of Daubert. Unlike the federal standard, which is strictly focused on the expert's qualifications and methodology, California courts remain rooted in the general acceptance paradigm, though moving in a more analytical direction.
Understanding the nuances of California's approach to expert testimony and the evolution towards Daubert-like scrutiny can be critical for the California bar exam, especially in Evidence sections.
