Daubert Standard (Test)

Definition

The Daubert Standard (Test) is a legal rule that dictates the admissibility of expert witness testimony in court proceedings. Implemented to ensure that the testimony provided by experts is both relevant and reliable, this standard was established in the 1993 Supreme Court case of Daubert v. Merrell Dow Pharmaceuticals, Inc.. The Daubert Standard allows judges to act as “gatekeepers” in admitting expert testimony, whether it pertains to scientific or other technical issues. The scope of the Daubert Standard was further broadened by the 1999 case Kumho Tire Co. v. Carmichael, extending its application beyond purely scientific testimony to all expert testimony.

Examples

Scientific Testimony: In a personal injury case involving pharmaceutical drugs, an expert’s testimony on the drug’s side effects must demonstrate that the methods and principles underpinning the expert’s analysis are scientifically valid and reliably applied to the facts of the case.
Technical Testimony: In an automotive defect case, an engineer’s expert testimony regarding the design defect of a vehicle would need to pass the Daubert Standard, confirming that the principles and methodology used to derive the opinion are pertinent and based on sound engineering practices.

Frequently Asked Questions (FAQs)

Q1: What is the purpose of the Daubert Standard?
A1: The Daubert Standard ensures that expert witnesses provide testimony that is both relevant and reliable, preventing unreliable or unqualified testimony from affecting the court’s judgment.

Q2: What factors does a judge consider under the Daubert Standard?
A2: Judges consider several factors, including whether the expert’s theory or technique has been tested, whether it has been peer-reviewed and published, the known or potential error rate, and the acceptance within the relevant scientific community.

Q3: How does the Daubert Standard differ from the Frye Standard?
A3: The Frye Standard, established in Frye v. United States, focuses mainly on whether the expert’s methodology has gained “general acceptance” in its field. The Daubert Standard, on the other hand, is more flexible and considers a broader range of factors related to the reliability and relevancy of the testimony.

Q4: What case extended the Daubert Standard to all expert testimony?
A4: The case Kumho Tire Co. v. Carmichael extended the Daubert Standard to all expert testimony, not just scientific testimony.

Q5: Is the Daubert Standard applied in all U.S. courts?
A5: The Daubert Standard is the law in federal courts and in more than half of the state courts. However, some states still adhere to the Frye Standard or the less rigorous Robinson Standard.

Frye Standard: A legal standard used to determine the admissibility of scientific evidence, focusing on whether the method employed by the expert is generally accepted by the scientific community.
Robinson Standard: Another evidentiary standard used in some jurisdictions, focusing less rigorously on the assessment criteria compared to the Daubert Standard.
Kumho Tire Co. v. Carmichael: A U.S. Supreme Court case extending the Daubert Standard to all expert testimonies.
Expert Witness: A witness with specialized knowledge, skill, experience, training, or education that qualifies them to provide opinions to aid the court in understanding evidence or determining facts.
