What is a Daubert Challenge in expert testimony?

A Daubert Challenge tests whether an expert's methodology is scientifically valid and relevant. It serves as a gatekeeping mechanism that allows courts to determine whether expert opinions meet the admissibility standards outlined in Federal Rule of Evidence 702.

The challenge scrutinizes the scientific foundation and applicability of an expert's proposed testimony before it can be presented to a jury. This process protects the integrity of judicial proceedings by ensuring that expert witnesses rely on sound methodologies rather than speculation or unreliable techniques.
