What does the Daubert case address regarding testimony?

The Daubert case addresses the factors that determine the reliability of expert testimony, focusing on the standard for admitting expert evidence in court. In this landmark decision, the U.S. Supreme Court ruled that judges have a gatekeeping role in assessing whether an expert's scientific testimony is both relevant and reliable. This involves evaluating the methodology and principles underlying the expert's conclusions. Key elements that judges consider include whether the theory or technique in question can be and 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 relevant scientific community. By establishing these criteria, the Daubert ruling provides a framework that ensures that only scientifically valid and relevant expert testimony is presented in court, thereby enhancing the integrity of the judicial process.
