Who bears the gatekeeping responsibility for the admissibility of expert testimony under Daubert/Kelly?

• A. The jury
• B. The trial court
• C. The opposing party
• D. The expert

Answer: (B)

Under Daubert/Kelly, the gatekeeping role for expert testimony rests with the trial judge. The judge must decide, before the testimony is presented to the jury, whether the expert’s methodology is scientifically valid and properly applicable to the facts at hand. This involves evaluating reliability and relevance, typically considering factors like whether the method can be tested, has been peer-reviewed, has known error rates, follows standards for data collection and analysis, and enjoys general acceptance in the relevant field. The aim is to ensure the evidence will assist the trier of fact and not mislead. The jury does not determine admissibility; they weigh the testimony after it’s admitted, using cross-examination and argument to assess credibility and value. The opposing party can object and present counter-evidence, but the decision to admit or exclude lies with the court, with appellate review for abuse of discretion if challenged.
