Daubert hearings are special court sessions where judges decide if the scientific reasoning behind an expert’s testimony is solid and can be trusted in a case.

Daubert hearings are crucial for mass torts because they help ensure that the scientific evidence presented by experts is reliable and valid. 

In mass tort cases, where many people may be affected, the accuracy of expert testimony is vital in determining the outcome of the case.

 If a Daubert hearing finds that an expert’s testimony is not based on solid scientific reasoning, it can significantly impact the plaintiffs’ claims and the overall outcome of the mass tort litigation.

 In complex Mass Torts Plaintiffs are required to support their claims with expert testimony. If following a Daubert hearing the judge rules that an expert’s testimony is unreliable and inadmissible, the case is basically over. 

Due to the enormous consequences a Daubert challenge can have, it is important for any practicing trial attorney to understand how to execute a Daubert challenge, when to do so, and strategies relating to the execution of such a challenge.

Let’s understand the What Daubert Motions, Hearings, and Rulings mean

Difference between Daubert Motions, Hearings, and Rulings are all components of a legal process related to the admissibility of expert testimony in a court case, particularly in the United States. 

Daubert Motions:

In summary, Daubert motions are requests made to the court, Daubert hearings are court proceedings where arguments and evidence are presented, and Daubert rulings are the judge’s final decisions on whether the expert testimony is allowed in the trial. These processes help ensure that only scientifically valid and reliable expert testimony is presented in court.

A classic example of Daubert hearing is the Zantac MDL . The trial judge excluded all of Plaintiffs’ experts from testifying and essentially ended the MDL.

The Zantac Daubert hearings began in September 2022. In the Zantac litigation, the plaintiffs needed expert testimony to prove their claims that they developed cancer from NDMA in Zantac. 

Eventually, after conducting a three-day “Daubert hearing,” Judge Robin Rosenberg dismissed the entire cadre of plaintiffs’ scientific evidence. 

There will be a Daubert hearing in the Paraquat MDL that will determine the future of this Mass Tort in the next few weeks. Later this year, this will be a Daubert hearing in the Tylenol Mass Tort. 

These hearings will shape the future of Mass Torts in 2024 and beyond.
