An Experts Guide to Expert Witness Preparation

It should come as no surprise to those reading this article that preparing expert witnesses for Daubert challenges is a critical aspect of trial preparation for attorneys. The Daubert standard, established by the U.S. Supreme Court in 1993, governs the admissibility of expert testimony in federal courts. It requires that expert testimony be based on reliable scientific methodology and be relevant to the issues at hand.

Daubert challenges can have a significant impact on expert witnesses, often causing them to feel nervous and apprehensive. The Daubert standard sets a high bar for the admissibility of expert testimony, requiring that it be based on reliable scientific methodology. This level of scrutiny can create a sense of pressure and unease for expert witnesses, who may fear that their qualifications, expertise, and credibility will be called into question.

Expert witnesses often rely on their expertise and credibility to secure future engagements and maintain their standing within their field. A failed Daubert challenge can tarnish an expert’s reputation, leading to a loss of credibility and opportunities for future work. The fear of damaging their professional reputation can create anxiety and stress for expert witnesses, making them more prone to nervousness and during testimony, something a trier of fact, regardless of objectivity, normally will take note of.

Moreover, the complexity of the Daubert standard itself can be a source of anxiety for expert witnesses. The standard requires a thorough evaluation of the methodology used by the expert, including factors such as testing, peer review, potential error rates, and general acceptance. Expert witnesses may worry about whether their methodology will meet these stringent requirements and whether they will be able to effectively explain and defend their approach during the Daubert challenge. The fear of being unable to meet the court’s expectations can only exacerbate the expert’s unease.

Accordingly, preparation of an expert witness is critical to not only settle the nerves of the expert you are working with, but more importantly, will enhance their credibility with the judge or jury. We have capitalized on our years of experience in working with experts to provide the following checklist any attorney should go through when preparing an expert for a Daubert challenge.

1. Select the Right Expert:

The first step in preparing for a Daubert challenge is to select the right expert. Choose an expert who has the necessary qualifications, expertise, and experience in the relevant field. Ensure that they have a strong track record of providing reliable and credible testimony in previous cases. We are here to help with that!

2. Understand the Daubert Standard:

To effectively prepare an expert witness for a Daubert challenge, it is crucial for trial attorneys to have a thorough understanding of the Daubert standard. Familiarize yourself with the factors considered by the courts, such as whether the theory or technique has been tested, whether it has been subjected to peer review, the known or potential rate of error, and the general acceptance in the scientific community.

3. Evaluate the Expert’s Methodology:

Carefully evaluate the expert’s methodology and ensure that it meets the requirements of the Daubert standard. Review their research, experiments, data analysis, and any other techniques they used to arrive at their conclusions. Verify that their methodology is reliable, objective, and based on sound scientific principles.

4. Identify Potential Weaknesses:

Thoroughly analyze the expert’s methodology and identify any potential weaknesses or vulnerabilities. Scrutinize their data collection methods, assumptions, limitations, and any gaps in their analysis. Anticipate the opposing counsel’s arguments and potential challenges to the expert’s methodology.

5. Conduct Pre-Deposition Preparation:

Before the deposition, meet with the expert witness to prepare them for potential Daubert challenges. Review the expert’s methodology, the relevant scientific literature, and any relevant court decisions. Discuss the Daubert factors and how the expert’s testimony meets the standard. Address any potential weaknesses and provide guidance on how to respond to challenges during deposition. We will be releasing an article next week addressing this topic in greater detail.

6. Strengthen the Foundation:

Work with the expert witness to strengthen the foundation of their opinions. Walk through with the expert the data or opinions they plan to offer and how the testimony connects with the facts of the case. This will demonstrate a robust and reliable methodology, increasing the chances of withstanding a Daubert challenge.

7. Create a Daubert Binder:

Assemble a comprehensive Daubert binder containing all the relevant materials that support the expert’s methodology and opinions. Include scientific articles, research papers, studies, reports, and any other evidence that bolsters the credibility of the expert’s testimony. Organize the binder in a logical and easy-to-navigate manner.

8. Conduct Mock Daubert Challenges:

Simulate a Daubert challenge by conducting mock challenges with the expert witness. Have another attorney or a colleague play the role of the opposing counsel and challenge the expert’s methodology. This exercise will help the expert become familiar with the possible lines of attack and develop strong rebuttals.

9. Prepare for Cross-Examination:

In addition to the Daubert challenge, the expert witness will also face cross-examination from the opposing counsel. Prepare the expert for potential cross-examination strategies and help them develop effective responses. Role-play different cross-examination scenarios to improve the expert’s ability to handle challenging questions.

10. Document the Preparation:

The first step in preparing for a Daubert challenge is to select the right expert. Choose an expert who has the necessary qualifications, expertise, and experience in the relevant field. Ensure that they have a strong track record of providing reliable and credible testimony in previous cases. We are here to help with that!
