Connecting Lawyers with Expert Witnesses

On June 7, 2022, a significant development took place within the realm of expert witness testimony: the Judicial Conference Committee on Rules of Practice and Procedure approved amendments to several Federal Rules of Evidence, with a notable focus on Rule 702. This rule governs the admissibility of expert witness testimony in legal proceedings. If these amendments are approved by both the US Supreme Court and Congress, they will come into effect on December 1, 2023. This article delves into the key changes introduced by the Rule 702 amendment, its intended impact, and the best practices attorneys and expert witnesses should consider in light of these changes.

The Aim of the Rule 702 Amendment

The primary objective of the Rule 702 amendment is to clarify the existing rule. The change addresses a longstanding issue where some federal judges misinterpreted the original rule to mean that evidence could be admitted if a jury might find it reliable, rather than the judge being responsible for making that determination. This interpretation blurred the lines between the roles of judges and juries in determining the admissibility of expert testimony. To rectify this, the amendment emphasizes that expert testimony may only be admitted if the proponent demonstrates to the court that it is "more likely than not" that the testimony meets the admissibility criteria outlined in the rule.

US District Judge Patrick Schiltz, who chairs the Advisory Committee on Evidence Rules and supports the amendment, clarifies that this change does not alter the existing law but rather makes it more transparent. This amendment is expected to provide a clearer framework for judges to assess the admissibility of expert testimony, leading to a more consistent application of the rule across federal courts.

The Amendment in Practice

The Rule 702 amendment introduces two key changes to the rule:

1. **Admissibility Standard**: The amended rule explicitly states that expert testimony can only be admitted if it is "more likely than not" that the testimony meets the criteria for admissibility. This standard is substantively equivalent to the "preponderance of the evidence" standard, which is already applicable to many admissibility requirements in evidence rules.

2. **Reliable Application**: The second aspect of the amendment highlights that an expert's testimony must not only be grounded in reliable principles and methods but also demonstrate a reliable application of these principles and methods to the specific facts of the case.

 Implications for Attorneys and Expert Witnesses

The Rule 702 amendment heralds a significant shift in how expert testimony is evaluated and admitted. Attorneys and expert witnesses must be prepared to adapt to these changes to ensure their testimony remains admissible and effective in court. Here are some best practices for both parties:

1. **Evaluate Communication Skills**: Attorneys should assess potential expert witnesses for their communication skills, especially their ability to explain complex concepts clearly. The expert's capability to connect with judges and jurors and present information in an understandable manner becomes crucial.

2. **Emphasize Teaching Abilities**: Expert witnesses should focus on being effective teachers. The ability to translate intricate technical details into relatable explanations is essential, particularly for cases involving complex subjects.

3. **Thorough Preparation**: Attorneys must work closely with expert witnesses to ensure they understand the basis of their opinions and can convey them convincingly. Collaboration is key to constructing compelling and reliable testimonies.

4. **Early Engagement**: Engaging an expert witness early in the case allows for better preparation and ownership of the analysis and reporting. It helps ensure that the expert's testimony is well-supported and credible.

5. **Understand Admissibility Criteria**: Both attorneys and expert witnesses must be well-versed in the amended Rule 702 and its stringent admissibility standards. Familiarity with the principles and methodology underlying an expert's opinion is essential for presenting a strong case.

Conclusion

The Rule 702 amendment signifies a significant step toward enhancing the clarity and reliability of expert witness testimony in legal proceedings. By emphasizing a higher standard of admissibility and the importance of a reliable application of principles, the amendment seeks to create a more consistent and equitable approach to evaluating expert testimony. Attorneys and expert witnesses alike should be proactive in understanding and adapting to these changes to ensure their contributions remain valuable and admissible in the evolving legal landscape.
