Arkansas Expert Witness Admissibility Rules

Overview of Expert Witness Admissibility in Arkansas

In Arkansas, the admissibility of expert witness testimony is a critical aspect of both civil and criminal litigation. Expert witnesses play a pivotal role in assisting the court by providing opinions on complex matters that require specialized knowledge. The admissibility of such testimony is governed by specific legal standards that ensure the reliability and relevance of the expert's opinion. An understanding of these standards is essential for attorneys to effectively navigate the litigation landscape in Arkansas.

Is Arkansas a Daubert or Frye State?

Arkansas follows the Daubert standard, which is derived from the landmark U.S. Supreme Court case Daubert v. Merrell Dow Pharmaceuticals, Inc., 509 U.S. 579 (1993). This standard supersedes the earlier Frye standard that required scientific evidence to be "generally accepted" in its field. Under Daubert, the focus shifts to the scientific validity and applicability of the expert's methodology. The Arkansas Supreme Court adopted the Daubert standard in Farm Bureau Mutual Ins. Co. of Arkansas, Inc. v. Foote, 341 Ark. 105 (2000), emphasizing that trial judges must act as "gatekeepers" to ensure that expert testimony is both relevant and reliable.

Understanding Arkansas Rule of Evidence 702

Arkansas Rule of Evidence 702 mirrors the federal rule and is foundational to the admissibility of expert testimony. It states:

"A witness who is qualified as an expert by knowledge, skill, experience, training, or education may testify in the form of an opinion or otherwise if:

1. The expert's scientific, technical, or other specialized knowledge will help the trier of fact to understand the evidence or to determine a fact in issue;
2. The testimony is based on sufficient facts or data;
3. The testimony is the product of reliable principles and methods; and
4. The expert has reliably applied the principles and methods to the facts of the case."

This rule underscores the importance of both the expert's qualifications and the reliability of their methodology.

Factors Courts Consider When Admitting Expert Testimony in Arkansas

When determining the admissibility of expert testimony, Arkansas courts consider several key factors:

• Qualifications of the Expert: The expert must demonstrate adequate education, skill, or experience relevant to the matter at hand.
• Relevance and Helpfulness: The testimony must assist the jury in understanding the evidence or determining a fact in issue, as highlighted in the case of Williams v. State, 343 Ark. 591 (2001).
• Reliability of Methodology: The principles and methods used by the expert must be scientifically valid and reliably applied to the facts of the case.
• Peer Review and Publication: The extent to which the methodology has been subject to peer review and publication can be indicative of its acceptance in the scientific community.

Common Challenges to Expert Admissibility in Arkansas

Challenges to expert admissibility often arise due to:

• Lack of Qualifications: Opposing counsel may argue that the expert lacks the necessary qualifications or expertise.
• Unreliable Methodology: An expert's methodology may be challenged if it lacks scientific rigor or is not widely accepted.
• Bias or Conflict of Interest: Concerns about the expert's objectivity can lead to challenges, as seen in McNabb v. State, 367 Ark. 93 (2006).
• Failure to Apply Principles Reliably: Even if the methodology is sound, failure to reliably apply it to the case facts can result in exclusion.

• Thoroughly Vet Experts: Ensure that the expert's qualifications are impeccable and relevant to the case.
