Arkansas Expert Witness Report Rules

Are Expert Witness Reports Required in Arkansas?

In Arkansas, the disclosure of expert witnesses is guided by the state's discovery rules, specifically Arkansas Rules of Civil Procedure 26(b)(4). Unlike some jurisdictions, Arkansas does not automatically mandate formal written reports from expert witnesses. However, parties may be required to identify any expert witness intended for use at trial and provide the substance of the expert’s expected testimony. This information can be gathered through interrogatories or requests for reports. The rule also allows for the deposition of the expert following these disclosures.

Disclosure deadlines are typically determined by court scheduling orders, with deadlines often set during the discovery phase. Failure to comply with these timelines can lead to the exclusion of the expert's testimony under Ark. R. Civ. P. 37.

What is Required in an Arkansas Expert Witness Report?

While Arkansas does not require formal written reports by default, when such reports are requested, they typically include:

• The opinions the expert is expected to offer.
• The bases and reasons for those opinions.
• Data or information considered in forming the opinions.
• Any exhibits that will be used to support the opinions.
• The expert's qualifications, including publications.
• The expert's compensation for their involvement in the case.

Arkansas courts rely heavily on the substance of the expert's expected testimony as disclosed through interrogatories or other discovery tools, rather than strictly adhering to a federal-style report requirement.

Scope and Authorship of the Report

In Arkansas, the scope of an expert witness report varies based on the type of testimony or the complexity of the case. The report can be drafted by the expert or in collaboration with legal counsel, although the expert usually must sign it to authenticate its contents. Attorney involvement is permissible but should not overshadow the expert's own analysis and opinions. The extent of permissible attorney involvement must ensure the authenticity and reliability of the expert’s conclusions.

Missing, Deficient, and Untimely Reports

Arkansas courts have specific responses to missing, deficient, or untimely expert witness disclosures:

• Exclusion of Testimony: A primary sanction for failure to disclose expert information as required is the exclusion of the expert’s testimony at trial.
• Sanctions: Under Ark. R. Civ. P. 37, courts may impose various sanctions, including awarding attorney fees or other penalties.
• Continuances: In some cases, courts may grant a continuance to allow for proper disclosure or correction of deficiencies.

Such consequences underscore the importance of adhering to disclosure deadlines and ensuring the completeness of expert disclosure.

Original, Supplemental, and Rebuttal Reports

Arkansas procedural rules do not explicitly use the terms “supplemental” or “rebuttal” reports as seen in federal practice. However, the state allows for updates to expert disclosures if new information emerges or if there are changes in the expert’s opinions. These updates must be provided in a timely manner, as dictated by the court’s scheduling orders or as necessary to prevent undue prejudice.

Courts in Arkansas handle disputes over these disclosures by evaluating the necessity and timing of the updates, often focusing on whether the updates are materially new or merely clarifications of previous disclosures.

Relevant State Rules and Legal Requirements

The primary rule governing expert disclosures in Arkansas is Rule 26, which outlines the conditions under which expert information must be shared. The rule’s application is interpreted through various court orders and case law, which provide additional guidance on timing and content of disclosures. Notably, the rule does not directly replicate federal standards and is customized to fit the state’s procedural framework.

Arkansas courts emphasize the need for timely and thorough disclosures, aligning with the overall discovery process to ensure fairness and preparation for trial. The state’s approach demonstrates a balance between flexibility in expert reporting and the need for comprehensive disclosure to facilitate just outcomes in litigation.
