North Dakota Expert Witness Discovery Rules

What Is the Scope of Expert Discovery in North Dakota?

In North Dakota, the scope of expert discovery is governed by rules that closely mirror the federal framework, specifically under the North Dakota Rules of Civil Procedure (N.D. R. Civ. P. 26(b)(4) and 26(a)(2)). Under these rules, parties are required to disclose the identity of any expert witness they wish to use at trial. For retained experts, a comprehensive written report prepared and signed by the expert is mandatory. This report must include the expert’s opinions, the basis and reasons for those opinions, the data considered, any exhibits, qualifications, a list of cases testified in the last four years, and the compensation to be paid, aligning closely with the Federal Rules of Civil Procedure 26(a)(2)(B).

The discovery of expert communications, draft reports, and consulting expert materials in North Dakota is subject to stringent limitations. Consistent with the federal protections, draft reports and attorney–expert communications are generally not discoverable. Exceptions exist for communications regarding the expert's compensation and facts or assumptions provided by counsel for use in forming the opinions (N.D. R. Civ. P. 26(b)(4)(C)).

Timing and Procedure for Expert Discovery in North Dakota

The timing of expert discovery in North Dakota is primarily dictated by the court's scheduling order. Initial expert reports are generally required 90 days before trial, with rebuttal reports due 30 days thereafter. This timeline ensures that expert discovery occurs well before the trial, allowing for comprehensive preparation. Experts may be deposed following the submission of their reports, providing both parties an opportunity to examine the expert testimony thoroughly.

The procedural steps for expert discovery include the exchange of expert reports, conducting depositions, and potentially serving interrogatories and requests for production. Adherence to these steps is governed by N.D. R. Civ. P. 26(a)(2) and supplemented by N.D. R. Civ. P. 26(e), which mandates the supplementation of expert disclosures in the event of material changes.

What Methods of Expert Discovery Are Permitted in North Dakota?

In North Dakota, parties are permitted to engage in several methods of expert discovery, including depositions, written interrogatories, and document requests. These methods, however, are primarily applicable to testifying experts. Discovery related to consulting experts is significantly restricted and generally requires a demonstration of exceptional circumstances or a substantial need, aligning with federal standards.

• Depositions: Allowed following the provision of expert reports, facilitating detailed examination of expert opinions.
• Interrogatories and Document Requests: Utilized to obtain relevant written information and documents from expert witnesses.

The state maintains a similar approach to privilege and work-product protections as the federal system, safeguarding communications between counsel and experts, except under specified conditions.

Limits on Discovery of Expert Materials and Communications

North Dakota's approach to the discovery of expert materials and communications is aligned with federal protections. Draft reports and attorney–expert communications are shielded from discovery, except in cases involving compensation details and facts or assumptions provided by counsel (N.D. R. Civ. P. 26(b)(4)(B)&(C)). The rationale for these limitations is to encourage open communication between attorneys and experts without fear of disclosure.

Exceptions to these limitations are minimal and typically involve matters showing potential bias or the facts and data considered by the expert. There is no significant state case law deviating from these standards, ensuring consistency with federal practices.

Consequences for Noncompliance or Discovery Violations

Noncompliance with expert discovery rules in North Dakota can result in severe consequences. Under N.D. R. Civ. P. 37(c)(1), failure to disclose an expert or provide the required report results in the automatic exclusion of that expert's testimony at trial unless the failure was substantially justified or deemed harmless. This rule underscores the importance of strict adherence to procedural requirements.

Potential sanctions for discovery violations include:

• Exclusion of Testimony: Automatic unless justified or harmless.
• Continuances: Possible adjustments to the trial schedule to accommodate compliance.
• Monetary Sanctions: Financial penalties for failure to adhere to discovery obligations.
