Nevada Expert Witness Discovery Rules

What Is the Scope of Expert Discovery in Nevada?

In Nevada, the scope of expert discovery is framed extensively, aligning closely with federal standards. Nevada Rule of Civil Procedure 16.1(a)(2) mandates comprehensive disclosures regarding expert witnesses. Parties must disclose the identity of any expert witness expected to testify at trial and, if retained specifically for testimony, provide a detailed expert witness report prepared and signed by the expert. This report should include:

• A complete statement of all opinions the expert will present, including the basis and reasons for these opinions.
• The facts or data considered by the expert.
• Any exhibits that will be used to support the opinions.
• The expert’s qualifications, including publications over the last decade.
• A list of cases in which the expert has testified in the past four years.
• The compensation to be paid to the expert.

Nevada has adopted a framework similar to Federal Rule of Civil Procedure 26(b)(4), with protections in place for draft reports and most attorney-expert communications, as detailed in Nev. R. Civ. P. 26(b)(5). This rule shields drafts and communications except those concerning compensation or facts and assumptions provided by the attorney.

Timing and Procedure for Expert Discovery in Nevada

Expert discovery in Nevada typically occurs on a timeline set forth by scheduling orders, generally due 90 days before the discovery cutoff. Rebuttal expert disclosures are required within 30 days after the initial disclosures by the opposing party. These timelines ensure that expert discovery precedes the trial, allowing adequate time for deposition and examination of the expert materials exchanged.

Procedural steps for expert discovery include:

• Exchanging Expert Information: Parties must exchange the required expert reports as per Nev. R. Civ. P. 16.1(a)(2).
• Deposing Experts: Deposition of experts is permissible after the exchange of reports, providing an opportunity to explore the foundation and scope of the expert's opinions.
• Supplementing Disclosures: Under Nev. R. Civ. P. 26(e), parties are under a continuous obligation to supplement disclosures if new information emerges.

What Methods of Expert Discovery Are Permitted in Nevada?

Nevada permits a range of discovery methods for experts, primarily focusing on testifying experts. These methods include:

• Depositions: Once expert reports are exchanged, experts can be deposed to assess their testimony and underlying assumptions.
• Written Interrogatories and Document Requests: These are limited to the information necessary to understand the expert's opinions and the basis for them.
• Privilege and Work-Product Protections: Nevada protects draft reports and attorney-expert communications, similar to federal standards, barring few exceptions.

The discovery of consulting experts, who are not expected to testify, is generally restricted unless exceptional circumstances are demonstrated.

Limits on Discovery of Expert Materials and Communications

Nevada's approach to expert discovery includes safeguards against overly broad intrusions into expert materials and communications. Draft reports and most communications between attorneys and experts are protected under Nev. R. Civ. P. 26(b)(5), which mirrors federal Rule 26(b)(4). However, exceptions include:

• Compensation Details: Information regarding the expert's compensation remains discoverable.
• Facts/Data Provided: Any facts or assumptions provided by the attorney to the expert can be subject to discovery.

Significant case law may further interpret these rules, though Nevada's framework largely aligns with federal standards.

Consequences for Noncompliance or Discovery Violations

Failure to comply with Nevada's expert discovery rules can lead to significant consequences. Under Nev. R. Civ. P. 37(c)(1), noncompliance with disclosure requirements can result in:

• Exclusion of Expert Testimony: Mandatory exclusion of an expert's testimony if the party fails to properly disclose the expert or their report by the deadline.
• Sanctions: Additional sanctions may include monetary penalties or other court-imposed remedies, unless the failure is substantially justified or harmless.
