What Is the Scope of Expert Discovery in New Mexico?
In New Mexico, the discovery of expert information is governed by a comprehensive framework that allows for detailed exploration of expert testimony, qualifications, and related materials. Under N.M. R. Civ. P. 1-026(B)(6)(c), parties can utilize interrogatories and requests for production to obtain information about testifying experts. This includes the expert's identity, the subject matter and substance of their testimony, the facts and opinions they will present, and the grounds for these opinions. Additionally, parties can inquire into the expert's qualifications, such as their publication history over the last decade and prior case testimonies from the past four years.
New Mexico's rules share some similarities with the Federal Rule of Civil Procedure 26(b)(4), particularly in the allowance for detailed expert discovery. However, certain nuances exist, such as the specific handling of non-testifying experts, which require a showing of exceptional circumstances for discovery. Limits on the discovery of expert communications, draft reports, or consulting expert materials are not explicitly addressed in the rules, though attorney work product is protected under Rule 1-026(B)(5).
Timing and Procedure for Expert Discovery in New Mexico
Expert discovery in New Mexico typically follows a procedural timeline established by the court's scheduling order. This order sets deadlines for expert disclosures and the exchange of expert reports, which is often required to occur by a specific date agreed upon by both parties. The timing of expert discovery usually takes place after initial disclosures and before trial.
Procedural steps for expert discovery involve serving interrogatories and requests for production to gather detailed expert information. Once experts are disclosed, depositions may be conducted. New Mexico permits the deposition of opposing experts, with a default limit of one seven-hour day unless court leave is granted. The applicable procedural rules guiding these processes include N.M. R. Civ. P. 1-026 for discovery and N.M. R. Civ. P. 1-037 concerning compliance.
What Methods of Expert Discovery Are Permitted in New Mexico?
In New Mexico, various methods are available for expert discovery, including:
- Interrogatories and Requests for Production: Used to obtain detailed information about expert testimony, qualifications, and reports.
- Depositions: Allowed for opposing experts, with a typical limit of one seven-hour session unless extended by court order.
Discovery primarily focuses on testifying experts, with consulting (non-testifying) experts being discoverable only upon a showing of exceptional circumstances, akin to federal standards. Privilege and work-product protections apply, though the extent to which these protections cover materials shared with experts remains unclear.
Limits on Discovery of Expert Materials and Communications
New Mexico's rules do not explicitly address the discoverability of draft reports or attorney–expert communications, leaving room for interpretation and potential court rulings to fill this gap. Rule 1-026(B)(5) provides a general protection for attorney work product, yet it does not clarify whether this protection extends to materials shared with experts.
Exceptions to the protections may arise in cases involving bias, reliance materials, or facts/data considered by the expert. Notably, state law requires early consultation with a qualified medical expert in medical malpractice cases, separate from the broader discovery process.
Consequences for Noncompliance or Discovery Violations
Failure to adhere to expert discovery rules in New Mexico can lead to significant consequences. Under Rule 1-037, a party may face the exclusion of an undisclosed expert at trial if they fail to provide the required information. Other potential sanctions include continuances and monetary penalties, emphasizing the importance of compliance with procedural requirements.
