N.M. Admin. Code § 13.21.5.19 - WITNESSES, EXPERT WITNESSES, AND INVOCATION OF THE RULE

A. Use of witnesses. Any person having relevant, material knowledge related to one of the issues in a hearing may testify as a witness under oath in a proceeding. Upon affirming the oath, the witness may be questioned by any party and by the advisory board.

B. Method of appearance. Unless a more specific provision applies, witnesses are ordinarily expected to appear in the same manner or by the same method as the parties in a proceeding, absent express preapproval of the advisory board allowing an appearance by a different method. For example, if the hearing is scheduled to be conducted in person in a specific place, the witnesses are also ordinarily expected to appear in person at that same place; however, if the matter is set to occur by telephone or videoconference, then the witnesses may ordinarily appear by telephone of videoconference.

C. Advisory board as a witness. The current or previously assigned advisory board in a matter shall not be called and shall not be a witness in the proceeding.

D. Use of expert witnesses.

(1) If either party intends to call and treat a particular witness as an expert witness in the proceeding, the party must identify the purported expert to the other parties and to the advisory board at least seven days before the scheduled hearing, or with sufficient time before completion of the discovery deadline specified in a scheduling order to allow for deposition.

(2) The party shall include the scope of that expert's purported testimony relative to the proceeding, the expert's credentials, and a listing of any materials the expert reviewed as part of reaching his or her expert opinion.

(3) The opposing party may file a response in opposition before the hearing or challenge the designation of the witness as an expert during the course of the hearing.

E. Use of exclusionary rule. At the hearing, any party can invoke the exclusionary rule, excluding all witnesses other than the real party in interest, their representative, one main case agent, and any designated expert witness from the proceeding until the time of their testimony. If the rule has been invoked, the witnesses shall not discuss their testimony with each other until the conclusion of the proceeding. When the rule has been invoked, any witness who remains in the hearing after conclusion of their testimony may not be recalled as a witness in the proceeding, except that any witness may observe the testimony of an expert witness and be recalled to provide any subsequent rebuttal testimony.

F. OSI staff as experts.

(1) The advisory board may request one or more members of OSI staff to be present at the hearing to assist the advisory board with any matters within the expertise of the staff person.

(2) The staff person may be called as a witness by the advisory board and examined by the parties and the advisory board.

(3) Any party may call the staff person as a witness.

(4) Each other party will have the opportunity to cross-examine a staff person who is called as a witness. In the discretion of the advisory board, the advisory board may permit re-direct or re-cross examination of the staff person.

(5) The advisory board shall not discuss the case with the staff person outside the hearing or off the record.

(6) Any staff person requested to be present by the advisory board shall not be subject to the exclusionary rule.
