Colleen Nix v. New Mexico Department of Public Safety, et al.

Trial Court Opinion

IN THE UNITED STATES DISTRICT COURT

FOR THE DISTRICT OF NEW MEXICO

COLLEEN NIX,

Plaintiff, v. No. 1:24-cv-00691-KG-LF NEW MEXICO DEPARTMENT

OF PUBLIC SAFETY, et al.,

Defendants.

ORDER TO SUPPLEMENT

This matter is before the Court on Plaintiff Colleen Nix’s Motion to Exclude Affidavit and Testimony of Dr. Steven Fishburn, Doc. 110, and Defendant Kevin Keiner’s Response, Doc. 129. Defendant, as the proponent of the challenged expert testimony, bears the burden of establishing its admissibility by a preponderance of the evidence. United States v. Nacchio, 555 F.3d 1234, 1241 (10th Cir. 2009). Although Defendant submitted an affidavit from Dr. Fishburn in support of summary judgment, Doc. 50-6, the present record is insufficient for the Court to evaluate the admissibility of the proposed testimony under Rule 702 and Daubert.

Therefore, Defendant must supplement the record within 14 days of this Order by filing any expert report prepared by Dr. Fishburn. If no report exists, Defendant must explain why no report was required and disclose: (1) Dr. Fishburn’s opinions; (2) his methodology; and (3) the facts and materials considered. After supplementation, the Court will determine whether a Daubert hearing is necessary.

IT IS SO ORDERED. /s/Kenneth J. Gonzales___________________ CHIEF UNITED STATES DISTRICT JUDGE • Please note that this document has been electronically filed.
