Opinion

IN THE UNITED STATES DISTRICT COURT FOR THE DISTRICT OF COLORADO Judge Nina Y. Wang

Civil Action No. 23-cv-02115-NYW-TPO

PAUL CHANCELLOR, and NATALIE MAKARA,

Plaintiffs,

v.

STATE FARM MUTUAL AUTOMOBILE INSURANCE COMPANY,

Defendant.

MEMORANDUM OPINION AND ORDER

This matter is before the Court on Defendant’s Fed. R. Evid. 702 Motion to Limit the Opinions of Plaintiffs’ Expert Aaron Castillo (the “Motion to Exclude”), [Doc. 63], and Defendant’s Motion for Summary Judgment, [Doc. 64]. The Court has reviewed the Motions and concludes that oral argument would not materially assist in their resolution. For the reasons set forth below, the Motion to Exclude is GRANTED in part and DENIED in part and the Motion for Summary Judgment is GRANTED in part and DENIED in part. BACKGROUND At all relevant times, Plaintiffs Paul Chancellor and Natalie Makara (together, “Plaintiffs”) were insured through Defendant State Farm Mutual Automobile Insurance Company (“Defendant” or “State Farm”). [Doc. 6 at ¶¶ 3–4]. In 2023, their vehicle was damaged in a collision, and Plaintiffs took the car to Nylund’s Collision Center (“Nylund’s”) for repairs. [Id. at ¶¶ 3, 5]. State Farm only reimbursed Plaintiffs for a portion of the amount charged by Nylund’s. [Doc. 64 at ¶¶ 16, 21; Doc. 66 at ¶¶ 16, 21]. Plaintiffs subsequently sued State Farm, asserting one breach of contract claim, one claim of unreasonable delay or denial of insurance benefits under Colo. Rev. Stat. §§ 10-3-1115 and -1116, and one claim of common law bad faith. [Doc. 6 at 3–4]. In its Motion for Summary Judgment, State Farm asks the Court to enter summary

judgment in its favor on each of Plaintiffs’ claims. [Doc. 64]. State Farm also moves to exclude the testimony of Plaintiffs’ insurance industry expert, Aaron Castillo. [Doc. 63]. The Motions are fully briefed and ripe for resolution. I. The Motion to Exclude A. Legal Standard Rule 702 of the Federal Rules of Evidence states: A witness who is qualified as an expert by knowledge, skill, experience, training, or education may testify in the form of an opinion or otherwise if the proponent demonstrates to the court that it is more likely than not that:

(a) the expert’s scientific, technical, or other specialized knowledge will help the trier of fact to understand the evidence or to determine a fact in issue;

(b) the testimony is based on sufficient facts or data;

(c) the testimony is the product of reliable principles and methods; and

(d) the expert’s opinion reflects a reliable application of the principles and methods to the facts of the case.

Fed. R. Evid. 702. “Rule 702 permits a court to admit expert testimony that is ‘both reliable and relevant.’” Sanderson v. Wyo. Highway Patrol, 976 F.3d 1164, 1172 (10th Cir. 2020) (quoting United States v. Rodriguez-Felix, 450 F.3d 1117, 1122 (10th Cir. 2006)). The proponent of expert testimony has the burden to show its admissibility by a preponderance of the evidence. Squires ex rel. Squires v. Goodwin, 829 F. Supp. 2d 1041, 1048 (D. Colo. 2011). Trial courts are charged with the responsibility of acting as gatekeepers to ensure that expert testimony is reliable and relevant. See Kumho Tire Co. v. Carmichael, 526 U.S. 137, 147–52 (1999); Daubert v. Merrell Dow Pharms., Inc., 509 U.S. 579, 588–89 (1993). To fulfill that gatekeeper function, the trial court first analyzes whether the

proffered expert is qualified “by knowledge, skill, experience, training, or education” to render their opinions. Fed. R. Evid. 702; Bill Barrett Corp. v. YMC Royalty Co., 918 F.3d 760, 770 (10th Cir. 2019). If the expert is qualified, the court must determine whether the expert’s opinions are reliable by assessing the underlying reasoning and methodology. Bill Barrett Corp., 918 F.3d at 770. The court must also determine whether the expert’s opinions are “applicable to a particular set of facts,” i.e., are relevant to the case at hand. Dodge v. Cotter Corp., 328 F.3d 1212, 1221 (10th Cir. 2003). This inquiry “encompasses Rule 702’s requirement that the evidence help the trier of fact to understand the evidence or to determine a fact in issue.” Sanderson, 976 F.3d at 1172 (cleaned up). B. Analysis

Plaintiffs designated Mr. Castillo to testify about “State Farm’s errors in the estimating and supplemental estimating processes, State Farm’s use of improper use of, and disregarding of, manufacturer and industry common repair standards, [and] State Farm’s bad faith and unfair claims practice issues.” [Doc. 63-2 at 4]. Defendant moves to exclude “the opinions and conclusions contained in Mr. Castillo’s expert report.” [Doc. 63 at 2].1

1 In its Motion to Exclude, State Farm refers to the Practice Standards of Judge Philip A. Brimmer. [Doc. 63 at 1]. Judge Brimmer is not, nor has he ever been, the presiding judge on this action. This Court’s Civil Practice Standards state that all motions under Rule 702 “shall . . . specify, with particularity, the opinion(s) that the moving party seeks to exclude and the specific ground(s) on which each opinion is challenged, e.g., relevancy, 1. Qualifications State Farm’s first argument is that Mr. Castillo “does not demonstrate the requisite familiarity with the standards of the industry to qualify as an ‘insurance industry standard expert.” [Id. at 4 (emphasis omitted)]. While framed as an attack on Mr. Castillo’s

qualifications, State Farm does not contend that Mr. Castillo is unqualified based on his “knowledge, skill, experience, training, or education.” Fed. R. Evid. 702. Rather, State Farm relies on Mr. Castillo’s deposition testimony from a different case to argue that Mr. Castillo lacks familiarity with insurance industry standards. [Doc. 63 at 4]. State Farm cites no legal authority demonstrating that the Court may properly consider Mr. Castillo’s deposition testimony from a different case in assessing his qualifications here. See [id.]. In any event, the Court is not persuaded that Mr. Castillo’s extraneous deposition testimony provides a basis for exclusion. State Farm’s argument asks the Court to reflexively adopt State Farm’s subjective belief that Mr. Castillo’s knowledge of industry standards is inadequate—and fails to meet some unknown

standard set by State Farm itself—without any objective or legal basis to support its position. For example, State Farm suggests that Mr. Castillo is unqualified because he could not describe, in his deposition in another case, “what constitutes a valid and complete claim file according to the Colorado Division of Insurance.” [Doc. 63-4 at 38:20– 23; Doc. 63 at 4]. Accepting State Farm’s argument that this renders Mr. Castillo unqualified requires the Court to accept that an insurance industry expert must be able to articulate the Colorado Division of Insurance’s specific definition of “valid and complete

sufficiency, or methodology.” NYW Civ. Practice Standard § 7.1C(b).
