O R D E R

Before the Court is Plaintiffs’ Motion to Compel [Doc. No. 87]. Defendant Sheriff Cory Rink has responded [Doc. No. 106] and Plaintiffs have replied [Doc. No. 111]. The matter is fully briefed and ready for determination. I. Legal Standard Under Rule 26(b), district courts have discretion in resolving discovery disputes. Murphy v. Deloitte & Touche Grp. Ins. Plan, 619 F.3d 1151, 1164 (10th Cir. 2010). But courts are not without instruction. Civil litigants “may obtain discovery regarding any nonprivileged matter that is relevant to any party’s claim or defense and proportional to the needs of the case.” Fed. R. Civ. P. 26(b)(1). Accordingly, the scope of discovery is governed by both relevance and proportionality. See, e.g., In re Bard IVC Filters Prod. Liab. Litig., 317 F.R.D. 562, 564 (D. Ariz. 2016) (“Relevancy alone is no longer sufficient—discovery must also be proportional to the needs of the case.”). In permitting or denying discovery requests, courts are instructed to consider “the importance of the issues at stake in the action, the amount in controversy, the parties’ relative access

to relevant information, the parties’ resources, the importance of the discovery in resolving the issues, and whether the burden or expense of the proposed discovery outweighs its likely benefit.” Fed. R. Civ. P. 26(b)(1). Relevance “encompass[es] any matter that bears on, or that reasonably could lead to other matter that could bear on’ any party’s claim or defense.” United States ex rel. Shamesh v. CA, Inc., 314 F.R.D. 1, 8 (D.D.C. 2016) (quoting Oppenheimer Fund, Inc. v.

Sanders, 437 U.S. 340, 351 (1978)). “When the discovery sought appears relevant, the party resisting the discovery has the burden to establish the lack of relevance by demonstrating that the requested discovery (1) does not come within the scope of relevance as defined under [Rule] 26(b)(1), or (2) is of such marginal relevance that the potential harm occasioned by discovery would outweigh the ordinary presumption in favor

of broad disclosure.” Johnson v. Kraft Foods N. Am., Inc., 238 F.R.D. 648, 653 (D. Kan. 2006). But “when the request is overly broad on its face or when relevancy is not readily apparent, the party seeking the discovery has the burden to show the relevancy of the request.” Id. The proportionality analysis considers “the importance of the issues at stake in the

action, the amount in controversy, the parties’ relative access to relevant information, the parties’ resources, the importance of the discovery in resolving the issues, and whether the burden or expense of the proposed discovery outweighs its likely benefit.” Fed. R. Civ. P. 26(b)(1). Information “need not be admissible in evidence to be discoverable.” Id. II. Background This action arises from a deputy-involved shooting on September 15, 2022, that

resulted in the death of Plaintiffs’ son. As alleged, the shooting occurred at Plaintiffs’ home when Garfield County Sergeant Brant Bishop responded to a call that Plaintiffs’ son was experiencing a mental health crisis. Plaintiffs assert various claims under 42 U.S.C. § 1983 against Garfield County Sheriff Cory Rink, in his official capacity, and Sgt. Bishop, including claims premised on Monell liability and for a failure to train and supervise. Plaintiffs allege, among other things, that Sgt. Bishop was not properly trained on crisis

intervention, de-escalation, or responding to individuals experiencing a mental health crisis. Pet. [Doc. No. 1] ¶ 31, 46–103. III. Discussion The parties’ briefing reflects commendable efforts to narrow the scope of the discovery dispute before the Court. As such, Plaintiffs’ Motion to Compel seeks an order

compelling production of the following:1 1. “The file that indicates when policies and procedures were actually signed by the Sheriff and enacted just a ‘couple weeks’ prior to [Major] Layton deposition (in February of 2026).

2. The policies and procedures provided to Sgt. Reim by email, in native format;

3. The final version of the policies and procedures on [Major] Layton’s computer in original format; and

4. Production of [Deputy] Hunter and [Deputy] Prince digital drives to a third party forensic data company.”

1 For clarity, the Court refers to these numerical items as “Requests 1–4” for purposes of this Order. Mot. [Doc. No. 87] at 9.2 Plaintiffs contend that although Defendants have produced a Use of Force Policy

that they state was in effect at the time of the shooting, deposition testimony from numerous officers reflects uncertainty and inconsistency regarding which policies were officially in effect, when those policies became effective, and to whom they were disseminated. Compounding the confusion, Sheriff Rink testified that the relevant Mental Health Policy came into effect prior to the incident and Sgt. Bishop would have signed that he received a copy, but defense counsel later informed Plaintiffs that no such acknowledgment exists for

Sgt. Bishop. Bishop Dep. [Doc. No. 87-1]; Counsel Email [Doc. No. 87-3]. Thus, according to Plaintiffs, “how and when this policy actually came into force and if it was actually disseminated is very much at issue.” Id. at 5. Sheriff Rink objects to production on relevancy and proportionality grounds. Resp. [Doc. No. 106] at 7–9. The substance of his objection, however, amounts largely to

challenging Plaintiffs’ characterization of the dispute rather than establishing why the requested materials are irrelevant or unduly burdensome. He does not meaningfully dispute that the requested materials bear on what policies were in effect at the time of the incident, when those policies were adopted, or whether they were disseminated to the involved officers. Nor does he explain how production of these files—many of which the

2 Sheriff Rink raises no argument that these documents are outside the scope of Plaintiffs’ requests for production, and the Court is satisfied that they are encompassed by those requests. See Mot. [Doc. No. 87] at 2–4 (quoting the relevant requests for production). officers testified they still have in their offices or their possession, see [Doc. No. 87-6]— are too burdensome or expensive to produce. Resp. [Doc. No. 106] at 9.

Requests 1–3. Plaintiffs seek native digital versions of the policies and procedures that are in possession of certain officers as well as records of their approval—specifically, the source file on Major Layton’s computer, the file emailed to Sgt. Reim, and the Sheriff’s signed approval document. The policies and procedures in effect at the time of the incident and whether those policies were disseminated are relevant to Plaintiffs’ claims under a Monell theory and failure to train and supervise. See Thao v. Grady Cnty. Crim. J. Auth.,

159 F.4th 1214 (10th Cir. 2025); Zuchel v. City and Cnty.
