No. 24CA0079, Mosley v. Daves — Civil Action for Deprivation of Rights; Constitutional Law — Fourth Amendment — Searches and Seizures — Warrantless Search; Civil Jury Instructions — Affirmative Defenses

In a case of first impression, a division of the court of appeals holds that legal justification for a warrantless search is an affirmative defense that the defendant must prove in a civil action under section 13-21-131, C.R.S. 2025. The division also holds that the trial court properly limited expert testimony and properly excluded evidence of a gun found during the protective sweep. Finally, the division holds that the trial court’s award of attorney fees and costs to the plaintiff was reasonable, and it remands the case for the trial court to determine the plaintiff’s reasonable appellate attorney fees.

Division IV

Opinion by JUDGE MEIRINK

Gomez and Bernard*, JJ., concur

Announced October 2, 2025

Frank Law Office LLC, Adam Frank, Denver, Colorado, for Plaintiff-Appellee

Peter A. Schulte, City Attorney, Gillian Fahlsing, Assistant City Attorney, Gregory R. Bueno, Assistant City Attorney, Aurora, Colorado, for Defendant- Appellant

*Sitting by assignment of the Chief Justice under provisions of Colo. Const. art. VI, § 5(3), and § 24-51-1105, C.R.S. 2025.

¶1 After defendant, Aurora Police Department Officer Brendan Daves, searched the vehicle of plaintiff, Christopher Mosley, without a warrant, Mosley filed a lawsuit under section 13-21-131, C.R.S. 2025, asserting a violation of his constitutional rights. The jury returned a verdict in Mosley’s favor, and the trial court granted Mosley’s motion for attorney fees and costs and entered judgment accordingly.

¶2 As an issue of first impression, Daves argues that the trial court erred by instructing the jury that, in Mosley’s section 13-21- 131 action challenging a warrantless search, Daves had the burden of proving the affirmative defense that the search was reasonable. We disagree with Daves and conclude that the trial court properly instructed the jury that Daves had the burden of proving that affirmative defense.

¶3 We therefore affirm the judgment and remand the case to the trial court to determine Mosley’s reasonable appellate attorney fees and costs.

I. Factual Background

¶4 In April 2021, Daves pulled Mosley over because the vehicle Mosley was driving did not have a license plate. Daves ordered

Mosley to exit the vehicle and patted him down. Daves did not find a weapon during the pat-down. Daves ordered Mosley to sit on the bumper of the police vehicle while Daves ran a brief search of his driver’s license and continued to observe his demeanor. Daves testified that, after running the search, he was going to let Mosley go and “write him a summons or issue him a warning” for the license plate violation. Before doing so, however, Daves searched Mosley’s vehicle. Daves did not have a warrant to conduct the search.

¶5 Mosley sued Daves under section 13-21-131, alleging that Daves’s warrantless search violated article II, section 7, of the Colorado Constitution, which prohibits unreasonable searches and seizures.

¶6 Following the jury’s verdict in favor of Mosley, the court awarded Mosley attorney fees and costs as the prevailing party under section 13-21-131(3) and C.R.C.P. 54(b). Daves appeals.

II. Analysis

¶7 Daves contends that the trial court erred by (1) incorrectly stating the law in its jury instructions with respect to the Fourth Amendment, thereby impermissibly shifting the burden of proof to

him; (2) precluding Daves’s expert from testifying about how officers are trained to determine if there is reasonable suspicion to conduct a protective sweep; (3) excluding evidence obtained from Daves’s protective sweep of Mosley’s vehicle; and (4) awarding Mosley $130,987 in attorney fees and $3,405 in costs. We disagree with each contention.

A. The Trial Court Properly Instructed the Jury that the Reasonableness of a Warrantless Search is an Affirmative Defense

¶8 Daves first contends that the trial court erroneously instructed the jury that, once Mosley met his burden of proving that Daves searched his vehicle without a warrant, the burden shifted to Daves to prove, as an affirmative defense, that the search was reasonable. We disagree.

1. Additional Applicable Facts

¶9 At trial, Daves argued that he had a reasonable suspicion to expand Mosley’s traffic stop and that Daves’s protective sweep of the vehicle was legal under the circumstances. The court ruled that Daves’s proffered legal justification was an affirmative defense and thus Daves had the burden of proving the elements of that defense.

¶ 10 Both Mosley and Daves submitted proposed jury instructions. The court reviewed them, provided the parties with a preliminary draft, and held a jury instruction conference. The final jury instructions provided that Daves’s claim of legal justification was an affirmative defense that he had to prove by a preponderance of the evidence. Although Daves proposed an instruction that placed the burden of proof on Mosley and argued during the instruction conference that the burden should be Mosley’s, Daves did not object to the final draft of the instructions.

¶ 11 In relevant part, the trial court gave the following jury instructions:

Instruction No. 1

The plaintiff Christopher Mosley claims that on April 25, 2021, the defendant Brendan Daves, a police officer, violated Mr. Mosley’s constitutional right to be free from unreasonable searches, by unjustifiably searching Mr. Mosley’s automobile without a warrant.

The defendant, Brendan Daves, does not dispute that he is a police officer, nor does he dispute that he searched plaintiff’s vehicle without a warrant. However, as an affirmative defense, defendant asserts that he was justified in conducting a protective sweep of

the vehicle, an exception to the warrant requirement.

....

Instruction No. 7

For the plaintiff, Christopher Mosley, to recover from the defendant, Brendan Daves, on his claim of violation of a constitutional right, you must find that all of the following have been proved by a preponderance of the evidence:

1. Defendant Brendan Daves is a “Peace Officer.”

2. On or about April 25, 2021, Defendant Brendan Daves, acting in his capacity as a Peace Officer, searched Plaintiff Christopher Mosley’s vehicle.

3. At the time of the search Defendant Brendan Daves did not have a warrant for such search.

If you find that any one or more of these three statements has not been proved, then your verdict must be for the defendant.

On the other hand, if you find that all of these three statements have been proved, then you must consider the affirmative defense of an exception to the constitutional warrant requirement allowing for a “protective sweep” of a vehicle.

If you find that this affirmative defense has been proved by a preponderance of the

evidence, then your verdict must be for the defendant.

However, if you find that this affirmative defense has not been proved, then your verdict must be for the plaintiff.

The court also provided jury instructions regarding the warrant requirement and the protective sweep exception to the warrant requirement.
