SUMMARY October 2, 2025

2025COA80

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. COLORADO COURT OF APPEALS 2025COA80

Court of Appeals No. 24CA0079 Arapahoe County District Court No. 22CV31471 Honorable Elizabeth Beebe Volz, Judge

Christopher Mosley,

Plaintiff-Appellee,

v.

Brendan Daves,

Defendant-Appellant.

JUDGMENT AFFIRMED AND CASE REMANDED WITH DIRECTIONS

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

1 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

2 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.

3 ¶ 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

4 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.
