SUMMARY November 13, 2025

2025COA88

No. 24CA1046 Castillo v. STEM — Government — Colorado Governmental Immunity Act — Claire Davis School Safety Act; Justiciability — Mootness

As a matter of first impression, a division of the court of

appeals considers whether the Claire Davis School Safety Act, § 24-

10-106.3, C.R.S. 2025, requires a case to proceed to a jury trial

after the parties have completed full discovery, the defendant

deposits with the court the maximum amount of damages that the

plaintiffs could recover at trial, and the defendant agrees that the

sum may be released to the plaintiffs but does not admit liability.

The division concludes that in these circumstances, a district court

does not err by dismissing the case as moot. COLORADO COURT OF APPEALS 2025COA88

I. Background and Procedural History

A. School Violence

¶2 School shootings in the United States occur with alarming

repetition, terrorizing students, teachers, families, and

communities. Colorado has not escaped these tragedies. See Ch.

266, sec. 1(2), 2015 Colo. Sess. Laws 1035 (Between 1999 and

2015, there were “three separate incidents of school violence [in

Colorado] in which students [were] killed at their schools.”); Haylee

May, Colorado Already Has Measures in Place to Prevent School

Shootings, Where Are the Gaps?, Colo. Pub. Radio (Sept. 12, 2025),

https://perma.cc/Z4HX-NN66 (“Colorado has seen [twenty-five]

incidents of gunfire on school campuses since 2013 . . . .”).

1 The Castillos also named the Douglas County School District as a

defendant. However, the District and the Castillos settled their dispute, and the District is not a party to this appeal.

1 ¶3 In an effort to prevent school violence and to compensate

victims, while simultaneously protecting public and charter schools

from unlimited liability, the Colorado General Assembly passed the

Claire Davis School Safety Act (Act), § 24-10-106.3, C.R.S. 2025.

The General Assembly explained the Act’s multiple objectives as

follows:

(3) . . . [T]he General Assembly . . . declares the purposes of this [A]ct are:

(a) To recognize and state that there is a limited duty of reasonable care upon public schools, charter schools, and their employees to provide for student safety and to protect students and employees in their schools;

(b) To waive on a limited basis governmental immunity, thereby allowing for recovery of capped damages where that duty of reasonable care has been breached by a school district, charter school, or their employees; and

(c) To waive on a limited basis governmental immunity to ensure that there is a robust and effective discovery through the legal system of the causes of acts of school violence.

(4) It is the intent of the [G]eneral [A]ssembly in enacting this [A]ct to affirmatively recognize a statutory duty upon school districts, charter schools, and their employees to protect students, faculty, and staff from foreseeable harm caused by other persons. The [G]eneral [A]ssembly hereby declares that the purpose of recognizing that this duty exists under this

2 [A]ct is to create a tort remedy against school districts and charter schools in cases where a school district, charter school, or its employees knew or should have known of the danger that was presented and breached that duty of care.

(5) The [G]eneral [A]ssembly also further states that its intent in enacting the provisions in this [A]ct regarding discovery and settlement is to provide a remedy for plaintiffs affected by acts of school violence and to achieve robust and vigorous discovery of events leading to those incidents of school violence.

2015 Colo. Sess. Laws at 1036; see Stamp v. Vail Corp., 172 P.3d

437, 443 n.7 (Colo. 2007) (treating an uncodified legislative

declaration of purpose “as equal in authority” to a codified

declaration).

¶4 To achieve these objectives, the General Assembly created a

limited waiver of schools’ sovereign immunity to permit victims of

school violence to bring a claim for monetary damages, subject to

the limits of the Colorado Governmental Immunity Act (CGIA), see

§§ 24-10-101 to -120, C.R.S. 2025, and to engage in “vigorous

discovery” concerning the events leading to the school violence.

2015 Colo. Sess. Laws at 1036.

¶5 This case requires us to resolve whether, after the completion

of vigorous and full discovery, a defendant’s deposit of a plaintiff’s

3 maximum potential recovery in the court’s registry — with an

agreement that such funds should be delivered to the plaintiffs in

satisfaction of their claim, but without an admission of liability —

permits the court to dismiss a plaintiff’s claims as moot. We

conclude that it does and therefore affirm the district court’s

dismissal of the Castillos’ claims against STEM.

B. The 2019 Shooting

¶6 STEM is a publicly funded charter school. On May 7, 2019,

two STEM students obtained handguns, entered a classroom that

contained twenty-nine students — including eighteen-year-old

Kendrick Castillo2 — blocked the door, and started shooting. One

of the perpetrators fatally shot Kendrick when Kendrick rushed

forward to protect others in the classroom. Students then

restrained both perpetrators until police officers arrived.3

Kendrick’s selfless and heroic actions are credited with saving many

lives. He was murdered two weeks before his high school

graduation.

2 To avoid confusion with his parents, we refer to Kendrick by his

first name. We mean no disrespect in doing so. 3 Both perpetrators were subsequently convicted of first degree

murder.
