SUMMARY April 9, 2026

2026COA27

No. 25CA0175, Douglas County v. Colorado — Government — State and Local Involvement in Immigration Detention; Constitutional Law — Colorado Constitution — Article XIV — Intergovernmental Relationships — Article V — Revival, Amendment, or Extension

A division of the court of appeals addresses, for the first time

in a reported case, whether H.B. 23-1100 — which prohibits

counties and political subdivisions from entering into immigration

detention agreements with the federal government or private

entities — violates a county’s right to contract with the federal

government, as protected by article XIV, section 18 of the Colorado

Constitution. Similarly, this is the first reported case addressing

whether H.B. 23-1100 violates article V, section 24 of the Colorado

Constitution, which prohibits the amendment of statutes by

reference to their title only. The division concludes that H.B. 23-

1100 and the resulting statutes do not violate article XIV, section 18 or article V, section 24 of the Colorado Constitution, and the

district court did not err by dismissing Douglas County’s claims for

lack of standing. COLORADO COURT OF APPEALS 2026COA27

Court of Appeals No. 25CA0175 City and County of Denver District Court No. 24CV31125 Honorable David H. Goldberg, Judge

Douglas County, Colorado acting through the Board of County Commissioners of Douglas County Colorado, in their elected and official capacity, and Douglas County Sheriff,

Plaintiffs-Appellants,

v.

State of Colorado, by and through Jared S. Polis, in his official capacity as Governor of Colorado,

Defendant-Appellee.

JUDGMENT AFFIRMED

Division IV Opinion by JUDGE SCHUTZ Freyre and Brown, JJ., concur

Announced April 9, 2026

Jeffrey A. Garcia, County Attorney, Andrew C. Steers, Deputy County Attorney, Castle Rock, Colorado, for Plaintiffs-Appellants

Philip J. Weiser, Attorney General, Kyle M. Holter, Assistant Attorney General, Joseph G. Michaels, Assistant Solicitor General, Talia Kraemer, Assistant Solicitor General, Denver, Colorado, for Defendant-Appellee ¶1 Plaintiffs, Douglas County, acting through its Board of County

Commissioners, and the Douglas County Sheriff (collectively,

County), appeal the district court’s order granting the motion of

defendant, the State of Colorado, acting through Governor Jared S.

Polis, to dismiss on the grounds that the County suffered no injury

to a legally protected interest and therefore lacked standing to bring

its claims. We affirm the district court’s judgment.

I. Background and Procedural History

A. Legislative Overview

¶2 In 2019, the General Assembly enacted House Bill 19-1124

(H.B. 19-1124), which created article 76.6 of title 24 of the Colorado

Revised Statutes. See Ch. 299, sec. 2, 2019 Colo. Sess. Laws 2760-

62. The law declares that “[r]equests for civil immigration detainers

. . . are not warrants under Colorado law” and are not “reviewed,

approved, or signed by a judge as required by Colorado law,” so the

continued detention of an inmate under such requests beyond

when they would otherwise be released constitutes an

unconstitutional “warrantless arrest.” § 24-76.6-102(1)(b), C.R.S.

2025. Accordingly, the law mandates that state law enforcement

officers “shall not arrest or detain an individual on the basis of a

1 civil immigration detainer.” § 24-76.6-102(2)(a). The law also

prohibits probation officers and employees from providing personal

information about individuals to federal immigration authorities.

§ 24-76.6-103(1)(a), C.R.S. 2025.

¶3 In 2024, while this matter was being litigated in the district

court, a division of this court concluded that H.B. 19-1124’s

prohibitions on Colorado law enforcement arresting and detaining

individuals based solely on civil immigration detainers prevailed

over a county sheriff’s general grant of authority under Colorado

law. Nash v. Mikesell, 2024 COA 68, ¶¶ 44-45 (citing § 30-10-516,

C.R.S. 2025); see § 30-10-516 (“It is the duty of the sheriffs,

undersheriffs, and deputies to keep and preserve the peace in their

respective counties, and to quiet and suppress all affrays, riots, and

unlawful assemblies and insurrections.”). The division in Mikesell

also concluded that federal law does not require a state to comply

with immigration detainer requests and, therefore, federal law did

not preempt H.B. 19-1124. Id. at ¶ 34 (citing 8 U.S.C. § 1357(g)(1));

see 8 U.S.C. § 1357(g)(1) (The United States “Attorney General may

enter into a written agreement with . . . any political subdivision of

a State . . . to perform a function of an immigration officer in

2 relation to the investigation, apprehension, or detention of aliens in

the United States . . . to the extent consistent with State and local

law.”).

¶4 Following up on H.B. 19-1124, in 2023, the General Assembly

enacted House Bill 23-1100 (H.B. 23-1100), which created article

76.7 of title 24 of the Colorado Revised Statutes. See Ch. 413, sec.

2, 2023 Colo. Sess. Laws 2449. As relevant to this case,

section 24-76.7-102(1), C.R.S. 2025, provides that state

governmental entities may not

(a) Enter into an agreement of any kind for the detention of individuals in an immigration detention[1] facility that is owned, managed, or

1 In its briefing on appeal, the County often transposes the terms

“detainer” and “detention.” H.B. 19-1124, as codified in title 24, article 76.6, addresses civil immigration detainer requests. See § 24-76.6-101(1), C.R.S. 2025 (‘“Civil immigration detainer’ means a request for federal immigration enforcement to law enforcement officers to arrest or detain an individual or to maintain custody of an individual beyond the time when the individual is eligible for release from custody, including a request for law enforcement agency action, warrant for arrest of alien, order to detain or release alien, or warrant of removal or deportation on a form promulgated by federal immigration enforcement.”). H.B. 23- 1100, as codified in title 24, article 76.7, addresses civil immigration detention agreements. See § 24-76.7-101(2), C.R.S. 2025 (‘“Immigration detention agreement’ means any contract, including but not limited to an intergovernmental service agreement, or portion thereof for payment to a governmental entity to detain individuals for federal civil immigration purposes.”).
