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.

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

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

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.”).

operated, in whole or in part, by a private entity;

(b) Sell any public or government-owned property or building for the purpose of establishing an immigration detention facility that is or will be owned, managed, or operated, in whole or in part, by a private entity; [or]

(c) Pay, reimburse, subsidize, or defray in any way any costs related to the sale, purchase, construction, development, ownership, management, or operation of an immigration detention facility that is or will be owned, managed, or operated, in whole or in part, by a private entity[.]

§ 24-76.7-102(1).

¶5 The law also requires governmental entities to terminate any existing immigration detention contracts by January 1, 2024, and mandates that, as of the same date, “a governmental entity shall not enter into or renew an immigration detention agreement.” § 24- 76.7-103(1), C.R.S. 2025.

B. The County’s Lawsuit

¶6 In 2024 the County2 filed a complaint in district court asserting claims that H.B. 19-1124 and H.B. 23-1100 violate (1) the

2 El Paso, Mesa, Rio Blanco, Elbert, and Garfield Counties and their

respective sheriffs were named as plaintiffs in the district court; however, only Douglas County and its sheriff are pursuing this appeal.
