Judge tosses DOJ suit on sanctuary laws
What happened
A federal judge in Colorado dismissed the Justice Department’s challenge to state and Denver 'sanctuary' policies, ruling the federal government cannot force local agencies to assist in federal immigration enforcement. The decision preserves local variation in cooperation and could keep county‑level policies important to detainee location, notice, and records access. The ruling was reported across regional outlets this week. (montrosepress.com)
Why it matters
U.S. District Judge Gordon P. Gallagher granted motions to dismiss the Justice Department’s case on March 31, 2026. (denvergov.org) The complaint was filed May 2, 2025 and named Governor Jared Polis, Colorado Attorney General Philip Weiser, Denver Mayor Mike Johnston and Denver Sheriff Elias Diggins as defendants while challenging four Colorado statutes and two Denver measures. (iptp-production.s3.amazonaws.com) At the pleading stage the United States argued the state and local measures were preempted by the Constitution’s Supremacy Clause — the principle that federal law displaces conflicting state or local law — and relied on federal statutes governing information sharing with immigration authorities. (denvergov.org) Judge Gallagher’s opinion maps to the anti‑commandeering line of cases deriving from the Tenth Amendment, explaining that federal law can invite or contract for local assistance but does not permit the federal government to force states or cities to operate or fund federal regulatory programs. (coloradopolitics.com) (supreme.justia.com) Operationally the order leaves in place the specific local controls the complaint targeted — for example, the Denver ordinance that restricts ICE from entering secure jail areas without a judicial warrant and the state provisions that limit use of local resources for federal immigration enforcement. (9news.com) (denvergov.org) Gallagher’s dismissal tracks rulings in other districts where judges rejected similar Justice Department claims — most notably the July 25, 2025 dismissal in the Illinois/Chicago case and a November 2025 dismissal in New York — signaling a recent pattern at the district‑court level on challenges to sanctuary‑style policies.
