Court Dismisses Justice Department Lawsuit Against Colorado and Denver Sanctuary Laws
On March 31 a federal judge threw out the Justice Department’s lawsuit alleging that Colorado and the City of Denver violated the Supremacy Clause by limiting cooperation with federal immigration enforcement. Judge Gordon P. Gallagher cited the Supreme Court’s 1997 anti-commandeering precedent, ruling that the federal government cannot force states or cities to use local resources to implement federal immigration programs. The decision allows four state statutes and two Denver ordinances—covering information-sharing, detainer requests, and non-cooperation policies—to stand.

For corporate mobility teams, the ruling means that local “sanctuary” protections remain intact, simplifying compliance for employees who fear ICE interactions when obtaining driver’s licenses or interacting with local police. The Justice Department has filed similar suits in Los Angeles, New York, and Minnesota; observers expect those courts to rely on the Colorado decision. A circuit split could ultimately return the question to the Supreme Court, but for now employers operating in sanctuary jurisdictions can continue current onboarding and duty-of-care protocols without additional federal oversight. Companies should still educate foreign national staff on varying local enforcement climates, update mobility policies to reflect safe-harbor jurisdictions, and coordinate with counsel on incident-response plans in non-sanctuary states.
