Idaho Bans Sanctuary Cities Statewide

Idaho Code 18-7106 prohibits local governments, including counties, cities, and other political subdivisions, from enacting any ordinance, resolution, rule, or policy that limits or restricts compliance with federal immigration law or cooperation with federal immigration authorities. Adopted as House Bill 463 in 2014, the law bars sanctuary city status by requiring local agencies and officials to honor federal immigration detainers and information-sharing requests consistent with federal statutes such as 8 U.S.C. 1373 and 1644. Local law enforcement may inquire about immigration status during lawful contact and must share information with U.S. Immigration and Customs Enforcement. Cities like Boise, Pocatello, and Idaho Falls cannot adopt policies refusing to honor ICE detainers or restricting officer cooperation. The statute does not require local police to enforce civil immigration law independently but ensures no policy obstructs federal cooperation.

Local ordinances or policies conflicting with Idaho Code 18-7106 are void. Officials adopting noncompliant policies may face legal challenges and loss of certain state funding eligibility.
