Sanctuary city policies are state or local government decisions to limit cooperation with federal immigration enforcement, typically by refusing to use local police or jail resources to detain immigrants for federal immigration authorities or restricting information sharing with ICE.
Sanctuary policies don't prevent federal agents from enforcing immigration law—ICE can still conduct raids, make arrests, and seek deportations. They prevent local officials from becoming force multipliers for federal enforcement. A police officer in a sanctuary jurisdiction won't stop someone for a traffic violation and detain them while ICE decides whether to take custody. Local jails won't hold inmates longer than their sentences to give ICE time to arrange deportation.
This is constitutionally permissible: the Tenth Amendment reserves powers to the states, and states cannot be commandeered to enforce federal law. Congress can't force state officers to enforce federal immigration law. However, Congress can withhold federal funds from sanctuary jurisdictions as a condition of accepting federal grants. Courts have upheld some fund-withholding schemes but struck down others as coercive beyond Congress's spending power.
Sanctuary policies represent federalism in action: states deciding not to participate in federal enforcement. They shape whether local police become immigration agents and whether immigrants trust local law enforcement.
People think sanctuary cities violate federal law or harbor criminals. They generally decline to use local resources for federal immigration enforcement, which is constitutional. Sanctuary status doesn't prevent federal enforcement, only local assistance.
