The Anti-Sanctuary Act prohibits state and local government entities from adopting sanctuary policies that impede the enforcement of federal immigration law. It requires law enforcement agencies to support the enforcement of federal immigration law and allows for the exchange of information between law enforcement agencies and federal immigration agencies. The bill establishes enforcement mechanisms, allowing the attorney general to file suit against local governmental entities or law enforcement agencies for violations of the act. The bill takes effect on January 1, 2025. The fiscal impact of the bill is indeterminable, as it depends on the number of enforcement actions brought under the bill and the corresponding personnel and litigation costs associated with each action. The Department of Justice estimates that a small number of enforcement actions may be absorbed by existing staffing levels and litigation budget, but a larger number of enforcement actions would require additional resources.
