This bill, named the "Justice for Victims of Sanctuary Cities Act of 2025," creates a new civil remedy for individuals who suffer harm due to crimes committed by aliens in jurisdictions with "sanctuary policies." It defines a sanctuary jurisdiction as any state or political subdivision that restricts its entities from sharing immigration status information or complying with lawful Department of Homeland Security (DHS) detainer requests or release notifications for aliens. An exception is made for policies protecting alien victims or witnesses of crimes. Under this Act, a private right of action is established, allowing victims of murder, rape, or certain felonies committed by an alien to sue a sanctuary jurisdiction for compensatory damages . This action can be brought if the jurisdiction failed to comply with a DHS detainer request or notification regarding the alien's release. To facilitate these lawsuits, states and political subdivisions that accept specific federal grants, such as certain public works or community development block grants, are required to waive immunity related to these sanctuary-related civil actions. Furthermore, the bill aims to encourage cooperation between federal and local law enforcement by providing liability protections . When a state or local entity complies with a DHS detainer, it is deemed to be acting as an agent of DHS. In legal proceedings challenging such compliance, the state or subdivision is not liable, and its officers are considered federal employees, with the United States being substituted as the defendant. This provision, however, does not grant immunity for knowingly violating an individual's civil or constitutional rights.
