ICAP is defending Washtenaw County Sheriff Alyshia Dyer and the Washtenaw County Sheriff’s Office against a lawsuit that challenges their policy of limiting local involvement in federal immigration enforcement. The Sheriff’s policy prohibits employees from using Sheriff’s Office resources to enforce immigration law or assist in immigration-related matters, such as by asking about immigration status in performing official duties or detaining individuals based solely on requests from ICE and without a judicial warrant. The federal government claims that the Sheriff’s policy is preempted by federal law and violates principles of intergovernmental immunity. This case is only one in a series of lawsuits brought by the federal government to compel States and localities to support its immigration agenda.
