This legislation aims to prevent the establishment or operation of immigration detention facilities in a specific Maryland county. It explicitly prohibits the Department of Homeland Security and its components, including U.S. Immigration and Customs Enforcement (ICE) , from establishing, operating, expanding, or reopening any immigration detention or holding facility in Washington County, Maryland. Furthermore, the bill mandates that no federal funds appropriated to these agencies may be obligated or expended for any such purpose within the designated county. To ensure enforcement, the legislation grants legal standing to residents of Washington County, the county government, Members of Congress, and the State of Maryland to bring actions in federal court. Courts are empowered to provide declaratory and injunctive relief to prevent any activities violating this prohibition, reflecting concerns about the impact of such facilities on local communities and the conditions within immigration detention.
