Congress finds the following:
(1)
Existing Federal law authorizes any authorized immigration officer to issue an immigration detainer that serves to advise another law enforcement agency that the Federal department seeks custody of an undocumented immigrant presently in the custody of that agency, for the purpose of arresting and removing the undocumented immigrant.
(2)
Unlike criminal detainers, which are supported by a warrant and require probable cause, there is no requirement for a warrant and no established standard of proof, such as reasonable suspicion or probable cause, for issuing an ICE detainer request. Immigration detainers have erroneously been placed on United States citizens, as well as immigrants who are not deportable.
(3)
Galarza v. Szalczyk, U.S. Court of Appeals for the Third Circuit ruled in March 2014 that States and counties are not required to keep undocumented immigrants in jail on immigration detainers; and in April 2014, Miranda-Olivares v. Clackamas County, the U.S. District Court in Portland, Oregon, found that county governments would be exposed to civil rights lawsuits for honoring detainers not issued in compliance with Fourth Amendment protections, including a showing of probable cause.
