State government: federal immigration policy enforcement.

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 alien presently in the custody of that agency, for the purpose of arresting and removing the alien. Existing federal law provides that the detainer is a request that the agency advise the department, prior to release of the alien, in order for the department to arrange to assume custody in situations when gaining immediate physical custody is either impracticable or impossible. Existing law authorizes a law enforcement official, as defined, to cooperate with federal immigration officials by detaining an individual on the basis of a United States Immigration and Customs Enforcement hold after that individual becomes eligible for release from custody, if at the time that the individual becomes eligible for release from custody, certain conditions are met, including, among other things, that the individual has been convicted of specified crimes. This bill would prohibit a law enforcement official from cooperating with federal immigration officials by providing information about a juvenile held in a juvenile detention facility, or by detaining a juvenile on the basis of an immigration hold after that juvenile becomes eligible for release from custody, unless not cooperating would violate federal law and the juvenile has been convicted of specified crimes.
