District attorneys and public defenders filed a lawsuit Monday April 29, 2019 to prohibit Immigration and Customs Enforcement (ICE) agents from entering into state courthouses to enforce detainers.
The United States Department of Homeland Security allows ICE the ability to issue a detainer, which is an immigration hold request to federal, state, and local law enforcement agencies who currently have an alien arrested on criminal charges in their custody. The detainer asks law enforcement agencies to notify ICE before releasing the alien, and to additionally detain the individual up to 48 hours in order for ICE to determine whether or not they wish to take the alien into federal custody. ICE uses detainers for those aliens they have probable cause to believe should be deported from the U.S.
