Today, the U.S. Department of Justice filed suit against the State of New Jersey, New Jersey Governor Philip Murphy, and New Jersey Attorney General Gurbir Grewal. The lawsuit challenges New Jersey Attorney General Law Enforcement Directive 2018-6, which prohibits state officials from sharing information with U.S. Immigration and Customs Enforcement (ICE) related to the immigration status and release dates of individuals in their custody.

The directive also requires New Jersey law enforcement to “promptly notify a detained individual, in writing and in a language the individual can understand” if ICE files an immigration detainer request for the individual. According to the complaint filed today, on multiple occasions last year, New Jersey officials failed to provide information regarding the release dates of aliens who had been charged with or convicted of crimes. New Jersey’s decision to obstruct federal immigration enforcement by refusing to provide such information is unlawful under the Supremacy Clause of the U.S. Constitution.
