"New Jersey Laken Riley Act;" establishes law enforcement procedures for arrests of aliens unlawfully present in the U.S. charged with certain crimes.

The New Jersey Laken Riley Act requires law enforcement to check the immigration status of non-citizens arrested for specific serious crimes - including violent offenses, certain traffic violations causing injury, or federal "aggravated felonies." If confirmed as unlawfully present, these individuals face a legal presumption of pretrial detention, overriding the state's bail reform law. The bill mandates compliance with federal immigration detainer requests and repeals a prior law prohibiting local jails from holding immigrants for federal authorities. It also rescinds New Jersey's "Immigrant Trust Directive," aligning state procedures with federal immigration enforcement priorities.
