Islip: No Sanctuary Law; ICE Detainers Not Honored
Few RestrictionsPeople ex rel. Wells v DeMarco, 168 AD3d 31 (2d Dept 2018)
we conclude that New York state and local law enforcement officers are not authorized by New York law to effectuate arrests for civil law immigration violations. ... Since the administrative warrant issued by ICE was not issued by a judge or a court, the Sheriff lacked New York statutory authority to effectuate an arrest pursuant to the ICE warrant.
