Law enforcement: other; immigration enforcement at certain locations; prohibit in certain circumstances. Creates new act.

HB 4859 prohibits law enforcement officers from conducting immigration enforcement actions (like arrests, interviews, or searches) in specific sensitive locations, including schools, places of worship, hospitals, courthouses, and facilities serving vulnerable populations. The bill allows exceptions only if a court orders entry or if an immediate threat to public safety requires action. It directly affects law enforcement officers operating in Michigan and individuals present at these locations, such as students, patients, and worshippers. The law creates clear boundaries for immigration enforcement to protect access to essential services and community spaces.
