Civil rights: public records; disclosure of certain information without a warrant; prohibit. Creates new act.

HB 4858 would prohibit Michigan state and local government entities from sharing personal information (like names, addresses, Social Security numbers, or criminal history) with anyone seeking it for enforcing federal immigration law, unless a court-issued warrant is presented. Government agencies must verify if a request is for immigration enforcement and deny disclosure without a warrant. The bill requires agencies to report annual requests related to immigration enforcement to the attorney general and legislature. It directly affects local law enforcement, courts, and other government offices that handle public records, as well as federal immigration authorities seeking such data.
