SB 509 prohibits Michigan government entities (like police departments, courts, or DMVs) from sharing personal information - including addresses, IDs, or criminal history - with federal immigration authorities unless a court-issued warrant is presented. It requires agencies to verify if requests are for immigration enforcement and deny such requests without a warrant. Agencies must also report annual data on these requests to state officials by March 31 each year. The law aims to prevent local government data from being used in federal immigration actions without judicial oversight.
