The proposed bill, titled the "local government sanctuary policy prohibition act," aims to prevent local units of government in Michigan from enacting or enforcing any laws, ordinances, policies, or rules that restrict local officials from communicating or cooperating with federal authorities regarding the immigration status of individuals. It defines a "local unit of government" to include cities, villages, townships, and their respective boards and officials. The bill mandates that any existing laws that conflict with this act must be amended or repealed within 60 days of its effective date.

Furthermore, the bill establishes enforcement mechanisms, allowing residents to take legal action against local governments that violate the act, and empowers the attorney general to investigate complaints and initiate enforcement actions. If a court finds that a local law violates the act, it can issue an injunction, require amendments or repeals, and award damages and attorney fees to the complainant. Conversely, if a court rules in favor of the local government, it may award costs and attorney fees to the prevailing party.
