The proposed bill, known as 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 peace officers or local officials from communicating or cooperating with federal officials regarding the immigration status of individuals. The bill defines a "local unit of government" to include counties, cities, villages, townships, and related bodies. It mandates that any existing laws that conflict with this act must be brought into compliance within 60 days of the act's effective date, and any conflicting laws will be deemed void and unenforceable.

Furthermore, the bill provides mechanisms for enforcement, allowing residents to take legal action against local governments that violate the act, and empowers the attorney general to investigate complaints and enforce compliance. If a violation is confirmed, the court can issue injunctions, mandate amendments or repeals of conflicting laws, and award damages to the complainant. Additionally, elected or appointed officials who knowingly violate the act may face civil fines ranging from $2,500 to $7,500, which are separate from other legal penalties.
