The proposed bill, known as the "county law enforcement protection act," aims to prevent counties 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. It defines "county" to include various county entities and officials, and establishes that any conflicting local laws are void and unenforceable. Counties are required to bring any existing non-compliant laws into alignment with this act within 60 days of its effective date.

Furthermore, the bill provides mechanisms for enforcement, allowing residents to take legal action against counties that violate the act, either by filing a complaint with the attorney general or bringing a case in circuit court. The attorney general is also empowered to investigate complaints and enforce compliance. If a court finds that a county's law violates the act, it can issue an injunction, mandate amendments or repeals, and award damages to the complainant. Conversely, if a county prevails in a legal challenge, it may be awarded costs and attorney fees.
