Bill > HB4470

This bill amends the Michigan penal code to modify provisions related to unauthorized entry into key facilities, expanding the definition of such facilities to include the portions of the Mackinac Bridge not open to or intended for public use. The bill redefines key facilities as specific types of industrial, utility, transportation, and manufacturing sites that are completely enclosed by a physical barrier and posted with conspicuous signage, and adds detailed requirements for posting signs with minimum letter heights and spacing. The legislation maintains the existing criminal penalty of up to 4 years imprisonment or a $2,500 fine for unauthorized entry, and includes a new provision clarifying that the presence of an open barrier during normal business hours does not constitute a legal defense against prosecution. The bill preserves protections for lawful assembly and peaceful petitions, ensuring that the restrictions do not interfere with legitimate public demonstrations or labor dispute activities. Key terms like "key facility" are broadly defined to include facilities such as chemical plants, power stations, water treatment facilities, transportation hubs, and other critical infrastructure sites.
