This bill aims to strengthen the enforcement of immigration laws in Michigan by criminalizing the illegal entry and presence of aliens in the state. It establishes penalties for individuals who enter or attempt to enter Michigan at locations other than lawful ports of entry, with first-time offenders facing misdemeanor charges and subsequent violations escalating to felony charges. The bill also outlines specific circumstances under which individuals may have an affirmative defense against prosecution, such as being granted lawful presence by the federal government or being approved for certain federal programs. Additionally, it prohibits law enforcement from arresting individuals at schools, places of worship, or healthcare facilities under certain conditions.

Furthermore, the bill provides legal protections and indemnification for state and local officials, employees, and contractors involved in the enforcement of these immigration laws. It grants immunity from liability for actions taken in good faith while enforcing the provisions of the bill and outlines the process for reimbursement of legal expenses incurred during such enforcement. The legislation also stipulates that any civil actions related to these protections must be appealed directly to the state supreme court. The act is set to take effect 90 days after being enacted into law.
