Case Overview

The Trump administration sued Illinois over a state law signed on Dec. 9 that purports to subject federal immigration officers to civil liability and punitive damages while acting under federal authority and includes a ban on “civil arrests” on state courthouse grounds and within 1,000 feet of the courthouse.


The Application

History

Illinois's law directly conflicts with federal immigration authority by subjecting federal officers to civil liability for actions under federal law and prohibiting federal law enforcement near courthouses: creating legal and practical obstacles to federal immigration operations.

The Conclusion

Case filed Dec. 22, 2025, remains active. The Trump administration contests the Illinois law as facially unconstitutional interference with exclusive federal immigration enforcement authority.
