The Law · How the Case Works

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.
