United States v. State of Illinois — 7th Cir. (Oct 29, 2026)
The Seventh Circuit hears the federal government's challenge to sanctuary policies in Illinois, Cook County, and Chicago. These laws limit local assistance with civil immigration enforcement, including sharing release information and transferring people to immigration custody. An immigration detainer is a request for notice before release so federal authorities can arrange to take custody. The United States sued to block the policies, saying they obstruct federal enforcement. The district court dismissed the suit, treating the policies as a protected choice not to assist civil immigration enforcement. The federal government appealed. Preemption means valid federal law can override conflicting state or local law. Anticommandeering generally prevents Congress from making state and local officers administer a federal regulatory program. Intergovernmental immunity generally protects the federal government from state laws that directly regulate it or discriminate against it. Two disputed statutes, sections 1373 and 1644, protect exchanges of information regarding immigration status. Their reach and constitutional validity are contested here. Michael Talent will argue for the United States.
