Illinois Court Allows DOJ Challenge to State Bivens and CASPA Laws
Illinois federal court denied state's motion to dismiss DOJ's lawsuit over Bivens and CASPA laws.
Why it matters: The ruling affirms federal authority over state laws that affect federal agents, shaping law enforcement operations and federal-state relations in Illinois.
- On August 20, 2026, a federal judge ruled DOJ has standing to sue over the Illinois Bivens Act and CASPA.
- The Illinois Bivens Act permits lawsuits against federal officers for civil rights violations, including punitive damages.
- CASPA bans civil arrests within 1,000 feet of state courthouses.
- DOJ alleges these laws unlawfully hinder federal law enforcement and immigration enforcement duties.
On August 20, 2026, Judge David Dugan denied Illinois's motion to dismiss a federal lawsuit filed by the U.S. Department of Justice challenging Illinois's Bivens Act and the Court Access, Safety and Participation Act (CASPA). The lawsuit was initially filed on December 22, 2025, against Governor J.B. Pritzker and Attorney General Kwame Raoul.
The Illinois Bivens Act allows individuals to sue federal law enforcement officers for civil rights violations, including seeking punitive damages. CASPA prohibits civil arrests on state courthouse grounds and within 1,000 feet of those courthouses.
The DOJ contends these laws interfere with federal authority and operations, particularly citing impacts on immigration law enforcement. As stated by the Justice Department, the laws represent "illegal attempts to regulate and discriminate against the federal government through novel causes of action" and pose safety risks to federal officers facing harassment and violence.
Judge Dugan found the DOJ plausibly alleged a conflict between the Illinois Bivens Act and federal law, as well as interference with executive branch duties. This grants the federal government standing to pursue its supremacy clause claims against these state statutes, signaling federal courts may scrutinize similar state laws that regulate federal officers.
By the numbers:
- August 20, 2026 — Date Illinois court denied motion to dismiss DOJ lawsuit
- December 22, 2025 — Date DOJ filed challenge to Illinois Bivens Act and CASPA
- 1,000 feet — Distance around courthouses where CASPA prohibits civil arrests
What's next: The case will proceed, with potential impacts on federal-state relations and enforcement protocols in Illinois and possibly other states.
