A federal judge on Friday dismissed a Trump administration lawsuit seeking to block sanctuary state laws in Illinois that limit the cooperation of local law enforcement with federal immigration agencies.

Judge Lindsay C. Jenkins of the Northern District of Illinois, Eastern Division, said in her ruling that the 10th Amendment, which protects people from federal government overreach, protected local law enforcement's decision to avoid cooperation with Immigration and Customs Enforcement (ICE) and other immigration agencies.

It would allow the federal government to take over states under the guise of intergovernmental immunity” exactly the kind of direct regulation of states prohibited by the 10th Amendment, Jenkins wrote of the lawsuit, which named Illinois, the city of Chicago and a number of local officials as defendants. Jenkins ruled that the Trump administration “lacks standing” to invalidate state, city, and county laws limiting cooperation with federal immigration authorities, adding in his ruling that “contrary to the United States’ arguments, the Sanctuary Policies here do not comparably regulate the operations of Immigration and Customs Enforcement (ICE) or interfere with the contractual rights of private individuals who work with ICE.” The individual defendants are dismissed because the United States lacks standing to sue them in connection with the Sanctuary Policies; the Cook County Board of Commissioners is dismissed because it is not a suable entity independent of Cook County… The U.S. lawsuit is dismissed in its entirety without prejudice, Jenkins wrote.

Illinois prevents local officials from providing immigration information that is not publicly available, while Chicago prohibits them from responding to ICE inquiries without a court order. State officials are also prohibited from complying with immigration detainers.

President Donald Trump continues to crack down on his immigration policy, targeting what he calls sanctuary cities, whose policies limit local cooperation with federal immigration enforcement, and has threatened legal action against state and local authorities that don't comply.

Illinois' Democratic Governor JB Pritzker, a potential 2028 presidential candidate, celebrated the judge's ruling.

Illinois just beat the Trump administration in federal court. His case against the bipartisan TRUST Act was dismissed. Unlike the president, we follow the law and listen to the courts, Pritzker wrote in a post on X.

The Chicago lawsuit was one of several ongoing legal battles against Democratic-leaning states and cities that the Trump administration has accused of unlawfully obstructing the enforcement of federal immigration laws.

On Thursday, the Justice Department sued New York City and its leaders, accusing them of pursuing sanctuary city policies that hinder enforcement of the Trump administration's immigration laws.
