The United States filed a lawsuit against Connecticut and New Haven on April 13, 2026, in the U.S. District Court for the District of Connecticut, challenging state and local immigration policies that allegedly interfere with federal enforcement efforts. The complaint alleges that Connecticut's Trust Act and Policy Guidance, along with New Haven's Executive Order, unlawfully restrict law enforcement cooperation with federal immigration authorities by prohibiting compliance with immigration detainers, limiting communication about custody status, and restricting federal access to interview detained individuals. The federal government brought eight counts against the defendants, including Governor Ned Lamont, Attorney General William Tong, and New Haven Mayor Justin Elicker in their official capacities, alleging violations of the Supremacy Clause and federal immigration statutes. The United States seeks declaratory and injunctive relief to invalidate these policies, along with attorney's fees and costs.

Notice to Counsel and Litigants Regarding AI-Assisted Research: Attorneys and pro se litigants alike should exercise great caution in submitting any AI-generated language in filings before the Court. Use of AI without verification of the accuracy of the information it generates like any other shoddy research method from other sources or tools implicates Federal Rule of Civil Procedure 11, the central purpose of which is to deter baseless filings in district court and thus to streamline the administration and procedure of the federal courts. Rule 11 applies fully to actions filed by pro se litigants.Therefore, all parties are on notice that the Court has a no-tolerance policy for any briefing (AI-assisted or not) that hallucinates legal propositions or otherwise severely misstates the law. Such filings will often result in sanctions absent reasonable excuse. See generally Willis v. U.S. Bank Nat'l Ass'n et al, No. 3:25-CV-516-BN, 2025 WL 1408897 (N.D. Tex. May 15, 2025).
