The proposed General Assembly Raised Bill No. 5439 seeks to amend Section 54-192h of the general statutes concerning civil immigration detainers, specifically limiting the authority of law enforcement agencies in detaining individuals based on these requests. The bill introduces the definition of "civil immigration detainer" and stipulates that law enforcement cannot arrest or detain individuals solely on such detainers unless they have been charged with a class A, B, or C felony or a family violence crime. It deletes previous requirements that allowed law enforcement to act on civil immigration detainers only with a judicial warrant or prior convictions for specific offenses, thereby narrowing the conditions under which detainers can be enforced.

Additionally, the bill allows for the detention of individuals for up to forty-eight hours if the detainer is accompanied by a judicial warrant, the individual has been charged with serious felonies or family violence crimes, or if they are identified in the federal Terrorist Screening Database. It mandates that law enforcement agencies provide individuals with a copy of the detainer and inform them of their compliance intentions, while also requiring municipalities to report data on ICE access biannually. The legislation emphasizes that no expanded authority is granted to law enforcement based solely on civil immigration detainers, and municipalities may face legal action for violations, allowing individuals to seek injunctive or declaratory relief. The act is set to take effect on October 1, 2026.
