A federal judge ruled Thursday that immigration enforcement officers are conducting warrantless arrests using guidance that fails to meet constitutional probable cause standards, marking a significant rebuke of practices implemented during Trump administration immigration sweeps.
U.S. District Judge Beryl A. Howell in Washington, D.C., continuing a preliminary injunction she issued in December 2025, said that when conducting civil immigration arrests without a warrant in the District, defendants shall not rely on the probable cause standard or analytical approach set forth in the five-page memorandum from the former acting director of Immigration and Customs Enforcement.
Constitutional Protections at Stake
The judge found the instructions failed to tell officers to assess a person's connections to the community before concluding that person is a flight risk and therefore needs to be taken into custody immediately. This omission raises fundamental questions about whether enforcement practices adequately protect Fourth Amendment rights against unreasonable searches and seizures.
The action is the latest step in a lawsuit filed in 2025 by four noncitizens and the nonprofit organization CASA in Washington challenging their arrests during immigration sweeps by the federal agency, which were part of a law-enforcement surge ordered by President Donald Trump.
Advocates Secure Documentation Victory
Howell approved another request by the plaintiffs seeking more records to help explain how the policy will be implemented, but she rejected some of their arguments and said the government had adhered to her preliminary injunction order on some issues. The additional records could provide crucial transparency into how immigration enforcement agencies are interpreting their arrest authority.
Madeleine Gates, associate counsel at the Washington Lawyers' Committee for Civil Rights and Urban Affairs, said, "We got what we were asking for essentially." She said the ruling "reaffirms that federal agents have to comply with the law. They do not get a pass in doing immigration enforcement."
Gates also said, "This particular case is all about what happens at the outset, before the arrest is made."
Government Defends Practices
The Department of Homeland Security responded to questions about Thursday's order in an email saying, "ICE has authority for lawful arrests." The email said, "Law enforcement officers use 'reasonable suspicion' to investigate immigration status and probable cause to make arrests consistent with the Fourth Amendment to the U.S. Constitution," and added, "The Supreme Court has already vindicated us on these practices."
The government's assertion that its practices have been vindicated came even as the judge determined the current guidance does not meet constitutional standards for warrantless civil immigration arrests in the District.
Why This Matters:
This ruling addresses fundamental questions about how constitutional protections apply to immigrant communities and whether federal enforcement agencies can bypass procedural safeguards when conducting civil arrests. The judge's finding that officers must assess community ties before determining flight risk establishes that immigrants are entitled to individualized consideration rather than blanket enforcement approaches. For the four noncitizens and countless others subject to immigration sweeps, the decision reinforces that law enforcement authority has limits even in immigration enforcement. The requirement for additional documentation could provide transparency into practices that have operated with limited public scrutiny, allowing communities and advocates to hold federal agencies accountable to constitutional standards that protect all people in the United States regardless of immigration status.
