A federal judge in Denver on Tuesday ordered federal immigration officers to stop making arrests in Colorado without a warrant, unless the detainee posed a flight risk, the latest in a string of lower-court decisions rebuking President Trump’s immigration enforcement tactics.

The ruling by Judge R. Brooke Jackson could be put on hold once the administration appeals, just as earlier rulings in Los Angeles and Illinois limiting immigration agents’ powers were quickly blocked by higher courts.

In Colorado, Judge Jackson, an appointee of President Barack Obama, found that immigration agents had acted unlawfully by arresting and detaining immigrants — some for as long as 100 days — without showing the required probable cause that they posed a threat of fleeing.
