A federal judge on Friday blocked Immigration and Customs Enforcement’s “expedited removal” deportation strategy to detain paroled immigrants as quickly as possible.

U.S. District Judge Jia Cobb of the District of Columbia ruled that the Trump administration’s use of expedited removal exceeded the Department of Homeland Security’s legal authority, in addition to being arbitrary and capricious. The order temporarily halts the federal government’s efforts to deport immigrants previously paroled into the United States at a port of entry.
