Lawyers representing four immigration legal service organizations on Thursday launched a federal lawsuit in the Southern District of New York aimed at thwarting the Trump administration’s reported plan to deport thousands of undocumented immigrants as part of a series of nationwide raids expected in the coming weeks.

The lawsuit, filed preemptively by the American Civil Liberties Union, New York Civil Liberties Union and law firm Munger, Tolles, & Olson, argued the due process rights of those immigrants require that they be offered an immigration hearing prior to deportation. The legal action appeared to come in response to news reports that broke Thursday saying that nationwide ICE raids of undocumented families—backed by President Trump and reportedly first thought to be happening in June—would begin this Sunday.
