A federal judge in New Hampshire on Thursday temporarily barred the Trump administration from enforcing its executive order that would end automatic U.S. citizenship for children born in the country to parents who are in the United States unlawfully or only temporarily. U.S. District Judge Joseph Laplante certified a nationwide class of “all current and future children” potentially affected and issued a preliminary injunction, pausing it for seven days to allow the government to appeal. Laplante, a George W. Bush appointee, held that stripping citizenship posed “irreparable harm” and was likely inconsistent with the Fourteenth Amendment’s Citizenship Clause. His decision restores a coast-to-coast block on the measure less than two weeks after the Supreme Court, in a 6-3 decision on 27 June, limited lower courts’ ability to impose nationwide injunctions while expressly allowing such relief in certified class actions. The high court had given the administration 30 days to start implementing the policy in 28 states that were not party to earlier suits. The executive order, signed by President Donald Trump on 20 January, is now frozen pending further litigation. The Justice Department is expected to seek relief from the First Circuit, setting up another confrontation over presidential authority on immigration as multiple challenges, led by the American Civil Liberties Union and other advocates, move through the courts.
