BOSTON — A federal appeals court in Boston ruled on Friday that the Trump administration cannot withhold citizenship from children born to people in the country illegally or temporarily, adding to the mounting legal setbacks for the president’s birthright order.

A three-judge panel of the 1st U.S. Circuit Court of Appeals became the fifth federal court since June to either issue or uphold orders blocking the president’s birthright order. The court concluded that the plaintiffs are likely to succeed on their claims that the children described in the order are entitled to birthright citizenship under the Citizenship Clause of the 14th Amendment.

The panel upheld lower courts’ preliminary injunctions, which blocked the birthright order while lawsuits challenging it moved ahead. The order, signed the day the president took office in January, would halt automatic citizenship for babies born to people in the U.S. illegally or temporarily.
