WASHINGTON (TNND) — A federal judge has issued a fourth block to President Donald Trump's executive order aimed at ending birthright citizenship.

U.S. District Judge Deborah Boardman of Maryland issued a preliminary injunction after the case was returned to her by an appeals court.

Since the Supreme Court ruled in June to limit nationwide injunctions, two other district courts, as well as an appellate panel of judges, have also blocked the birthright order.

Trump's January order would deny citizenship to children born to parents living in the U.S. illegally or temporarily.

Boardman in February issued a preliminary injunction blocking it nationwide. But the June ruling by the U.S. Supreme Court upended that decision and other court rulings blocking the order across the nation.

The justices ruled that lower courts generally can’t issue nationwide injunctions, but they didn’t rule out other court orders that could have nationwide effects, including in class-action lawsuits and those brought by states.

In her ruling Thursday, Boardman certified a class of all children who have been born or will be born in the United States after February 19, 2025, who would be affected by Trump's order.

She said the plaintiffs in the lawsuit before her were “extremely likely” to win their argument that the birthright order violates the 14th Amendment to the U.S. Constitution, which includes a citizenship clause that says all people born or naturalized in the United States, and subject to U.S. jurisdiction, are citizens. They were also likely to suffer irreparable harm if the order went into effect, she wrote.
