() A federal judge in New Hampshire has issued a temporary injunction blocking President Donald Trump’s executive order ending birthright citizenship after granting class action status in a lawsuit.

Judge Joseph LaPlante certified a class action lawsuit on behalf of children affected by Trump’s order, which includes those born to parents who are in the United States temporarily or illegally.

LaPlante’s decision includes a seven-day stay, allowing the government time to appeal.

Birthright citizenship is enshrined in the Constitution, and multiple legal challenges have been brought against the law. In the executive order, the administration argues that citizenship was never intended to apply to people born in the United States but “not subject to the jurisdiction thereof.”

The Supreme Court has not weighed in on the executive order itself, but justices recently issued a decision that limits the ability of federal judges to issue broad, nationwide injunctions.

While the decision limited the scope of rulings from federal judges, the court did leave room for broader injunctions in the case of class action suits, in which plaintiffs represent a large group of individuals.

The White House, which has used executive orders to enact controversial policies that have faced legal challenges, celebrated the Supreme Court’s ruling.
