CONCORD, N.H. (AP) — A federal judge in New Hampshire issued a ruling Thursday prohibiting President Donald Trump’s executive order ending birthright citizenship from taking effect anywhere in the U.S.

Judge Joseph LaPlante issued a preliminary injunction blocking Trump’s order and certified a class action lawsuit including all children who will be affected. The order, which followed an hour-long hearing, included a seven-day stay to allow for appeal.

The judge’s decision puts the birthright citizenship issue on a fast track to return to the Supreme Court. The justices could be asked to rule whether the order complies with their decision last month that limited judges’ authority to issue nationwide injunctions.

The class is slightly narrower than that sought by the plaintiffs, who wanted to include parents, but attorneys said that wouldn’t make a material difference.

“This is going to protect every single child around the country from this lawless, unconstitutional and cruel executive order,” said Cody Wofsy, an attorney for the plaintiffs.

The lawsuit was filed on behalf of a pregnant woman, two parents and their infants. It’s among numerous cases challenging Trump’s January order denying citizenship to those born to parents living in the U.S. illegally or temporarily. The plaintiffs are represented by the American Civil Liberties Union and others.

At issue is the Constitution’s 14th Amendment, which states: “All persons born or naturalized in the United States and subject to the jurisdiction thereof, are citizens of the United States.” The Trump administration says the phrase “subject to the jurisdiction thereof” means the U.S. can deny citizenship to babies born to women in the country illegally, ending what has been seen as an intrinsic part of U.S. law for more than a century.

“Prior misimpressions of the citizenship clause have created a perverse incentive for illegal immigration that has negatively impacted this country’s sovereignty, national security, and economic stability,” government lawyers wrote in the New Hampshire case.

LaPlante, who had issued a narrow injunction in a similar case, said while he didn’t consider the government’s arguments frivolous, he found them unpersuasive. He said his decision to issue an injunction was “not a close call” and that deprivation of U.S. citizenship clearly amounted to irreparable harm.

In a Washington state case before the 9th U.S. Circuit Court of Appeals, the judges have asked the parties to write briefs explaining the effect of the Supreme Court’s ruling. Washington and the other states in that lawsuit have asked the appeals court to return the case to the lower court judge.

As in New Hampshire, a plaintiff in Maryland seeks to organize a class-action lawsuit that includes every person who would be affected by the order. The judge set a Wednesday deadline for written legal arguments as she considers the request for another nationwide injunction from CASA, a nonprofit immigrant rights organization.

Ama Frimpong, legal director at CASA, said the group has been stressing to its members and clients that it is not time to panic.

“No one has to move states right this instant,” she said. “There’s different avenues through which we are all fighting, again, to make sure that this executive order never actually sees the light of day.”

The New Hampshire plaintiffs, referred to only by pseudonyms, include a woman from Honduras who has a pending asylum application and is due to give birth to her fourth child in October. She told the court the family came to the U.S. after being targeted by gangs.

“I do not want my child to live in fear and hiding. I do not want my child to be a target for immigration enforcement,” she wrote. “I fear our family could be at risk of separation.”

Another plaintiff, a man from Brazil, has lived with his wife in Florida for five years. Their first child was born in March, and they are in the process of applying for lawful permanent status based on family ties — his wife’s father is a U.S. citizen.

“My baby has the right to citizenship and a future in the United States,” he wrote.

WASHINGTON (AP) — A divided Supreme Court on Friday ruled that individual judges lack the authority to grant nationwide injunctions, but the decision left unclear the fate of President Donald Trump’s restrictions on birthright citizenship.

The outcome was a victory for the Republican president, who has complained about individual judges throwing up obstacles to his agenda.

But a conservative majority left open the possibility that the birthright citizenship changes could remain blocked nationwide. Trump’s order would deny citizenship to U.S.-born children of people who are in the country illegally.

The cases now return to lower courts, where judges will have to decide how to tailor their orders to comply with the high court ruling, Justice Amy Coney Barrett wrote in the majority opinion. Enforcement of the policy can’t take place for another 30 days, Barrett wrote.

The justices agreed with the Trump administration, as well as President Joe Biden’s Democratic administration before it, that judges are overreaching by issuing orders that apply to everyone instead of just the parties before the court.

The president, making a rare appearance to hold a news conference in the White House briefing room, said that the decision was “amazing” and a “monumental victory for the Constitution,” the separation of powers and the rule of law.

In dissent, Justice Sonia Sotomayor wrote, “The court’s decision is nothing less than an open invitation for the government to bypass the Constitution.” This is so, Sotomayor said, because the administration may be able to enforce a policy even when it has been challenged and found to be unconstitutional by a lower court.

Rights groups that sued over the policy filed new court documents following the high court ruling, taking up a suggestion from Justice Brett Kavanaugh that judges still may be able to reach anyone potentially affected by the birthright citizenship order by declaring them part of “putative nationwide class.” Kavanaugh was part of the court majority on Friday but wrote a separate concurring opinion.

States that also challenged the policy in court said they would try to show that the only way to effectively protect their interests was through a nationwide hold.

“We have every expectation we absolutely will be successful in keeping the 14th Amendment as the law of the land and of course birthright citizenship as well,” said Attorney General Andrea Campbell of Massachusetts.

Birthright citizenship automatically makes anyone born in the United States an American citizen, including children born to mothers in the country illegally. The right was enshrined soon after the Civil War in the Constitution’s 14th Amendment.

In a notable Supreme Court decision from 1898, United States v. Wong Kim Ark, the court held that the only children who did not automatically receive U.S. citizenship upon being born on U.S. soil were the children of diplomats, who have allegiance to another government; enemies present in the U.S. during hostile occupation; those born on foreign ships; and those born to members of sovereign Native American tribes.

The U.S. is among about 30 countries where birthright citizenship — the principle of jus soli or “right of the soil” — is applied. Most are in the Americas, and Canada and Mexico are among them.

Trump and his supporters have argued that there should be tougher standards for becoming an American citizen, which he called “a priceless and profound gift” in the executive order he signed on his first day in office.

The Trump administration has asserted that children of noncitizens are not “subject to the jurisdiction” of the United States, a phrase used in the amendment, and therefore are not entitled to citizenship.

But states, immigrants and rights groups that have sued to block the executive order have accused the administration of trying to unsettle the broader understanding of birthright citizenship that has been accepted since the amendment’s adoption.

Judges have uniformly ruled against the administration.

The Justice Department had argued that individual judges lack the power to give nationwide effect to their rulings.

The Trump administration instead wanted the justices to allow Trump’s plan to go into effect for everyone except the handful of people and groups that sued. Failing that, the administration argued that the plan could remain blocked for now in the 22 states that sued. New Hampshire is covered by a separate order that is not at issue in this case.

The justice also agreed that the administration may make public announcements about how it plans to carry out the policy if it eventually is allowed to take effect.
