CONCORD, N.H. (AP) 鈥 A federal judge in New Hampshire issued a ruling Thursday prohibiting President Donald Trump鈥檚 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鈥檚 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 that limited judges鈥 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.

鈥淭his is going to protect every single child around the country from this lawless, unconstitutional and cruel executive order,鈥 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鈥檚 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鈥檚 14th Amendment, which states: 鈥淎ll persons born or naturalized in the United States and subject to the jurisdiction thereof, are citizens of the United States.鈥 The Trump administration says the phrase 鈥渟ubject to the jurisdiction thereof鈥 means the U.S. can deny citizenship to babies born to women in the country illegally, ending what has been seen as an of U.S. law for more than a century.

鈥淧rior misimpressions of the citizenship clause have created a perverse incentive for illegal immigration that has negatively impacted this country鈥檚 sovereignty, national security, and economic stability,鈥 government lawyers wrote in the New Hampshire case.

LaPlante, who had issued a narrow injunction in a similar case, said while he didn鈥檛 consider the government鈥檚 arguments frivolous, he found them unpersuasive. He said his decision to issue an injunction was 鈥渘ot a close call鈥 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鈥檚 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.

鈥淣o one has to move states right this instant,鈥 she said. 鈥淭here鈥檚 different avenues through which we are all fighting, again, to make sure that this executive order never actually sees the light of day.鈥

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.

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

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 鈥 his wife's father is a U.S. citizen.

鈥淢y baby has the right to citizenship and a future in the United States,鈥 he wrote.
