A judge for the US District Court for the District of Maryland granted a preliminary injunction at a hearing on Wednesday against President Donald Trump’s executive order seeking to end all birthright citizenship.

The plaintiffs, CASA, Inc., Asylum Advocacy Project, and five pregnant mothers under pseudonyms, filed the lawsuit against Trump, among other government officials, in response to his executive order that effectively abrogates birthright citizenship for children born in the US to non-citizens, including both documented and undocumented parents.

In her decision, Judge Deborah Boardman found that the plaintiffs have shown they are likely to “succeed on the merits of their claim that the Executive Order violates the Fourteenth Amendment.” Boardman also determined the plaintiffs have shown they will “suffer irreparable harm without injunctive relief” since there will be ambiguity about their children’s citizenship status, which could result in them becoming stateless. She found support in the balance of equities and the public interest analysis for granting the plaintiff’s injunction since the government will not be harmed as the injunction will “maintain the status quo.”

One of the plaintiffs made a statement in response to Boardman’s ruling: “This ruling will give mothers like me a bit of temporary relief as we navigate pregnancy and the uncertain future for our babies.” George Escobar, CASA’s chief of programs and services, stated:

This is a victory for our families, for our communities, and for the Constitution of the United States. This is the level of fight that will be required for the next four years of the Trump administration. The pregnant women who took this case up against President Trump — and so many immigrants across the country — can breathe easier knowing that their precious children are citizens and afforded the full rights that come with that.

Another federal judge previously blocked the executive order. That judge found a “strong likelihood” that the executive order violates constitutional rights to citizenship protected by the Fourteenth Amendment and the Immigration and Nationality Act. White House Press Secretary Karoline Leavitt explained in a press briefing in late January that the Trump administration is “prepared to fight this [case] all the way to the Supreme Court if we have to, because President Trump believes” the executive order is a “necessary step to secure our nation’s borders.”
