Groups File Nationwide Class-Action Lawsuit Over Trump Birthright Citizenship Order

The new lawsuit comes in response to today’s Supreme Court ruling restricting courts' ability to block illegal federal policies using nationwide injunctions.

Immigrants' rights’ advocates today filed a new nationwide class-action lawsuit challenging the Trump administration’s executive order restricting birthright citizenship. The lawsuit is in response to today’s Supreme Court ruling that potentially opens the door for partial enforcement of the executive order.

This new case was filed by the American Civil Liberties Union, ACLU of New Hampshire, ACLU of Maine, ACLU of Massachusetts, Legal Defense Fund, Asian Law Caucus, and Democracy Defenders Fund on behalf of a proposed class of babies subject to the executive order, and their parents.

The same group of organizations filed a similar suit in January 2025 in the same court, on behalf of groups with members whose babies born on U.S. soil will be denied citizenship under the order, including New Hampshire Indonesian Community Support, League of United Latin American Citizens (LULAC), and Make the Road New York. The court issued a ruling protecting members of those organizations, and that case is pending at the First Circuit Court of Appeals, with oral argument set for August 1.

Three other lawsuits originally obtained nationwide injunctions protecting everyone subject to the order, but the Supreme Court’s decision narrowed those injunctions, potentially leaving some children without protection.

This new case seeks protection for all families in the country, filling the gaps that may be left by the existing litigation.

Birthright citizenship is the principle that every baby born in the United States is a U.S. citizen. The Constitution’s 14th Amendment guarantees the citizenship of all children born in the United States (with the extremely narrow exception of children of foreign diplomats) regardless of race, color, or ancestry. Specifically, it states that “all persons born or naturalized in the United States, and subject to the jurisdiction thereof, are citizens of the United States and of the state wherein they reside.”

Today’s lawsuit charges the Trump administration with flouting the Constitution, congressional intent, and longstanding Supreme Court precedent, and it is national in scope.

“Every court to have looked at this cruel order agrees that it is unconstitutional,” said Cody Wofsy, deputy director of the ACLU’s Immigrants’ Rights Project and lead attorney in this case. “The Supreme Court’s decision did not remotely suggest otherwise, and we are fighting to make sure President Trump cannot trample on the citizenship rights of a single child.”

“This executive order directly opposes our Constitution, values, and history, and it would create a permanent, multigenerational subclass of people born in the U.S. but who are denied full rights. No politician can ever decide who among those born in our country is worthy of citizenship — and we will keep fighting to ensure that every child born in the United States has their right to citizenship protected,” said Devon Chaffee, executive director of the ACLU of New Hampshire.

“While some of this week's decisions have the potential to shift our legal strategies, they will not change the commitments the ACLU has held for over 100 years,” said Molly Curren Rowles, executive director of the ACLU of Maine. “The constitutional principles that form the foundation of freedom in this country have always been challenging, complex, and multifaceted. The president’s executive order violates the plain language of the 14th Amendment and flouts fundamental American values.”
