Fact Summary
The litigation is a landmark constitutional challenge to an Executive Order signed by President Donald Trump on January 20, 2025, which seeks to end the practice of automatic birthright citizenship for children born in the United States to parents who are not U.S. citizens or lawful permanent residents (specifically those present temporarily or unlawfully).
The lead plaintiff, Barbara, represents a certified nationwide class of infants born after February 20, 2025, who would be denied U.S. citizenship under the terms of the order. The challenge was brought by a coalition of civil rights groups, including the ACLU and the Legal Defense Fund.
The core legal and factual dispute centers on the interpretation of the Citizenship Clause of the Fourteenth 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, represented by Solicitor General D. John Sauer, argues that "subject to the jurisdiction" implies a requirement of "complete political allegiance." Under this theory, children of foreign nationals—who owe allegiance to a different sovereign—do not fall within the intended scope of the Amendment as it was understood by its framers in 1868.
The plaintiffs contend that the Clause codified the centuries-old common law rule of jus soli (right of the soil), where birth within the territory is the sole requirement for citizenship. They rely on the 1898 Supreme Court precedent United States v. Wong Kim Ark, which affirmed citizenship for a child born in the U.S. to Chinese parents who were not eligible for naturalization.
The factual record includes the administration's assertion that the order "restores" the original meaning of the Constitution to prevent "birth tourism" and the creation of a "permanent subclass" of individuals. Conversely, the plaintiffs provided evidence that the order would impact over 200,000 children annually, stripping them of access to passports, federal benefits, and protection from deportation.
