Introduction
On June 30, 2026, the Supreme Court of the United States issued its opinion in Trump v. Barbara, No. 25-365, resolving one of the most consequential constitutional questions of recent decades: whether the Fourteenth Amendment's Citizenship Clause guarantees birthright citizenship to children born in the United States to parents who are unlawfully or temporarily present in the country.
The case arose from Executive Order No. 14160, issued by President Trump on January 20, 2025, and titled 'Protecting the Meaning and Value of American Citizenship.' The Order took the position that such children are not 'subject to the jurisdiction' of the United States and therefore do not qualify for citizenship under either the Fourteenth Amendment or the Immigration and Nationality Act (INA). The Court granted certiorari before judgment, bypassing the First Circuit, and ultimately held that children born in the United States to parents unlawfully or temporarily present are indeed citizens at birth.

Background: the executive order and the litigation below
Executive Order No. 14160, published at 90 Fed. Reg. 8449, directed that children born in the United States to parents who are either unlawfully present or only temporarily present would not be recognized as citizens under the Fourteenth Amendment or the INA, both of which use the phrase 'subject to the jurisdiction thereof' or equivalent language.
Several parents filed suit, some in the name of their children, arguing that the Order violated the Fourteenth Amendment and the INA. The district court agreed with the challengers, provisionally certified a nationwide class of children who would be denied citizenship under the Order, and issued a preliminary injunction against its enforcement. The Supreme Court then granted certiorari before judgment, taking the case directly from that posture rather than waiting for the First Circuit to rule.
The English common law foundation: jus soli and its exceptions
The Court began its analysis by situating the Citizenship Clause within its deep historical context, tracing the relevant legal tradition back to English common law. Under that tradition, children born within the sovereign's dominions owed a natural allegiance to the sovereign who protected them at birth, regardless of how 'momentary and uncertain' their presence. The Court cited Calvin's Case, 7 Co. Rep. 1a, 6a, 77 Eng. Rep. 377, 384, and Blackstone's Commentaries on the Laws of England for this proposition. Such children were therefore 'natural-born subjects.'
Critically, the opinion notes that the same rule applied to children born of parents who were themselves subject to expulsion. The exceptions to this principle were narrow: children born in lands the sovereign did not control, children born in areas temporarily outside the sovereign's control, and children of foreign ministers, the last of these resting on a legal fiction of extraterritoriality.
This common law doctrine — known as jus soli, or right of the soil — crossed the Atlantic and, according to the Court, prevailed in 'each and all of the states' after American independence, citing Kent's Commentaries on American Law. The Court observed that in a nation of immigrants, jus soli's broad scope took on particular importance, assuring that children of foreigners — including those present on a 'temporary sojourn,' as described in Lynch v. Clarke, 1 Sand. Ch. 583, 638, 663-664 (N.Y. Ch.) — would be American citizens by birth alone.
Dred Scott and the repudiation of blood-based citizenship
The Court then turned to the pivotal departure from common law represented by Dred Scott v. Sandford, 19 How. 393. In that decision, the Court had abandoned the soil-based rule and adopted the view that blood, not soil, determined citizenship, holding that those descended from slaves could not be citizens. The opinion in Trump v. Barbara describes the reaction to Dred Scott as one of shock, referencing the historical record, and notes that abolitionists committed themselves to undoing what the Court had done.
In the midst of the Civil War, Attorney General Edward Bates issued what the Court characterizes as a landmark opinion. Citing Calvin's Case and Kent's Commentaries, Bates rejected the premise that 'citizenship is ever hereditary' and declared that 'every person born in the country is, at the moment of birth, prima facie a citizen, . . . without any reference to race or color.' 10 Op. Atty Gen. 382, 394, 399. The exceptions Bates recognized were described as 'few' — limited to 'the small and admitted class of the natural-born composed of the children of foreign ministers and the like.'
Following the Civil War, Congress sought to codify Bates's opinion by enacting the Civil Rights Act of 1866, which made citizens of 'all persons born in the United States and not subject to any foreign power, excluding Indians not taxed.' The Court notes that the Act was understood at the time to invoke the common law rule, citing statements made during congressional debate.
The Fourteenth Amendment and the meaning of 'subject to the jurisdiction thereof'
The Court explained that what the Civil Rights Act of 1866 began, the Fourteenth Amendment would finish. The Amendment's Citizenship Clause provides that '[a]ll 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.'
According to the Court's analysis, the Citizenship Clause mirrored the common law's criteria for citizenship, starting with territory — a child must be 'born . . . in the United States' — and ending with sovereign power — a child must be 'subject to the jurisdiction' of the United States. The Court held that children born in the United States to parents unlawfully or temporarily present satisfy both of these criteria and are therefore citizens at birth under the Fourteenth Amendment.
The Court's holding thus directly rejected the premise of Executive Order No. 14160, which had treated the 'subject to the jurisdiction' language as excluding children of parents without lawful permanent status. In the Court's reading, that phrase tracks the narrow common law exceptions — such as children of foreign ministers — rather than creating a broad carve-out based on the immigration status of the parents.
Scope of the proceedings and the nationwide class
The case reached the Supreme Court in an unusual procedural posture. The district court had not only issued a preliminary injunction against enforcement of the Executive Order but had also provisionally certified a nationwide class of children who would be denied citizenship under it. The Supreme Court granted certiorari before judgment, meaning the First Circuit had not yet ruled when the Court agreed to hear the case.
The Court's decision to take the case at this early stage reflects the significance and urgency of the constitutional question presented, which affected a broad class of individuals across the country. The opinion's holding — that such children are citizens at birth — resolves the central legal dispute that animated both the district court proceedings and the certiorari petition.
Conclusion
Trump v. Barbara, No. 25-365, decided June 30, 2026, represents a significant ruling on the scope of birthright citizenship under the Fourteenth Amendment. The Supreme Court held, after tracing the doctrine from English common law through the Civil War era and the enactment of the Fourteenth Amendment, that children born in the United States to parents who are unlawfully or temporarily present are 'subject to the jurisdiction' of the United States and are therefore citizens at birth. The decision rejected the interpretation advanced in Executive Order No. 14160 and reaffirmed the broad, soil-based understanding of citizenship that the Court found embedded in the Amendment's text and history.
For those seeking to understand how the Court reached this conclusion, the opinion's detailed engagement with historical sources — from Calvin's Case and Blackstone to the debates surrounding the Civil Rights Act of 1866 and the Fourteenth Amendment — provides a thorough account of the legal tradition the Court found controlling. Readers with questions about how this decision may affect specific circumstances should seek guidance from a licensed immigration or constitutional law attorney.
