What the Birthright Citizenship Case Means for the 14th Amendment

Last updated 7 months ago. Our resources are updated regularly but please keep in mind that links, programs, policies, and contact information do change.

On January 20, 2025, President Trump signed an executive order attempting to end automatic birthright citizenship for children born in the United States to parents without citizenship or green cards. Federal judges blocked it within weeks. The Supreme Court agreed to hear the case in late 2025, with oral arguments expected in early 2026 and a decision by late June or early July 2026.

The outcome will determine who gets to be a citizen and signal whether this Supreme Court believes constitutional meaning was fixed in 1868 or evolves with changing circumstances. The methodology—originalism versus living constitutionalism—will reshape how the Court approaches voting rights, equal protection, due process, and nearly every other constitutional question for decades.

The entire dispute hinges on five words in the 14th Amendment: “subject to the jurisdiction thereof.”

The Citizenship Clause and “Subject to the Jurisdiction Thereof”

The citizenship clause of the 14th Amendment reads: “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.”

For 127 years, since the Supreme Court’s 1898 decision in United States v. Wong Kim Ark, that language has meant nearly everyone born on American soil becomes a citizen—regardless of their parents’ immigration status. When he tried to return from a trip to China, federal authorities denied him entry, claiming he wasn’t a citizen. The Supreme Court disagreed, 6-to-2.

Two legal minds can read “subject to the jurisdiction thereof” and arrive at completely opposite conclusions about what it means.

The broad interpretation—currently the law—holds that “subject to jurisdiction” means subject to ordinary U.S. law. If you’re in the United States and can be prosecuted in U.S. courts, arrested by U.S. police, sued in U.S. civil courts, you’re subject to jurisdiction. Under this reading, the only exceptions are children of foreign diplomats (who have legal immunity under international law) and children born to invading enemy armies. Everyone else born on U.S. soil: citizen.

The narrow interpretation argues that “subject to jurisdiction” means complete political allegiance. Someone here unlawfully hasn’t submitted to U.S. jurisdiction—they’re here against U.S. law. Someone on a temporary visa retains allegiance to their home country. The jurisdiction clause, on this reading, requires not territorial presence but complete political jurisdiction—the kind owed by citizens or permanent residents who’ve accepted American sovereignty.

The interpretive method the Court uses to resolve this question will apply to every other constitutional provision written in broad language.

What the Historical Record Shows

Both sides claim history supports their interpretation. The historical record is contradictory enough that they’re both partly right.

The 14th Amendment emerged from Reconstruction, designed to overturn Dred Scott v. Sandford, the 1857 decision declaring that Black people could never be citizens. On that, everyone agrees.

Congressional debates from 1866-1868 show that legislators discussed other groups too. Senator Jacob Howard, who introduced the citizenship language, explicitly said “Indians not taxed” would be excluded because they owed allegiance to their tribes rather than to the United States.

Some members of Congress worried about Chinese immigrants. Would their children become citizens under this broad language? The debates suggest different legislators had different answers.

When the historical evidence is contradictory, originalism doesn’t automatically provide answers. Judges still have to make judgments about which sources to credit and how to resolve conflicts.

The Trump administration points to statements by individual senators suggesting a narrow reading. But those same debates include other senators articulating a broad reading. The text Congress adopted doesn’t include explicit carve-outs for children of non-citizens. The Constitution is specific about exclusions elsewhere—it explicitly excludes “Indians not taxed” from the apportionment calculation. If the framers wanted to exclude children of certain immigrant categories from citizenship, they could have said so.

Wong Kim Ark and Precedent

For 127 years, Wong Kim Ark has been settled law. Federal agencies issue citizenship documents based on it. State governments recognize birthright citizenship based on it.

The doctrine of stare decisis—Latin for “to stand by things decided”—holds that courts should follow prior decisions unless there are strong grounds for overturning them. Factors include: the quality of the prior decision’s reasoning, whether it has become unworkable, whether people have relied on it heavily, whether circumstances have changed, and whether subsequent constitutional developments have undermined it.

Recent Supreme Court decisions suggest the current Court applies a less demanding standard. In Dobbs v. Jackson Women’s Health Organization (2022), the Court overturned Roe v. Wade after nearly fifty years. That same term, the Court overturned other longstanding precedents by focusing on what it called the “quality of reasoning” in prior cases.

The Trump administration’s petition argues that Wong Kim Ark was wrongly decided—that it misread the historical sources and gave insufficient weight to the jurisdictional requirement. If the current Court finds this persuasive, and if it applies the reasoning from Dobbs, the path to overturning 127 years of precedent becomes clear. The administration doesn’t need to show massive reliance or changed circumstances. It only needs to convince the Court that Wong Kim Ark was poorly reasoned from the start.

Justice Horace Gray’s majority opinion in Wong Kim Ark rested on some questionable historical claims. He asserted that English common law principles about birthright citizenship directly carried over to American constitutional law. Justice Fuller’s dissent argued that the founders had consciously rejected English feudalism, in which birthplace alone conferred allegiance. Fuller contended the Constitution required something more than mere birth on soil—it required complete allegiance.

Fuller lost that argument in 1898. But his dissent provides a roadmap for the current Court if it wants to reverse course.

Originalism Versus Living Constitutionalism

The birthright citizenship case will answer whether judges should interpret the Constitution based on what it meant to the people who wrote it in 1868, or whether constitutional meaning should evolve with modern circumstances.

Originalism holds that constitutional meaning is fixed at the time of adoption. To determine what the 14th Amendment means, originalists consult dictionaries from 1868, legislative debates, newspaper coverage, and other historical sources that shed light on how educated people of that era would have understood the words. Originalists argue this approach constrains judicial discretion by tying interpretation to objective historical facts rather than judges’ policy preferences.

Living constitutionalism holds that constitutional meaning can and should evolve. This doesn’t mean the Constitution means whatever judges want. It means judges should interpret constitutional provisions in light of modern circumstances, contemporary understanding of the relevant principles, and practical consequences. The Constitution uses general language deliberately—”liberty,” “due process,” “equal protection”—language that cannot be confined to the specific applications the framers anticipated.

If the Court overturns Wong Kim Ark in the name of originalism, it signals that originalism will reshape other areas of law. Voting rights cases would be reconsidered under the original public meaning of voting and representation provisions. Due process protections might be limited to those specifically identified in 1868. Equal protection doctrine would be reassessed through an originalist lens.

The methodology established here will guide the Court’s reasoning in cases about religious liberty, criminal justice, regulatory power, and fundamental rights for years to come.

The 14th Amendment as an Integrated Whole

Section 1 of the 14th Amendment contains four distinct clauses: the citizenship clause, the privileges or immunities clause, the due process clause, and the equal protection clause.

These clauses are interconnected. The citizenship clause establishes who is a citizen—the group whose privileges and immunities are especially protected. But the due process and equal protection clauses extend to all “persons,” not just citizens.

If the Court narrows citizenship by reading “subject to jurisdiction” restrictively, what does this mean for the equal protection clause, which protects “any person within its jurisdiction”? The word “jurisdiction” appears in both places. Originalist methodology typically reads the same language consistently throughout a document.

In Plyler v. Doe (1982), the Supreme Court held that states couldn’t deny free public education to undocumented children without showing a substantial government interest. Plyler relied partly on reasoning that extended the equal protection clause beyond citizenship—that persons within a state’s jurisdiction deserve protection even without citizenship. If the citizenship clause is narrowed, does this weaken the doctrinal foundation for Plyler?

The equal protection clause provided the basis for Brown v. Board of Education, which struck down racial segregation. It has been the foundation for cases protecting voting rights, marriage rights, and gender equality. The due process clause has protected privacy rights, fundamental liberties, and fair procedures.

If the Court demonstrates willingness to narrow the citizenship clause by adopting a restrictive reading of “subject to jurisdiction,” this suggests it might also adopt more restrictive readings of the equal protection and due process clauses.

When the Supreme Court Reverses Precedent

The Supreme Court doesn’t overturn longstanding precedents often. But it does happen, and understanding when and why helps predict what might occur in the birthright citizenship case.

The most dramatic reversal in modern constitutional history came with Brown v. Board of Education (1954), which overturned Plessy v. Ferguson (1896). Plessy had held that racially “separate but equal” facilities were constitutional. For fifty-eight years, Plessy was settled law. States organized their entire systems of public education, transportation, and services around it. Yet Chief Justice Earl Warren led a unanimous Court to overturn Plessy, concluding that separate was inherently unequal.

Another major reversal came with West Coast Hotel Co. v. Parrish (1937), which overturned the Lochner era jurisprudence that had struck down numerous economic regulations. For roughly four decades, the Court had held that the due process clause protected a “liberty of contract” that limited government’s ability to regulate business. The Court reversed course under pressure from the New Deal, fundamentally reconceiving what the due process clause protected.

Dobbs v. Jackson Women’s Health Organization (2022) overturned Roe v. Wade after nearly fifty years.

These reversals share patterns: the justices have changed, bringing new perspectives; the prior precedent is thought by the new majority to have been wrongly decided from the start; there is doubt about the strength of the prior reasoning; some time has passed; and there is a clear alternative principle the Court can articulate.

In the birthright citizenship case, all these factors might align. The Court’s personnel has changed since 2016, when Gorsuch, Kavanaugh, and Barrett replaced Scalia, Kennedy, and Ginsburg. The new majority appears to believe Wong Kim Ark was wrongly reasoned based on originalist grounds. More than 125 years have passed. The alternative principle—that “subject to jurisdiction” requires more than mere territorial jurisdiction—is available for the Court to articulate.

But the birthright citizenship case differs from these precedents in one respect. Brown and West Coast Hotel both involved reversals of doctrines that had become increasingly problematic or unworkable over time. Wong Kim Ark has been relatively straightforward and stable for 127 years. It hasn’t been generating massive litigation or practical problems. People know how to apply it.

This is one reason the stare decisis argument is stronger here than it was for Roe.

The Statelessness Problem

If the Supreme Court narrows birthright citizenship, it could create stateless persons—individuals with no recognized nationality in any country.

The Convention on the Reduction of Statelessness (1961) requires signatories to confer nationality on individuals born in their territory who would otherwise be stateless at birth. The United States hasn’t ratified this convention, citing conflicts with U.S. constitutional principles regarding voluntary renunciation of citizenship.

If the Court narrows birthright citizenship, it would create a category of individuals born in the United States who wouldn’t automatically acquire U.S. citizenship. As these individuals matured, they might encounter situations where their parents’ countries of origin wouldn’t recognize them as citizens either—if those countries follow different citizenship principles, such as limiting citizenship to those with citizen parents.

These individuals would be born in the U.S. with U.S. birth certificates, educated in U.S. schools, with no other home, yet potentially not recognized as citizens of any country.

The Trump administration’s implementation guidance suggests such individuals would be allowed to acquire their parents’ immigration status or register for provisional status. But this isn’t the same as citizenship. Someone with lawful permanent resident status enjoys many legal benefits but lacks full political rights—voting, certain federal employment—and remains subject to deportation for criminal conduct. Someone with merely provisional status would have even fewer rights.

The U.S. regularly criticizes other countries for creating stateless populations or denying citizenship to groups arbitrarily. In 2017, Myanmar’s government stripped hundreds of thousands of Rohingya Muslims of citizenship, creating a massive refugee crisis. The U.S. condemned this action.

If the U.S. Supreme Court narrows birthright citizenship, it would be adopting a policy that risks creating the kind of statelessness the U.S. typically criticizes elsewhere. This isn’t a knock-down legal argument—the U.S. has sovereignty to define citizenship within its own borders—but it’s a practical consideration that courts sometimes weigh when interpreting constitutional provisions.

How to Follow the Case

The Supreme Court will hear oral arguments in Barbara v. Trump sometime this spring, with a decision expected by late June or early July 2026.

Oral arguments last one hour, divided between the two sides. The government typically argues first. Each side has about thirty minutes, though most of that time is spent answering questions from the justices. The justices use oral arguments to test arguments, pose hypothetical questions, and probe for weaknesses.

When oral arguments occur, audio recordings are posted on the Supreme Court’s website and through various legal resource sites. You can listen live or download the audio afterward. Legal blogs like SCOTUSblog will provide accessible summaries of what happened in oral arguments.

After oral arguments conclude, the justices hold a private conference where they discuss the case and vote. The most senior justice in the majority assigns the opinion-writing task. The opinion-writing process typically takes months. The assigned justice drafts an opinion and circulates it to the other justices, who may suggest revisions or write concurring or dissenting opinions.

When the opinion is finally ready, the Court releases it on an “opinion day”—typically Mondays in June and July. The full text of the opinion, any concurring opinions, and any dissenting opinions are released simultaneously, available on the Supreme Court’s website.

When you read the opinion, look for several things. First, what is the specific holding—what did the Court decide? Is the ruling narrow or broad? Second, what is the reasoning? What principles did the Court rely on? Third, are there concurring opinions, and what do they reveal about divisions within the majority? Sometimes five justices agree on an outcome but disagree on reasoning—only the reasoning shared by five justices becomes “the law of the land.” Fourth, what do the dissenting opinions say?

In the birthright citizenship case, watch especially for how broadly the Court writes. If it narrows birthright citizenship, does it do so narrowly (applying only to undocumented and temporary visa holders), or does it rewrite the meaning of “subject to jurisdiction” more broadly? How much does the Court emphasize originalist reasoning? Are there concurring opinions suggesting some justices are uncomfortable with overturning precedent?

Resources for following this include the Supreme Court’s official website, SCOTUSblog, and major newspapers including the New York Times, Washington Post, and Wall Street Journal. Organizations like the Brennan Center for Justice, the ACLU, the Heritage Foundation, and the Cato Institute offer analysis from different ideological perspectives.

Implications for Other Constitutional Rights

If the Supreme Court narrows birthright citizenship, the immediate effect would be that certain children born in the United States wouldn’t automatically become citizens. But the case’s significance extends far beyond citizenship itself.

The equal protection clause protects “persons” and guarantees them “equal protection of the laws.” Under current doctrine, this protects all persons within a state’s jurisdiction—including non-citizens—from racial and gender discrimination.

If “jurisdiction” in the citizenship clause is read narrowly, could “within its jurisdiction” in the equal protection clause also be read narrowly? The language is the same in both places, and originalist methodology typically reads the same language consistently.

Similarly, the due process clause protects “persons” from deprivation of “life, liberty, or property” without due process. If “subject to jurisdiction” excludes certain children from citizenship, does it also mean those individuals have fewer due process protections?

Beyond the 14th Amendment, the case might affect how the Court interprets other constitutional provisions using broad language. The First Amendment protects “freedom of speech.” The Fourth Amendment protects against “unreasonable searches.” None of these provisions specify the scope of people they protect or what counts as a violation.

If the Court demonstrates that it will use originalist methodology to narrow the meaning of broadly worded provisions—reading “subject to jurisdiction” narrowly despite broad historical usage and 127 years of precedent—it signals that other broad constitutional language will also be narrowed.

What’s at Stake

The birthright citizenship case might seem to be about a narrow legal question: whether children born in the United States to parents without citizenship or green cards automatically become citizens. Understanding the case fully requires recognizing that it’s about something broader.

It’s about how the Supreme Court will interpret the Constitution itself—what it means to read the Constitution as having a fixed, original meaning that constrains judges, or as having meaning that evolves with contemporary understanding. It’s about whether precedent deserves respect even when a new judicial majority believes the prior decision was wrongly reasoned. It’s about what it means to be subject to a government’s laws and authority, and what rights that relationship creates.

The 14th Amendment emerged from the Civil War and Reconstruction, born of a determination to correct the catastrophic failure of the original Constitution—a failure made most evident by Dred Scott’s denial that Black people could ever be citizens. The amendment was designed to repudiate that ruling and to establish that people of color, former slaves and their children, were entitled to citizenship and all its attendant rights.

For 127 years, Wong Kim Ark has stood as the authoritative interpretation: that birth on American soil, combined with subjection to American law and jurisdiction, is sufficient for citizenship, regardless of parents’ status.

Now the Supreme Court will reconsider whether that interpretation is correct. The case raises genuine questions about what the original public meaning of “subject to the jurisdiction thereof” was in 1868. It raises questions about whether precedent should be overturned when a new majority believes it was wrongly reasoned. It raises practical questions about statelessness. And it raises questions about whether the Constitution has a fixed meaning that constrains judges or a meaning that must evolve as circumstances change.

Spring 2026 will be worth watching closely.
