This editorial from Reason cuts through the noise of political posturing to deliver a rigorous historical autopsy of birthright citizenship. While much of the coverage focuses on the immediate political fallout, the piece argues that the Supreme Court's 6-3 decision was less about modern immigration policy and more about honoring the specific intent of the Fourteenth Amendment: ensuring that freed slaves could never again be denied their status as citizens. It is a stark reminder that legal theories which sound abstract today were forged in the fires of slavery, and ignoring that history risks unraveling the very foundation of American citizenship.
The Jurisdictional Trap
The core of the article's strength lies in its dismantling of the administration's claim that children of undocumented immigrants are not "subject to the jurisdiction" of the United States. Reason reports that for decades, the dominant interpretation held that this phrase simply covers all children of parents required to obey U.S. law. The piece argues that the majority opinion correctly traces this rule back to British traditions and early American jurisprudence, noting that in 1868, "jurisdiction" referred to the "[p]ower of governing or legislating."
This historical grounding is crucial because it exposes the fragility of the executive branch's position. By anchoring the definition in the ordinary legal meaning of the text at the time of ratification, the Court avoided a slippery slope where citizenship could be stripped based on the parents' visa status. The editors highlight that this scope was well settled by Schooner Exchange v. McFaddon, an 1812 case where Chief Justice Marshall explained that "jurisdiction" referred to "the full and complete power of a nation within its own territories."
To be "subject to" the jurisdiction of the United States, then, is to "liv[e] under" its "dominion," a meaning reinforced by the Clause's territorial focus on those born "in" the United States.
Critics of this view might argue that modern immigration complexities were unforeseeable in 1868, but the piece effectively counters this by pointing out that illegal entry was not a novel concept then—thousands of enslaved people were brought into the U.S. illegally after the slave trade ban in 1808.
The Domicile Paradox
The commentary takes a sharp turn when analyzing Justice Clarence Thomas's dissent, which attempts to exclude undocumented immigrants based on a lack of "domicile." Reason notes that this theory creates an impossible historical contradiction: it would have denied citizenship to the very people the Fourteenth Amendment was designed to protect. The piece argues that if illegal entry negates domicile, then slaves brought in illegally after 1808 were never citizens, a conclusion that directly undermines the Citizenship Clause's primary objective.
The editors point out the logical flaw in Thomas's reasoning regarding voluntary residence. They note that while undocumented migrants often choose to stay, enslaved people had no "intention of remaining" and would have preferred return to their homelands. Yet, under a strict domicile theory requiring voluntary intent, slaves would fail the test even more than modern migrants. The article emphasizes that in 1890, the Supreme Court ruled that "No length of residence, without the intention of remaining, constitutes domicile," yet this standard was never applied to deny citizenship to freed Black Americans.
If illegal entry is enough to vitiate domicile, these people and their descendants would not - under Thomas's approach - be entitled to birthright citizenship.
A counterargument worth considering is whether "domicile" should be redefined for a modern nation-state with porous borders. However, the piece suggests that such a redefinition ignores the constitutional imperative of the 14th Amendment, which was explicitly written to prevent exactly this kind of exclusionary logic.
Allegiance and Protection
The final major thrust of the editorial addresses Justice Alito's dissent, which posits that citizenship requires an "allegiance solely" to the United States. Reason reports that this theory collapses when applied to the historical context of slavery, as captured Africans owed allegiance to their homelands just as much as modern migrants might. The editors argue that the administration's attempt to link citizenship to a "social compact" or an exchange of allegiance for protection fails because enslaved people were explicitly excluded from any such compact by the government itself.
The piece highlights the irony that while undocumented immigrants face deportation, they still receive more legal protection than slaves did, who were subject to brutal oppression facilitated by state and federal authorities. The editors note that even temporary visa holders can seek law enforcement protection without fear of immediate deportation, a safeguard that was nonexistent for Black Americans in the 19th century.
Far from protecting them, state and federal governments facilitated their brutal oppression at the hands of their masters.
This section effectively reframes the debate from "allegiance" to "protection," suggesting that the administration's argument is not just legally unsound but historically insensitive to the legacy of the 14th Amendment. The editors also touch on Justice Kavanaugh's concurrence, which suggests the executive order was illegal under a 1940 statute rather than the Constitution itself, arguing this misses the point that the Citizenship Clause was intended to cover those illegally present in the country.
Bottom Line
The strongest part of Reason's analysis is its unwavering focus on the historical purpose of the Fourteenth Amendment as a shield against racial exclusion, proving that modern arguments for stripping birthright citizenship inevitably fail when tested against the reality of slavery. Its biggest vulnerability lies in assuming that all legal scholars will accept this historical parallel without resistance from originalist interpreters who prioritize textualism over intent. The reader should watch how lower courts apply this precedent to future challenges involving national security or emergency border closures, where the definition of "jurisdiction" may be tested again.
