Justice Jackson Birthright Citizenship Opinion Rebukes Trump And Clarence Thomas Over ‘Babies Of Slaves’ Claim
Justice Ketanji Brown Jackson used her concurring opinion in Trump v. Barbara to deliver more than a legal response. She delivered a history lesson.
The U.S. Supreme Court ruled Tuesday that children born in the United States to parents who are undocumented or temporarily present are citizens at birth under the 14th Amendment, striking down President Donald Trump’s executive order that sought to narrow birthright citizenship. The decision rejected one of Trump’s signature immigration efforts from his second term and reaffirmed a constitutional guarantee that has stood since Reconstruction.
Chief Justice John Roberts wrote for the Court that “Citizenship, then and now, was the right to have rights,” adding that the framers of the 14th Amendment extended that promise to “every free-born person in this land.”
But Jackson, the first Black woman to serve on the Supreme Court, aimed her sharpest words at the Trump administration’s argument and Justice Clarence Thomas’ dissent. Both advanced the idea that the Citizenship Clause was intended only as a narrow protection for formerly enslaved Black Americans and their descendants.
Jackson Challenges A Narrow Reading Of Reconstruction
Trump has repeatedly claimed birthright citizenship was meant for the “babies of slaves,” not the children of immigrants. Jackson rejected that reading, writing that Thomas’ interpretation “bears little relationship to the history of its ratification.”
Supreme Court Justice Ketanji Brown Jackson also directly admonished fellow Justice Clarence Thomas for his dissent, accusing him of applying a “narrow vision” of the 14th Amendment in a 20-page concurring opinion.
“Despite his longstanding endorsement of a ‘colorblind’ Constitution, Justice Thomas now surprisingly suggests that the Citizenship Clause was a race-conscious remedial measure, relating only to ‘freed slaves such as Dred Scott,’” Jackson wrote.
Thomas, joined in dissent by Justices Samuel Alito and Neil Gorsuch, argued that the amendment — which grants automatic citizenship to those born in the United States — applies only to those “domiciled” in the country.
“Even worse,” Jackson wrote, “Justice Thomas’s telling elides the entire point of the Second Founding: The Reconstruction Amendments were an anticaste, antisubordination reset for the Nation, not a mere spot treatment for the dark stain of slavery.”
Her opinion traced the history of the Civil Rights Act of 1866, the 14th Amendment and the Reconstruction-era fight to define citizenship after the Supreme Court’s infamous Dred Scott v. Sandford decision. That 1857 ruling declared that people of African descent could not be citizens of the United States, a decision the 14th Amendment was designed to overturn. The conservative justice specifically referenced the Dred Scott decision, with Thomas arguing that the Court got that wrong because “Blacks were entitled to citizenship” as Americans.
Jackson argued that Black Americans were central to the fight for a broader and more universal understanding of citizenship, even when they were shut out of many formal political spaces.
“Black people who were generally not permitted at the polls or in the halls of power mobilized nevertheless to advance the universalist vision of belonging and citizenship that eventually won the day,” Jackson wrote.
Black Advocacy Helped Expand Citizenship For All
Jackson emphasized that formerly enslaved Black Americans did not fight for a citizenship rule that helped only themselves. Instead, she wrote, they pushed for a constitutional promise that would protect all people born on American soil.
“Freed Blacks did not advocate for a unique set of rules that catered only to their situation,” Jackson wrote. “Nor did they seek to advance their own position relative to, or at the expense and exclusion of, other marginalized groups.”
That point was central to her rebuke of Thomas. Jackson argued that the Reconstruction Amendments were designed to destroy caste-based citizenship, not create a bloodline rule that could later be used to exclude immigrants and their children.
Her concurrence also connected the fight for Black citizenship to later protections for other marginalized groups, including Chinese Americans. The Supreme Court’s 1898 decision in United States v. Wong Kim Ark affirmed birthright citizenship for a man born in San Francisco to Chinese parents, becoming one of the most important precedents in the citizenship debate.
Court Rejects Trump’s Birthright Citizenship Order
Trump’s executive order sought to deny automatic citizenship to children born in the United States if their parents were not citizens or lawful permanent residents. The administration argued those children were not fully “subject to the jurisdiction” of the United States under the 14th Amendment.
The Court rejected that argument. According to the opinion, children born in the United States to parents who are unlawfully or temporarily present are still “subject to the jurisdiction” of the country and are citizens at birth.
Justice Brett Kavanaugh agreed that Trump’s order should be blocked, but he did not fully join the constitutional reasoning. Justices Thomas, Samuel Alito and Neil Gorsuch dissented.
After the ruling, Trump criticized the decision and suggested Congress should act to end birthright citizenship legislatively. Legal scholars and civil rights advocates have long argued that changing birthright citizenship would require overcoming the plain text and history of the 14th Amendment.
Jackson Says The Constitution Rejects Caste
Jackson closed her opinion by warning against efforts to turn citizenship into a matter of ancestry, status or bloodline.
By ignoring the Constitution’s rejection of caste and subjugation, Jackson wrote, the Trump administration and Thomas denied the “clear, universalist vision” of the 14th Amendment’s framers.
That vision, she argued, was not simply about correcting one historic wrong. It was about rebuilding the nation after slavery on a broader promise of equality before the law.
“The America that was reborn from the rubble of the Civil War simply does not countenance that inequitable result,” Jackson wrote.
And in a final line that landed like a closing argument, Jackson said the majority had preserved “the most basic animating principle of our Nation’s founding—that all human beings are created equal—once more.”
For Jackson, the ruling was not just about immigration. It was about whether the country would honor the citizenship promise Black Americans helped force into the Constitution after the Civil War.
This time, the Court did.
