Supreme Court Overturns Trump’s Birthright Citizenship Order
In a significant ruling, the Supreme Court has overturned a directive from President Trump regarding birthright citizenship, which aimed to deny this status to children born to undocumented immigrants and tourists. This marks the second time within six months that the court has rejected Trump’s signature policy.
The executive order, which Trump signed on his first day in office, faced legal challenges that questioned its legality. Critics argued that it violated the 14th Amendment, which clearly states that anyone born or naturalized in the U.S. is a citizen, as long as they are under U.S. jurisdiction.
Further solidifying this stance, the Immigration and Nationality Act of 1952 specifies that birthright citizenship is granted to individuals born in the U.S. who are under U.S. jurisdiction.
On April 1st, Trump became the first sitting president to attend oral arguments before the Supreme Court. Many observers believed that the administration’s chances of success were slim, with experts raising doubts over Trump’s ability to redefine birthright citizenship unilaterally via an executive order.
A pivotal case influencing this decision was United States v. Wong Kim Ark from 1898, which revolved around the citizenship status of a man born to Chinese immigrants. Despite the restrictions of the Chinese Exclusion Act, the Supreme Court ruled that nearly all children born in the U.S. are automatically citizens unless they belong to specific exceptions, such as descendants of foreign diplomats.
During the proceedings, Attorney General John Sauer contended that the Wong Kim Ark case involved legally residing immigrants, not undocumented individuals. He suggested that the reduced levels of immigration in the 1800s indicate that the present circumstances represent a national security concern under presidential authority.
Last year, the Supreme Court had limited the authority of lower courts to issue nationwide injunctions against presidential actions relating to birthright citizenship. However, they left room for lower courts to potentially block the president’s order in class action situations.
The case resolved by the Supreme Court was Trump v. Barbara, brought by three plaintiffs affected by the executive order.
Among the challengers was Barbara, a Honduran asylum seeker who gave birth last October. Another, Susan, is a Taiwanese national on a student visa who had a daughter in April 2025. At the time of the lawsuit, she was in the process of obtaining a U.S. passport for her newborn. The third, Mark, is a Brazilian applicant for permanent residency, whose child was born in March 2025 and initially received a U.S. passport.
All three participants filed their lawsuits under pseudonyms, claiming the executive order unlawfully deprived their children of U.S. citizenship and related benefits such as Social Security, Medicaid, and food assistance.
A federal judge in New Hampshire granted a preliminary injunction, designating the plaintiffs’ children and others in similar situations as a national class.
In a related context, Trump faced a setback earlier this year when the Supreme Court ruled against him in a separate case, limiting his use of the International Economic Emergency Powers Act to impose tariffs.
