Washington, D.C. — In a high-stakes legal battle with sweeping national implications, the Supreme Court is poised to rule on whether federal judges can block executive orders nationwide, stemming from President Donald Trump’s controversial attempt to end birthright citizenship.

While the case won’t directly decide if the 14th Amendment protects citizenship for children of undocumented immigrants, it could determine the future reach of nationwide injunctions—an essential legal tool that has frequently checked Trump’s executive authority.
What Is the Case Really About?
On his first day back in office, Trump signed an executive order to end birthright citizenship for children born in the U.S. to undocumented immigrants. Federal judges in Maryland, Massachusetts, and Washington State immediately blocked the order via nationwide injunctions, calling it “blatantly unconstitutional.”

The Trump administration appealed, claiming lower courts had overstepped their powers. The BBC reports that roughly 40 such injunctions have halted Trump policies this year alone.
The core legal question: can a single federal judge block a presidential order from taking effect nationwide?
The Argument Against Nationwide Injunctions
Critics—including both liberal and conservative Supreme Court justices—argue that nationwide injunctions grant too much power to single district judges. They also open the door to “forum shopping,” where plaintiffs file lawsuits in sympathetic jurisdictions to get favorable rulings.
Justice Clarence Thomas has described such injunctions as “legally and historically dubious,” while Justice Elena Kagan questioned whether a single judge should be able to stop a nationwide policy “for years.”
The Trump administration contends that these sweeping injunctions undermine the executive branch and delay lawful policymaking.
The Argument in Favor
Proponents say injunctions are necessary to maintain the rule of law, especially when executive orders bypass the legislative process. Without nationwide injunctions, people harmed by such orders would be forced to file lawsuits individually—an unfair and inefficient burden.

Justice Ketanji Brown Jackson sharply criticized the administration’s position, suggesting it encouraged a “catch me if you can” system. “You get to keep doing it until every affected person figures out how to sue,” she said during hearings.
Backers of nationwide injunctions argue they also ensure consistent application of federal laws across states, particularly in areas as critical as citizenship.
Birthright Citizenship and the 14th Amendment
The 14th Amendment guarantees citizenship to “all persons born or naturalized in the United States, and subject to the jurisdiction thereof.”
Trump’s legal team argues that the clause “subject to the jurisdiction thereof” excludes the children of undocumented immigrants. However, most constitutional scholars agree that the president cannot unilaterally override the amendment with an executive order.

During oral arguments in May, Justice Kagan noted that the administration had lost every lower court case on the citizenship issue, asking: “Why would you ever take this case to us?”
Possible Outcomes
The court could issue a narrow ruling, limiting nationwide injunctions to apply only to plaintiffs or their class-action equivalents. Alternatively, it might permit injunctions only on constitutional grounds or limit their geographic scope to the issuing judge’s district.
If the justices rule against injunctions, Trump’s executive order could take effect—ending birthright citizenship for certain groups—while legal challenges proceed. A broader ruling could undermine the judiciary’s ability to block federal policies with immediate national impact.

Should the court uphold the injunctions, the order remains blocked until it possibly returns to the Supreme Court in a future hearing specifically on the constitutionality of birthright citizenship.
What’s at Stake?
This decision could reshape the balance of power between the judiciary and the executive branch. It may also determine how quickly and broadly controversial policies like Trump’s immigration agenda can be implemented.
As the nation awaits the ruling, legal scholars stress that the case is not just about one policy, but about who holds ultimate authority in defining the boundaries of American democracy.
