WASHINGTON — A rare public exchange between Supreme Court Justices Samuel Alito and Sonia Sotomayor unfolded Thursday after the court handed the Trump administration a major victory on border enforcement, exposing unusually visible tensions between members of the nation’s highest court.
The confrontation came moments after the Supreme Court, in a 6-3 decision, upheld the administration’s authority to turn away migrants at the southern border before they enter the United States to seek asylum. The ruling centered on the legality of the long-disputed “metering” policy, which limits when asylum seekers may present their claims at ports of entry.
Sotomayor delivers rare dissent from the bench
After Justice Alito summarized the majority opinion in Mullin v. Al Otro Lado, Justice Sotomayor took the unusual step of reading portions of her dissent aloud in open court.
Reading a dissent from the bench is relatively uncommon and is typically reserved for cases a justice believes carry exceptional legal or constitutional significance.
Sotomayor called the majority’s opinion “egregiously wrong” and argued the ruling would have severe humanitarian consequences.
“The consequences of today’s decision are predictable,” she wrote.
“More people will die.”
She argued that migrants fleeing persecution could now be forced to remain in dangerous conditions outside the United States because they would be denied the opportunity to seek asylum at ports of entry.
Alito responds
Alito appeared visibly frustrated as Sotomayor delivered her remarks.
After she finished speaking, the conservative justice briefly returned to the lectern.
He remarked that had he known Sotomayor intended to deliver her dissent from the bench, “there’s much more I would have added” to his own summary before encouraging observers to read the court’s written opinions in full.
The exchange represented one of the more public displays of disagreement among the justices in recent years. Although sharp disagreements frequently appear in written opinions, direct verbal back-and-forth during opinion announcements is uncommon.
What the court decided
The dispute centered on whether migrants waiting on the Mexican side of the border have legally “arrived in the United States” for purposes of federal asylum law.
Writing for the majority, Alito concluded they have not.
The court held that federal immigration law allows border officials to decline entry to migrants who have not physically entered the United States, permitting the administration to continue using the metering policy.
The policy originated during the Obama administration in limited form before being significantly expanded during President Donald Trump’s first term. It was later ended under President Joe Biden but returned following Trump’s return to office.
A major immigration victory
The ruling marks one of the Trump administration’s most significant immigration victories before the Supreme Court this term.
By overturning a lower-court ruling against the policy, the justices cleared the way for federal officials to continue restricting access to asylum processing until migrants physically enter U.S. territory.
Immigrant advocacy groups argued the policy effectively denies many asylum seekers protections guaranteed under federal law, while the administration maintained it is necessary to manage overwhelming numbers of migrants arriving at busy ports of entry.
Court tensions emerge
The courtroom exchange also highlighted growing ideological divisions on the Supreme Court as the justices conclude another consequential term featuring major decisions on immigration, executive authority and other politically charged issues.
Public disagreements during opinion announcements remain unusual, making Thursday’s exchange between Alito and Sotomayor stand out even amid a term marked by sharp legal divisions.
