Supreme Court Greenlights Border Turnbacks

USCIS documents and a green card on a table — BORDER POWER EXPANDS

The Supreme Court just handed the Trump administration a powerful new tool to stop asylum seekers at the border — before they ever set foot on U.S. soil.

At a Glance

The Supreme Court ruled 6-3 on June 25, 2026, that the government can legally turn back asylum seekers who are still standing on Mexican soil.
Justice Samuel Alito wrote for the majority that a person has not “arrived in” the United States until they physically cross the border.
The ruling clears the way for the Trump administration to revive “metering,” a border control tool used to prevent overcrowding at ports of entry.
The three liberal justices dissented, with Justice Sonia Sotomayor reading her dissent aloud from the bench in a rare public protest.

What the Court Actually Decided

The Supreme Court ruled 6-3 in Mullin v. Al Otro Lado that federal law does not require the government to process asylum claims from people who have not yet entered the United States.

Justice Alito wrote that, in plain language, a person does not “arrive in” a place before they physically enter it. That simple reading of the law means asylum seekers waiting on the Mexican side of the border have no legal right to demand entry or a hearing.

The ruling also addressed a separate but related case. The Court ruled 6-3 that the Department of Homeland Security (DHS) has the authority to end Temporary Protected Status for roughly 300,000 Haitian and 6,000 Syrian immigrants living in the United States.

The Court found that DHS decisions on that status are not subject to court review, and it rejected the claim that ending those protections was racially discriminatory.

The “Metering” Policy Explained

Metering is a border management strategy that limits the number of people who can present themselves at a port of entry each day. It was first used under President Obama and then expanded during President Trump’s first term.

The previous administration ended it in 2021, and a federal appeals court later ruled the practice was unlawful in 2024. The Trump administration asked the Supreme Court to overturn that appeals court ruling — and the Court agreed. ^[7]

The ruling does not automatically restart metering. The Trump administration must still take formal steps to reinstate the policy. But the Court’s decision removes the biggest legal roadblock that had been blocking it. ^[12]

If the administration moves forward, border officers could turn people away at ports of entry without any formal asylum screening, as long as those individuals have not yet set foot on U.S. soil.

Why This Matters for Border Security

The Trump administration argued in court that without metering, the executive branch loses a critical tool for managing border surges and preventing dangerous overcrowding at ports of entry. ^[3]

That argument won the day. For years, border communities and law enforcement officials have warned that uncontrolled surges strain resources, create safety risks, and slow down the entire immigration system. This ruling gives the administration real authority to manage those situations.

The left’s reaction was swift and predictable. Justice Sotomayor, joined by Justices Elena Kagan and Ketanji Brown Jackson, read her dissent aloud from the bench — a rare and dramatic move.

She argued that speaking with a Border Patrol agent at a port of entry is itself the first step in “arriving” in the United States. ^[3]

Advocacy groups called the ruling “devastating” and claimed it overturns over a century of immigration law. But the majority’s reasoning is grounded in the plain text of the statute, not activist interpretations layered on top of it.

Two Big Wins, One Clear Message

Taken together, the two June 25 rulings send a clear message: the Supreme Court’s conservative majority is willing to back the executive branch’s authority to manage immigration within the bounds of the law.

The administration now has legal cover to limit who can claim asylum at the border and to end temporary protections for large groups of foreign nationals. Both decisions were decided 6-3, straight down ideological lines. ^[2]

For Americans who have watched years of open-border policies flood communities with illegal crossings, strain public services, and drive up costs, these rulings represent a meaningful course correction.

The federal government has a duty to control who enters the country. The Supreme Court just confirmed that duty is real — and enforceable.
