Supreme Court Rules 6-3 That Asylum Seekers Stopped at the Border Have Not 'Arrived' in the U.S., Reversing Ninth Circuit in Mullin v. Al Otro Lado
The June 25, 2026 merits decision held that federal asylum law is triggered only when a person physically crosses the border, clearing the legal path for the 'metering' practice that caps daily asylum processing at ports of entry.
Standing on the Bridge, Not the Line
For nearly six years, nothing about the practice was happening. U.S. border officers stopped formally "metering" asylum seekers at ports of entry back on November 1, 2021, when the acting head of Customs and Border Protection revoked it[10]. And yet on June 25, 2026, the Supreme Court spent a signed, fully argued opinion deciding whether that dead policy had been legal all along[1][14]. The administration pressed the case anyway, and won, 6-3[1]. That gap between what changed on paper and what changes at the border is the story underneath the story.
The case is Mullin v. Al Otro Lado, No. 25-5, argued March 24, 2026, and it turned on a single word: "arrives"[1]. Federal law says asylum is available to a person who "arrives in the United States." It also requires officers to inspect anyone who does[1]. The question was whether someone stopped on the Mexican side of a bridge, blocked by a U.S. officer before they can step onto U.S. pavement, counts as having arrived. The Court said no. Justice Samuel Alito wrote for the majority, joined by Chief Justice John Roberts and Justices Clarence Thomas, Neil Gorsuch, Brett Kavanaugh, and Amy Coney Barrett[1][14]. That reversed the Ninth Circuit, which in 2024 had agreed with a lower court that the practice was unlawful[15].
The Word That Decided Everything
"Metering" is the government's term. Its critics call it a "turnback"[3]. Either way, the mechanism is simple. A port of entry can only process so many people a day — it has a fixed number of officers, inspection booths, and holding space. Once that day's slots fill up, officers position themselves at the edge of U.S. soil, often literally in the middle of an international bridge, and stop anyone else from crossing[10]. Those people wait in Mexico, sometimes for weeks, sometimes for months[3][9].
The legal fight was over who absorbs that bottleneck. If asylum rights only switch on at physical arrival, the government can hold the line wherever it chooses and the wait falls entirely on the person outside it. If the rights switch on earlier, at an attempt to enter, then Congress's inspection duty follows the person to wherever an officer meets them, and the government has to accommodate everyone who shows up[8][11]. The Court chose the first reading. Because it's a statutory ruling from the full Court, it applies nationwide and can't be reversed by a lower court or a future president alone. Only Congress or the Supreme Court itself could undo it[1].
Two Readings of the Same Sentence, Neither One Absurd
For the administration and its allies, this isn't really about asylum seekers at all — it's about who gets to interpret a sentence Congress wrote. Congress said "arrives." No statute says a person standing on the Mexican half of a bridge has arrived anywhere[1]. On this reading, lower courts had quietly rewritten the law to impose a duty Congress never wrote: an obligation to admit an unlimited number of people through a port each day, regardless of staffing[7]. Backers of the ruling also point out that metering delayed access rather than denying it outright — people kept their place in line and were processed as capacity opened up[3].
Sotomayor's dissent, joined by Justices Elena Kagan and Ketanji Brown Jackson, reads the same statute and sees something else: a detailed inspection and asylum system that Congress built after the Refugee Act of 1980, a law with roots in the aftermath of the Holocaust and World War II, now defeated by where an officer happens to plant his feet[8]. She wrote that the ruling "blesses the Executive Branch's decision to slam the door shut on all who are fleeing persecution, despite the detailed inspection and asylum system that Congress enacted and commands"[8]. She read the dissent aloud from the bench, an unusual step, and warned that "more people will die"[5][8]. Alito responded with an impromptu reply of his own from the bench — a rare exchange even by Supreme Court standards[12].
The Line Both Sides Actually Agree On
Here's the part that cuts across the divide instead of splitting it. Sotomayor argued the ruling creates "a perverse incentive to enter at an unlawful rather than a lawful location"[5]. That's the same warning the plaintiffs made in their own filings. If people can't get processed by waiting at a bridge, some of them will try crossing somewhere there's no bridge at all, no officer, and no line. Fox News's own news coverage led its story with that argument, not with the administration's win — an unusual choice for an outlet generally sympathetic to the ruling, and a sign of how sturdy that particular prediction is across the spectrum[5].
What nobody can say yet is whether it's actually happening. As of mid-August 2026, there's no confirmed report that CBP has restarted metering. Advocacy groups warn it now legally could[9]. That leaves the ruling in an odd position: a fully settled question of law sitting on top of a completely unsettled question of fact.
Whose Backyard the Waiting Happens In
Coverage from outside the U.S. tends to skip past the statutory argument almost entirely. Al Jazeera's reporting, filed when the Court first agreed to hear the case, spent most of its space on the people already waiting in Tijuana and Ciudad Juarez rather than on what "arrives" means in a federal code section[4]. That's not an oversight so much as a different vantage point. Whoever a U.S. officer turns back at a bridge doesn't disappear — they stay in a Mexican border city, where shelters, city budgets, and local police absorb the cost of a decision made entirely on the U.S. side of the line[4]. In earlier metering periods, thousands of people lived in makeshift camps along that border for weeks or months at a stretch, and advocates say those camps became targets for kidnapping and assault[3][8].
American coverage split more predictably along ideological lines, but rarely by disputing facts — mostly by choosing what to put in the headline. SCOTUSblog led with the holding itself and largely avoided adjectives[2]. Bloomberg Law's headline called the policy "defunct," which is true — it hasn't run since 2021 — but that framing quietly lowers the stakes of a ruling advocates call a live authorization[13]. National Review treated the case as a straightforward textual question and left the humanitarian record out of the analysis[6]. On the left, Common Dreams built its headline entirely around Sotomayor's most alarming line, without the majority's countervailing reasoning[8]. None of these outlets got the underlying facts wrong. They just decided which facts belonged in the first sentence.
What Happens at the Bridge Next
For now, the ruling changes the law but not, as far as anyone can confirm, the scene on the ground. The camps that formed under the old metering policy haven't reappeared, at least not yet, and Border Report notes advocacy groups are watching closely for signs that they might[9]. What the decision does is remove the legal obstacle that had stood in the way of restarting the practice, without itself flipping any switch[1][9]. Whether CBP flips that switch, and whether Sotomayor's prediction about crossings between ports comes true, are the two questions the ruling leaves open — and neither one has an answer yet.
Summary
On June 25, 2026, the Supreme Court ruled 6-3 that U.S. asylum law does not protect a person who is stopped at the border before setting foot on U.S. soil[1][2]. The case is Mullin v. Al Otro Lado, No. 25-5. Justice Samuel Alito wrote the majority opinion. The Court held that a person 'arrives in the United States' — the phrase that switches on the asylum and inspection rules — only by physically crossing the line[1]. That reversed the Ninth Circuit, which in 2024 had upheld a lower court's finding that the government's turnback practice was unlawful[15].
The practice at issue is called 'metering' by the government and 'turnbacks' by its critics. Border officers stand at the edge of a port of entry, often on the middle of an international bridge. Once the day's processing capacity is full, they stop additional people from stepping onto U.S. ground[10]. Those people wait in Mexico. Metering started in the last year of the Obama administration, was written into formal CBP guidance in 2018, and was revoked by the acting CBP commissioner on November 1, 2021[10].
The two sides disagree about what the case is really about. For the administration and its supporters, it is a question of statutory text and who controls the border line — Congress wrote 'arrives,' and judges cannot stretch that word to cover people who have not arrived[1][7]. For asylum advocates, it is about whether the right to ask for protection can be switched off by keeping someone a few feet away — Justice Sonia Sotomayor, dissenting with Justices Elena Kagan and Ketanji Brown Jackson, said the majority 'blesses the Executive Branch's decision to slam the door shut on all who are fleeing persecution'[8]. She read her dissent aloud from the bench and warned that 'more people will die'[8]. Alito then gave an unusual impromptu reply from the bench[12].
One widely shared point cuts across the divide. Sotomayor wrote that the ruling creates 'a perverse incentive to enter at an unlawful rather than a lawful location'[5]. That is the same argument the plaintiff group made, and Fox News's news coverage led with it[5]. As of mid-August 2026, there is no confirmed report that CBP has restarted metering; advocacy groups say it now legally could[9].
The Event
The Supreme Court issued its decision in Mullin v. Al Otro Lado, No. 25-5, on June 25, 2026, after argument on March 24, 2026[1][14]. By a 6-3 vote, it held that under the Immigration and Nationality Act a person 'arrives in the United States' for purposes of 8 U.S.C. §1158(a)(1) and §1225(a) only upon crossing the border, so the statute neither entitles a person standing in Mexico to apply for asylum nor requires an officer to inspect that person[1]. Justice Alito wrote the opinion, joined by Chief Justice John Roberts and Justices Clarence Thomas, Neil Gorsuch, Brett Kavanaugh and Amy Coney Barrett; Justice Sotomayor dissented, joined by Justices Kagan and Jackson, and read her dissent from the bench[1][8][14]. The judgment of the U.S. Court of Appeals for the Ninth Circuit was reversed and the case remanded[1][14].
Undisputed Facts
- The decision was a signed merits ruling on the Court's regular docket, not an emergency-docket order; it was argued March 24, 2026 and decided June 25, 2026[1][14].
- The vote was 6-3, with Justice Alito writing for the majority and Justice Sotomayor writing the dissent joined by Justices Kagan and Jackson[1][14].
- The holding turns on the phrase 'arrives in the United States' in 8 U.S.C. §1158(a)(1) and §1225(a); the Court read it to require physically crossing the border[1].
- The ruling reversed the Ninth Circuit, which in 2024 had affirmed a district court holding that the turnback practice was unlawful[15].
- 'Metering' means CBP officers position themselves at the limit line of a port of entry and stop people from stepping onto U.S. soil once daily processing capacity is reached[10].
- The practice began in the final year of the Obama administration, was formalized in a 2018 CBP memorandum, and was revoked by the acting CBP commissioner on November 1, 2021[10].
- Justice Sotomayor read her dissent from the bench, and Justice Alito responded from the bench — a rare exchange at the Court[8][12].
- Both the plaintiff group and Justice Sotomayor argued the ruling creates an incentive to cross between ports of entry rather than at them[5].
The Pressure
Strip away the moralizing and blame. What structural realities persist regardless of which narrative wins?
- Processing capacity is a real, physical limit
- A port of entry has a fixed number of officers, inspection lanes and holding cells. Whatever the law says, only so many people can be processed in a day. Metering is one answer to that limit; long crowds on the bridge are the other. The legal fight decides who bears the cost of the bottleneck — the U.S. government or the person waiting in Mexico[10].
- The word does the work
- Everything turned on one verb. Congress wrote that asylum is available to a person who 'arrives in the United States'[1]. Neither side disputes the sentence; they dispute whether standing on the Mexican half of a bridge, blocked by a U.S. officer, counts as arriving. A statutory holding like this one is durable — only Congress or the Court itself can change it.
- Litigation over a policy nobody is currently running
- Metering was revoked on November 1, 2021 and, as of mid-August 2026, no restart has been confirmed[9][10]. The administration pressed the case anyway. The value it won is the legal foundation, not an immediate operational change — which is why one outlet could accurately call the policy 'defunct' while advocates accurately called the ruling consequential.
Material realityThe decision reverses the Ninth Circuit and settles a statutory question nationwide: U.S. asylum and inspection duties begin at physical entry, not at an attempt to enter[1][15]. That does not itself restart metering. It removes the court order that had stood in the way[9]. If CBP does restart it, the observable effects would be the ones seen in 2018-2021: waiting lists at bridges in Tijuana, Ciudad Juárez and Matamoros; people living in makeshift shelters for weeks or months; and, both the plaintiffs and the dissenting justices predict, more crossings between ports rather than at them[3][5][8]. Whether that last prediction holds is the empirical question the ruling now sets up, and it is not yet answerable.
Narrative as a weaponThree groups are actively shaping how this reads. The administration and right-leaning legal commentators want you to see a court correcting judges who stretched a statute — the frame is text and separation of powers, and it works best if the border camps stay out of the picture[7]. Advocacy groups and progressive outlets want you to see a right switched off by geography, and they lead with the dissent's most alarming sentence — a frame that works best if the statutory argument stays thin[8]. A third, quieter frame comes from the legal trade press: the policy has not operated since 2021, so this is a ruling about future authority, not a change you can go photograph tomorrow[9]. One more thing worth naming: the story as it circulated in some assignment and aggregation feeds described an August 2026 emergency-docket order lifting a lower-court block. That is wrong. It was a fully argued merits decision issued June 25, 2026[1][14]. The emergency-docket label matters, because rulings on that docket are typically brief, unsigned and provisional — this one is none of those.
How Each Side Sees It
Each major actor’s view — how it frames things, its underlying incentive, and how it’s materially affected. Tap a side to read it.
Frames it asThe case is about who decides where the border line is, and about reading a statute as written. Congress used the word 'arrives.' A person standing on the Mexican half of a bridge has not arrived, and no act of Congress says otherwise[1]. On this view, lower courts had effectively rewritten asylum law to give the federal government a duty it never took on: an obligation to admit an unlimited number of people onto U.S. soil each day, no matter the staffing at the port[7]. Supporters also stress that metering is a capacity tool, not a ban. The Court's opinion notes that the earlier policy delayed rather than denied access to the asylum process — people kept their place and were processed as slots opened[3]. And they argue the alternative is worse: if officers cannot manage the flow at a bridge, crowding at ports becomes its own safety and security problem[7].
WhyRestoring executive control over the pace of asylum processing, and locking in a textual reading that limits judicial supervision of border operations[1][7]. Immigration enforcement is also a central promise to the administration's political base.
Impact on themThe administration won a durable legal foundation. Because this is a statutory holding by the full Court, it binds nationwide and can only be undone by Congress or by the Court itself[1]. As of mid-August 2026, no restart of metering has been confirmed[9].
Frames it asThe dispute is about whether a legal right can be defeated by geography. Congress built a detailed inspection and asylum system in §1225 and §1158, and it did so after the Refugee Act of 1980 — legislation Sotomayor's dissent tied to the moral reckoning that followed the Holocaust and World War II[8]. If an officer can stand a few feet forward and stop someone from touching U.S. ground, the whole system can be switched off at will, without Congress changing a word[8][11]. Their second argument is factual, not moral: metering does not reduce migration, it relocates it. People wait weeks or months in makeshift camps on the Mexican side, where cartels prey on them[3][9]. Their third argument is the one the majority's critics on the right also find hard to dismiss — blocking the lawful line pushes people to cross unlawfully between ports[5].
WhyPreserving access to the asylum process as a legal entitlement rather than an executive favor, and protecting clients already waiting in Mexican border cities[3][11].
Impact on themA direct loss. The Ninth Circuit judgment they had won was reversed and the case remanded[1]. Their remaining paths are narrower: claims under other statutes or treaties, state-level and humanitarian work, or legislation in Congress.
Frames it asTheir argument is about statutory structure, not sympathy. Section 1225 imposes an inspection duty on officers who encounter people seeking entry; reading 'arrives' to require completed physical entry, they say, lets the government evade that duty by controlling where its own officers stand[8][11]. Sotomayor's dissent says the majority 'blesses the Executive Branch's decision to slam the door shut on all who are fleeing persecution, despite the detailed inspection and asylum system that Congress enacted and commands'[8]. She warned from the bench that 'more people will die,' and argued the reading creates 'a perverse incentive to enter at an unlawful rather than a lawful location'[5][8].
WhyMarking the limits of the majority's reasoning for future cases, and building a record Congress could act on.
Impact on themDissents do not change the outcome. But a bench-read dissent is a signal to Congress and the public, and it drew Alito's rare same-day reply from the bench[12].
Frames it asCoverage from outside the U.S. frames the practical burden as falling south of the line: whoever is turned back does not disappear, they stay in Tijuana, Ciudad Juárez, Matamoros and Nogales[4]. Shelters, municipal budgets and local police absorb the cost of a U.S. processing decision made at a bridge. That is the crux from this vantage — not what §1158 means, but who houses the queue[4].
WhyLimiting a long-term population of stranded people, and keeping the issue tied to U.S.-Mexico negotiation rather than unilateral U.S. action[4].
Impact on themDirectly exposed if metering restarts. In earlier metering periods, thousands waited weeks or months in camps along Mexico's northern border[3][9]. No prominent Mexican government reaction to the ruling surfaced in the coverage reviewed.

| Fox News | U.S. right | 4 | 'Supreme Court asylum ruling could increase illegal crossings, critics say' — leads with the dissent's warning, not the win. | An unusual inversion: a right-leaning outlet's news desk hangs the story on a liberal justice's prediction that the ruling backfires.

| Al Jazeera | Qatari state-funded | 4 | 'US Supreme Court to weigh "metering" of asylum claims at US-Mexico border' — written at the cert stage, centered on people waiting in Mexico. | Scare quotes around 'metering' signal the government's term is a euphemism.
