The Supreme Court heard arguments Tuesday over whether the Trump administration can revive "metering," an immigration enforcement policy that limits the number of people who can apply for asylum at ports of entry along the U.S.-Mexico border.
AP News reported that the case represents the Justice Department's push to overturn a lower-court ruling that declared the practice unconstitutional.
The stakes are straightforward. Can immigration authorities tell asylum seekers that a port of entry is at capacity and ask them to return another day? Or does federal law require the government to process every single person who shows up, regardless of operational realities on the ground?
If you think this sounds like common sense dressed up as a constitutional crisis, you're paying attention.
Metering was first used during the Obama administration, when large numbers of Haitians appeared at the main crossing to San Diego from Tijuana, Mexico. It was later expanded to all border crossings from Mexico during Trump's first term. Immigration authorities described the practice as necessary to handle an increase at the border.
The policy worked exactly as it sounds. When a port of entry reached capacity, officials told arriving migrants to come back when there was room to process them. Vivek Suri, an assistant to the solicitor general arguing for the administration, framed it plainly:
"It's saying our port is at capacity today, try again some other day."
That's not a rejection of asylum. It's a line. Every government agency on earth operates with capacity constraints. The DMV does it. Passport offices do it. But somehow, when it involves immigration enforcement, a federal judge decided it violated the Constitution.
The practice ended in 2020 when the coronavirus pandemic led the government to impose greater restrictions on asylum seekers. Then President Biden formally rescinded metering in 2021, a decision that fit neatly into his administration's broader posture of dismantling enforcement tools one by one.
Also in 2021, U.S. District Judge Cynthia Bashant, an Obama nominee, ruled that metering violated the migrants' constitutional rights and a federal law requiring officials to screen anyone who arrives at the border seeking asylum.
A divided 9th U.S. Circuit Court of Appeals affirmed her ruling, though nearly half of the judges on the full San Francisco-based appeals court voted to rehear the case.
Nearly half. That's not a court confident in its own reasoning. That's a court that barely held together.
Tuesday's arguments revealed a bench wrestling with the practical and legal dimensions of the case. Chief Justice John Roberts peppered an attorney for the migrants with questions on exactly where someone must be to claim asylum.
It's a deceptively important question: if the law requires screening anyone who "arrives at the border," does standing in a line that hasn't reached the processing window count as arriving?
Justice Brett Kavanaugh cut to the core incentive problem:
"Why would Congress privilege someone who illegally enters the United States?"
It's the question that the open-borders legal framework cannot answer honestly. If people who show up lawfully at a port of entry can be told to wait, but people who cross illegally between ports of entry trigger an immediate legal obligation, you have created a system that rewards lawbreaking. That's not a conservative talking point. It's a logical consequence of the lower court's ruling.
Justice Ketanji Brown Jackson, meanwhile, raised a procedural concern from the other direction:
"It just seems to me that we have a lot of hypotheticals regarding how this policy may have worked in the past, how it's possibly going to work in the future, but we don't have a policy in effect right now that we can actually rule on."
It's a fair procedural observation, but it also illustrates a familiar pattern. Courts block enforcement tools. Administrations rescind them under political pressure. Then when the next administration tries to restore them, opponents argue the case is moot because the policy isn't currently active. The legal fight becomes a game of keep-away.
The policy isn't in place now. Trump ordered a wider suspension of the asylum system at the start of his second term, and the Court is considering several immigration suits this term, including Trump's push to end birthright citizenship and efforts to strip certain legal protections for migrants.
But the metering case matters beyond its immediate application because it tests a fundamental principle: whether the executive branch has any authority to manage the flow of people at its own border.
When metering was in effect in 2019, the Associated Press found thousands of immigrants on waiting lists. People who were turned away settled in makeshift camps in Mexico. Advocates called this a humanitarian crisis. But the alternative, processing unlimited numbers regardless of capacity, is not humanitarianism. It's administrative collapse dressed up as compassion.
Rebecca Cassler, an attorney for the American Immigration Council, spoke after arguments:
"This life saving protection and more importantly, access to it is enshrined in our laws and has been for decades now."
Nobody disputes that asylum protections exist in federal law. The question is whether those protections require the government to have infinite processing capacity at all times or whether "come back tomorrow" is a reasonable operational response to a real-world constraint.
Cassler's framing collapses the distinction between denying asylum and managing a queue. They are not the same thing.
This case sits at the intersection of two competing visions of immigration law. One holds that the executive branch has broad authority to manage border operations, including the pace at which asylum claims are processed. The other holds that any friction in the asylum pipeline, even a temporary wait, constitutes a legal violation.
The second vision has dominated the lower courts for years, particularly in the 9th Circuit. It has produced a legal environment where enforcement tools used by administrations of both parties get struck down the moment a sympathetic plaintiff and a willing judge converge.
An Obama-era policy, upheld and expanded across three administrations, gets invalidated by an Obama-appointed judge. The circularity is almost elegant.
The Supreme Court now has the opportunity to inject some operational reality into asylum law. The government cannot process everyone simultaneously.
Telling someone to return tomorrow is not the same as slamming the door. And a legal framework that treats those two things as identical doesn't protect asylum seekers. It breaks the system for everyone.
The Court's decision will land in a term already heavy with immigration cases. How the justices rule here will signal whether the judiciary intends to let the executive branch enforce the border or continue second-guessing every tool it picks up.
