Why It Matters
A Supreme Court ruling on asylum policy could reshape how the federal government manages immigration at the southern border for years to come, with consequences extending to every state — including Idaho — that receives asylum-seekers and refugees through resettlement programs. The case centers on whether migrants who present themselves at official ports of entry while still on Mexican soil have the legal right to apply for asylum under U.S. law.
The outcome could determine whether the Trump administration gains a powerful new enforcement mechanism during future border surges, potentially limiting the number of asylum applicants processed nationwide and affecting refugee resettlement pipelines that serve communities across Idaho and the broader Mountain West.
What Happened
The U.S. Supreme Court heard oral arguments Tuesday, March 24, 2026, in a case examining the legality of a border management practice known as “metering,” which involves turning away asylum-seekers who have not fully crossed into the United States from Mexico.
The central legal question before the court is whether a migrant must physically enter U.S. territory to trigger the right to apply for asylum and be formally processed, or whether appearing at a port of entry — even from the Mexican side of the border — is sufficient under federal law.
Vivek Suri, assistant to the U.S. solicitor general, argued on behalf of the Trump administration that metering is a critical border management tool. “This is an important tool in the government’s toolbox for dealing with border surges when they occur,” Suri told the justices. “It’s not something the court should leave to future uncertainty.”
The metering policy itself is currently defunct, but the Trump administration is seeking a definitive ruling that could allow the practice to be revived in future situations involving high volumes of border crossings.
The Justices Weigh In
The court’s six conservative justices appeared sympathetic to the Trump administration’s position during oral arguments. Their questions focused largely on how to define the moment a migrant legally “arrives” in the United States — a definition that carries significant weight under U.S. asylum and refugee statutes.
The court’s three liberal justices — Sonia Sotomayor, Elena Kagan, and Ketanji Brown Jackson — pushed back, questioning whether the metering policy violated federal laws designed to protect refugees and asylum-seekers fleeing persecution. Justice Sotomayor and others probed the limits of executive authority when it comes to restricting access to the asylum process at official border crossings.
The ideological split on the bench suggests the conservative majority may ultimately side with the administration, though a formal opinion has not yet been issued.
By the Numbers
- Up to 680 migrants per day were turned away under the metering policy, according to a 2020 investigation by the Department of Homeland Security’s Office of Inspector General.
- The metering practice was first significantly expanded during the first Trump administration beginning in 2017.
- The Biden administration formally rescinded the policy in 2021.
- Multiple lower courts and federal appeals courts have blocked the metering policy on at least two separate occasions, finding it in conflict with U.S. asylum and refugee law.
- The Supreme Court is composed of six conservative and three liberal justices, reflecting a court balance established over the past decade.
Zoom Out
The metering case is one of several immigration-related disputes working through the federal court system as the Trump administration pushes to expand executive control over border policy. Similar legal battles have unfolded over Title 42 expulsions, the Remain in Mexico program, and restrictions on humanitarian parole — all of which have faced challenges in lower courts before reaching or nearing Supreme Court review.
States like Idaho, which has an established refugee resettlement infrastructure through organizations such as the International Rescue Committee in Boise, are directly affected by federal asylum policy. A significant restriction on who can apply for asylum at the border would reduce the overall number of cases entering the legal immigration pipeline, ultimately affecting resettlement volumes at the state level.
What’s Next
The Supreme Court is expected to issue a written opinion in the case before the end of its current term, which typically concludes in late June. A ruling in favor of the Trump administration would likely clear the legal path for the Department of Homeland Security to reinstate metering during future periods of elevated border crossings.
Immigrant advocacy groups have indicated they will pursue additional legal challenges if metering is revived. Congress could also act legislatively to clarify asylum access rights, though no specific legislation has advanced in either chamber as of this writing.
