Federal Appeals Court Rejects ICE Mandatory Detention Policy as Supreme Court Fight Looms
A growing legal battle over the Trump administration’s immigration detention policy is moving closer to the Supreme Court after another federal appeals court rejected an effort by Immigration and Customs Enforcement to detain large numbers of immigrants without allowing them to seek release on bond.
The latest decision adds to a series of defeats for the administration in federal appellate courts and intensifies a dispute over how the government interprets decades-old immigration law. At the center of the controversy is whether ICE can treat immigrants who are already living inside the United States as people seeking admission and therefore subject them to mandatory detention without a bond hearing.
The issue has become one of the most consequential legal questions surrounding the administration’s broader deportation campaign.
Appeals courts challenge ICE detention policy
The Fourth Circuit Court of Appeals ruled against the administration in a 2-1 decision on September 10, adding another appellate setback for ICE. The court rejected the government’s interpretation of federal immigration law and questioned whether Congress actually authorized such a sweeping expansion of detention without bond.
The decision followed similar rulings in other federal appellate courts. Reporting on the Fourth Circuit case described it as the ninth appellate loss for ICE on the issue. The growing number of rulings has created increasing pressure for the Supreme Court to settle the disagreement.
The Fourth Circuit majority said the government’s interpretation would result in an exceptionally broad system of mandatory detention. Judge Nicole Berner, joined by Judge Barbara Keenan, warned that mass detention without meaningful access to a hearing raised serious due-process concerns.
The administration, however, maintains that federal immigration law gives it broad authority to detain people who are subject to removal proceedings.
What mandatory detention means
The dispute centers largely on the difference between two immigration detention systems.
Under one provision of federal law, certain immigrants may be detained while their removal cases are pending but can potentially ask an immigration judge for a bond hearing. Under another provision, detention is mandatory for specified categories of noncitizens, meaning they generally cannot obtain release through a conventional bond proceeding.
ICE’s current interpretation seeks to place a much broader group into the second category.
The administration argues that people who entered the country without authorization can be treated as applicants for admission even if they have subsequently lived in the United States for many years. That interpretation would allow ICE to detain them without first giving them an opportunity to request bond.
Several courts have rejected that reasoning, concluding that the government’s interpretation stretches immigration statutes beyond their traditional meaning.
Dispute reaches immigrants with deep US ties
The policy has affected people who have lived in the United States for years or even decades.
Many of those caught by the policy have established families, jobs and communities in the country. Attorneys representing detainees have argued that people with substantial ties to the United States should not automatically lose the opportunity to ask an immigration judge for release.
The government takes a different position, maintaining that Congress provided mandatory detention authority and that ICE is obligated to enforce the immigration laws as written.
The disagreement has generated thousands of emergency cases in federal courts. Judges have been asked to determine whether individual detainees were lawfully placed into mandatory detention and whether constitutional due-process protections require access to a bond hearing.
Supreme Court increasingly likely to decide
The legal conflict has already reached the Supreme Court in related immigration detention litigation.
One major case, Genalo v. Black, concerns whether there is a point at which prolonged detention under a mandatory-detention provision requires an individualized bond hearing. Supreme Court records show that the justices granted review in June 2026.
The case demonstrates that the Supreme Court is already confronting questions surrounding the limits of mandatory immigration detention.
However, the legal issues are not identical. The current appellate dispute largely concerns whether the administration can place broad categories of people living inside the country into mandatory detention in the first place, while other litigation examines how long mandatory detention can continue before constitutional protections require an individualized hearing.
That distinction could become important if the broader ICE policy reaches the justices.
Earlier Supreme Court precedent
The administration’s position also relies on earlier Supreme Court decisions concerning immigration detention.
In Demore v. Kim, decided in 2003, the court upheld mandatory detention for certain noncitizens facing removal proceedings. The decision recognized the government’s authority to detain people in specified circumstances while their immigration cases were being resolved.
But later litigation has focused on the limits of that authority, particularly when detention becomes unusually lengthy.
The Supreme Court’s 2018 decision in Jennings v. Rodriguez also addressed statutory questions surrounding bond hearings for certain detained immigrants. Courts since then have continued to wrestle with how constitutional due process applies to prolonged detention.
Those precedents provide the legal background for the current dispute but do not automatically resolve the administration’s newer interpretation of who can be placed into mandatory detention.
Administration defends its approach
The Department of Homeland Security and the Justice Department have continued to defend ICE’s position.
The administration argues that immigration enforcement requires the ability to detain people who are subject to removal and that courts should not substitute their interpretation of immigration policy for that of Congress and the executive branch.
Supporters of the policy also point to the administration’s broader mandate to increase immigration enforcement and deportations.
The government has therefore continued defending its interpretation even as appellate courts have repeatedly disagreed with it.
The disagreement has produced an unusual legal landscape in which the practical consequences of the policy can depend heavily on where an immigrant is detained and which federal court has jurisdiction over the case.
Constitutional questions remain
Beyond the statutory dispute, the cases raise fundamental questions about due process.
Immigration detention is civil rather than criminal in nature, but it can nevertheless result in prolonged confinement while a person waits for a decision in removal proceedings.
Courts have therefore been examining whether mandatory detention can continue indefinitely without an individualized assessment of whether continued confinement is justified.
Recent court filings show the issue remains active across the federal judiciary. In related cases, courts have considered whether prolonged detention under Section 1226(c) can continue without a bond hearing when removal proceedings become unreasonably lengthy.
The Supreme Court’s eventual decisions could establish clearer nationwide rules.
A major test for Trump’s immigration agenda
The detention fight is closely connected to President Donald Trump’s broader immigration enforcement strategy.
The administration has expanded ICE operations and sought greater detention capacity as it pursues its deportation goals. Congress also significantly increased funding for immigration enforcement and detention in 2025, providing resources for a much larger detention system.
Whether that expanded infrastructure can be used under the administration’s interpretation of mandatory detention remains a major legal question.
For now, the appellate decisions have created substantial obstacles for ICE. The government can continue seeking Supreme Court review and defending its interpretation in individual cases, while immigrants and their attorneys continue challenging detention through federal courts.
The next stage could therefore bring the dispute directly before the nation’s highest court.
Until the Supreme Court issues a definitive ruling on the broader question, the legal status of ICE’s mandatory-detention policy will remain contested, with courts continuing to determine how federal immigration law applies to people already living inside the United States.
