The Fourth Circuit Court of Appeals has struck down the Trump administration's mandatory immigration detention policy in a 2-1 ruling that invoked the wartime internment of Japanese Americans, making it the ninth federal appeals court to reject the program and deepening a circuit split that now appears destined for the Supreme Court.
The decision, handed down this week, found that Immigration and Customs Enforcement cannot extend mandatory detention to immigrants living in the interior of the country without providing bond hearings. Two appeals courts have sided with the administration, creating the kind of direct conflict among circuits that the high court typically steps in to resolve.
At stake is a policy the Trump administration rolled out in July 2025: detain every migrant found anywhere in the United States whom ICE determines was not granted permission to enter. Before July, mandatory detention without bond hearings was generally reserved for individuals arrested at or near the border. The expansion turned that framework on its head, applying it to people already established in communities across the country.
The majority opinion, written by Judge Nicole Berner, did not hold back. The court held that the mandatory detention policy can apply to recent border arrivals but not to migrants determined to be living elsewhere in the country. That distinction sits at the core of the legal fight: whether "mandatory detention" under the Immigration and Nationality Act covers only those caught in the act of crossing or extends to anyone ICE encounters, regardless of how long they have lived in the U.S.
The majority then went further, drawing a historical comparison that drew sharp criticism from the administration. As Fox News reported, the court likened the policy to the internment of Japanese Americans during World War II.
"Mass detention of marginalized individuals without due process harkens back to some of the darkest moments in our country's history."
That language landed like a grenade in the ongoing political debate over immigration enforcement. A Department of Homeland Security spokesperson pushed back, telling Fox News that "the left and their activist proxies on the judiciary are resisting it so vigorously."
The Fourth Circuit ruling did not arrive in isolation. The Ninth Circuit issued its own 2-1 decision rejecting the same policy, and the composition of that panel made the outcome harder for the administration to dismiss as judicial activism.
Judge Daniel Bress, appointed by President Trump, joined the majority. His opinion grounded the ruling in statutory text and legislative history rather than sweeping moral language. As the Associated Press reported, Bress wrote for the panel.
"Although no reading of the complicated and interrelated textual provisions at issue here is without some shortcomings, the historical understanding of the statute is the better one."
That framing matters. When a president's own appointee reads the statute against the administration's position, it undercuts the narrative that opposition is purely partisan. The Ninth Circuit held that detained immigrants inside the United States cannot be denied a chance for release on bond.
DHS responded with a statement defending the policy on its merits: "President Donald Trump and Secretary Mullin are now enforcing the law as it was actually written to keep America safe."
The scorecard now stands at nine to two. Nine federal appeals courts have found ICE's mandatory detention expansion illegal. The Fifth and Eighth Circuits have upheld it. Politico's reporting on the growing conflict detailed how this split has accelerated over recent months, with court after court weighing in on the same statutory question and reaching opposite conclusions.
A circuit split of this magnitude is unusual. The Supreme Court grants review in a significant share of cases where two or more circuits disagree on a federal question. A nine-to-two divide makes the case for certiorari overwhelming by any standard measure.
The legal question at the center of the split is narrow but consequential. The Immigration and Nationality Act requires mandatory detention for certain categories of noncitizens. The administration reads the statute broadly, arguing it covers anyone ICE encounters who entered without authorization, no matter where or when. Opponents read it as limited to individuals caught at or near the border, with interior detainees entitled to bond hearings before an immigration judge.
For the tens of thousands of immigrants detained under the expanded policy since July 2025, the practical effect of these rulings is direct. In circuits that have struck down the policy, detained individuals can request bond hearings. An immigration judge then decides whether they pose a flight risk or a danger to the community. If neither, they can be released while their cases proceed.
In the Fifth and Eighth Circuits, the policy remains in effect. Immigrants detained in those jurisdictions have no right to a bond hearing under the administration's interpretation. That geographic patchwork is itself a problem the Supreme Court will likely want to resolve. Federal immigration law is supposed to operate uniformly, not shift based on which circuit a person happens to be detained in.
The administration has framed the policy as essential to its broader enforcement campaign. Without mandatory detention, officials argue, released immigrants often fail to appear for hearings. Civil liberties groups counter that bond hearings provide a constitutional check and that most immigrants do appear when released under supervision.
The Fourth Circuit's invocation of Japanese American internment drew the sharpest public reaction. Breitbart highlighted the comparison as central to the ruling's tone, noting that Judge Berner's majority opinion framed the detention expansion as part of a troubling historical pattern.
Critics of the comparison argue it is wildly disproportionate. Japanese American internment involved the mass imprisonment of U.S. citizens based solely on their ethnicity, authorized by executive order and later repudiated by Congress and the courts. The current policy targets noncitizens who entered without authorization, a legally and factually distinct category.
Supporters of the ruling see the comparison as a warning about unchecked executive power over vulnerable populations. Michael K.T. Tan of the ACLU's Immigrants' Rights Project told reporters that "the government's track record speaks for itself at this point," pointing to the lopsided tally of appellate losses.
Investigators and legal observers will need to watch several procedural markers. The administration can petition for rehearing en banc in any of the circuits that ruled against it, asking the full bench of judges to reconsider the panel decisions. That process could take months. Alternatively, the Solicitor General can file a petition for certiorari directly, asking the Supreme Court to take the case.
Given the depth of the split, the Court could act quickly. The Washington Examiner noted that the disagreement among circuits sets the stage for a possible Supreme Court showdown, and the current Court has shown willingness to take up major immigration questions on an expedited basis.
The justices would face the same statutory text that has divided the lower courts. Their reading will determine whether the administration can detain immigrants found anywhere in the country without bond hearings, or whether that power is limited to border encounters. The answer will shape immigration enforcement for years.
Authorities have not publicly confirmed how many individuals are currently held under the expanded policy or how many bond hearings have been requested in circuits where the policy has been blocked. Those numbers will matter when the justices weigh the real-world stakes.
The administration shows no sign of backing down. DHS has consistently maintained that the statute supports its reading and that the policy is critical to public safety. The nine appellate losses have not changed the agency's posture.
For now, the law means different things in different parts of the country. A person detained by ICE in Texas faces a different legal reality than one detained in Virginia or California. That patchwork is unstable by design. The Constitution's Supremacy Clause and the structure of federal immigration law both demand a single national rule.
Nine circuits say the administration got the law wrong. Two say it got the law right. One court will settle it.
When the Supreme Court takes this case, and the split all but guarantees it will, the decision will test whether executive enforcement power has limits that courts are willing to draw and hold.
