The U.S. Supreme Court agreed Thursday to hear a major challenge to the Trump immigrant detention policy, setting up a nationwide ruling on whether certain noncitizens arrested inside the United States can be held without access to an ordinary bond hearing while their removal cases proceed. The case, Rhoney v. Barbosa da Cunha, will be heard during the court’s new term after the justices granted the government’s petition on Oct. 1.
The dispute focuses on a Department of Homeland Security interpretation adopted in 2025 that treats some immigrants who entered without inspection as “applicants for admission” subject to mandatory detention under federal law, even when they have lived in the country for years. The Supreme Court’s decision to take the case creates a path toward a single national rule after lower federal courts reached conflicting conclusions about the policy and the statutes that govern immigration custody.
Trump Immigrant Detention Policy Reaches Supreme Court
The new grant of review marks a significant procedural step beyond the court’s position earlier this week, when the justices were still considering whether to take the case. American News Brief previously reported that the Supreme Court was weighing the detention dispute as it prepared for the new term, but the court had not yet agreed to decide the issue.
The case involves Ricardo Aparecido Barbosa da Cunha, a Brazilian national who entered the United States without inspection around 2005 and later applied for asylum. According to the Second Circuit’s April opinion, immigration officers arrested him in September 2025, and the government initially treated him as subject to mandatory detention without bond under 8 U.S.C. § 1225(b)(2)(A).
A federal district court disagreed with the government’s interpretation and ordered either a bond hearing or release. An immigration judge later concluded that Barbosa da Cunha was not a flight risk or danger and ordered him released on bond, while the government continued to press its broader statutory argument on appeal.
What the Legal Fight Is About
The central question is whether Section 1225, which governs certain people seeking admission to the United States, applies to noncitizens who entered without inspection but were later arrested after living inside the country. The administration says the statute requires detention while removal proceedings are pending, while challengers argue that Section 1226 generally governs detention for people arrested in the interior and allows immigration judges to consider release on bond.
The Second Circuit sided with Barbosa da Cunha and concluded that Section 1226(a), not Section 1225(b)(2)(A), governed his detention. In denying rehearing, judges on that court said their reading followed the text, structure and history of the immigration statute, while dissenting judges and the administration maintained that the law supports broader mandatory detention authority.
The administration has argued that mandatory custody helps ensure that people appear for immigration proceedings and remain available for removal if a final order is issued. Opponents respond that bond hearings do not decide whether a person may remain in the United States, but instead allow an immigration judge to assess issues such as flight risk and danger while the separate immigration case continues.
Lower Courts Have Repeatedly Challenged the Policy
The litigation has expanded rapidly since DHS changed its detention approach. More than 73,000 immigration-related federal suits have been filed in 2026, and Reuters reported that hundreds of judges had ruled thousands of times against the administration’s mandatory-detention interpretation.
Most federal appellate courts to address the statutory question have ruled against the administration, although the government has prevailed in some jurisdictions or on related detention issues. That split has created different legal rules depending on where a person is detained, one of the reasons the Supreme Court is often asked to intervene in disputes over federal statutes.
The ACLU, which represents Barbosa da Cunha with other counsel, said after the grant that the policy is unlawful and subjects immigrants to detention for months or longer without a bond hearing. The organization’s Oct. 1 statement said the challengers will argue that the Immigration and Nationality Act does not authorize the administration’s interpretation.
Administration Says Congress Authorized Mandatory Detention
The Department of Homeland Security welcomed the Supreme Court’s decision to hear the case and said the administration was implementing the law as Congress intended. The government’s position is that people who entered without inspection remain applicants for admission for purposes of the detention statute, even when they are arrested years after entering the country.
That interpretation would give federal immigration officials significantly broader authority to hold certain noncitizens without individualized bond review while their cases are pending. Because removal proceedings can last months or years, the practical effect of the Supreme Court’s eventual ruling could be substantial for detention capacity, immigration-court practice and the number of people eligible to seek release.
What Happens Next
The Supreme Court has not yet ruled on the merits, and granting review does not indicate how the justices will decide the case. The court’s Oct. 1 order list simply states that certiorari was granted in docket No. 26-104, formally adding the dispute to the term.
Briefing from the government, Barbosa da Cunha and outside groups will shape the arguments before the justices, with oral argument expected during the term. The decision could clarify which detention statute governs a large category of noncitizens arrested inside the United States and whether access to bond hearings will depend on an individualized immigration judge’s assessment or on a broader mandatory-custody rule.
The case will also test how far an administration can go when adopting a new interpretation of a long-standing immigration statute that substantially changes detention practice. Whatever the outcome, the ruling is likely to become one of the Supreme Court’s most consequential immigration decisions of the 2026-27 term because it could establish a uniform national standard for detention while removal proceedings are underway.
