Supreme Court Takes Up Trump Administration’s Mandatory Detention Policy
By Drooid · · How we work
Core Event
On October 1, 2026 the U.S. Supreme Court granted certiorari in *Rhoney v. Barbosa da Cunha*, agreeing to review the Trump administration’s policy that mandates detention of non-citizens facing removal without a bond hearing. The case centers on Ricardo Aparecido Barbosa da Cunha, a Brazilian national who entered the United States illegally around 2004, was arrested in September 2025, and was denied a bond hearing under the policy. Lower courts are split on whether the 1996 immigration statute applies only to migrants apprehended at the border or to anyone “seeking admission” inside the country.
Background & Context
In July 2025 the Department of Homeland Security issued guidance extending mandatory detention to all undocumented immigrants, overturning a three-decade-old interpretation that allowed release on bond for long-term residents. The policy is part of President Donald Trump’s broader “mass deportation” agenda pursued since his return to office in 2025. Since then, immigration courts have seen an “avalanche” of habeas petitions; a Reuters analysis reported more than 4,400 district-court rulings finding the policy unlawful, while the administration cites a need to prevent “perverse incentives” for illegal entry.
Data & Statistics
- Detention figures: Immigration and Customs Enforcement (ICE) reported 46,000 removals in July 2026, surpassing 43,000 in June; CBS noted more than 65,000 people held in detention during the summer.
- Litigation volume: Immigrants have filed over 73,000 immigration-court cases this year, about a quarter of all civil suits in federal court.
- Court outcomes: Nine of eleven federal appellate courts have ruled the policy exceeds statutory authority; the 5th and 8th Circuits have upheld it.
Official Statements & Responses
Criticism & Opposition
- Judge Lara Montecalvo emphasized that Congress has long implemented the disputed statutes, implying the administration’s reading is a “radical break from the past.”
Conflicting Reports & Gaps
- Detention totals vary: CBS cites “more than 65,000” detainees, while the New York Post estimates “about 70,000.”
- Number of lawsuits differs between sources: US News reports “more than 73,000” cases this year, whereas other outlets reference “over 20,000” lower-court rulings. The precise count of pending habeas petitions remains unclear.
Verbatim Quotes
- “Immigration enforcement should not depend on geographical happenstance,” — Solicitor General John Sauer
- “Moreover, the volume of habeas litigation will continue to impose immense burdens on district courts and U.S. Attorney’s Offices throughout the nation until this issue is resolved,” — Solicitor General John Sauer
- “If Congress meant to achieve such a radical break from the past, it would not have done so in such an indirect and ambiguous way,” — Joseph Bianco, US circuit judge

What’s Next
The Court’s new term begins on October 5, 2026. Oral arguments in *Rhoney v. Barbosa da Cunha* are expected in early 2027, with a decision projected for the summer of that year. The outcome will determine whether the mandatory-detention rule remains in force nationwide or is struck down as exceeding congressional authority.
