Supreme Court will hear Trump’s mandatory immigration detention policy

The Supreme Court agreed Thursday to decide whether the Trump administration can hold people who are in the United States illegally in detention without a bond hearing for the full length of their deportation cases.

The policy: In July 2025, the Department of Homeland Security told immigration officers that people in the country illegally are subject to mandatory detention without bond while removal cases run. That reversed a nearly three-decade practice of allowing many longtime residents a chance at release on bond, Reuters said.

Why courts split: Most federal appeals courts that have reviewed the policy have rejected it. The New Orleans-based 5th Circuit sided with the administration in February. Judge Edith Jones wrote that earlier presidents’ restraint did not mean the government “lacked the authority to do more,” Reuters reported. CBS said two circuits have allowed the no-bond approach and nine have required bond hearings or release for some detainees.

Who is affected: Immigrants and advocacy groups have filed tens of thousands of challenges. A Reuters analysis earlier this year found hundreds of judges had ruled more than 4,400 times that such detentions were unlawful. Politico put lower-court rejections above 20,000. ICE reported more than 46,000 people detained in July for alleged immigration offenses, CBS said.

The lead case: Ricardo Aparecido Barbosa da Cunha, a Brazilian national who entered illegally around 2004 or 2005, was arrested by immigration officers in September 2025 in Massachusetts while driving to work, Reuters said. He had a work permit after an asylum filing and no criminal conviction, according to CBS. After courts ordered a bond hearing, he was released. The 2nd Circuit later called the policy the “broadest mass-detention-without-bond mandate in our nation’s history.”

Grant of review, DHS July 2025 guidance, Barbosa da Cunha facts, 2nd Circuit ruling, and circuit split follow Reuters (John Kruzel), Oct 1, 2026, and CBS News (Melissa Quinn), Oct 1, 2026. Lower-court rejection counts and “blockbuster” framing also in Politico (Kyle Cheney) and The Hill. 5th Circuit Judge Edith Jones quotes from Reuters.
