Supreme Court to Weigh Trump’s Mandatory Immigration Detention Policy
The Supreme Court will decide whether the government can automatically keep certain immigrants in jail while their deportation cases continue.
Under the policy, these people do not get a hearing to ask for release on bond.
Their cases can last for months or even years.
The Department of Homeland Security announced the policy in July 2025.
It changed how the government had interpreted the law for nearly 30 years.
Several appeals courts have disagreed about whether the policy is legal.
The case began after Ricardo Aparecido Barbosa da Cunha was detained in Massachusetts.
He was initially denied a bond hearing but was later released on bond.
The Supreme Court’s decision could resolve the disagreement among the appeals courts.
The Supreme Court agreed to hear a challenge to the Trump administration’s mandatory detention policy.
The policy requires many immigrants in the United States illegally to remain detained without bond hearings during deportation proceedings.
The Department of Homeland Security issued the disputed guidance in July 2025, reversing a nearly three-decade-old interpretation.
Federal appeals courts are divided, with the 5th Circuit supporting the policy and the 2nd and 6th Circuits ruling against it.
The case involves Ricardo Aparecido Barbosa da Cunha, a Brazilian national who was arrested in Massachusetts and later released on bond.

Mandatory detention
Policy challengers
The 2nd and 6th Circuits ruled against automatically detaining immigrants without bond hearings, and migrants and advocacy groups have challenged the policy in numerous lawsuits.
Trump administration
The administration argues that federal law gives it authority to use mandatory detention, even though earlier administrations generally allowed some immigrants already living in the country to seek release on bond.
Legal interpretation
Policy challengers
Opponents rely on the longstanding interpretation under which immigrants already living in the United States could be released on bond while their immigration cases proceeded.
Trump administration
The 5th Circuit said prior administrations’ decisions not to use mandatory detention did not mean they lacked the authority to do so.
