The U.S. Supreme Court has agreed to review a contentious immigration policy implemented during the Trump administration that allows for the detention of millions of immigrants without the opportunity to seek bond, even if they have lived in the United States for years without criminal records. The court’s decision to take up the case on October 1 marks a significant test of the administration’s stringent approach to immigration enforcement.

The policy centers on a reinterpretation of a 1996 immigration statute that has traditionally been applied to individuals apprehended at or near the U.S. border. Under the Trump administration’s new interpretation, this mandatory detention can extend to immigrants arrested in communities across the country, where they previously could be eligible for release on bond if they demonstrated to a judge they posed no danger and would attend future immigration proceedings.

Opponents argue that this expanded detention policy represents a radical departure from established law and is designed to exert pressure on immigrants—many of whom have long-standing ties to the U.S., including pending citizenship applications or U.S.-born children—to leave voluntarily. The American Civil Liberties Union, which is defending affected immigrants, called the policy "a radical break with the law."

The government maintains that the policy is necessary to prevent undocumented immigrants from evading deportation. Then-Attorney General Pam Bondi stated that the law is clear and that previous administrations and courts had failed to enforce it properly. A divided federal appeals court in Missouri sided with the administration in March, a decision also supported by another appeals court. However, the policy has faced substantial resistance in the judiciary, with nine appeals courts ruling against it.

In August, a divided appeals court in Massachusetts underscored the longstanding interpretation of the statute, noting that five prior administrations had consistently allowed bond hearings for immigrants detained inland rather than mandating detention. Judge Lara Montecalvo wrote that immigrants detained by U.S. Immigration and Customs Enforcement (ICE) after living in the U.S. retain the right to bond hearings.

The Supreme Court’s ruling in this case has the potential to reshape immigration detention policy, potentially affecting millions of immigrants nationwide. This case is one of multiple immigration-related challenges before the court this term. Notably, the court will also hear arguments in December concerning whether the administration can deport immigrants to third countries without giving them a chance to demonstrate that they might face persecution or torture there.

Decisions on both cases are anticipated in 2027, and will likely have far-reaching implications for the country’s immigration enforcement framework.
