Second Circuit Blocks Trump Administration’s Mandatory Detention Policy

The Ruling: Mandatory Detention Declared Unlawful
On April 28, a three-judge panel of the U.S. Court of Appeals for the Second Circuit held that the Trump administration’s interpretation of the 1996 immigration statute—requiring mandatory detention without bond for most noncitizens—violates the statute’s text and raises constitutional concerns. The 3-0 opinion, written by Judge Joseph Bianco, applies to Connecticut, New York and Vermont.
Background and Policy Shift
The 1996 law permits mandatory detention for “applicants for admission,” limited to recent border crossers. ICE Director Todd Lyons re-interpreted the provision to treat any noncitizen subject to removal as an “applicant for admission,” and the Board of Immigration Appeals adopted the view in September, extending detention to long-term residents.
Key Players
Judge Joseph Bianco (Trump appointee), Judge José Cabranes (Clinton appointee) and Judge Alison Nathan (Biden appointee) sat on the panel. DHS and ICE defended the policy. ACLU attorney Michael Tan and the NYCLU represented Brazilian national Ricardo Barbosa da Cunha, whose habeas petition was central.
Data Snapshot
About 60,000 people are detained, 70 % without criminal convictions. Over 90 % of district judges have ruled for bond seekers. Politico counted 420 judges rejecting the policy versus 47 supporting it. The Fifth and Eighth Circuits have upheld it, creating a three-circuit split.
Implications
The court warned the policy would “strain our already overcrowded detention infrastructure, incarcerating millions, separating families, and disrupting communities.” The decision raises due-process concerns and may prompt Supreme Court review.
Official Statements
DHS said the administration is “enforcing the immigration detention law as it was actually written to keep America safe” and claimed “judicial activists have been repeatedly overruled by the Supreme Court.”
Opposition
ACLU attorney Michael Tan praised the ruling, saying the court was correct that the administration “can’t just reinterpret the law at its own whim.” Judge Cabranes warned that Congress never intended such a radical mass-detention scheme.
Conflicting Judicial Landscape
The Second Circuit’s decision opposes Fifth and Eighth Circuit rulings that upheld mandatory detention. The split remains unresolved, and the Supreme Court has not weighed in, leaving the legal standard unsettled.
