Casas-Castrillon After Jennings: What Remains of the Prolonged-Detention Framework

Review the primary official source.

In Casas-Castrillon v. Department of Homeland Security, the Ninth Circuit addressed years of detention while removal proceedings and judicial review continued. The opinion became an important bond-hearing authority, but its statutory framework must now be read through later Supreme Court and Ninth Circuit decisions.

The 2008 holding

The court held that detention during judicial review was governed by 8 U.S.C. section 1226(a), construed to require a hearing at which continued confinement would be justified by flight risk or danger. It relied on constitutional-avoidance concerns raised by prolonged physical restraint without individualized review.

Why later law matters

The Supreme Court’s decision in Jennings v. Rodriguez rejected similar efforts to read periodic bond-hearing requirements into detention statutes. In 2023, the Ninth Circuit in Hernandez Avilez v. Garland held that Jennings was clearly irreconcilable with the detention-authority shift used in Casas-Castrillon.

The constitutional question is distinct

The loss of the statutory construction does not itself answer every as-applied due-process challenge to unusually prolonged detention. A current petition must identify the actual detention authority, duration, procedural history, prior hearings, burdens used, delays attributable to each side, and relief requested.

Use the case with precise limits

Casas-Castrillon remains historically and analytically important, but it should not be cited as a freestanding current statutory entitlement to a Casas hearing. Current analysis must include Jennings and the Ninth Circuit’s later abrogation ruling.
