Background
Petitioner Cesar Andres S.M. entered the United States without inspection on March 23, 2022, was detained by immigration authorities, and subsequently released on his own recognizance. He resided in Florida for several years, started a business, and serves as the sole provider for his wife and stepchildren. On February 26, 2026, he was arrested by local law enforcement for child abuse without great bodily harm, a charge that was subsequently dismissed. The following day, immigration authorities encountered and detained him at the Osceola County Jail, eventually transferring him to the California City ICE Detention Facility. At the time of his arrest, Petitioner was not subject to an order of removal; an immigration judge ordered him removed on June 9, 2026, but that order is not final because Petitioner has appealed. Petitioner filed a pro se petition for writ of habeas corpus on September 24, 2026, challenging the lawfulness of his civil detention.
Respondents contended that Petitioner is subject to mandatory detention under 8 U.S.C. § 1225(b)(2), but acknowledged that Ninth Circuit precedent holds his detention is governed by 8 U.S.C. § 1226(a) and that he is eligible for a custody redetermination hearing upon request. The Court declined to address Petitioner's additional Fourth Amendment and Administrative Procedure Act claims, finding relief warranted under the Fifth Amendment due process claim alone.
The Court’s Holding
The Court held that Petitioner possesses a protected liberty interest under the Fifth Amendment Due Process Clause. Freedom from imprisonment lies at the heart of the liberty protected by the Due Process Clause, and the government's prior decision to release Petitioner on conditions constituted an "implicit promise" that he would not be re-detained during the pendency of his immigration proceedings if he complied with the terms of his release. The Court rejected Respondents' argument that Petitioner is subject to mandatory detention under § 1225(b)(2), following Ninth Circuit precedent in Rodriguez Vazquez confirming that § 1225(b)(2) applies only to noncitizens entering at the border, while individuals like Petitioner apprehended in the interior are subject to discretionary detention under § 1226(a). Petitioner's years at liberty and the life he built in the United States create a powerful interest in his continued freedom.
Applying the Mathews v. Eldridge balancing test, the Court found that Petitioner was owed notice and a pre-deprivation hearing before a neutral decisionmaker. First, Petitioner has a significant private interest in his liberty, underscored by the substantial time he spent at liberty. Second, the risk of erroneous deprivation is considerable because civil immigration detention is nonpunitive and requires a "special justification" to outweigh liberty interests; here, Petitioner was not subject to a final removal order at the time of arrest, Respondents did not claim he is a danger or flight risk, and his only criminal charge was dismissed. Third, the government's interest in detaining Petitioner without process is low, and the burden of providing notice and a hearing is minimal because such processes are routine under § 1226(a) and its regulations. The Court granted the petition, ordered immediate release, and enjoined re-detention absent seven days' notice and a hearing where the government must prove by clear and convincing evidence that detention is justified.
Key Takeaways
- Noncitizens released on recognizance who have built lives in the United States possess a strong liberty interest protected by the Fifth Amendment Due Process Clause that cannot be extinguished without procedural safeguards.
- The mandatory detention provision of 8 U.S.C. § 1225(b)(2) applies only to arriving noncitizens at the border, not to individuals apprehended in the interior, who are governed by the discretionary detention framework of 8 U.S.C. § 1226(a).
- When removal is not imminent under a final order, the government must show a special justification for detention, and cannot detain individuals who are neither a danger nor a flight risk without a pre-deprivation hearing.
- A pending appeal of a removal order means the order is not final, and a constitutional due process claim does not evaporate with a subsequent statutory basis for detention.
- The appropriate remedy for unconstitutional immigration detention is immediate release, and re-detention requires at least seven days' notice and a hearing where the government proves by clear and convincing evidence that no alternative to detention can mitigate the risk.
Why It Matters
This decision reinforces the constitutional floor for immigration detention in the Ninth Circuit, clarifying that interior apprehensions trigger § 1226(a) protections rather than mandatory detention under § 1225(b)(2). The ruling applies the Mathews v. Eldridge framework to require pre-deprivation hearings for long-term residents released on recognizance, emphasizing that the government's prior release decision creates an implicit promise against re-detention without process. The injunction against re-detention without seven days' notice and a clear-and-convincing-evidence hearing establishes a concrete procedural safeguard that extends beyond the immediate parties. The Court's refusal to treat a non-final removal order as mooting the due process claim preserves constitutional review even as statutory detention authorities shift during litigation.
