Background
Eunha Oh, a South Korean citizen who fled North Korea in 2012, entered the United States in September 2025 without inspection or a visa and remained in Los Angeles. On August 20, 2026, immigration officers arrested her while she attended a scheduled appointment for her asylum application and transferred her to the Adelanto ICE Processing Center. Nearly four weeks later she received a bond redetermination hearing under 8 U.S.C. § 1226(a), at which the immigration judge heard argument from her counsel, admitted her evidence over the government's objections, and denied bond after concluding under the Matter of Guerra factors that she was a flight risk.
On September 18, 2026, Oh filed a petition for a writ of habeas corpus under 28 U.S.C. § 2241, seeking immediate release or, alternatively, a new bond hearing at which the government would bear the burden of proof by clear and convincing evidence. She argued that the government violated the Fourth Amendment and 8 U.S.C. § 1357 by arresting her without a warrant, violated due process by failing to provide an initial custody determination or a predeprivation hearing, and violated due process by providing an inadequate bond hearing.
The Court’s Holding
The court denied the petition as to Counts 1, 2, 3, and 5. On the warrantless-arrest claim, it reasoned that even if the initial seizure was unlawful, Oh had not shown she would be entitled to release when her continued detention is otherwise lawful. Relying on United States ex rel. Bilokumsky v. Tod and I.N.S. v. Lopez-Mendoza, the court explained that the object of the writ is to ascertain whether the prisoner can lawfully be detained, that a civil detainee's body is never itself suppressible as a fruit of an unlawful arrest, and that a petitioner is not discharged for defects in the original arrest if a sufficient ground for detention exists. Because the IJ independently determined under § 1226(a) that Oh should remain detained as a flight risk, the alleged illegality of the arrest did not invalidate that determination.
The court also rejected the due-process claim based on the arrest at a scheduled appointment and the lack of an initial custody determination, finding that Oh did not show the postdeprivation process available to her was insufficient. Citing Rodriguez Diaz v. Garland, the court noted the government's heightened interest in immigration detention and observed that Oh received a custody redetermination hearing roughly four weeks after detention, with counsel and an opportunity to submit evidence; her disagreement with the outcome did not prove the process inadequate under Ching v. Mayorkas.
The court dismissed the challenge to the bond hearing itself (Count 4) without prejudice for failure to exhaust administrative remedies. The order explains that a noncitizen detained under § 1226(a) who is dissatisfied with an IJ's bond determination may file an administrative appeal to the Board of Immigration Appeals, and that seeking habeas review before that appeal is an improper shortcut under Leonardo v. Crawford. The court declined to excuse exhaustion based on the BIA's inability to remedy the arrest claim, the burden-of-proof challenge, or administrative delay. In a footnote, the court observed that Petitioner's contention that the government bore the burden of proof was unpersuasive because Rodriguez Vazquez v. Bostock recognizes that the detainee bears the burden at a § 1226(a) bond hearing. Even if exhaustion were excused, the court added, the appropriate remedy would be a new bond hearing, not immediate release.
Key Takeaways
- An allegedly unlawful warrantless arrest does not entitle an immigration detainee to habeas release when continued detention rests on independent statutory authority and an IJ's flight-risk determination.
- A civil detainee's body is not suppressible as a fruit of an unlawful arrest, so Fourth Amendment defects in the initial seizure do not invalidate otherwise lawful immigration detention.
- Disagreement with the outcome of a bond hearing does not establish that the postdeprivation process was constitutionally inadequate.
- A challenge to an IJ's bond determination fails for failure to exhaust administrative remedies; burden-of-proof objections and BIA delay alone do not excuse bypassing BIA review.
- The court found unpersuasive the argument that the government must bear the burden of proof at a § 1226(a) bond hearing, citing Ninth Circuit precedent recognizing that the detainee bears that burden.
Why It Matters
The order reinforces two barriers for immigration detainees seeking habeas relief in the Central District of California: Fourth Amendment challenges to warrantless arrests cannot secure release where detention is independently authorized, and bond-hearing challenges must be exhausted through the BIA before federal habeas review.
For practitioners, the case underscores that habeas petitions attacking the circumstances of an immigration arrest are unlikely to succeed as a route to release, and that exhaustion arguments premised on futility or delay face a high bar absent evidence that the agency's position is already set.
