Unreported / Non-Citable
Background
Daniel Nicolas Mateo is a noncitizen detained at the Imperial Regional Detention Facility in California while his immigration case proceeds. He filed a federal habeas corpus petition under 28 U.S.C. § 2241, the statute that allows people in federal custody to challenge the lawfulness of their detention. He argued that he was being held without an individualized bond hearing in violation of immigration law.
This petition is one of many being filed in the Southern District of California in the wake of Maldonado Bautista v. Santacruz, a Central District of California decision that certified a “Bond Eligible Class” of immigration detainees and entered final judgment in November 2025 holding that class members are detained under 8 U.S.C. § 1226(a) — the general civil-detention statute that requires a bond hearing — rather than under more restrictive provisions that do not. The government has appealed the Maldonado Bautista judgment to the Ninth Circuit.
The Court’s Holding
The court granted the petition. The government’s response (called a “return”) conceded three critical facts: (1) Mateo is a member of the certified Bond Eligible Class; (2) final judgment has been entered as to that class; and (3) under that judgment, Mateo is detained under 8 U.S.C. § 1226(a) and entitled to an individualized bond hearing.
The court ordered the government to provide Mateo with that bond hearing before an immigration judge within seven days of the order. The court rejected any suggestion that the pending appeal of the Maldonado Bautista judgment changes the outcome, citing Ninth Circuit law that an appeal does not suspend the preclusive effect of a lower court judgment until the appeal is decided. The court denied without prejudice Mateo’s request for attorney’s fees under the Equal Access to Justice Act.
Key Takeaways
- Immigration detainees in California who fall within the certified Maldonado Bautista Bond Eligible Class can use a § 2241 habeas petition in district court to enforce their right to a bond hearing under 8 U.S.C. § 1226(a).
- The government’s appeal of the underlying class-action judgment does not delay individual relief. Under Ninth Circuit law, the lower court’s judgment continues to have preclusive effect during the appeal.
- Where the government concedes class membership and entitlement to a bond hearing, the district court will issue the order on a tight timeline — here, seven days.
- EAJA fee requests in routine class-membership habeas petitions are likely to be denied without prejudice when the government promptly concedes the relief.
Why It Matters
The Southern District of California is now processing a steady stream of habeas petitions tied to the Maldonado Bautista class judgment. For immigration detainees and their counsel, this order shows the basic playbook: file the § 2241 petition, identify membership in the Bond Eligible Class, and obtain a quick order directing a bond hearing. For the government, the order reinforces that pending appellate review does not allow it to delay providing relief to individual class members.
Beyond the immediate immigration context, the order reflects a broader principle of federal civil procedure: a lower court judgment is binding on the parties and entitled to preclusive effect during appellate review unless a stay has been granted. Practitioners in any area should be mindful of that rule when assessing how appeals affect ongoing compliance obligations.
