Background

Mario Alberto Z.R., a Venezuelan national, entered the United States on a B2 visa that expired on March 28, 2020. According to the petition, Immigration and Customs Enforcement officers arrested and detained him on January 20, 2026. On February 11, 2026, he received a bond hearing under 8 U.S.C. § 1226(a). The immigration judge denied his request for custody redetermination, finding he had not met his burden of showing that release would not endanger others or property and that he was not a flight risk.

Petitioner then sought a writ of habeas corpus under 28 U.S.C. § 2241, alleging that his detention is unconstitutionally prolonged under the Fifth Amendment. He asks for immediate release or a constitutionally compliant bond hearing at which the government bears the burden of justifying continued detention. Respondent moved to dismiss on June 18, 2026, arguing that Petitioner already received the process due and must first exhaust remedies, such as an appeal to the Board of Immigration Appeals. Petitioner replied on July 10, 2026. The parties do not dispute that he is detained under section 1226(a).

The Court’s Holding

In findings and recommendations dated October 14, 2026, the magistrate judge recommends that the petition be denied. The recommendation first declines to resolve the exhaustion dispute, reasoning that Petitioner does not challenge the outcome of his bond hearing but claims that his detention is unconstitutionally prolonged. It then agrees with Respondent that compliance with section 1226(a) gave Petitioner all the process to which he is entitled, noting that a bond hearing occurred on February 11, 2026, at which bond was denied on flight-risk and danger grounds.

The analysis rests on Rodriguez Diaz v. Garland, 53 F.4th 1189 (9th Cir. 2022), in which the Ninth Circuit held that due process did not require a second bond hearing, with the government bearing a clear-and-convincing burden, for a person detained under section 1226(a) fourteen months after a first hearing. The magistrate judge acknowledges that Rodriguez Diaz does not foreclose all as-applied challenges, but finds that Petitioner has not demonstrated that his case is distinguishable. A Northern District of California decision is cited for the view that following section 1226 and its regulations provides sufficient process.

Finally, the magistrate judge states that, to the extent Petitioner contests the immigration judge's factual determinations, the court lacks jurisdiction to reweigh the evidence and may only determine whether the correct legal standard was applied, citing Martinez v. Clark, 124 F.4th 775 (9th Cir. 2024). The document does not separately rule on the motion to dismiss.

Key Takeaways

  • The magistrate judge recommends denial of the petition; this is a recommendation to the assigned district judge, not a final judgment or order denying relief.
  • The recommendation treats Rodriguez Diaz as controlling for a section 1226(a) detainee who received a bond hearing, and concludes that those procedures satisfied due process here.
  • Rodriguez Diaz leaves room for as-applied challenges, but this petitioner was found not to have shown how his case differs.
  • The exhaustion argument was not decided; the recommendation says it need not be addressed because the claim targets prolonged detention rather than the bond outcome.
  • Any challenge to the immigration judge's factual findings is limited to legal-standard review, and the parties have fourteen days to file objections, failing which appellate rights may be waived.

Why It Matters

The recommendation shows how a magistrate judge in the Eastern District of California applies Rodriguez Diaz to a prolonged-detention claim by a person held under section 1226(a) after an initial bond hearing. Where that hearing occurred, the analysis is brief: section 1226(a)'s procedures satisfy due process, and a petitioner must identify a meaningful distinction from Rodriguez Diaz to obtain a new hearing with a shifted burden.

Its precedential weight is limited. These are a magistrate judge's findings and recommendations that the district judge has not yet adopted, and the decision is not a reported opinion. What remains open is whether the district judge adopts the recommendation after any objections, whether the exhaustion question will be resolved in some other case, and how courts will treat as-applied claims involving different facts. The recommendation does not order any release or new hearing.
