Background

Mario Alberto Colato Gonzalez, a native and citizen of El Salvador, presented himself at the U.S. border in June 2018. After approximately ten days in detention, he was released on June 27, 2018, on conditional parole issued under 8 U.S.C. § 1226(a). An immigration judge ordered him removed from the United States on September 1, 2022, and on August 12, 2026, the Board of Immigration Appeals dismissed his appeal of that removal order. Colato Gonzalez then appealed to the Ninth Circuit, which issued a temporary stay of removal while it considers his pending motion to stay removal for the duration of the appeal.

On September 24, 2026, while driving to work, Colato Gonzalez was detained at a checkpoint. He filed a petition for a writ of habeas corpus under 28 U.S.C. § 2241 challenging the re-detention. The respondents did not contest any of his asserted facts and acknowledged that he had previously been released from immigration custody on conditional parole, but they argued that he was eligible only for a bond hearing under the Ninth Circuit's decision in Rodriguez Vazquez v. Bostock, 183 F.4th 1160 (9th Cir. 2026). In a footnote, the court also noted that Colato Gonzalez had been arrested on January 28, 2025, for alleged domestic violence but never convicted because his partner withdrew the allegation, and that the respondents neither mentioned that arrest nor argued it justified the re-detention.

The Court’s Holding

The court rejected the government's reliance on Rodriguez Vazquez v. Bostock. That decision, the court explained, involved petitioners who had been apprehended and detained by immigration authorities for the first time in the interior of the United States, and the question there was which statute governed their detention. Colato Gonzalez's situation was materially different: he had presented himself at the border in 2018, was released on parole, and complied with the conditions of his release for years.

Because of that history, the court held that he should not have been recently re-detained absent some change in circumstances, such as a changed risk of flight, danger to the community, or a change in the status of his removal case. The respondents alleged no such change and did not contest the petitioner's facts. The court therefore granted the writ of habeas corpus and ordered the respondent to immediately release Colato Gonzalez under the same conditions of release that existed immediately prior to his most recent re-detention.

The order, dated October 15, 2026, in Case No. 3:26-cv-05541-CAB-SBC in the Southern District of California, also directed the Clerk of the Court to close the case.

Key Takeaways

  • An immigrant released on parole who complies with release conditions for years cannot be re-detained without the government demonstrating changed circumstances, such as increased flight risk, danger to the community, or a change in the status of removal proceedings.
  • The Ninth Circuit's Rodriguez Vazquez decision, which addresses initial detention of unadmitted aliens apprehended in the interior, does not control cases involving re-detention of individuals previously released on parole.
  • The government's failure to contest facts or allege changed circumstances can result in immediate release rather than merely a bond hearing.
  • A prior arrest that did not result in conviction, where the government does not argue it justified re-detention, does not supply the changed circumstances required to support continued detention.
  • Habeas corpus under 28 U.S.C. § 2241 remains a viable mechanism to challenge immigration re-detention when the government cannot justify the deprivation of liberty.

Why It Matters

This decision reinforces that due process protections apply to immigration detention and that the government cannot arbitrarily re-detain individuals who have demonstrated years of compliance with release conditions. By requiring a showing of changed circumstances, the court prevents the government from using detention as a default tool rather than a justified response to specific risks.

The ruling also clarifies the limited scope of Rodriguez Vazquez, ensuring that legal standards governing initial detention decisions do not automatically apply to re-detention scenarios. This distinction protects long-term parolees from sudden, unjustified deprivation of liberty and maintains stability for immigrants who have built lives in reliance on their release status.
