Background

Petitioner, a Cuban citizen, entered the United States without inspection in 2022. After apprehension by immigration officials and service of a Notice to Appear, he was initially released on his own recognizance. Years later, immigration officials re-detained him. While detained, Petitioner requested a bond hearing, but an Immigration Judge declined to consider his request, citing lack of jurisdiction. Petitioner has no criminal history and no removal order yet became final because his timely appeal remains pending.

Petitioner’s detention must be understood against recent legal developments. In July 2025, the Department of Homeland Security and Department of Justice released interim guidance adopting a new legal interpretation of Section 235 of the Immigration and Nationality Act (8 U.S.C. § 1225), extending mandatory detention authority to all “applicants for admission,” including noncitizens who entered without inspection. The Board of Immigration Appeals adopted this position in September 2025, and the Fifth Circuit upheld the statutory interpretation in Buenrostro-Mendez v. Bondi (Feb. 2026), though that decision did not address due process claims.

The Court’s Holding

The court granted Petitioner’s petition for writ of habeas corpus, finding his detention violated his due process rights under the Fifth Amendment. The court held that Buenrostro-Mendez does not foreclose as-applied due process challenges to mandatory detention under Section 1225(b)(2), and that noncitizens retain constitutionally protected liberty interests subject to the Due Process Clause. Relying on its earlier decision in Lopez Moncebais v. Bondi and applying the Mathews v. Eldridge balancing test, the court determined that adequate procedural safeguards—including individualized determination of detention necessity—must protect Petitioner’s liberty.

The court emphasized two factors strengthening Petitioner’s liberty interest: his continuous residence in the United States since 2022 and his prior release, which created a legitimate expectation of freedom pending removal proceedings. The government did not allege that Petitioner violated conditions of release or posed a flight risk. Given these circumstances and the deprivation of adequate process, the court found the appropriate remedy was Petitioner’s immediate release rather than merely ordering a bond hearing, noting that a hearing after unjustified deprivation cannot cure the constitutional violation and that Immigration Judges may lack jurisdiction to grant such hearings under the government’s current legal position.

Key Takeaways

  • Noncitizens subject to mandatory detention under 8 U.S.C. § 1225(b)(2) retain Fifth Amendment due process rights and may bring as-applied constitutional challenges to their detention.
  • Long-term U.S. residence and prior release on own recognizance create a protected liberty interest that requires individualized justification for continued civil detention.
  • The government’s post-deprivation remedy (bond hearing) does not cure a due process violation occurring during unlawful initial detention; immediate release may be the appropriate equitable remedy.
  • The Fifth Circuit’s holding in Buenrostro-Mendez on the scope of mandatory detention authority does not resolve due process challenges in district court.

Why It Matters

This decision continues a developing line of cases in the Southern District of Texas limiting the practical effect of the government’s July 2025 shift to expansive mandatory detention authority for all applicants for admission. While the Fifth Circuit has upheld the government’s statutory interpretation, district courts across the country have held that even mandatory detention schemes must afford due process protections. This ruling adds factual weight to that principle: noncitizens with years of U.S. residence and prior lawful release status may establish a constitutionally protected liberty interest sufficient to require individualized hearings before continued detention.

The decision also reflects judicial recognition of the remedial limits of ordering bond hearings after prolonged unlawful detention. By granting immediate release rather than remanding for a hearing, the court signaled skepticism about whether post-deprivation process can adequately protect liberty interests, particularly when the administrative agency (via the BIA) has already taken a position that it lacks jurisdiction to grant bond hearings for this category of detainees. The ruling may have significant practical implications for noncitizens detained under Section 1225(b)(2) who can demonstrate substantial U.S. residence or prior release expectations.
