Background

Gueyner Aquino Diaz, a Cuban citizen in removal proceedings, petitioned for a writ of habeas corpus under 28 U.S.C. § 2241. He remained in immigration custody without a final order of removal and sought release or a bond hearing.

The district court had jurisdiction to consider a constitutional challenge to pre-removal-order detention. The court evaluated whether Aquino Diaz was entitled to a bond hearing under 8 U.S.C. § 1226(a) and whether his continued detention without such a hearing violated the Fifth Amendment’s Due Process Clause.

The Court’s Holding

The court denied the petition. Applying the Fifth Circuit’s decision in Buenrostro-Mendez v. Bondi, it held that Aquino Diaz was subject to mandatory detention under 8 U.S.C. § 1225(b)(2)(A) because he had not shown that he was clearly and beyond doubt entitled to admission. That precedent foreclosed his claim to a bond hearing under § 1226(a).

The court also rejected the due-process challenge. Relying principally on Zadvydas v. Davis and Demore v. Kim, it reasoned that detention during ongoing removal proceedings has a definite endpoint—the conclusion of those proceedings, followed either by removal or release if the government fails to obtain a removal order. Because the detention was neither indefinite nor potentially permanent, mandatory detention without a bond hearing did not violate due process. The court denied all pending motions as moot and ordered the case closed.

Key Takeaways

  • Under binding Fifth Circuit precedent, a person in removal proceedings who cannot show a clear entitlement to admission may be detained under 8 U.S.C. § 1225(b)(2)(A) rather than afforded a bond hearing under § 1226(a).
  • The court held that detention pending completion of removal proceedings is constitutionally distinct from potentially indefinite detention after a final removal order.
  • Because Aquino Diaz’s detention had a definite termination point tied to the outcome of his removal proceedings, the court found no Fifth Amendment violation.

Why It Matters

The ruling applies the Fifth Circuit’s 2026 Buenrostro-Mendez decision to reject both statutory and constitutional challenges to mandatory pre-removal detention without a bond hearing. It signals that similarly situated detainees in Texas face binding precedent foreclosing claims that § 1226(a) requires individualized bond proceedings.

The opinion also reinforces the distinction between detention during removal proceedings and detention after a final removal order, treating the former as constitutionally permissible because it ends when the proceedings conclude.
