Background

Melvin Rivera Diaz, a Honduran citizen in removal proceedings, petitioned for habeas relief under 28 U.S.C. § 2241 while detained at the Limestone County Detention Center. He was not subject to a final removal order, and the district court had jurisdiction to consider his challenge to pre-removal-order detention.

Rivera Diaz challenged his detention without a bond hearing, asserting statutory and constitutional grounds. The court considered whether he was detained under 8 U.S.C. § 1225 or § 1226 and whether mandatory detention violated due process or equal protection.

The Court’s Holding

The court denied the habeas petition. Applying the Fifth Circuit’s decision in Buenrostro-Mendez v. Bondi, it held that Rivera Diaz was subject to mandatory detention under § 1225(b)(2)(A) because he had not shown that he was clearly and beyond a doubt entitled to admission. He therefore was not entitled to a bond hearing under § 1226(a).

The court also held that binding Fifth Circuit precedent foreclosed Rivera Diaz’s due-process challenge. It rejected his equal-protection claim because detainees covered by § 1225 are not similarly situated in all relevant respects to detainees covered by § 1226, and because mandatory detention is rationally related to the legitimate governmental purpose of preventing applicants for admission from absconding during removal proceedings.

The court denied all pending motions as moot and directed the clerk to close the case. It additionally stated that if Rivera Diaz had since received a final removal order, been removed, or been released, the petition was denied as moot.

Key Takeaways

  • Under binding Fifth Circuit precedent, a noncitizen in removal proceedings who cannot show a clear entitlement to admission is subject to mandatory detention under § 1225(b)(2)(A).
  • The court held that Fifth Circuit precedent foreclosed both a claimed right to a § 1226(a) bond hearing and a due-process challenge to mandatory detention under § 1225(b)(2)(A).
  • The distinction between § 1225 and § 1226 detainees survived equal-protection review because the groups are not similarly situated and the detention rule has a rational relationship to preventing abscondment.

Why It Matters

The decision applies two recent Fifth Circuit rulings to reject statutory and due-process challenges to mandatory immigration detention without a bond hearing. It indicates that similarly situated detainees in district courts within the Fifth Circuit face binding precedent that sharply limits relief under § 2241.

The opinion also addresses an alternative equal-protection theory, concluding that differences between categories of noncitizens and the government’s interest in ensuring attendance at removal proceedings provide a constitutionally sufficient basis for the statutory detention scheme.
