Background

Carlos Alexander Vasquez Flores, an ICE detainee, filed a habeas petition under 28 U.S.C. § 2241 challenging his ongoing detention.

The petition acknowledged that Vasquez Flores had not been admitted to the United States. The court therefore treated him as an applicant for admission subject to detention under 8 U.S.C. § 1225(b).

The Court’s Holding

Judge Andrew S. Hanen denied the habeas petition and dismissed the case. The court held that Fifth Circuit decisions in Buenrostro-Mendez v. Bondi and Sosnava Rodriguez v. Vergara foreclosed Vasquez Flores’s statutory and due-process challenges to his detention.

The court also rejected any Fourth Amendment challenge to Vasquez Flores’s arrest and detention. Section 1225(b), the court concluded, provided respondents lawful authority to detain him, so that claim could not succeed in this habeas proceeding. All remaining pending motions were denied as moot.

Key Takeaways

  • An unadmitted noncitizen is an applicant for admission subject to detention under 8 U.S.C. § 1225(b).
  • Binding Fifth Circuit precedent foreclosed the petitioner’s statutory and due-process habeas claims.
  • A Fourth Amendment challenge to arrest and detention failed because § 1225(b) supplied lawful detention authority.

Why It Matters

The order applies recent Fifth Circuit authority to summarily dismiss a § 2241 challenge to immigration detention by an applicant for admission. It also confirms that, in this posture, a detention challenge framed under the Fourth Amendment does not overcome the government’s statutory authority under § 1225(b).
