Background

Hamilton Douglas Lanza-Rios was convicted in the United States District Court for the Western District of Texas of illegal reentry under 8 U.S.C. § 1326(a) and (b). Following his conviction and sentencing, he appealed to the Fifth Circuit.

On appeal, Lanza-Rios raised a constitutional challenge to the sentencing enhancement provision in § 1326(b) for the first time. He argued that the enhancement violated the Sixth Amendment by permitting judges to impose increased sentences based on facts other than a prior conviction without requiring jury findings beyond a reasonable doubt.

The Government moved for summary affirmance. Lanza-Rios acknowledged that his argument was foreclosed by existing precedent but sought to preserve the issue for possible Supreme Court review.

The Court’s Holding

The Fifth Circuit granted summary affirmance and affirmed the district court’s judgment in its entirety. The court held that Lanza-Rios’s constitutional challenge was foreclosed by Almendarez-Torres v. United States, 523 U.S. 224 (1998), which established a narrow exception permitting judges to find only the fact of a prior conviction without violating the Sixth Amendment.

In reaching its decision, the court cited its own precedent in United States v. Pervis, 937 F.3d 546 (5th Cir. 2019), and the Supreme Court’s recent guidance in Erlinger v. United States, 602 U.S. 821 (2024), which reaffirmed that Almendarez-Torres persists as a controlling exception to Sixth Amendment sentencing restrictions.

The court denied the Government’s alternative motion for an extension of time to file a brief, rendering summary affirmance the appropriate disposition.

Key Takeaways

  • Almendarez-Torres remains binding precedent allowing judicial factfinding as to prior convictions in sentencing without Sixth Amendment violation.
  • The § 1326(b) sentencing enhancement for illegal reentry fits within the narrow Almendarez-Torres exception.
  • Arguments foreclosed by established Supreme Court precedent cannot proceed on appeal, even when raised for first time and preserved for Supreme Court review.
  • Summary affirmance is appropriate when appellate arguments are entirely foreclosed by binding precedent.

Why It Matters

This decision reinforces the enduring scope of the Almendarez-Torres exception in the post-Apprendi/Blakely era. While those landmark decisions expanded Sixth Amendment protections by requiring jury findings for facts that increase sentences, Almendarez-Torres carves out prior convictions as an exception—a principle the Supreme Court reaffirmed as recently as 2024. This opinion confirms that illegal reentry sentencing enhancements remain constitutional under that exception.

For immigration attorneys and criminal defense practitioners, the decision underscores the limited utility of raising Sixth Amendment challenges to § 1326(b) enhancements in the Fifth Circuit absent a change in controlling Supreme Court doctrine. Practitioners may now focus appellate efforts on other challenges or reserve arguments for potential Supreme Court petitions if the issue reaches that level.
