ACCA Enhancements: Categorical Approach to Marijuana Convictions and Harmless Error in Judicial Predicate Findings

Introduction

United States v. Donald Conelious Voltz, No. 22-10733 (11th Cir. Nov. 26, 2024), is a decision addressing three central issues on appeal from a Northern District of Alabama sentencing:

  • Whether Voltz’s 2001 Alabama marijuana conviction qualifies as a “serious drug offense” under the Armed Career Criminal Act (ACCA);
  • Whether that same conviction counts as a “controlled substance offense” under the U.S. Sentencing Guidelines (Guidelines);
  • Whether judicial fact-finding at sentencing to establish three predicate convictions committed on “different occasions” under ACCA violates the Sixth Amendment after Erlinger v. United States, 144 S. Ct. 1840 (2024).

The defendant, Donald Voltz, was convicted under 18 U.S.C. § 922(g) of unlawful possession of a firearm by a felon. The district court applied ACCA enhancements, sentencing him to 180 months’ imprisonment plus supervised release. Voltz appealed each enhancement and the constitutionality of the district court’s fact-finding.

Summary of the Judgment

The Eleventh Circuit affirmed. Key holdings:

  • Voltz’s 2001 Alabama marijuana conviction is categorically a “serious drug offense” under ACCA, because Alabama’s statutory definition of “marihuana” at that time mirrored the federal Controlled Substances Act (CSA) definition with no hemp exemption, consistent with United States v. Jackson, 55 F.4th 846 (11th Cir. 2022), aff’d sub nom. Brown v. United States, 602 U.S. 101 (2024).
  • That same conviction qualifies as a “controlled substance offense” under U.S.S.G. §§ 2K2.1, 4B1.2 by the categorical approach, and even if any error occurred, it was harmless because Voltz would have received the same ACCA minimum.
  • The district court’s judicial fact-finding that Voltz had three predicate convictions on “different occasions”—a matter reserved to the jury under Erlinger—was constitutional error but subject to harmless‐error review. The error was harmless because no record evidence could support a contrary finding.

Analysis

1. Precedents Cited

  • Jackson v. United States (11th Cir. 2022) and Brown v. United States (U.S. Sup. Ct. 2024): Applied the categorical approach to deem state drug convictions ACCA predicates if the state statute matched the federal CSA schedules in effect at the time of conviction.
  • Dubois (11th Cir. 2024): Held that state‐law controlled substances count under the Guidelines if regulated at the time of conviction, even if non‐federal or subsequently deregulated.
  • Apprendi v. New Jersey (2000): Mandates jury findings beyond a reasonable doubt for any fact increasing statutory maximum, except prior convictions.
  • Shepard v. United States (2005): Limits the documents judges may consult to identify elements of prior convictions.
  • Wooden v. United States (2022) and Erlinger v. United States (2024): Clarify ACCA’s “different occasions” inquiry factors and hold that judicial determination of that inquiry violates the Sixth Amendment.

2. Legal Reasoning

The court applied well‐settled categorical‐approach tests:

  1. ACCA “Serious Drug Offense” Analysis: Compare the elements of Alabama’s 2001 marijuana statute to the CSA’s schedule. Both definitions were lettering‐for‐lettering identical, with no carve-out for hemp. Under Jackson and Brown, that alignment meant the conviction qualified as an ACCA predicate.
  2. Guidelines “Controlled Substance Offense” Analysis: Under U.S.S.G. § 4B1.2(b) and § 2K2.1 commentary, state offenses punishable by >1 year for manufacturing, distribution or possession with intent to distribute qualify. Alabama’s statute met the elements, and under Dubois the court rejected a hemp‐overbreadth argument.
  3. Different‐Occasions Judicial Fact‐Finding: Erlinger requires a jury decision or defendant admission on “different occasions.” The district court found predicate offenses distinct by preponderance, a process violating the Sixth Amendment. However, because no reasonable view of the record could show the convictions occurred in a single occasion, the error was harmless.

3. Impact

This decision reinforces and clarifies several important points:

  • State drug statutes identical to federal schedules remain ACCA predicates even after federal or state definitions evolve.
  • The sentencer may apply ACCA’s mandatory minimum regardless of Guidelines calculation errors if the statutory minimum already applies, limiting harmless‐error arguments.
  • Erlinger errors—judicial fact‐finding on different occasions—are subject to harmless‐error review. Defendants challenging those findings will need to identify record evidence capable of supporting a jury’s contrary verdict on distinct “occasions.”

Complex Concepts Simplified

  • Categorical Approach: Courts compare statutory definitions, not actual conduct, to decide if a prior conviction counts as a predicate offense under ACCA or the Guidelines.
  • Shepard Documents: Limited judicial materials (e.g., plea colloquies, charging documents) used only to determine the statutory elements of prior convictions—not the broader facts of how they were committed.
  • Different Occasions Inquiry: Under ACCA, predicate convictions must occur on separate events. Factors include time gaps, physical distance, and whether the crimes share a single criminal scheme.
  • Harmless Error Review: Even constitutional errors can be upheld if the record shows the error could not have affected the outcome.

Conclusion

United States v. Voltz underscores the robustness of the categorical approach in ACCA and Guidelines enhancements, reaffirming that state statutes identical to federal definitions qualify as “serious drug” or “controlled substance” predicates. Equally important, it establishes that after Erlinger, judicial determinations of ACCA’s “different occasions” requirement—an issue reserved to juries—are not structural errors but rather discrete ones subject to harmless‐error analysis. Moving forward, practitioners must scrutinize record evidence to challenge predicate findings and remain mindful that sentencing enhancements rely heavily on statutory alignment and clear precedent.
