Articulation Standards for Upward Variances in Supervised Release Revocations and Firearms Sentencing

Introduction

This commentary examines United States v. Mercado-Cañizares, 21-1903 & 22-1149 (1st Cir. Apr. 2, 2025). Jorge Mercado-Cañizares appealed two consecutive sentences imposed by the District of Puerto Rico:

a 60-month term for revoking his supervised release, and
a 48-month term for illegally possessing a machinegun under 18 U.S.C. § 922(o).

The primary issues are whether the district court gave adequate reasons for (1) a dramatic 82% upward variance from the Guidelines range on revocation, and (2) a 30% upward variance on the machinegun possession sentence.

Summary of the Judgment

The First Circuit concluded:

The 60-month revocation sentence was procedurally unreasonable because the court failed to articulate how Mercado’s case differed from the “mine-run” of supervised-release revocations. It vacated and remanded that sentence.
The 48-month § 922(o) sentence was affirmed. The court held that Mercado’s possession of 74 rounds of ammunition—50 in high-capacity magazines—provided sufficient, independently adequate justification for a 30% upward variance.

Kimbrough v. United States, 552 U.S. 85 (2007): Courts may disagree with Guideline policy, but must articulate policy-based variances.
United States v. Del Valle-Rodríguez, 761 F.3d 171 (1st Cir. 2014): An upward variance demands a clear explanation of how a case differs from the norm.

United States v. Reyes-Correa, 81 F.4th 1 (1st Cir. 2023): Reinforces the need for specific public‐record explanations of a variance.
United States v. Rivera-Berríos, 968 F.3d 130 (1st Cir. 2020): Holds that 36 rounds of ammunition did not alone justify an upward variance in a machinegun case.
United States v. García-Mojica, 955 F.3d 187 (1st Cir. 2020) & United States v. Bruno-Campos, 978 F.3d 801 (1st Cir. 2020): Confirmed that extra ammunition and multiple high-capacity magazines can justify modest upward variances.

Legal Reasoning

Revocation Sentence: Under 18 U.S.C. § 3583(e)(3), the court could impose up to 60 months. The Guidelines range was 27–33 months. The district court cited § 3553(a) factors and general aims—seriousness, respect for law, deterrence, public protection—but never explained how Mercado’s case was more severe than the “ordinary” revocation (e.g., why the Guidelines did not already account for a machinegun violation by a Class A felon). This lack of specificity violated Gall, Del Valle-Rodríguez, and Reyes-Correa.

Section 922(o) Sentence: The Guidelines ranged 30–37 months. Mercado possessed a homemade fully automatic Glock plus 74 rounds of ammunition, 50 in two extended magazines. The district court relied on:

The inherent danger of machineguns.
The added hazard of homemade automatic pistols.
The “lethalness” contributed by large ammunition supplies.
Local gun-violence statistics in Puerto Rico.
High recidivism rates among firearms offenders.

Although some factors overlap with Guidelines considerations, the ammunition quantity provided an independent and adequately explained basis for a 30% variance, consistent with Bruno-Campos and García-Mojica.

Impact

This decision clarifies two important points for future sentencing:

For supervised‐release revocations, district courts must articulate why a case falls outside the ordinary range and how each § 3553(a) factor specifically demands a variance.
For firearms offenses under § 922(o), possession of significant ammunition—especially in high‐capacity magazines—remains a valid standalone ground for modest upward variances.

Complex Concepts Simplified

Upward Variance: A sentence longer than the Sentencing Guidelines recommend.
Mine-Run Case: An average dispute that the Guidelines are designed to cover.
Procedural Reasonableness: Whether the judge followed legal rules in choosing and explaining the sentence.
§ 3553(a) Factors: Statutory factors courts must consider, including the crime’s seriousness, deterrence, public safety, and sentencing disparities.
Plain Error vs. Abuse of Discretion: Unpreserved errors reviewed only if obvious and harmful (plain error); preserved errors reviewed for a broader “abuse of discretion.”

Conclusion

United States v. Mercado-Cañizares reaffirms that:

Courtrooms need concise, case-specific explanations when imposing upward variances, especially large ones.
Failure to show how a case differs from the typical supervised-release violation warrants vacatur and resentencing.
In firearms cases, significant ammunition beyond what the Guidelines assume can independently support a limited upward variance.

This ruling will guide district courts to provide transparent, principled sentencing rationales and will help practitioners anticipate when variances are—and are not—appropriate.
