United States v. Nixon

130 F.4th 420 (4th Cir. 2025) · United States Court of Appeals for the Fourth Circuit · March 10, 2025 · No. 23-4207

Summary

This Fourth Circuit opinion reviews a district court's upward departure in sentencing a defendant convicted of being a felon in possession of a firearm. The appellate court found the sentence procedurally unreasonable because the district court improperly relied on uncharged, dissimilar post-offense disciplinary infractions to increase the criminal history category and clearly erroneously rejected unrebutted psychiatric expert testimony linking the defendant's violence to untreated bipolar disorder. The court vacated the sentence and remanded for resentencing.

Questions Presented

  1. Whether the district court erred by relying on dissimilar post‑conviction conduct for an upward departure under U.S.S.G. §4A1.3.
  2. Whether the district court failed to consider intermediate criminal‑history categories before moving from category III to VI.
  3. Whether the district court erred in rejecting unrebutted expert testimony on Nixon’s mental health.
  4. Whether the procedural errors were harmless.

Holdings

  1. The district court’s reliance on dissimilar conduct was procedurally unreasonable; the upward departure must be based on similar conduct.
  2. The district court’s jump from category III directly to VI without discussing intervening categories violated the incremental approach required by §4A1.3(a)(4)(B).
  3. The district court’s unsubstantiated rejection of the expert’s report was clearly erroneous and reversible.
  4. The procedural errors were not harmless; the sentence must be vacated and remanded.

Factual background

Nixon pleaded guilty to felon in possession of a firearm. While incarcerated awaiting sentencing he engaged in multiple violent incidents and suffered from untreated bipolar disorder, which a qualified psychiatrist diagnosed.

Procedural history

The district court sentenced Nixon to 114 months, more than double the Sentencing Guidelines range, based on upward departure under U.S.S.G. §4A1.3 relying on post‑conviction violent conduct and rejecting expert testimony. Nixon appealed.

Remand instructions

Recalculate Nixon’s criminal‑history category without improper consideration of dissimilar conduct, consider intermediate categories, and resentence consistent with the Guidelines and the expert’s recommendations.
