121 F.4th 56
10th Cir.2024Background
- Brian Tony was convicted of two counts of witness tampering and one count of voluntary manslaughter, stemming from actions taken toward witnesses in connection with a killing on tribal land.
- A presentence report (PSR) initially grouped all three counts together for sentencing under the U.S. Sentencing Guidelines (U.S.S.G.) §§ 3D1.2(b) and (c), recommending a lower offense level.
- The district court grouped the two witness tampering counts but declined to group them with the manslaughter count, elevating Tony’s offense level and sentence.
- The government relied on uncharged obstructive conduct to justify the obstruction enhancement rather than the charged witness tampering conduct.
- On appeal, Tony argued that all three counts must be grouped together under the Guidelines, invoking the rule of lenity due to grievous ambiguity in the relevant provisions.
- The Tenth Circuit reviewed the Guidelines' language and policy, found the provisions ambiguous, and applied the rule of lenity.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Whether all three counts must be grouped under §§ 3D1.2(b) & (c) | Guidelines require grouping as conduct is closely related | Only group counts when conduct actually triggers adjustment | Guidelines ambiguous; construed in defendant’s favor |
| If uncharged conduct can be used for obstruction enhancement | Only conduct from grouped offenses should be used | Uncharged conduct can justify enhancement; limits grouping | Rule of lenity applies; group all charged counts |
| Applicability of rule of lenity to ambiguous Guidelines | Rule of lenity applies to ambiguous Guidelines provisions | Rule of lenity waived for not being raised below | Rule of lenity is not waivable; applies here |
| Effect of grouping outcome on sentencing | Lower guideline range and sentence appropriate | Higher range justified by separate handling of counts | Sentence vacated, remanded for resentencing |
