United States v. Kupfer (Elizabeth)
792 F.3d 1226
10th Cir.2015Background
- Elizabeth Kupfer and her husband under-reported over $790,000 of gross income on 2004–2006 federal returns.
- Kupfer was charged with three counts of tax evasion under 26 U.S.C. § 7201 and convicted by a jury.
- The district court instructed that guilt required willfulness; Kupfer proposed broader language excluding non-willful states (negligence, inadvertence, accident, mistake, recklessness).
- After trial, a juror affidavits referenced comments about uncharged misconduct; no hearing or mistrial was granted.
- The district court later increased the offense level for obstruction of justice under § 3C1.1, which the government concedes was error.
- On appeal, the Tenth Circuit affirmed conviction and remanded for resentencing consistent with its opinion.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Whether jury instruction on willfulness was adequate | Kupfer argued additional non-willfulness states were needed. | Kupfer contended the court should have instructed broader mental states. | Instruction was adequate; Guidry controls. |
| Whether the juror's remarks about uncharged misconduct require a hearing or mistrial | District court should have held a hearing and/or granted mistrial. | District court did not abuse discretion; remarks were harmless. | No abuse; hearing or mistrial not required; remarks harmless. |
| Whether the denial of a mistrial was proper | Extraneous remarks prejudicially affected deliberations. | Evidence against Kupfer was overwhelming; mistrial unnecessary. | Denial of mistrial within district court discretion; not reversible. |
| Whether § 3C1.1 obstruction enhancement was proper | Kupfer’s conduct could justify obstruction enhancement. | Failure to disclose is not obstruction; does not support enhancement. | § 3C1.1 enhancement improper; vacate and remand for resentencing. |
