10th Cir.

United States v. Davison

June 2, 2026 ·2:24-CV-02144-JAR- ·Panel Decision ·Robert E. Bacharach · By Maria Santos

The Tenth Circuit affirmed a district court's grant of summary judgment upholding IRS tax penalties against an attorney. The court held that the district court lacked authority to amend the judgment after the appeal was filed, rendering the amended judgment a nullity.

Background

The Internal Revenue Service imposed tax penalties totaling thirty-six thousand dollars against Allen Davison, an attorney who advised a client on a tax reduction program deemed an abusive shelter. The Tax Court previously rejected Davison’s argument that the penalties were miscalculated based on his legal fees. The government later sought to reduce the penalties to a judgment in federal district court, which granted summary judgment but failed to specify the amount or the party owing the penalties. While Davison appealed, the district court amended the judgment to include the missing details, prompting the government to ask the appellate court to recognize the amended order.

The court’s reasoning

The court determined that the district court’s amendment of the judgment was unauthorized because the case was already on appeal, making the amended judgment a nullity. However, the court found it had jurisdiction over the original appeal because the omissions in the initial judgment were ministerial and did not prevent the judgment from being final. The court affirmed the summary judgment because Davison failed to challenge the district court’s reliance on issue preclusion in his briefs, despite the Tax Court having already rejected his underlying arguments.

What it means going forward

The ruling clarifies that district courts lose jurisdiction to amend judgments once an appeal is filed unless the appellate court grants specific leave. It also confirms that judgments missing ministerial details like penalty amounts remain appealable as final decisions.
