Summary
Dexter Davis, a Utah State Prison inmate, was convicted of assault by a prisoner after a physical altercation with Sergeant Vanzant.

Practice Areas & Topics
Analysis
In State v. Davis, the Utah Court of Appeals addressed when appellate courts may overturn jury verdicts based on insufficient evidence, particularly when witness testimony contains inconsistencies.
Background and Facts
While incarcerated at Utah State Prison, Dexter Davis engaged in a physical altercation with Sergeant Benjamin Vanzant. Davis was charged with assault by a prisoner under Utah Code § 76-5-102.5. At trial, two corrections officers testified that Davis was the aggressor, describing him throwing punches at Sergeant Vanzant and leaving a bruise on his arm. Davis testified that Sergeant Vanzant was actually the aggressor. The jury convicted Davis, who appealed claiming the officers’ testimony was too inconsistent and unreliable to support the verdict.
Key Legal Issues
The central issue was whether inconsistencies in witness testimony rendered the evidence insufficient to support a criminal conviction beyond a reasonable doubt. Davis argued that discrepancies in the officers’ accounts—including Sergeant Vanzant’s inability to remember which arm was struck—made their testimony inherently unreliable.
Court’s Analysis and Holding
The Court of Appeals reaffirmed that credibility determinations are the exclusive province of the jury. The court explained that appellate courts may only disregard witness testimony when it is “inherently improbable”—meaning either physically impossible or apparently false. Mere inconsistencies, even substantial ones, do not meet this standard when multiple witnesses corroborate the essential elements of the offense. Here, two officers testified to Davis’s aggressive conduct, supported by photographic evidence of Sergeant Vanzant’s bruise.
Practice Implications
This decision emphasizes the high burden for overturning jury verdicts on sufficiency of evidence grounds. Defense counsel challenging witness credibility must demonstrate that testimony is not merely inconsistent but inherently improbable. The ruling reinforces that appellate courts will not “sit as a second trier of fact” or re-evaluate witness credibility when reasonable evidence supports all elements of the charged offense.

Citation
2014 UT App 77
Court
Utah Court of Appeals
Case Number
No. 20130006-CA
Date Decided
April 10, 2014
Outcome
Affirmed
Holding
A criminal conviction based on testimony from multiple corroborating witnesses cannot be overturned for insufficient evidence merely because the testimony contains inconsistencies that do not render it inherently improbable.
Standard of Review
Sufficiency of evidence challenges are reviewed under the standard that the court may only overturn a verdict when witness testimony is so inherently improbable that no reasonable jury could find guilt beyond a reasonable doubt
Practice Tip
When challenging sufficiency of evidence on appeal, focus on whether witness testimony is physically impossible or apparently false rather than merely inconsistent, as credibility determinations are the jury’s exclusive province.
