State v. Eyre, 2021 UT 45 (Aug. 12, 2021)

The supreme court reversed the court of appeals, vacated the defendant’s conviction, and remanded for a new trial because the jury instruction that was given on accomplice liability to robbery did not accurately instruct the jury on the dual mens rea requirement for that crime. Accomplice liability requires a showing that the defendant had at least two culpable mental states – one to commit the underlying offense, and one to intentionally aid another person to commit it.
