State v. Holland
In State v. Holland, 921 P.2d 430, 433 (Utah 1996), Holland pleaded guilty to first degree murder and was sentenced to death.
Holland later moved to vacate his guilty plea on the basis of incompetency. The trial court denied his motion, although the findings of the four experts who evaluated Holland were in conflict as to his competency.
Holland appealed. In light of the conflict between the experts, the Court found there was a "substantial question of possible doubt" as to Holland's competency and reversed the trial court. 921 P.2d at 434-35.
