State v. Templin
In State v. Templin, 805 P.2d 182, 186 (Utah 1990), the Court found that Templin suffered prejudice as a result of his counsel's failure to offer certain witness testimony on his behalf.
The Court found that this missing testimony likely "affected the 'entire evidentiary picture.'"
And while this court conceded that it could not "discern the exact effect such testimony would have had," we concluded that it was "of sufficient import that . . . there is a reasonable probability that if these additional witnesses had been called at trial, the outcome . . . would have been different."
