Is erroneous admission of evidence sufficient to overturn a conviction?

The issue we must now resolve is whether the trial court's error was prejudicial. The erroneous admission of evidence requires reversal of a conviction only if that error was prejudicial in that it resulted in a miscarriage of justice. (Evid. Code, 353.) In this context, a miscarriage of justice occurs when this court is able to say, absent the erroneously admitted evidence, it is reasonably probable the jury would have reached a result more favorable to defendant. (People v. Watson (1956) 46 Cal.2d 818, 836.)
