In People v. Jerome (1984) 160 Cal.App.3d 1087, the defendant contended his plea of guilty to oral copulation with a person under 14 years of age was fatally defective because the victim was actually 15 years old. (Id. at p. 1093.) The appellate court concluded it was "legally impossible" to commit the charged crime when the victim was 15, and it modified the judgment to reflect a conviction for the lesser included offense of oral copulation with a person under 18 years of age. (Id. at pp. 1094, 1097-1098.)
