Is Section 654 of the California Criminal Code applicable to a single criminal offence?

Section 654 provides in pertinent part that "[a]n act or omission which is made punishable in different ways by different provisions of this code may be punished under either of such provisions, but in no case can it be punished under more than one...." A single continuous course of conduct in which several offenses are committed pursuant to a single objective gives rise to punishment for only one act under this provision. (People v. Perez (1979) 23 Cal.3d 545, 551, 153 Cal.Rptr. 40, 591 P.2d 63; see also People v. Harrison (1989) 48 Cal.3d 321, 335, 256 Cal.Rptr. 401, 768 P.2d 1078.)
