Can a defendant object to double punishment under section 654 of the California Penal Code?

Section 654, subdivision (a) provides in relevant part: "An act or omission that is punishable in different ways by different provisions of law shall be punished under the provision that provides for the longest potential term of imprisonment, but in no case shall the act or omission be punished under more than one provision. . . ." "The failure of defendant to object on this basis in the trial court does not forfeit the issue on appeal. [Citation.]" (People v. McCoy (2012) 208 Cal.App.4th 1333, 1338.)

" 'The proscription against double punishment in section 654 is applicable where there is a course of conduct which . . . comprises an indivisible transaction punishable under more than one statute. . . . The divisibility of a course of conduct depends upon the intent and objective of the actor, and if all the offenses are incident to one objective, the defendant may be punished for any one of them but not for more than one.' [Citation.] 'The defendant's intent and objective are factual questions for the trial court; [to permit multiple punishments,] there must be evidence to support a finding the defendant formed a separate intent and objective for each offense for which he was sentenced. [Citation.]' [Citation.]" (People v. Coleman (1989) 48 Cal.3d 112, 162.)
