How is section 654 of the California Criminal Code applied in the context of a conviction for possession of a prohibited weapon?

"Case law establishes the guidelines for applying section 654 in the context of a conviction for possession of a prohibited weapon. ' "[W]here the evidence shows a possession distinctly antecedent and separate from the primary offense, punishment on both crimes has been approved. On the other hand, where the evidence shows a possession only in conjunction with the primary offense, then punishment for the illegal possession of the [weapon] has been held to be improper where it is the lesser offense." ' " (Wynn, supra, 184 Cal.App.4th at p. 1217.) Whether the unlawful possession of a firearm and the offense in which the firearm is used is indivisible depends on the facts and evidence of each case. (People v. Jones (2002) 103 Cal.App.4th 1139, 1143 (Jones).)
