People v. Ridley

In People v. Ridley (1965) 63 Cal.2d 671, the defendant was convicted of (among other things) robbery of victim Bennett and assault on Bennett with a deadly weapon with the intent to commit murder. (Id. at pp. 673, 677.) These crimes had different specific intent requirements: assault with the intent to commit murder required the intent to kill, whereas robbery required the intent to permanently deprive. (See People v. Burney (2009) 47 Cal.4th 203, 234.) Nevertheless, the court held that section 654 barred punishment for both, because "it appears that the assault upon Bennett was the means of perpetrating the robbery and that both offenses were incident to one objective, robbery." (Ridley, at p. 678.)
