What is the test for sentencing a defendant to separate terms under section 654 of the Criminal Code?

Step two of the analysis under section 654 requires us to consider whether the offenses involve multiple intents and objectives. (Corpening, supra, 2 Cal.5th at p. 311.) When, as here, "a trial court sentences a defendant to separate terms without making an express finding the defendant entertained separate objectives, the trial court is deemed to have made an implied finding each offense had a separate objective." (People v. Islas (2012) 210 Cal.App.4th 116, 129.) " 'A trial court's implied finding that a defendant harbored a separate intent and objective for each offense will be upheld on appeal if it is supported by substantial evidence.' " (Ibid., quoting People v. Blake (1998) 68 Cal.App.4th 509, 512.)
