What is the proper sentencing under section 654 of the California Criminal Code?

This court has explained the proper procedure for sentencing under section 654. (See People v. Alford (2010) 180 Cal.App.4th 1463, 1466.) "[W]hen a trial court determines that section 654 applies to a particular count, the trial court must impose sentence on that count and then stay execution of that sentence. There is no authority for a court to refrain from imposing sentence on all counts, except where probation is granted." (Ibid.) "[O]therwise if the nonstayed sentence is vacated, either on appeal or in a collateral attack on the judgment, no valid sentence will remain." (Id. at p. 1469.)
