Before determining whether to impose either concurrent or consecutive sentences on all counts on which the defendant was convicted, the court must determine whether the proscription in section 654 against multiple punishments for the same act or omission requires a stay of execution of the sentence imposed on some of the counts. If a stay of execution is required due to the prohibition against multiple punishments for the same act, the court has discretion to choose which act or omission will be punished and which will be stayed.
