Is a sentence imposed under section 654 of the Criminal Code by the Court of Appeal reviewable on appeal?

^2. This issue is reviewable on appeal even though Upton did not object to his sentence under section 654 in the trial court. "Ordinarily, a section 654 claim is not waived by failing to object below." (People v. Hester (2000) 22 Cal.4th 290, 295; see also People v. Perez, supra, 23 Cal.3d at p. 550, fn. 3 ["Errors in the applicability of section 654 are corrected on appeal regardless of whether the point was raised by objection in the trial court or assigned as error on appeal"].)
