Does Section 654 of the California Criminal Code allow for a concurrent or consecutive sentence for an act or omission that is punishable by different provisions of the law?

Section 654 provides, in relevant part: "An act or omission that is punishable in different ways by different provisions of law shall be punished under the provision that provides for the longest potential term of imprisonment, but in no case shall the act or omission be punished under more than one provision." ( 654, subd. (a).) "Section 654 does not allow any multiple punishment, including either concurrent or consecutive sentences." (People v. Deloza (1998) 18 Cal.4th 585, 592 (Deloza).)
