Cal. LAB § 6802

If the division makes or issues any order, decision, ruling or direction under this chapter which, in the judgment of the Public Utilities Commission, unduly and prejudicially interferes with the construction or operation of any public utility affected thereby, or with the public, or with a consumer or other patron of a public utility affected thereby, the Public Utilities Commission, of its own motion, or upon application of any utility or person so affected, may suspend, modify, alter, or annul such order, decision, ruling, or direction of the commission. The action of the Public Utilities Commission shall supersede and control the order, decision, ruling, or direction of the division previously made.
