California Public Utilities Code
(a) Except as provided in this section, no order staying or suspending an order or decision of the commission shall be made by the Supreme Court or court of appeal except upon five days notice and after hearing. If the order or decision of the commission is stayed or suspended, the order suspending it shall contain a specific finding, based upon evidence submitted to the court and identified by reference thereto.
(b) The specific finding made pursuant to subdivision (a) shall certify that great or irreparable damage would otherwise result to the petitioner and specify the nature of the damage.
(c) The Supreme Court or court of appeal may grant a temporary stay restraining the operation of the commission order or decision, other than an order or decision authorizing an increase or decrease in rates or changing a rate classification, at any time before the required hearing and determination of the application for a stay when, in the opinion of the court, irreparable loss or damage would result to petitioner unless the temporary stay is granted. The temporary stay shall remain in force only until the hearing determination of the application for a stay upon notice. The hearing of the application for a stay shall be given precedence and assigned for hearing at the earliest practicable day after the expiration of the notice.
