Cal. Ins. Code § 12929
Irrespective of any provision in any law of this state the commissioner, pursuant to this code, has been and is authorized to correct: by amendment, by partial deletion, or by partial addition, any record, finding, determination, order, rule, or regulation made by the commissioner upon becoming satisfied that it is fair, just, and equitable to make the correction and that any record, finding, determination, order, rule, or regulation would have included the correction except for mistake, clerical error, inadvertence, surprise, or excusable neglect.
The correction shall only be made within a period of six months following the original action.
When the facts are within the commissioner's personal knowledge, the commissioner may, upon the commissioner's own motion and ex parte, enter an order making the correction.
Otherwise the commissioner shall enter an order of correction only after receipt and consideration of a written petition of a person described in Section 12923 or an employee of the Department of Insurance, accompanied in either case by a sworn affidavit of the facts constituting the mistake, clerical error, inadvertence, surprise, or excusable neglect relied upon to justify the correction requested. In such case the order may be made ex parte.
In either case the order shall recite the grounds and bases for the correction and shall be promptly given the same distribution, publicity, and circulation as was given the matter being corrected.
If, within 60 days following the making of the order of correction anyone objects thereto in writing, the commissioner shall set the matter for hearing, giving the same notice thereof, if any, as was given to the proceeding which gave rise to the original record, finding, determination, order, rule, or regulation.
