Any insurer failing, without just cause, to timely file the CGAD as required in this part is required, after notice and a hearing, to pay a civil penalty of one hundred dollars ($100) per day for each day of delay, to be recovered by the commissioner, which must be paid into the general fund of this state. The maximum penalty under this section is ten thousand dollars ($10,000). The commissioner may reduce the civil penalty if the insurer demonstrates to the commissioner that imposition of the civil penalty would constitute a financial hardship to the insurer in the commissioner’s sole discretion.
