(a) No action or other judicial proceeding for the enforcement of this chapter or for the collection of state taxes shall be settled except by agreement, compromise, or judgment in open court.

(b) No compromise or agreed judgment shall be entered in any such action or other judicial proceeding until there has been filed with the commissioner a verified statement setting forth the facts and showing the reasons why a compromise or agreed judgment should be entered and certifying that no agreement or settlement other than the one stated in the proposed judgment has been directly or indirectly entered into by the commissioner or by anyone for the commissioner and that the proposed judgment is, in the opinion of the Attorney General, for the best interest of the state.

(c) When any penalty is paid without the commencement of an action to recover on the penalty and the commissioner, within three years after the date of the payment, determines that the circumstances giving rise to the penalty were reasonably beyond the control of the taxpayer, the commissioner may authorize a refund of all or any part of the penalty so paid and any interest paid on the penalty.
