Iowa Code § 327C.20: Remitting penalty.

If a common carrier fails in a judicial review proceeding to secure a vacation of the order objected to, it may apply to the court in which the review proceeding is finally adjudicated for an order remitting the penalty which has accrued during the review proceeding. Upon a satisfactory showing that the petition for judicial review was filed in good faith and not for the purpose of delay, and that there were reasonable grounds to believe that the order was unreasonable or unjust or that the power of the department of transportation or the department of inspections, appeals, and licensing to make the order was doubtful, the court may remit the penalty that has accrued during the review proceeding.
