Upon the review provided for in this chapter the court shall have power to affirm, modify, reverse, or annul the decision or determination reviewed, and, if necessary, to award restitution to the plaintiff, or, by mandate, direct the officer, board, commission, authority, or tribunal to proceed in the matter reviewed according to its decision. From the judgment of the district court on review an appeal may be taken in like manner and with like effect as from a judgment of such district court in a civil action.
