Section 20. Appeal. Such Appeal May Be Taken by Filing an Original

complaint in such court against such city within the time named, setting forth the action of such board in respect to such assessment or award and stating the facts relied upon as showing an error on the part of such board. Such court shall rehear the matter of such assessment or award de novo, and confirm, lower or increase the same, as may seem just. In case such court shall reduce the amount of benefit assessed against the land of such property-holder ten per cent. of the assessment by said board, or increase the amount of damages awarded in his favor ten per cent. of the amount awarded by such board, the plaintiff in such suit shall recover costs, otherwise not. The amount of the judgment in such court shall be final, and no appeal shall lie therefrom.
