When the claim of any person against a city of the first class, except a tort claim as defined in section 13-903, is disallowed in whole or in part by the city council, such person may appeal from the decision of the city council to the district court of the same county by causing a written notice to be served on the city clerk within twenty days after making such decision and executing a bond to such city, with good and sufficient sureties to be approved by the city clerk, conditioned for the faithful prosecution of such appeal and the payment of all costs that may be adjudged against the appellant.
