The owner of any land in the drainage district or any city, township, village, district or county having control of any highway which may feel aggrieved by the apportionment of benefits so made by the commissioner, may, within 10 days after the day of review of such apportionments, appeal therefrom and for such purpose make an application to the probate court of the proper county for the appointment of a board of review, by filing with said probate court a notice of appeal and at the same time filing with said court a bond in such sum as the judge of probate may require, with 1 or more sureties to be approved by the judge of probate, conditioned upon the payment of all costs in case the apportionment made by the commissioner shall be sustained. Such appeal may be taken by the county or district road commissioners in behalf of the county, the mayor of any city in behalf of the city, by the supervisor in behalf of any township, or by the president of any village in behalf of the village when authorized by the village or city council, township board or road commission, respectively. Only 1 board shall be appointed by such probate court.
