Within 30 days after the filing of the report of the amount and date of the first voucher issued on account of construction work done, the clerk of the court in which such judgment is rendered shall certify the assessment roll and judgment to the township collector or county collector authorized to collect the special assessment, or if there has been an appeal taken on any part of the judgment, he shall certify such part of the judgment as is not included in that appeal. This certification shall be filed by the officer receiving it in his office. With the assessment roll and judgment the clerk of the designated court shall also issue a warrant for the collection of the assessment. The court has the power to recall such warrants as to all or any of the property affected at any time before payment or sale, in case the proceedings are abandoned by the petitioner or the judgment is vacated or modified in a material respect as hereinbefore provided, but not otherwise. In case the assessment roll has been abated and the judgment reduced, the clerk of the designated court, within 30 days thereafter, shall certify the order of reduction or the roll as so reduced or recast under the direction of the court to the county collector authorized to collect the special assessment, and shall issue a warrant for the collection of the assessment as so reduced or recast.
