Immediately upon awarding the contract for the construction of the improvement, the clerk of any such municipality shall file a certificate in the court in which the judgment of confirmation was entered certifying to the fact that the contract has been awarded. The clerk of the court in which such judgment is rendered shall certify the assessment roll and judgment to the officers of such municipality authorized to collect such special assessment, or if there has been an appeal taken then such clerk of court shall certify such part of the judgments as is not included in such appeal. Such certificate shall be filed by the officer receiving the same in his office. With such assessment roll and judgment, the clerk of the court shall also issue a warrant for the collection of such assessment. The court may recall such warrants as to all or any part of the property affected at any time before payment of the assessment or sale of the property for payment thereof in case the proceedings be abandoned by the petitioner, or the judgment be vacated or modified, as herein provided, but not otherwise. Should an appeal be taken on any part of such judgments and the corporate authorities elect to proceed with the improvement notwithstanding such an appeal, as provided in this Division 3, the clerk shall certify such portions of such judgments appealed from time to time, in the manner above mentioned, as the final judgment is rendered thereon, and the warrant accompanying such certificate in each case shall be authority for the collection of so much of the assessment as shall be included in the portion of the roll thereto attached. The warrant in all cases of assessment under this Division 3 shall contain a copy of such certificate of the judgment describing the lots, tracts and parcels of real estate assessed so far as they shall be contained in the portion of the roll so certified and the respective amount assessed on each lot, tract or parcel of real estate, and delivered to the officer authorized to collect such special assessment.
