65 ILCS 5/9-2-56
Upon objections or motion for that purpose, the court in which the specified proceeding is pending may inquire in a summary way whether the officer making the report has omitted any property benefited and whether or not the assessment, as made and returned, is an equitable and just distribution of the cost of the improvement, first, between the public and the property, and second, among the parcels of property assessed. The court has the power, on such application being made, to revise and correct the assessments levied, to change or modify the distribution of the total cost between the public and property benefited, to change the manner of distribution among the parcels of private property, and to strike out of the roll of awards by the commissioners filed in the case the amount or amounts shown as compensation for property which property has been theretofore donated by any person or persons for the making of the proposed improvement, so as to produce a just and equitable assessment, considering the nature of the property assessed, and its capacity for immediate use of the improvement when completed.
The court may either make such corrections or changes, or determine in general the manner in which the corrections or changes shall be made, and refer the assessment roll to any competent person for revision, correction or alteration in such manner as the court may determine. The determination of the court as to the correctness of the distribution of the cost of the improvement between the public and the property to be assessed, is appealable as in other civil cases.
