Any party interested may at or prior to the time fixed for hearing, file objections to the assessment roll, or any portion thereof and, after filing such objections, may be heard with reference thereto and introduce evidence thereon. The court shall hear and determine all objections except those pertaining to the amount of benefits and damages to the lands and property or the amount of compensation to be paid for lands or property sought to be taken, and may enter any proper order after such hearing.
If no demand for a trial by jury has been filed, the court shall also hear and determine all questions as to the amount of benefits and damages to lands and property without a jury, provided, however, that all questions as to the amount of compensation for lands or property sought to be taken must be determined by a jury unless a jury be waived as provided in Section 5--7.
If there are issues to be tried before a jury, then the court shall set the cause for trial, and a jury shall be summoned and impaneled as provided in Section 5--7.
