On the application of the petitioner, at any time after the return day, the court may set down all objections, except the objection that the property of the objector will not be benefited to the amount assessed against it, and that said property is assessed more than its proportionate share of the cost of such improvement, for a hearing at a time to be fixed by the court, and upon such hearing the court shall determine all questions relating to the sufficiency of the proceedings, and of the benefits between the different parcels of property assessed, together with all other questions arising in such proceeding, with the exception aforesaid, and shall thereupon enter an order in accordance with the conclusions it shall reach; but such order shall not be deemed a final disposition of any such questions for the purpose of appeal, unless objectors shall waive further controversy as to the remaining questions upon the record.
