The remonstrants shall set forth objections to the confirmation of the report of the commissioners by stating separately, first, legal objections, second, issues of fact to be tried by the court, third, issues of fact to be tried by the jury. The district court of said county shall fix a time for the hearing of the objections giving such proceedings preference over other civil actions pending, and on demand of any person or corporation assessed for the cost of construction or awarded damages, may impanel a jury and take its verdict upon the trial of such issue, whether the amount of damages awarded by the commissioners is adequate, or whether the assessment of any remonstrant demanding the review is too high, and the court or jury may assess the same. All other issues arising on remonstrance shall be tried by the court, and if the court finds that the report requires modification the same may be referred to the commissioners who may be required to modify it in any respect. The report of the commissioners shall be prima facie evidence of the allegations therein set forth and the remonstrants shall be considered as plaintiffs and have the burden of establishing their objections thereto. In any case between the commissioners and any remonstrant the court may award and apportion the costs; costs awarded against the commissioners shall be paid out of the funds realized for the assessments made.
