All persons interested in laying out or altering such highway may appear before said court and remonstrate against the acceptance of such report for any irregularity or improper conduct on the part of the committee, and for such a cause the court may set aside such report; but if it is of the opinion that it ought to be accepted, and if, before its acceptance, a jury is moved for to reestimate the damages and benefits or either, said court shall order a jury of six to be drawn from the boxes, in the custody of the clerk of the superior court of the judicial district, of such towns in the county, in which such judicial district is located, where the application is made as the court directs, and to be summoned and attended by a state marshal as the court directs. Such jury shall be sworn and a certificate of that fact shall be annexed to its report; and its powers shall be confined to granting relief to the person or persons making such application. The parties to this proceeding may challenge any of such jurors as in a civil action; and when, by reason of any such challenge, the panel is reduced to less than six, the clerk shall return such number of disinterested electors from any of the towns in the judicial district, except that in which such highway is located or in which the owner of the land resides, as is necessary to fill such panel; and such clerk shall, within forty-eight hours thereafter, return the names of such persons so challenged into the boxes from which they were drawn.
