The judgment of the court shall be conclusive upon the plaintiff and upon the defendant upon the counterclaim, but if the defendant as to the claim or the plaintiff as to the counterclaim is dissatisfied, he may, within ten (10) days of the entry of the judgment against him, make a motion for a new trial. Upon the filing of such motion for a new trial, the moving party shall pay the same fees as are charged for the filing of an original action in the Superior Court.
