(1) Upon motion of a defendant, the court may grant a new trial for any cause which prevented the defendant from having a fair trial, or if required in the interest of justice. If trial was by the court without a jury, the court may vacate the judgment, take additional testimony and direct the entry of a new judgment. (2) Not later than ten (10) days after return of the verdict, the court on its own initiative may order a new trial for any reason for which it might have granted a new trial on motion of a defendant, and in the order shall specify the grounds therefor.
