Hawaii Revised Statutes Division 4. Courts and Judicial Proceedings § 635-56

In any civil case or in any criminal case wherein a verdict of guilty has been rendered, the court may set aside the verdict when it appears to be so manifestly against the weight of the evidence as to indicate bias, prejudice, passion, or misunderstanding of the charge of the court on the part of the jury; or the court may in any civil or criminal case grant a new trial for any legal cause.
