Rule 3:20-1. Trial by Court or Jury

The trial judge on defendants motion may grant the defendant a new trial if required in the interest of justice. If trial was by the judge without a jury, the judge may, on defendants motion for a new trial, vacate the judgment if entered, take additional testimony and direct the entry of a new judgment. The trial judge shall not, however, set aside the verdict of the jury as against the weight of the evidence unless, having given due regard to the opportunity of the jury to pass upon the credibility of the witnesses, it clearly and convincingly appears that there was a manifest denial of justice under the law.
