A jury is there to listen to the evidence given, and to the speeches made by counsel on both sides, and then to decide whether the charge brought against the person or persons on trial has been proved or not. Before a jury considers what its verdict or decision shall be, the judge sums up the whole case in the light of the evidence.
In a criminal case the verdict must be unanimous; that is, all twelve jurors must agree either to "Guilty" or "Not Guilty". If an agreement is come to, the foreman of the jury tells the judge what the verdict is; and the judge sentences or discharges the prisoner in accordance with the verdict. Should the jurors be divided in opinion, so that no verdict can be given, the jury is discharged, and the trial is held over again with a new jury.
