Does a jury have the authority to overturn a verdict of a jury in a civil case?

But having permitted the jury to come to its conclusion on the facts, the trial judge then had the right, and indeed the duty, to weigh the evidence as he saw it, and to set aside the verdict of the jury, even though supported by substantial evidence, where, in his conscientious opinion, the verdict is contrary to the clear weight of the evidence, or is based upon evidence which is false, or to prevent, in the sound discretion of the trial judge, a miscarriage of justice. Marsh v. Illinois Central Ry. Co., 5 Cir., 175 F.2d 498.
