Tennessee Code Title 20. Civil Procedure § 20-10-103

(a) If the judgment of the trial court with regard to a remittitur is affirmed in the court of appeals, so that a party is required to make a remittitur or suffer a new trial, as in the judgment of the trial court, or if, by the opinion of the court of appeals, a further or a larger remittitur is required of the party in whose favor the verdict was rendered, or if after the case was tried in the lower court by the trial judge without a jury, or if after the case was tried in the lower court with a jury and no remittitur was suggested by the trial judge, a remittitur is first suggested or required in the court of appeals, on penalty of granting a new trial, then in each and all of these events the party in whose favor the verdict or judgment has been rendered may make the remittitur under protest in the court of appeals, and take the case, by application for permission to appeal, for review upon that point, to the supreme court.

(b) If, in the opinion of the supreme court, the verdict should not have been reduced, and the court of appeals was in error in affirming the action of the trial court as to the remittitur, or if the court of appeals was, itself, in error in suggesting a remittitur for the first time in that court, or in suggesting a further or larger remittitur than that suggested in the trial court, and if the judgment is otherwise correct, the case shall be reversed to that extent, and judgment shall be rendered in the supreme court for the full amount originally awarded by the jury or the trial judge sitting without a jury, as the case may be.
