Tex. R. App. P. 46.2
As amended through February 20, 2024
If a party makes the remittitur at the trial judge's suggestion and the party benefitting from the remittitur appeals, the remitting party is not barred from contending in the court of appeals that all or part of the remittitur should not have been required, but the remitting party must perfect an appeal to raise that point. If the court of appeals sustains the remitting party's contention that remittitur should not have been required, the court must render the judgment that the trial court should have rendered.
