Tex. R. App. P. 61.2

As amended through February 20, 2024
Rule 61.2 - Error Affecting Only Part of the Case

If the error affects a part, but not all, of the matter in controversy, and that part is separable without unfairness to the parties, the judgment must be reversed and a new trial ordered only as to the part affected by the error. The Court may not order a separate trial solely on unliquidated damages if liability is contested.
